NEWER APPLIANCES CAN CUT ENERGY CONSUMPTION BY UP TO HALF

Choosing Building Components for Multifamily Buildings

Whether you are constructing a new multifamily building or renovating an existing one, the building components you choose will have a direct impact on your bottom line. Choosing energy-saving building components is an opportunity to realize substantial returns, not only in new construction or renovation projects, but also in maintenance of existing buildings.

Many multifamily buildings feature old, inefficient appliances and heating and water systems, so their energy and water costs tend to be high. Replacement of old appliances can be a substantial source of savings in multifamily buildings. New energy-efficient refrigerators, for example, consume less than half the energy needed by models ten years or older.

Efficient new boilers, improved distribution systems, and energy management systems are some of the best bets for bottom-line savings. Water-saving showerheads and faucet aerators help save on water heating.

Energy-efficient lighting can also yield fast paybacks and ongoing savings. Compact fluorescent bulbs use one-fourth the energy of standard incandescent bulbs and can be installed in common areas. A Lighting Calculator available on DOE's Federal Energy Management Program (FEMP) Web site can help you estimate potential energy savings by simply inputting your current lighting data.

Energy-efficient lighting technologies lower maintenance costs, too—these technologies last significantly longer than standard fixtures. You can also multiply your energy savings by looking beyond energy-efficient fixtures to consider centralized lighting controls, occupancy sensors, and other related energy-saving options.

For more in-depth information on energy-efficient lighting and other building technologies, see the Building Toolbox section of this site. Building Components provides a comprehensive guide to the latest information on:

• Appliances and Equipment
• Electricity
• Building Envelope: Windows, Doors, Insulation, Foundations, Framing, Roofs
• Heating and Cooling Systems
• Lighting and Daylighting
• Water Heating

A helpful guide to purchasing energy-efficient products can be found on DOE's FEMP Web site. FEMP's product efficiency recommendations include cost-effectiveness examples, buyer tips, and selection guidance. Energy cost calculators can help you estimate the lifetime energy cost savings potential of various products.
