Whether you’re a renter, homeowner or landlord who’s considering upgrading aging systems, understanding the fundamentals of home energy efficiency is important. We’re working closely with local power companies throughout the seven-state Tennessee Valley region to help people like you lower your energy bills with energy-saving recommendations, rebates and more.
Although we often think about each of these systems individually, they all work together to improve comfort, protect indoor air quality, lower your monthly heating and cooling costs, and extend the effective lifespan of your HVAC system.
That’s why we’re taking this opportunity to put everything you need to know about duct sealing, air sealing, insulation and HVAC in one place for easy reference. We hope you’ll find this comprehensive playbook useful and share it with your neighbors!
As you read through this guide, you’ll find expert-backed tips from energy authorities like ENERGY STAR, the U.S. Department of Energy (DOE), the U.S. Environmental Protection Agency (EPA), research publications and building-science standards from Air Conditioning Contractors of America (ACCA). Feel free to click around and keep on learning from trusted sources.
And don’t forget duct sealing, air sealing, insulation and HVAC maintenance all qualify for rebates from TVA EnergyRight and your local power company.
Chapter 1: Duct sealing.
Why duct sealing matters.
Wasting energy before it enters your home is hard on your home energy bills — and your personal comfort. Unfortunately, it’s an incredibly common way for energy loss to occur. Research shows that leaky ducts can lose a staggering amount of conditioned air — up to 30% — as it travels through the system.
Not only does this waste lead to higher energy bills, but it also means your HVAC system is working much harder than it needs to. Ducts leaking just 20% of conditioned air passing through them can cause your heating and cooling unit to work 50% harder!
Reading the signs.
What you can’t see can hurt your energy bill. For the most part, your home’s ductwork won’t be visible to you. However, just because you can’t see a crack or feel a leak doesn’t mean your home won’t give you some helpful signs that maintenance is needed. If any of the following symptoms sound familiar, it may be time to consult with your local heating and cooling expert.
- Higher-than-normal or unpredictable energy bills.
- Difficulty maintaining your desired temperature.
- Hot or cold spots or drafty rooms.
- Noticeable dustiness.
- Whistling or whooshing sounds when your HVAC runs.
- Dirt, dust, mold or condensation around air vents.
It may be tempting to run to your local hardware store and grab a roll of standard duct tape (quick note here: mastic sealant or metal tape are both more efficient, longer-lasting options), but unless you really know what you’re doing with your ductwork, you may want to leave maintenance to the professionals.
Best practices for duct sealing.
Use mastic sealant or foil-backed duct tape to seal all joints, seams and connections. Check out our duct sealing upgrade page for more information. Insulate ducts that run through unconditioned spaces such as your attic, crawl spaces and garage to reduce thermal loss.
When to call a duct sealing pro.
If you’re not confident in your DIY skills, if ducts run through hard-to-access areas, or need extensive sealing, a professional familiar with ACCA standards or local building codes is the way to go. If you suspect disconnections or serious leakage, you should look for a trusted expert. Plus, they’ll also have the equipment to run pre- and post-sealing leakage testing to help ensure the best results.
Chapter 2: Air sealing.
Why air sealing matters.
Air sealing is the process of closing small cracks, gaps and holes in your home’s building envelope — the barrier between indoors and outdoors. It’s especially important to have older homes inspected, but new construction shouldn’t get a free pass! As new homes settle, cracks and gaps often appear. Sealing up these gaps before winter (or summer) can dramatically reduce drafts, energy loss and discomfort.
Where to find air leaks in homes:
- Attic and crawlspace hatches.
- Window and door frames, sashes, jambs, sills.
- Plumbing and electrical penetrations (pipes, wires).
- Recessed lights, vents, fans and vent ducts.
- Around baseboards and where walls meet ceilings.
- Refrigerator, dishwasher or exhaust fan penetrations.
- Outlets, switch boxes and vent registers.
How to detect air leaks.
DIY-friendly and renter-friendly method.
For a low-cost preliminary check, you can take the DIY route. Here’s how:
- On a windy day, close all windows and exterior doors. Turn on exhaust fans (bathroom, kitchen hood).
- Light an incense stick (or use a damp hand) and slowly move around door frames, window edges, baseboards — feel or watch for air movement.
- Common leaks are at doors, windows, attic hatches, rim joists, plumbing or wiring penetrations and vents.

Why air sealing matters.
Lower energy bills: According to ENERGY STAR, air sealing and insulation can reduce heating and cooling costs by an average of 15%, and in some cases even more.
Improved comfort: Cut down on drafts, promote more stable indoor temperatures, reduce cold spots and take the burden off your HVAC systems. You can learn more about R-value (the higher the R-value, the greater the material’s insulating power) and find your climate zone on the Department of Energy’s website.
Better indoor air quality: Sealing leaks reduces infiltration of dust, pollen, mold spores, moisture and pests — which is especially relevant if vents, crawlspaces or attics are connected to living spaces.
Moisture and maintenance: Sealing leaks and home weatherization help prevent condensation, mold, mildew and structural damage from moisture infiltration.
Best practices for air sealing.
You don’t have to do everything at once! Remember, every improvement helps. To get started, we recommend focusing on key areas that can make the biggest difference.
Seal doors and windows.
- Use weatherstripping around doors and movable window sashes.
- Apply caulk to seal cracks around stationary window frames and exterior trim.
- Install door sweeps to block drafts at the bottom of exterior doors.
- Apply window film to especially drafty windows.
Address the attic and crawlspace.
- Look for gaps around plumbing vents, electrical wiring and chimneys in your attic.
- Use expanding foam or caulk to seal small holes and install covers or gaskets where needed.
- In crawlspaces, sealing gaps between the foundation and framing can stop cold air from entering your floors.
Chapter 3: Insulation.
Uneven temperatures, drafty rooms and high (or unpredictable) energy bills could mean your home is under-insulated or letting your conditioned air out and unconditioned air in!
Why insulation matters.
Insulation slows heat flow (via conduction, convection or radiation), helping keep warm air in during the winter or out during the summer months. Proper insulation reduces the load on your HVAC system and lowers energy use.
Types of Insulation.
The type of insulation you use may depend on where it’s being installed and your home’s specific needs. Some common insulation types include:
Blown-in (loose-fill) insulation
Ideal for attics and wall cavities, this type of insulation is made of fiberglass or cellulose and is blown into place using special equipment.
Batt insulation
These pre-cut panels of fiberglass or mineral wool are one of the most affordable and widely used forms of insulation. They’re ideal for open areas like between wall studs, floor joists and attic rafters.
Spray foam insulation
Expands to fill gaps and create a tight air seal. Available in open-cell and closed-cell varieties, spray foam is especially effective for sealing around pipes, wiring and small crevices.
Foam board insulation
Rigid panels made of polystyrene or polyurethane are typically used on foundation walls, basement interiors and exterior walls under siding. Foam boards offer high insulating value with a relatively thin profile.
R-value and where to insulate.
Insulation is measured in R-values, which indicate its resistance to heat flow — the higher the R-value, the better the insulation power. Visit our insulation and air sealing upgrade page for more information.
In the South, many homes are under-insulated — especially older houses. If the floor joists are exposed in your attic, for example, that’s a strong indication that you need additional insulation. Fortunately, rebates are available.
Insulation works best when the building envelope is tight. Installing insulation first, then sealing leaks, can leave gaps behind insulation or make leaks harder to find. Professionals and building-science guidance recommend sealing first, then insulating.
Here are key areas to consider for insulation:
- Attic insulation: Consider blown-in cellulose or fiberglass batt insulation to reach the recommended R-values for your region.
- Crawlspace insulation: Insulating the floor above the crawlspace can help maintain warmth on the first floor.
- Wall insulation: Harder to retrofit, but sometimes possible with dense-pack cellulose or foam injection.
You don’t always need a full insulation overhaul. Even topping off attic insulation or insulating around rim joists can make a big difference. Not sure where to begin? A member of our Quality Contractor Network can help.
For maximum efficiency, we recommend combining air sealing with insulation upgrades.
Chapter 4: HVAC maintenance
HVAC maintenance is essential for comfort, safety and efficiency — and helps prevent unexpected breakdowns when you need your system the most. We recommend scheduling a tune-up twice a year — once in fall (before heating season) and once in spring (before cooling season). Certainly, if you notice strange sounds coming from your unit and higher-than-normal bills, call in the pros regardless of whether your inspection is due or not.
If you have your home air sealed or insulated, it may be a good idea to add a tune-up to the list. Why? Because home envelope sealing may change airflow and pressure dynamics, which can affect how your system operates.
Why seasonal HVAC maintenance matters.
- Avoid costly emergency repairs — A well-tuned system is less likely to break down during extreme cold or heat.
- Improve energy efficiency: Clean systems run more efficiently and maintenance can catch issues (dirty coils, malfunctioning parts, airflow restrictions) that cause efficiency losses.
- Enhance indoor air quality: Regularly changing or cleaning filters helps trap dust, pollen and other particles rather than circulating them throughout the home.
- Extend equipment lifespan: Routine maintenance reduces wear and tear and lets you catch small problems before they become major.
- Ensure safety: Technicians can inspect for gas leaks, cracked heat exchangers, faulty wiring or improper ventilation — especially important if you have combustion appliances.
- Peace of mind: Proper airflow, clean components, calibrated thermostats — all lead to a more consistent, comfortable indoor environment.
- Take advantage of rebates: Get $50 off HVAC maintenance with a rebate from TVA EnergyRight and your local power company.
- Save money: Using less energy, helping your HVAC system last longer and taking advantage of rebates all add up to saving money.
What a typical HVAC maintenance visit should include.
Chat with your HVAC technician to make sure their inspection includes the following:
- Filter inspection/change.
- Coil cleaning (evaporator and condenser).
- Checking refrigerant levels (for cooling systems / heat pumps).
- Lubricating moving parts.
- Inspecting electrical connections and wiring.
- Testing safety controls, airflow and thermostat calibration.
- Checking defrost cycles and reversing valve in heat pumps.
Chapter 5: How to hire a qualified contractor.
Upgrades like duct sealing, air sealing, insulation and HVAC maintenance/installation often benefit from a trained, licensed and experienced contractor — especially when you want quality, safety and long-term performance.
What to look for in a trusted contractor.
We hope you’ll take advantage of our Quality Contractor Network (QCN) to find a TVA-vetted contractor near you. As you consider your options, keep the following recommendations in mind:
Licensing & insurance: Ensures compliance with state/local codes and protects you in case of accidents. (Members of the QCN are licensed and insured.)
Proven experience: Specifically, look for experience with the system and climate you have — whether that’s traditional furnaces/AC, heat pumps, ductless mini-splits or combinations.
Knowledge: They should have demonstrable knowledge of energy-efficiency standards and building science (air sealing, insulation, load calculations, duct sealing, ventilation).
Customer references and positive reviews: Look for consistency, on-time accolades and comments about professionalism, transparency and good communication.
Clear written estimates: Your quote should include labor, materials and scope of work; no vague or open-ended pricing.

Taking a break from winter? Set your home to energy-saving mode.
Save on energy costs while you’re away from home.
If you’re taking a break from winter this winter, consider setting your home to eco-mode before you hit the beaches (or the slopes). Vacation mode isn’t just a mindset, it’s also a great way to reduce energy waste and control your energy costs. Here are a few ideas to help you safely reduce energy use while you’re off enjoying life.
Happy travels!
Lower your thermostat.
It’s never a good idea to turn your heat off entirely, but if you’re going to be away for extended periods of time, you can safely adjust your thermostat down to 55-60 degrees. It’s low enough to reduce energy consumption but high enough to protect your pipes from freezing.
If you have a programmable or smart thermostat, you can schedule changes before you leave or adjust them remotely. You can even program your homecoming time so that your home is
nicely warmed up and ready for your return.
If you don’t have a smart thermostat yet, and you’re thinking about purchasing one, check to see if your local power company is participating in our Smart Thermostat Rewards program.
Protect your pipes!
You may want to consider opening bathroom and kitchen cabinets that contain plumbing — especially if they’re located on an exterior wall. This will help prevent pipes from freezing and bursting.
If you’re going to be away for a month or more, consider shutting the water supply to your home off entirely. Once you’ve turned off the supply valve, turn on a faucet inside your home to relieve pressure in the lines — this also prevents residual water from freezing. This option also eliminates the possibility of damage caused by hidden or unexpected leaks! When you return, turn the supply valve back on and allow water to flow through your taps to flush the pipes.
Adjust your water heater settings.
Speaking of water, you can also save energy by adjusting your water heater settings. Unless your home has an on-demand system, your water heater operates around the clock — even when no one’s around to use the hot water it produces. Before you leave, switch your unit to “vacation” or “away” mode (if your system has that setting) or lower the thermostat to 50 degrees.
When you return, temporarily set your system to 140 degrees for a couple of hours and then run the hot and cold taps in your home to flush out stagnant water. This is an effective way to wash away any bacterial buildup or sediment that may have accumulated.
Time your lights.
If you like to leave a few lights on for that lived-in feel, you can purchase a programmable timer with a “random” mode to convincingly vary programmed lights. While you’re at it, make sure your bulbs are energy efficient LEDs.
Unplug unused electronics.
Most microwaves, coffee makers, TVs, printers, chargers and gaming systems draw electricity even when you’re not using them — this is known as ”vampire” or “phantom” energy use. If you’re going out of town for more than a week, unplug energy-sucking appliances and gadgets.
See to your fridge and freezer.
If you’re only going to be away for a week or two, share refrigerated perishables with friends and neighbors, but leave your refrigerator running. If you’re leaving for a month or more, consider cleaning out your fridge and setting it to a warmer temperature setting or unplugging it.
Whether you’re heading out for a long weekend or for weeks at a time, turn your icemaker off and shut off the water supply to your refrigerator — this can help prevent costly ice machine repairs and/or leaky messes.
Finally, if your fridge or freezer is less than half full when you’re ready to hit the road, stock them with a few gallon jugs of cold water to help maintain proper temperature. Cold, non-perishable items — such as water jugs or bags of ice — can help maintain consistent internal temperatures when the compressor isn’t running, therefore reducing the amount of time the compressor has to operate in your absence.
Happy winter to you and yours! Enjoy your travels and travel safely.
8 energy-saving gadgets and gifts for the holidays
Give the gift of savings and comfort.
We know sweater weather is here, but let’s leave the ugly knits to your cousin Carol and light up the season with smart — and unexpected — energy-saving home technology gifts. From stocking stuffers to splashy splurges, these eight gift ideas are perfect for the gadget-lovers on your gift list.
Plug-in smart outlets: The perfect gift for multi-taskers.
Best for: The multi-tasker and the forgetful.
Cost: About $25 for a 4-pack.
Smart plugs can help your loved ones rein in energy costs in unexpected ways. Plug any on/off device like a desk lamp, fan or entertainment system into a plug-in smart switch and control it from anywhere using an app — making it great for those “Oh no! I forgot to turn off the …” moments.

Smart dimmer switches and motion detectors: A stocking-stuffer for the trend-setters.
Best for: The vibe-setter and the traveler.
Cost: About $15 per switch.
Smart dimmer switches enable your friends and family to dim groups of lights throughout their home simultaneously, or they can create an automated schedule to turn on or off when they’re not home.
Smart LED bulbs: For the mood-setters in your life.
Best for: The interior designer and the emotional chameleon (AKA: teenagers).
Cost: About $30 for a 3-pack.
Level up your friends’ LED game with smart LED bulbs. They’ll be able to program their lights to turn on when they detect motion, align brightness to circadian rhythms, select color and color temperature, and schedule or automate individual bulbs to fit their schedules — and control them all via an app or voice command.
Smart ceiling fan switch: For the dad who has everything.
Best for: The height-averse, comfort-minded and hard-to-shop-for loved ones.
Cost: About $90 per switch.
We know your ceiling fans are already running clockwise for the winter, circulating warm air from the ceiling throughout your home, but are your friends fans of the seasonal ceiling fan direction? Installing a wall switch that controls hard-to-reach ceiling fans makes seasonal adjustments a breeze. Some switches even connect to the internet, a home assistant or a smart thermostat so that the fan turns on when a room gets too hot or cold — or turns off when the room is empty.
WaterSense-certified sprinkler controller: For the gardeners who grow.
Best for: The green thumb (or the brown thumb).
Cost: About $200 for an 8-zone system.
Traditional sprinkler systems can be wasteful and inefficient. The EPA reports that WaterSense-certified smart controllers can save the average home 7,600 gallons of water each year! A Wi-Fi smart sprinkler acts like a thermostat for a sprinkler system by telling it when to turn on and off. They take the guesswork out of watering and can adjust water schedules based on hyper-local weather and soil conditions.
Water leak sensor: For the compulsive worrier.
Best for: The worrier and the controller.
Cost: About $50 for a 2-pack.
The EPA estimates that everyday household leaks in the U.S. account for about 1 trillion gallons of wasted water each year! To catch small leaks before they become costly catastrophes, give the worriers in your family a pack of smart leak sensors. They can place the sensors around washing machines, dishwashers, water heaters, toilets and any other leak-prone areas and receive a smartphone alert if a leak is detected.
Whole-home energy monitoring: For the geeks you know and love.
Best for: The data-driven homeowner and the engineer.
Cost: About $100-$300.
Whole-home energy monitors measure the amount of electricity your home uses — right down to individual circuits and devices. Although the monitor won’t help your friends reduce energy use, it will help them identify what’s consuming the most electricity so they can make informed energy decisions. Some apps even allow users to optimize the schedules of high-draw devices such as dryers, air conditioners and EV chargers so that they run during off-peak hours.

#1 — Make sure they’re licensed and insured.
Before signing a service agreement or contract, make sure your HVAC professional is properly licensed and insured. Licensing ensures they’ve met state and local requirements for training and expertise, and their insurance can protect you and your property in case of accidents or property damage during the job.
The QCN only includes licensed and insured professionals, so you can hire with confidence knowing these boxes are already checked.
#2 — Take a close look at their experience and expertise.
A trusted HVAC contractor should have a proven track record of success and experience working with your type of system — whether it’s a traditional heat pump, high-efficiency air conditioning unit, geothermal heat pump or ductless mini split heat pump.
Experienced contractors can identify potential problems more quickly, offer more accurate estimates and complete jobs efficiently.
The best contractors stay up-to-date on systems recommended by ENERGY STAR®, SEER2 ratings, home energy efficiency upgrades, rebates guidelines and the latest efficiency standards. Many are accredited by the Air Conditioning Contractors of America and participate in their Quality Assured Residential Services & Installation (RSI) program.
Energy-efficient HVAC systems can save you money over time, but only if they’re installed and set up properly. If you choose to work with a QCN member, they’ll be well-versed in the latest energy-saving technologies and can help you apply for rebates from TVA EnergyRight and your local power company.
#3 — Look for positive reviews and ask for references.
Good reputations are earned, not given. Before you hire anyone, check online reviews or ask the contractors you’re considering for customer references. Look for consistent feedback about punctuality, professionalism, communication and the quality of their work.
Contractors in TVA EnergyRight’s Quality Contractor Network are customer-reviewed and vetted for performance. When you choose a QCN member, you’re choosing a contractor trusted by your neighbors.
#4 — Be sure to get a detailed estimate.
A reliable HVAC contractor won’t surprise you with hidden fees or vague pricing. They’ll provide a clear, written estimate that outlines all expected costs. Double check they’ve included labor and materials as well as the equipment cost.
#5 — Compare bids to get the best offer.
If a contractor hesitates to give you a detailed estimate in writing, that’s a red flag! You’ll want to confirm you’ve agreed on the scope of work before signing off on the work. This also makes it easier to compare “apples to apples” bids from multiple contractors to make sure you’re getting the best deal possible.
#6 — Ask them about sizing and load calculations.
A system that’s too large or too small for your home will waste energy, and may lead to uneven temperatures, frequent repairs and a shorter lifespan.
A trusted HVAC contractor will conduct a Manual J load calculation to measure your home’s square footage, insulation levels and airflow needs. This helps them accurately determine the right system size for your home, and that your system operates efficiently and comfortably year-round.
#7 — Clear communication and honest customer care.
Good communication is key to a smooth project. Look for contractors who are proud of the service they offer. You can often tell, because they’ll take the time to answer your questions thoughtfully, explain their recommendations and walk you through every step of the process.

Don’t shy away from asking your contractor about their team’s ongoing training and certification efforts.
#9 — Look for affordable routine maintenance and service offers.
A trustworthy contractor isn’t just interested in a one-time interaction — they want to build a lasting relationship with you … and your friends and neighbors!
QCN members can also help you establish a regular maintenance schedule that ensures your system performs at peak efficiency year-round, keeping your energy bills on track and your home comfy.
#10 — Find a contractor that’s a part of your community.
Finally, look for contractors who are active members of your community. Local professionals understand the unique heating and cooling needs of our region and take pride in helping neighbors stay comfortable all year long.
From waste to watts: How General Mills turns yogurt into power.
It might sound like science fiction, but in Murfreesboro, Tennessee, yogurt waste is helping power the grid. At General Mills’ massive facility—home to iconic brands like Pillsbury and Yoplait—a clever use of dairy byproducts is reducing emissions, improving resilience and offering a model that other manufacturers could follow.
Here’s how it works — and why it matters.
What’s in yogurt waste? And why it’s powerful.
Greek yogurt production generates a significant amount of byproduct known as acid whey — a nutrient-rich liquid that’s expensive to dispose of and challenging to manage. But it also happens to be full of organic material that breaks down well in a process called anaerobic digestion.
Anaerobic digesters are machines that break down food and plant waste using tiny microbes (like bacteria) that don’t need oxygen. As the microbes consume the waste, they produce a methane-rich gas, also known as biogas, which can be used to generate electricity.
At General Mills’ Murfreesboro plant, that biogas is used to power a 1.6-megawatt generator, supplying energy right back to the facility and offsetting fossil fuel use. Even better? The leftover material (digestate) can sometimes be repurposed as fertilizer.
Sources: epa.gov; generalmills.com
Why is the Middle Tennessee plant location unique?
The General Mills site is unique not just for its size — it’s one of the largest Yoplait producers in the country — but for its on-site wastewater treatment plant. Plus, with a demand load exceeding 15 megawatts — one of only four General Mills plants globally to reach that threshold — the facility’s energy performance has a significant impact on both operational efficiency and sustainability goals. When the facility expanded to accommodate Greek yogurt production, it invested in an anaerobic digester to handle the acid whey and other organic waste.
With support from federal clean energy tax credits and strong technical assistance from Middle Tennessee Electric (MTE), the plant was able to safely integrate the generator into the grid. That partnership was essential to making the system viable — not just technically, but economically.
Daren Kaiser, Global Energy Strategy Leader for General Mills, says, “We got 40% of that cost covered by a federal rebate, but the real win was Middle Tennessee Electric’s willingness to partner with us. MTE was with us every step of the way. They probably worked harder than our contractors to make sure it came together. That kind of partnership makes innovation possible.”
What’s the impact?
The anaerobic digester is a low-emission, high-reward system that helps General Mills:
- Reduce a facility’s Scope 1 emissions (by burning natural gas).
- Save on waste disposal costs.
- Generate renewable electricity.
- Increase energy resilience for a plant that operates 24/7 and can’t afford outages.
- Keep valuable nutrients out of landfills or waterways.
The anaerobic digester at General Mills provides a powerful win-win for business and the environment. Beyond reducing Scope 1 emissions and cutting waste disposal costs, it generates clean, reliable power — perfect for a plant that can’t tolerate downtime. Plus, the digestate, a semi-solid material left over from the anaerobic digestion process, can be used as fertilizer, keeping nutrients in the loop rather than allowing them to leach into landfills or waterways.
Source: cen.acs.org
Can other industries do this, too?
Yes! Anaerobic digestion is also being used by:
- Food and beverage manufacturers (especially dairy, meat and produce)
- Breweries (spent grains and yeast waste)
- Agriculture (manure and crop waste)
- Municipalities (food scraps, sewage sludge, biosolids)
The keys to success? A consistent waste stream with sufficient volume to justify the system, and strong local utility partnerships to help manage grid integration and incentives.
For companies under pressure to meet sustainability goals without sacrificing uptime or margins, anaerobic digestion offers a compelling win-win. What starts as a byproduct of creamy Yoplait ends up fueling the plant that makes it. In a time of increasing energy demands, turning waste into energy might be one of the smartest, most scalable strategies available.

How to talk to your landlord about energy upgrades for leased spaces.
Renting your business space doesn’t mean you’re powerless when it comes to saving energy. In fact, tenants often have more influence than they realize — especially when the conversation focuses on shared benefits, such as cost savings, comfort and long-term value. Whether you’re looking to lower monthly bills, improve working conditions or enhance reliability, energy upgrades can be a win-win for both you and your landlord. Here’s how to approach the conversation with confidence.
Why energy upgrades for leased spaces matter for tenants.
If you’re dealing with rising energy bills, inconsistent temperatures or outdated lighting, you’re not alone. Many tenants in leased commercial spaces face these issues—and feel stuck because they don’t own the building. But energy upgrades can dramatically improve your day-to-day experience. Efficient lighting, smart thermostats, HVAC tune-ups and insulation improvements can all make your space more comfortable and productive, while lowering operating costs at the same time.
And the benefits go beyond the utility bill. Strategic upgrades can reduce maintenance issues, improve system reliability and even enhance employee or customer satisfaction. The key is making sure your landlord sees the value, too. Here are some steps you can take to start the conversation.
1. Understand potential roadblocks.
Tenant-landlord dynamics may impact decisions about building improvements. You may not have full authority to make changes to systems like lighting or HVAC, and your landlord may not feel motivated to invest in upgrades that primarily lower your bills — a common issue known as a split-incentive problem. You reap the savings, and they pay the upfront cost.
Short-term leases can be another barrier. Landlords might worry they won’t see a return on investment if tenants relocate before the payback period ends. But these objections aren’t deal-breakers. They’re just part of the conversation. Being prepared can help you address them head-on.
2. Identify your opportunities.
Before starting the conversation, take the time to identify specific upgrades or improvements that could make a significant impact in your space. Start with areas that offer high energy savings and fast paybacks, like:
- LED lighting uses up to 75% less energy compared to incandescent lighting.
- Smart thermostats to automate temperature control based on occupancy.
- HVAC tune-ups to improve indoor air quality, efficiency and extend system life.
- Weatherization and insulation to help stabilize indoor temperatures.
Even better: gather quick data on potential cost savings using tools like TVA EnergyRight’s incentive calculator. You can also note any performance issues like hot or cold spots, flickering lights, or equipment noise that support your case for improvements.

3. Turn talk into savings.
The best time to talk about energy upgrades is before there’s a problem—not after the HVAC system fails on a 90-degree day. Bring up the topic during a lease renewal, a property walkthrough or even a casual check-in. Come prepared with:
- A short list of potential upgrades.
- Examples from similar properties or business case studies.
- Information on available TVA EnergyRight® incentives.
Sharing success stories or information on incentives from TVA EnergyRight can make your pitch more concrete and less abstract.

4. Frame the conversation as a win-win.
Once you’ve identified your priorities, focus on how these upgrades can benefit both you and your landlord. The goal is to reframe the request as a shared investment in the property’s long-term value.
For you as a tenant, the value is clear: lower energy bills, increased comfort and more reliable operations. For your landlord, the upgrades can translate into higher building value, lower vacancy rates and a more marketable property. In today’s competitive rental market, energy-efficient buildings are becoming increasingly attractive to prospective tenants—especially those seeking modern, sustainable spaces.

5. Offer to partner in the process.
You don’t have to make the request and hope for the best — you can offer to be part of the solution. If you’re proposing larger upgrades, suggest starting small with a pilot project like retrofitting just one area with LED lighting. You can also propose a cost-sharing model or help by researching contractors, gathering quotes or completing incentive paperwork. This kind of proactive partnership can go a long way in showing your landlord that you’re serious and solution-oriented.
Another way to strengthen the landlord-tenant partnership around upgrades is through an energy-aligned lease. Instead of leaving energy use and costs to chance, these agreements build energy efficiency language directly into the lease itself. For example, clauses can allow landlords to recover a portion of capital expenses for upgrades through operating costs while ensuring tenants share in the savings.
According to the Institute for Market Transformation, energy-aligned leases can reduce utility bills by up to $0.51 per square foot and cut office building energy use by as much as 22%. In practice, this turns the split-incentive problem into a shared-investment model — landlords benefit from higher property value and improved net operating income. At the same time, tenants gain lower bills, better comfort, and more reliable systems.
Take the next step.
If your landlord is open to the idea, recommend setting up a walkthrough with your local power company or another energy expert. TVA EnergyRight can provide tools, resources and support to help identify energy upgrades for leased spaces and the available incentives.
Remember, you don’t have to navigate this alone. Even a single conversation can lead to improvements that benefit everyone who uses the space.
A win-win worth talking about.
Energy upgrades don’t just save money — they create better places to do business. And while you may not own the building, you can help shape its future. So, go ahead. Start the conversation with your landlord, focus on the mutual benefits, and come prepared with information and ideas.

5 smart strategies to improve commercial energy efficiency.
Proven strategies for building performance, budget control and resilience in commercial environments.
Commercial energy efficiency is often framed as a daunting, high-stakes challenge. Rest assured, your energy goals are attainable. The key is to start with what you can control, lean into collaboration and let quick wins fuel your long-term strategy.
In a recent panel discussion hosted by TVA EnergyRight, energy leaders offered an objective and actionable perspective on commercial energy efficiency. Featuring voices from General Mills, Metro Nashville, Middle Tennessee Electric (MTE), and Nashville Electric Service (NES), the discussion offered practical steps organizations of all sizes in both the private and public sectors can take. Here are five standout strategies — rooted in both experience and impact.
1. Prioritize utility and government collaboration.
Work with your local power company and city team, not around them.
When working in sectors such as large industrial facilities, municipalities, hospitals or universities, efficiency goals are often developed in isolation — only to run into roadblocks related to permitting, infrastructure or communication. But when utilities and city agencies are brought in early, those barriers can become opportunities.
Public-private partnerships can accelerate impact, and transparent conversations can help clarify shared goals and smooth the path forward. For example, public-sector entities like Metro Nashville are aligning energy planning efforts across more than a dozen departments by coordinating data and infrastructure planning — proving the value of early relationship-building for shared success.
“We’re often working across a very diverse set of departments, and we’re trying to create a centralized way of thinking about energy use and performance,” explains Kendra Abkowitz, Senior Director of Sustainability and Resilience, Office of Mayor Freddie O’Connell, Metro Nashville.
Utility-customer collaboration is one of the strongest predictors of success in commercial energy efficiency programs, particularly when supported by effective data sharing and technical guidance. According to Fulcrum, partnerships that unite the strengths of different sectors around shared energy goals tend to deliver better outcomes. That’s why electric utilities often team up with local governments, technology providers and community organizations to expand energy capacity and embed smarter energy management practices across operations.

2. Focus on community partnerships.
Broaden your network to broaden your impact.
Think beyond facility systems and consider where your community is already laying the groundwork for success. Partnering with local energy providers or city agencies can unlock funding, enhance resilience and help large energy users — like industrial facilities, municipalities, hospitals and commercial campuses — better serve their operations and communities. Tapping into these partnerships can unlock access to tax credits, grants and TVA programs. More importantly, it’s an opportunity to build trust and deliver a broader impact.
Public sector partnership in action: Powering Metro Nashville’s efficiency goals.
One standout example of partnership in action is the 160 megawatt (MW) solar project developed through TVA’s Flexibility program. This unique initiative allows participating local power companies to generate up to 5% of their energy load through locally sourced, cleaner energy.
In this case, Nashville Electric Service (NES) teamed up with Metro Nashville and Silicon Ranch to develop a utility-scale solar array that directly supports Metro’s ambitious sustainability goals — providing clean, renewable energy to power key municipal facilities, reduce carbon emissions and stabilize long-term energy costs.
This collaboration didn’t just result in new solar infrastructure. It demonstrated what’s possible when utilities and public sector organizations align their goals, share the planning process and leverage the financial and technical support available through TVA’s regional programs.
Industrial collaboration: General Mills’ waste-to-energy solution.
Private-sector businesses like General Mills are also embracing collaborative, circular solutions by working hand-in-hand with local utilities and city leaders. At their Murfreesboro, Tennessee, facility — home to the production of all Pillsbury Toaster Strudels and about half the nation’s Yoplait yogurt — they partnered with Middle Tennessee Electric (MTE) and leveraged federal green energy incentives to turn yogurt waste into usable power.
Together, they leveraged federal rebates to turn yogurt waste into energy, installing a 1.6 MW generator powered by methane from their on-site anaerobic digester. The project not only reduced emissions and operational costs but also improved site resilience, all of which was made possible by proactive support from the local power company.
Daren Kaiser, Global Energy Strategy Leader for General Mills, says, “We got 40% of that cost covered by a federal rebate, but the real win was Middle Tennessee Electric’s willingness to partner with us. MTE was with us every step of the way. They probably worked harder than our contractors to make sure it came together. That kind of partnership makes innovation possible.”
This type of solution — where waste becomes fuel and utilities help enable, rather than hinder, the process — demonstrates how circular systems can thrive through a shared vision and effective execution.

3. Engage communities and employees.
Efficiency starts with people, not just systems.
Many organizations focus on systems, sensors and technology while overlooking the people who use them. However, both the City of Nashville and corporate leaders on the panel emphasized the importance of engagement in building trust and long-term buy-in.
Metro Nashville gives public tours of solar installations and dashboards to make performance visible and celebrate wins. Internally, companies like General Mills are establishing “green teams” across departments and empowering employees to participate in efficiency planning. And in large systems like hospitals, facility directors and energy teams can use similar tactics — engaging both staff and the surrounding community through energy awareness campaigns as well as training and incentives for employees to identify efficiency opportunities.
Innovative energy projects can sometimes spark internal pushback, especially when other departments are facing budget constraints. Employees may question why specific initiatives move forward while their priorities are put on hold. That’s why transparency and communication are key.
Brent Baker, EVP and Chief Operations and Innovation Officer for Nashville Electric Service, notes, “When budgets are tight, people notice where the money goes. Even if it’s a different bucket, you still have to explain why one project moves forward over another. That’s real.”
Don’t underestimate the power of storytelling. Sharing before-and-after data or involving staff in pilot projects can drive broader adoption and boost your bottom line.
When it comes to employee engagement, nearly 74% of employees report that their jobs are more fulfilling when they have the opportunity to positively impact social and environmental issues. And companies with a highly engaged workforce are 21% more profitable and 17% more productive.
Whether it’s showcasing real-time dashboards, giving public tours or celebrating internal wins, making energy progress visible helps build trust and enthusiasm. The more employees and community members understand the impact of efficiency efforts, the more likely they are to support and sustain them.

4. Start with quick wins and build momentum.
Progress beats perfection.
Instead of getting stuck on your biggest energy challenge, start with what’s doable. Whether it’s lighting upgrades, HVAC optimization or low-barrier process improvements, small steps build trust, deliver results and recruit allies.
Kendra Abkowitz recommends identifying low-conflict opportunities — even if they don’t move the emissions needle right away.
She says, “Find your quick wins, so you can build momentum, but work where you have that runway and not too many barriers, even if it doesn’t always seem like the most impactful area. This can help gain allies for the work who can be helpful as you move into more challenging areas.”
These smaller successes are more than morale boosters — they can lay the groundwork for long-term change. According to the U.S. Department of Energy, low-cost or no-cost improvements, like LED lighting or thermostat adjustments, can reduce energy use by up to 20% in commercial buildings. That’s not just savings — it’s proof that efficiency works.
Cross-functional teams can accelerate this process. Brent Baker of NES recommends pairing skeptics with champions. “The lightbulb moments happen when cross-functional teams come together — when someone who’s not sure gets to see the benefit firsthand,” says Baker.

5. Scale smart: invest for resilience and carbon reduction.
Pair your momentum with long-term investment.
Once you’ve captured early wins and built internal support, the next step is to take on transformational projects that deliver lasting cost savings, operational resilience and regulatory compliance — ideally with strong utility partnerships and a clear strategy for financing and implementation.
These investments may include:
- On-site solar and battery storage.
- Waste-to-energy systems such as anaerobic digesters or combined heat and power (CHP) units.
- Fleet electrification or replacing fossil-fueled equipment with electric alternatives.
Energy-intensive facilities, including manufacturing plants, universities and hospitals, can benefit from these investments, not only to reduce emissions but also to ensure energy reliability for critical systems. For example, some healthcare facilities have already implemented combined heat and power (CHP) units to enhance energy efficiency while providing a resilient backup power source for operating rooms, ICUs and labs in the event of an outage.
While the up-front costs for these technologies can be higher, aligning with utility programs and incentive structures can dramatically improve ROI. TVA’s EnergyRight incentives, for example, have helped companies across the region accelerate their transition while staying competitive. Early coordination with your local power company can also help smooth interconnections, identify potential grid limitations and ensure operational reliability.
Investing in Carbon-Free Technologies.
At General Mills, a combination of clean energy strategies has helped them reach net-zero emissions for Scope 2 electricity use, thanks to a mix of RECs and renewable power purchase agreements. To reduce Scope 1 emissions — which are typically harder to address — they’ve implemented waste-to-energy systems at several sites, including a 1.6 MW CHP unit fueled by methane from yogurt waste at their Murfreesboro plant.
Think of Scope 1 as “on-site” emissions and Scope 2 as “purchased energy” emissions.
Why it matters.
According to the International Energy Agency, clean electricity and electrification will account for more than 50% of global CO₂ reductions needed to reach net zero by 2050. Businesses that adopt low-carbon technologies now are better positioned to address regulatory shifts, meet customer expectations and ensure future energy resilience.
It’s not just about checking a sustainability box. It’s about improving reliability, controlling costs and preparing for long-term success.

The bottom line? Balance.
From morale and momentum to grid resilience to cost savings to decarbonization, the path forward isn’t one-size-fits-all, but it is a walkable one. As panelist Robert White of MTE explained, “This next generation of customers, they’re pushing, and they don’t want to hear excuses. They want to hear commitments — at the same time, we’re trying to find that balance between reliability and affordability. We want to be part of the solution.”
Meeting energy goals in both private and public commercial sectors requires balancing performance, cost and care delivery — without compromising on reliability. As TVA’s VP, Environment and Stewardship, Michael McCall explains, “There’s no free lunch. Every energy source has trade-offs. The real goal is to stay committed, work together and keep showing up.”

Power moves: How innovative facilities turn their utility into a strategic growth partner.
Stop thinking of your local power company as just another bill to pay. Start thinking of them as one of your competitive advantages.
Rethink what your utility can do for you.
In today’s high-stakes operational environment, energy is more than a line item — it’s a strategic lever. But most facilities treat their local power company (LPC) as a background vendor.
What if, instead, you treated them like a growth partner?
Stop overlooking your most powerful business ally. From infrastructure planning to incentive stacking, your LPC can help you cut costs, boost performance and future-proof your operations. And yes — sustainability often comes baked in.
Step 1: Bring them in early, before growth becomes a challenge.
If you’re scaling, shifting or modernizing operations, your energy needs are changing — fast.
The smartest move? Loop in your LPC before you break ground or expand your process lines.
LPCs like Middle Tennessee Electric (MTE) have helped major industrials like General Mills avoid costly redesigns and power bottlenecks by modeling future load growth, flagging infrastructure gaps and helping shape more innovative expansion plans from the start.
Robert White, VP of Community Relations & Member Services for MTE, explains, “We helped General Mills integrate a 1.6 MW anaerobic digester. We were at the table from the beginning, and that helped them avoid obstacles later.”

Step 2: Tap into incentives you didn’t know you had.
Efficiency upgrades can deliver fast ROI, and in the Tennessee Valley Region, LPCs in partnership with TVA EnergyRight are willing to help you pay for them. The trouble is, too many businesses leave those dollars on the table.
From lighting and HVAC to refrigeration and advanced building controls, your LPC may offer:
- Rebates that reduce capital expenditures.
- Demand response payments to reduce peak load costs.
- Shared-risk pilot programs for new technologies.
Vanderbilt University Medical Center, for example, received a $243,000 TVA EnergyRight incentive through Nashville Electric Service (NES), which is now delivering $200,000+ in annual savings.

Step 3: Use utility data to benchmark, optimize and scale.
Your LPC has visibility across sectors, regions, and use profiles. That means they know what “good” looks like — and where your facility may be falling short.
“We can bring benchmarking data to the table. That’s the power of working with an LPC that knows the territory,” says Brent Baker, EVP and Chief Operations and Innovation Officer, NES.
By sharing load data and operational goals, you can uncover:
- Inefficiencies you didn’t know existed.
- Time-of-use strategies to reduce spend.
- Long-term energy models that align with your growth targets.
Source: energy.gov
Step 4: Reduce the risk for big ideas with a technical ally.
Innovation always carries risk — but your LPC can help you sell it to your team and manage it.
Whether you’re exploring on-site generation, EV fleet planning or battery storage, utilities can support you with:
- Interconnection guidance.
- Reliability modeling.
- Regulatory navigation and incentive layering.
General Mills has achieved net-zero Scope 2 emissions globally. With help from MTE, they integrated a 1.6 MW generator powered by yogurt waste — an anaerobic digester that cut emissions and costs while increasing energy independence.

Calling all junior detectives! Use your sleuthing skills to spot sneaky leaks.
Is it a GHOST or a drafty window? Did a BLACK CAT just cross your path, or is there a breeze sneaking in under a door? Is your bedroom HAUNTED, because it’s always chilly — even when the heat’s on? If any of this sounds familiar, there may be energy mysteries in your home — and YOU can help solve them.
Here’s what you’ll need in your energy sleuth’s detective kit:
- Post-it notes (Write: “BOO! An energy ghost lives here!” on at least 12 of them)
- Craft feathers (the feathery the better!)
- Flashlight
- Thermometer (optional, for comparing room temps)
Ready for your first mission? Grab your energy sleuth’s detective kit and your grown-up because we’re going on a home energy ghost hunt.
Mystery #1: The ghost in the window.
Windows let you keep a friendly eye on the world outside, but sometimes they let in more than you’re bargaining for.
DETECTION: On a windy day — the windier the better! — grab the lightest feather from your kit. Very slowly move the feather around the edges of every window in your house. It’ll help you detect unwanted airflow around window frames, doors, baseboards, electrical outlets, crawlspaces, registers, and attic doors.
When your feather is “tickled” you’ve found a draft ghost! Sound the alarm (we recommend a ghoulish howl) and mark it with a BOO note.
Fresh out of feathers? Run your hand under cold water and you’ll be able to feel the ghostly drafts for yourself!
SOLUTION: For a low-cost fix, your grown-up partner can use clear weatherstripping or a window insulation kit to seal the gaps and keep warm air inside. For more hot tips on air sealing and insulation, be sure to check out this article!
Mystery #2: The case of the chilly door.
DETECTION: Make a list of all the doors in your home — front door, back door, sliding door, side door. Do any of them feel colder near the bottom? Can you see light coming in around the edges? Take a piece of paper and close it in the door. Then, try pulling it out. If it slides out easily, air is probably slipping through there, too!
SOLUTION: Add a door sweep or a rolled-up towel to block the draft. Feeling crafty? You can make and decorate your own “draft snake.”
Mystery #3: The clue of the cold floor.
DETECTION: On a chilly day, take your socks off — if you dare! — and walk around your home. Pay extra close attention to areas where your toes feel chilly. If you feel a cold spot, mark it with a BOO note.
SOLUTION: Ask your grown-up if you can help them pick out a few area rugs. You can even grab your flashlight and head down to your basement or crawlspace to look for leaks. Insulation and air sealing can help stop chilly floors.
Mystery #4: The secret of the whistling outlets.
Did you know cold air can sneak in through electrical outlets? Especially on outside-facing walls!
DETECTION: On a windy day, place the palm of your hand gently over light switches or outlets near exterior walls. Feel a tickle of air? That’s a hidden leak! Mark it with a BOO note.
SOLUTION: Encourage your grown-ups to take you on a field trip to your local hardware store to buy outlet gaskets. These inexpensive insulating foam pads go behind outlet covers — they’re easy to install and super helpful.
