Web zero dwelling design from Suntuity will use twin PV/thermal solar panels
New JerseyBuilding contractors based on Suntuity Solar and Suntuity Home have begun building a unique LEED Platinum certified home, the first of many planned under the Suntuity Home branded Net Zero. The 100% solar powered structure will be the first self-sufficient net zero energy project for residential buildings in Zentral New Jersey with inexpensive and environmentally friendly BuildBlock ICF (Insulating Concrete Forms).
After completion of the construction work, 90 DualSun SPRING solar modules will be housed on the roof of the ENERGY STARirated house on a metal roof with Englert standing seam, 98% energy-efficient LED lighting, a 93 kW solar thermal heating system and 8 Tesla Powerwall batteries for electricity storage . In addition, a 1,800 square foot rain catchment area will be installed on the roof to save and recycle up to 40,000 gallons of water per year.
A geothermal heating system and hybrid heat pumps will be used for secondary and tertiary heating add-ons, and a 29,000-gallon infinity edge pool will serve as an additional hot water storage location in the colder months. The house’s insulated driveway, which is also to be built with ICF, will contain an ice melting system to counteract the icy weather conditions. Other leading brands used for this project include a mortar-free STONE facade from CertainTeed to prevent moisture-related problems, a warmboard radiant heating system, 3-pane PlyGem windows with low emissivity (Low-E) and a span of 36 foot hingeless panoramic doors with PVC and aluminum for improved thermal conditions and structural strength.
“We are excited to announce this unique pilot,” said Dan Javan, President and CEO of Suntuity. “It is the first of many net zero homes that we will build to provide homeowners and business owners with a sustainable, affordable and ideally carbon-free future that will have a positive impact on generations to come. We have done our best to work with a qualified team of professionals to bring such green structures to the market. “
The DualSun SPRING solar modules are hybrid PV and solar thermal devices. The water circulates inside the panel to optimize heat transfer in the PV cells. The front is a monocrystalline solar panel and the back supports the cooling system of the panel and uses the waste heat for solar hot water. The 90 315 W modules provide 28.35 kW of PV power.
While it has a plethora of benefits in reducing CO2 emissions, there are also significant savings that the homeowner will make over time – roughly $ 12,000 in annual energy savings or an estimated ~ $ 300,000 over 25 years. For additional savings, the standing seam metal roof with a low gloss non-reflective coating reduces energy costs by up to 50% and keeps the surface 60-70 ° F cooler than other roof options.
