Check out a few of the things we are able to do to make your home a green home!

 

HOUSE WRAP

lifestyle wrapAs an air barrier, house wrap is an important component in the air sealing and insulating category. The system along with our professionally installed windows virtually eliminates air infiltration through the walls of your home.


The use of house wrap for the building envelope reduces the risk of water intrusion which can lead to mold growth and other potentially damaging results that may have an adverse impact on the indoor air quality. In addition, house wrap water resistive barriers mitigate the incursion of dust, pollens, pests and pollutants that can degrade indoor air quality.

WINDOWS

meter_1.jpgmeter_2.jpgLow-emittance (Low-E) coatings are microscopically thin, virtually invisible, metal or metallic oxide layers deposited on a window or skylight glazing surface primarily to reduce the U-factor by suppressing radiative heat flow. The principal mechanism of heat transfer in multilayer glazing is thermal radiation from a warm pane of glass to a cooler pane. Coating a glass surface with a low-emittance material and facing that coating into the gap between the glass layers blocks a 

significant amount of this radiant heat transfer, thus lowering the total heat flow through the window. Low-E coatings are transparent to visible light.

The pictures to the right illustrate the effectiveness of the Low-E coated windows. The left picture is of a thermometer left in a Low-E coated window at 4:00pm facing west and after five minutes had a temperature of 94 degrees. The right picture is of the same thermometer but left in a non-coated window at 4:10pm facing west and afterfive minutes had a temperature of 99.5 degrees. The two windows were in different houses next door to each other and in the same phase of construction.

R-15 BLOWN INSULATION

Unlike traditional cellulose blown insulation, this product will not settle. The blown insulation process can guarantee R-values of 15 in exterior walls with two-by-four cavities. Fiberglass batt insulation also provides R-value of 15 in two-by-four cavities, but it is difficult to fit in crevices, around doors, fixtures and outlets, so unwanted voids occur and that is where energy is lost. A blown-in installation guarantees a custom fit because the fiberglass seeks out and fills every void and increases thermal efficiency tremendously. The industry estimates energy savings of 30 to 50 percent with a blown installation.

AIR CONDITIONING

air_cond.jpgAir conditioners are manufactured to meet or exceed minimum efficiency standards set by the U.S. Department of Energy. For nearly a decade, that minimum has been 10 SEER (Seasonal Energy Efficiency Ratio). On January 23, 2006, the minimum jumped to 13 SEER, a 30% increase over the previous standard. 14 SEER equipment (used in our Green Built Homes) delivers about 8% energy savings compared to 13 SEER models.*

SEER, the Seasonal Energy Efficiency Ratio, measures energy efficiency. The higher the SEER, the greater the level of efficiency. For many homeowners, a higher SEER air conditioner will represent money saved on each month's electric bill. Exactly how much you can save will depend on the efficiency of your system as well as your individual lifestyle.

HEATING FURNACES

Furnaces are the most commonly used residential heating system in the United States, running most often on gas, but sometimes on fuel oil or electricity, and deliver their heat through a duct system. Energy Star qualified furnaces use advanced technology to deliver higher efficiency than standard new furnaces available today.

Furnace Venting proves the efficiency of the High-Efficiency furnaces used in our Green Built homes. There is so little heat loss through the vent of the High-Efficiency furnace that now PVC pipe is used for the vent pipe instead of the traditional fireproof double-walled insulated metal pipes.

PROGRAMMABLE THERMOSTATS

Did you know that properly using a programmable thermostat in your home is one of the easiest ways you can save energy, money, and help fight global warming? A programmable thermostat helps make it easy for you to save by offering four pre-programmed settings to regulate your home's temperature in both summer and winter — when you are asleep or away.

The average household spends more than $2,000 a year on energy bills — half of which goes to heating and cooling. Homeowners can save about $180 a year by properly setting their programmable thermostats and maintaining those settings. The pre-programmed settings that come with programmable thermostats are intended to deliver savings without sacrificing comfort. Depending on your family's schedule, you can see significant savings by sticking with those settings or adjust them as appropriate for you family. The key is to establish a program that automatically reduces heating and cooling in your home when you don't need as much.*

COMPACT FLUORESCENT LIGHT BUILBS

If every American home replaced just one light bulb with a compact fluorescent light bulb, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.*

Compact fluorescent light bulbs use about 75% less energy than standard incandescent bulbs and last up to 10 times longer, save about $30 or more in electricity costs over each bulb's lifetime, and produce about 75% less heat, so they're safer to operate and can cut energy costs associated with home cooling.*
