kitchen sinks is often excluded because of the high food & grease content. |
Ground Source Heat Pump (Geothermal heat pumps/geothermal heat exchange) |
Ground source heat pumps (GSHPs) are electrically powered systems that tap the stored energy of the
earth. These systems use the earth's relatively constant temperature to provide heating, cooling, &
hot water. |
High Efficiency Furnace / Boiler |
The Federal Trade Commission requires new furnaces or boilers to display their AFUE so consumers
can compare heating efficiencies of various models. AFUE is a measure of how efficient the appliance
is in the energy in its fuel over the course of a typical year. |
High Efficiency Lighting (CFLs, LED) |
New lighting technologies use less energy, last longer, & give off the same amount of light as old
incandescent technologies. Compact fluorescent lights (CFLs) use about a quarter of the energy while
giving off the same amount of light & lasting up to 10 times longer. Light-emitting Diodes
(LEDs)create light without releasing heat, last longer than CFLs & do not contain mercury. |
High Efficiency Water Heater |
High efficiency water heaters use 10 to 50 percent less energy than standard models. Models with an
ENERGYSTAR rating are considered highly efficient. |
High SEER Air Conditioning |
Air conditioners manufactured after January 26, 2006 must achieve a Seasonal Energy
Efficiency Ratio (SEER) of 13 or higher |
Home Orientation (South Facing Overhangs) |
The home is located on the property to maximize solar gain in winter, & provide shade in summer.
In general, a south-facing orientation, within 30° east or west of true south, will provide around
90% of the maximum static solar collection potential. |
Home Performance with ENERGY STAR® |
Home Performance with ENERGYSTAR is a national program administered by the U.S.
Environmental Protection Agency (EPA) & the U.S. Department of Energy (DOE). It offers a
comprehensive, "whole-house" approach to improving energy efficiency & comfort of existing
homes. |
Hot Water Recirculation Pump /
Structured Plumbing |
Hot water recirculation systems use a pump to move hot water through the plumbing system from the
water heater to near the fixtures. Structured Plumbing is a method of designing the hot water
plumbing layout to minimize hot water delivery times. |
ICF |
Rigid plastic foam forms that hold concrete in place during curing & remain in place afterwards to
serve as thermal insulation for concrete walls. The foam sections are lightweight & result in energy
efficient, durable construction |
Indoor air PLUS
By ENERGYSTAR® |
A variety of construction practices & technologies to decrease the risk of poor indoor air quality.
The
Environmental Protection Agency administers a builder program called Indoor air PLUS. |
Improved Insulation |
Building codes typically require a minimum insulation level for each component of the building
envelope. Improved Insulation refers to increasing the insulation levels beyond the minimum code
requirements. |
Insulation Air Sealing Upgrades |
For existing homes, Insulation & Air Sealing upgrades are typically implemented in conjunction with
an energy audit. These steps help seal a home from drafts & leakage, & increase the insulation
levels
of the home. |
Low Flow Fixtures / Shower Heads |
A faucet with aerator installed to reduce the flow of water but not reduce water pressure. Low-flow
shower heads use about 2 ½ gallons of water per minute compared to between four & five gallons per
minute used by conventional heads. |
Low Flow Toilets |
A toilet that uses less water per flush when compared to the current federal requirements. Such
toilets
often have the EPA's WaterSense label. In general, low-flow toilets use a maximum of 1.28 gallons of
water per flush. |
Low-water Sod |
Landscaping that has significantly lower watering requirements than conventional turf. Most of
these types come with certificates of installation in Colorado. |
No Formaldehyde Certified Cabinetry |
The Kitchen Cabinet Manufacturers Association (KCMA) created the Environmental Stewardship
Program (ESP) to help cabinet manufacturers demonstrate their commitment to environmental
sustainability & help consumers easily identify environmentally-friendly products. |
No or Low VOC Paint |
Paints that release no, or minimal Volatile Organic Compound (VOC) pollutants, & are virtually odor
free. |
Orientation / Passive Solar Design |
Solar geometry, window technology & local climate are used to direct building design. Helps reduce
or even eliminate the need for mechanical cooling & heating & daytime artificial lighting. |
Programmable Thermostat |
A thermostat that can be programmed to increase &decrease a home's temperature setting
automatically. |
Radon Mitigation System |
A system that detects radon, a naturally occurring gas, colorless &odorless, that causes adverse
health
effects. Radon gas often enters a structure by seeping through cellar walls & floors. |
Reclaimed Flooring |
Material that is recovered for reuse or another purpose, such as wood barn siding hat becomes
flooring. |

SEER Rating |
The rating & performance standard developed by the U.S. government & equipment manufacturer's
to produce an energy consumption rating that is easy to understand by consumers. The lower the
SEER rating, the more energy required to produce the desired effect. |
SIPS |
Panels made from a thick layer of foam sandwiched between two layers of Oriented Strand Board
(OSB), plywood or fiber-cement. They are an alternative to the foam core & are available with a core
of agriculture fibers (such as wheat straw) thatprovides similar thermal & structural performance.
|
Straw Bale |
A construction method that uses waste straw left over from crops, such as wheat, oats, barley, rye,
rice
& flax, after all the food has been extracted. Straw is gathered, baled, compressed & tied together.
Bales
are placed over a "stemwall" to protect the straw from the ground soil & the straw bales are
stuccoed &
plastered over for finishing. |
Sustainable Flooring |
Sustainable flooring is produced from sustainable materials (& by a sustainable process) that
reduces
demands on ecosystems during its life-cycle. This includes harvest, production, use & disposal. |
Tankless/On Dem & Water Heater |
A system that delivers hot water at a preset temperature when needed, but without requiring the
storage
of water. The approach reduces or eliminates energy standby losses. Tankless water heaters can be
used
for supplementary heat, such as a booster to a solar hot water system, or to meet all hot water
needs.
Tankless water heaters have an electric, gas, or propane heating device that is activated by the
flow of
water. |
