| Zero energy home in Truro, Massachusetts  ZeroEnergy Design, an architectural design and mechanical engineering firm, will be showcasing their newly completed net zero energy home located in Truro, Massachusetts, as part of both the 2008 Green Buildings Open House held annually by the Northeast Sustainable Energy Association (NESEA) and the National Solar Energy Tour held annually by the American Solar Energy Association (ASEA) as sponsored by the US Department Of Energy (DOE). The modern Cape Cod residence utilizes a combination of attributes to achieve net zero energy performance. First, energy requirements of the home are reduced by passive means, including attributes like staggered stud walls with foam insulation. Then the active systems throughout the house are selected for energy efficiency, such as the geothermal system which provides all of the heating and cooling. Lastly, renewable energy systems are sized to off-set the annual energy consumption as predicted by detailed energy modeling software. The end result is a grid tied home that utilizes net metering to spin its electric meter backwards and produces as much energy from renewable sources as it consumes. write your comments about the article :: © 2008 Construction News :: home page |
