“Rooftop units (RTUs)”
Nationwide Retail Chain Puts an Emphasis on Efficiency
This E Source case study from the retail buildings sector was created for the Business Energy Advisor.
Small and Midsize Offices
Small and midsize office buildings in the US (those under 100,000 square feet) use an average of 15 kilowatt-hours (kWh) of electricity and 38 cubic feet of natural gas per square foot annually.
Retail buildings in the US use an average of 18.3 kilowatt-hours (kWh) of electricity per square foot and 34,300 Btu of natural gas per square foot annually. Typically, lighting, cooling, and heating are the best targets for energy savings.
Quick-service restaurants (QSRs) are some of the most energy-intensive buildings in the US. Refrigeration, lighting, and cooling, collectively, represent about 63% of total energy use in QSRs, making those systems the best targets for energy savings.
Packaged Rooftop Air Conditioners
Most commercial buildings use rooftop units (RTUs) for cooling, but choosing the right equipment and keeping it maintained can be overwhelming. This article guides you in selecting the best one for your application and lists maintenance tips to keep your RTU running efficiently.
Municipal Government Facilities
Municipal governments oversee large and small administrative buildings, libraries, indoor and outdoor recreation centers, schools, and wastewater treatment facilities. Learn how these buildings use energy and how they can be more efficient.
Reducing energy consumption is one way to improve both the profitability and the value of any property, and there are plenty of opportunities for property managers to reduce energy consumption and improve the bottom line for their properties and clients.
Manufacturing processes use a great deal of energy but can benefit from energy-saving strategies. Learn how to create energy savings that can reduce costs while improving process reliability.
Large office buildings (those over 100,000 square feet) spend nearly 29% of their operating expenses on utilities, mostly electricity and natural gas. Learn about some great short- and long-term measures that can help large office buildings save energy and boost their bottom line.
In a typical school building, space heating, cooling, and lighting together account for nearly 70% of school energy use. Plug loads (such as computers and copiers) constitute one of the top three electricity end uses, after lighting and cooling.
Heat Pump Water Heaters
By pulling heat from the surrounding air, heat pump water heaters can more than halve your water heating costs. This article explains what you need to know about this energy-efficient technology and how to make the best choice when considering a new purchase.
Although energy represents only about 1% of total grocery store costs, it’s approximately equal to a typical grocery’s profit margin, so a 10% reduction in energy costs can mean a 10% increase in profits.
Energy Management and Information Systems
Installing or upgrading a building automation system (also known as an energy management system) can save between 5% and 15% of overall building energy consumption. Learn how to reduce overall building operating costs by controlling building equipment so that it operates more efficiently.
A tremendous amount of energy is wasted ventilating spaces unnecessarily. Demand-controlled ventilation regulates the amount of outside air drawn in based on a building's actual occupancy, and can save as much as $1.00 per square foot annually. Find out if this approach will be effective for you.
Congregations at houses of worship vary dramatically; so do their energy needs. Large or small, these facilities present many low- and no-cost opportunities for saving energy.
Colleges and Universities
US colleges and universities use an average of 18.9 kilowatt-hours (kWh) of electricity and 17 cubic feet of natural gas per square foot (ft2) annually, and typical US higher-education buildings sized around 50,000 ft2 consume more than $100,000 worth of energy each year.
