Building Envelope. On average, a typical family can spend as much as
$680 per year to heat and cool its home. This brief explains why this
expense is not necessary, even in extreme climates, and can be reduced
by up to 50 percent through investment in building envelope improvements
such as sealing air leaks, adding adequate insulation, and upgrading
window features
Lighting. There are many lighting designs and technologies available
today that can not only meet all your lighting needs, but can do so
using less electricity. This Brief details a few steps to make your home
lighting more energy efficient while maintaining and improving lighting
quality
Space Cooling. Space cooling typically accounts for 13 percent of total
energy use, costing homeowners an average $197 per year. A
well-insulated and tightly sealed home that uses the natural movement of
heat and air to maintain comfortable indoor temperatures can reduce
cooling costs by up to 50 percent while also saving on heating bills.
This brief outlines how to first minimize the amount of heat that enters
and is generated inside the home, and then, if additional cooling is
still needed, take steps to increase the efficiency of cooling equipment
and/or buy new, more efficient equipment.
Space Heating. Space heating costs the average homeowner $480 per year
and accounts for about 32 percent of the total energy bill. This brief
details how a well-insulated, tightly constructed home can require
little supplementary heating, and how retrofit measures that minimize
heat loss can reduce heating requirements even in old, leaky homes.
Water Heating. Water heating accounts for approximately 19 percent of
total home energy use and costs an average household over $300 a year.
This brief outlines the many things you can do to cut your water heating
costs, including using hot water more efficiently, switching to
water-efficient shower and faucet fixtures, and making a few simple
adjustments to your existing heater.
Cleaning Appliances. Dishwashers, clothes washers, and dryers are among
the most energy-intensive appliances in the home, costing the average
household about $150 annually to power them. This brief points out
efficient models that are available today and that can actually produce
cleaner clothes and dishes while using less energy and water.
Electronics Home office equipment, audio and video systems, and
miscellaneous electronics consume almost 20 percent of all electricity
used inside the average home and can cost as much as $175 per year to
operate. This brief shows that while buying more efficient electronic
devices can save some of this energy and money, changing how you use the
equipment is more effective.
Kitchen Appliances. Having an energy efficient kitchen means
understanding the energy consumption of the appliances in your kitchen,
the energy life cycle of the food that comes into it, and all of the
wastes that leave it. No matter what your lifestyle is, there are
numerous energy efficient practices that you should consider. The
options in this brief range from locating your refrigerator away from
heat sources, to sizing appliances to match the job to be done, to
considering your food disposal habits.
Whole System Design This brief introduces the powerful tool of whole
system design within the context of the building envelope - introducing
the synergies that exist between thermal mass, windows, and other
components of passive solar design. Whole system or integrated building
design actively considers the interconnections between systems,
occupants, and the environment, and uses these connections to develop
single solutions to multiple problems (shelter, energy savings,
aesthetics, natural daylight, indoor environmental quality,
affordability, etc.)
