General project overview:
It had been our dream for years to build a home. So in March of 2016 this dream became a reality. We planned for this home for approximately 5 years, researching how to build a zero energy home, from insulation and windows, to siding and roofing. We wanted a home with as little long term costs as possible. We attended home shows and did online research to discover what was available in the market to help achieve our dreams and goals.
Our foundation consists of R21 ICF (Insulated Concrete Forms) This allows us to heat and cool our basement with very little energy. Geothermal heating and cooling in our home, using energy from the ground so we don’t need a fuel source. We also have Solar Photovoltaics which provides power for our house and well. Our south and west facing windows will allow for natural energy during the winter months. Our home was specifically designed to have no ductwork penetrations in the attic so there would be no heat or cooling loss.
Orientation and Envelope: (windows, insulation, framing)
Our home is a ranch style. We used Harvey vinyl Double Low-E RS E Star 6.0 2015 windows. The outside walls are 2x6 framing. There is zip plywood on the roof. We specifically designed our home so that there is no ceiling penetration for the duct work. For insulation we used R-49 fiberglass blow for the ceiling area. For exterior walls, we used R-24 BIBS. For band joists, box sill RIM joists we used R-21 15” high performance unfaced batt. For air infiltration around the entire house we used Energy Complete Sealant. Around all windows and doors, we used Insulation Foam Sealant. The garage exterior walls were insulated with R-21 15” high performance unfaced batt, and the garage ceiling was R-39 fiberglass blow. Under the basement and garage floor, we put Prodex R-16 Total Under Concrete Insulation which is a vapor barrier, radon barrier and thermal break in addition to other benefits. The foundation is ICF foam block which is fully insulated at R-21.
Heating, Cooling, and Hot Water:
We installed a Climate Master Geothermal 4-ton heating and cooling system in our home which heats and cools our home from energy from the ground. It takes energy from the ground and converts in into heat or cooling. The excess energy goes into a hot water storage tank which preheats our hot water to around 90 degrees. We bring the temperature up the remaining degrees with an electric hot water heater. This efficient system keeps even temperatures consistently in the house, and is due to the solar energy, has no energy cost associated to operate.
The ventilation system is a NU-Air Heat Recovery (HRV) system. This takes the exhaust air from the bathrooms, runs it through the HRV system, takes the energy from air, brings fresh air in and heats or cools the air so you do not lose the energy. The second part of the system is controlled by a CO2 censor which when the carbon dioxide level in the house gets above a certain point, it turns on and brings the carbon dioxide down in the house.
We put a 200-amp panel in our home. All lighting is LED. We used all energy star appliances. All closets have motion sensor lights. All our power comes from our Solar Photovoltaics.
Our zero energy house is powered by our Solar Photovoltaics. Our solar powers all of our electricity, including our appliances, our heating and cooling system and our well. We have 92 panels facing south capturing the sun’s energy. The geothermal system has 2 wells which takes from the ground and heats and cools our house.
Resources Sustainability Features:
Both of our renewable energy systems, geothermal and solar, are lifetime systems. The sun’s rays and temperature of the earth are sustainable forms of energy.
