37 Parkside Avenue in Southampton, known as “HGA House” was awarded LEED platinum certification by U.S. Green Building Council (USGBC) for achievement in green homebuilding and design. The HGA House is owned by David and Saundra Dubin, who were devastated when their original home was destroyed by fire in late 2009. Today, they are thrilled that their home may be among the top largest green homes in the country.
The Dubins will have architects Ric Stott, Craig Lee and the Hamptons Green Alliance (HGA) to thank for their newly rebuilt and designed home, which has risen from the ashes to become a model of net zero energy, embodied carbon negative green building.
“In combination with architects Stott and Lee, we, at the Hamptons Green Alliance, are very proud to have been a part of such an inspiring project,” says Frank Dalene, who is the co-founder of the HGA and the president of Telemark. “Innovative green building is transforming the world for a better future and we are doing it one home at a time.” Telemark served as general contractor for the project.
“As a LEED-certified home, HGA House serves as a model of greener living for the entire community,” said Nate Kredich, Vice President of Residential Market Development for the USGBC. “The home sets the example that we can all live better by reducing our environmental footprint, cutting our utility bills, and coming home to a greener place to live. What sets HGA House apart is its size. The HGA House combines LEED Platinum, net zero energy, and embodied carbon negative building in a 4,800 square foot luxury home renovation. The home’s embodied carbon footprint was successfully measured by ICEMAN, which was developed by Frank Dalene to provide a market driven solution to the challenge of reducing carbon emissions. The HGA House earned a Phase I Embodied Carbon Negative certification which means the construction of the home reduced more carbon emissions than carbon emitted. Along with the Architects and Telemark, HGA assembled a team of green craftsmen and suppliers to develop a plan for the building of the HGA House.
Among the aspects of the HGA House Dalene discussed were:
• Passive features from the architect’s design such as increased soffits to maximize solar gain in winter and maximize shading in summer
• A south facing orientation
• High efficiency windows
• Spray foam insulation – low expansion foam around windows, doors
• HERS Rating 25 was achieved – tests check for air leakage in ducts and the house; all ductwork in conditioned space and sealed; all joints caulked to decrease air infiltration
• Low Flow fixtures and dual flush toilets
• A rainwater harvesting tank to collect rainwater from gutters for irrigation
• LED lighting using 85% less energy than conventional bulbs and designed to last for 50,000 hours
• Smart house technology including LED screens on first and second floor to monitor house readings; programmable systems that turn on and off should an alarm sound; all rooms pre-wired for future programming; home energy monitoring
• A high efficiency wood burning fireplace to provide clean and efficient burning to minimize heat loss – the fireplace produces 50,000 BUT/hr.
• Energy Star appliances and electrical systems
• Geothermal system – open loop, two stage, variable speed with all ductwork insulated and sealed
• Solar thin film on the south facing part of house
• Solar panels on the east and west facing roof
• Solar thermal – for summer mode to provide domestic hot water and heat dump for pool heat mixing with the return water from the pool; the winter mode also supplies domestic hot water with the excess hot water going through hot water heating coils to distribute heat through the ductwork to heat the house as a primary heat source.
New technologies were integrated into the house including:
• LED lighting – CREE LR-6 high hats using only 12.5 watts of input power to deliver 1000 lumens, the LR6-DR1000 has unmatched fixture efficacy of up to 84 lumens per watt. It consumes half the energy of a typical CFL down light while delivering the same light output.
• Micro inverters for solar thin film photovoltaic
• Building integrated photovoltaics
• Solar thermal winter mode heat dump
• Whole house monitoring system.
