A popular approach for a green home is called Passive House. It calls for designing a home with a very tight building envelope and very high levels of insulation to minimize the need for mechanical heating and cooling. An alternative...
Located on just more than three acres, Washington Village is a net-zero community in the heart of North Boulder, Colorado. One of the homes uses a very tightly sealed building envelope and a ground source heat pump to deliver net-zero performance. This case study looks at the systems used to make this such a high performance home.
Addison Homes of Greer, South Carolina, built the “Invision Zero South Carolina” home to prove to its market that a conventionally styled zero energy home that produces as much electricity as it consumes is not only possible, it’s practical.
Builder Dow Perry’s goal was to build a home that costs the same and looks the same as nearby homes in Prattville, Alabama, but far outperforms them. By all accounts, the high-performance custom spec home he built at the Pebble Creek development was successful.
Mantell-Hecathorn, a long-time ENERGY STAR builder, committed to building all of its homes to the requirements of the DOE Zero Energy Ready Home program in 2014 and has since certified five homes through the program, including this custom home in Cortez, Colorado.
Philgreen Construction is one of a team of partners including designers, utility engineers, and energy modelers assembled by owners, REVIVE Properties, LLC, with the goal of making REVIVE Fort Collins “the greenest development in Colorado.”
After suffering an injury in Afghanistan, veteran Leo Perez was unable to work fulltime and had few hopes of owning a home. But with the help of the non-profit community development corporation Green Extreme Homes, for-profit builder Carl Franklin Homes, and multiple volunteer groups, the Perez family now owns a completely refurbished vintage home.
Every year, visitors to the International Builders Show get to tour a cutting edge home. Last year featured the first one to be certified through the DOE Zero Energy Ready Home program and the first DOE Zero Energy Ready certified home constructed by Element Design Build.
What does a building scientist want in a house when he decides to build his own? “Of course it’s going to be a zero-energy house,” said Paul Torcellini, a principal engineer in the commercial buildings research department at the National...
The South Sarasota Habitat for Humanity affiliate has constructed 21 DOE Zero Energy Ready-labeled homes to date including one home, the Saragossa Innovation Home in Venice, Florida, that won a 2016 DOE Housing Innovation Award.
This living laboratory is a home performance triple-play: zero energy, zero water, and zero sewer. Solar panels produce more power than the highly efficient home uses in a year, while rain water provides all of the home’s water supply and waste water is disposed on site.
When a net-zero-energy home can be built at a cost on par with traditional construction, everyone wins. TC Legend Homes is helping to usher in a new era of green construction in which home owners don’t have to choose between cutting-edge efficiency and staying on budget.
Aebi’s five homes in the Green Acres development in the Village of New Paltz, New York, achieved Home Energy Rating System (HERS) scores of about 25 before adding solar photovoltaic panels, and net zero energy scores of -1 to -7 after adding PV.
One reason people choose to live in the EcoVillage co-housing community is the community’s commitment to sustainability. That commitment to sustainability, especially sustainable energy-efficient construction, is one reason why builder Kendall Carpenter of AquaZephyr, LLC, wanted to work on the co-communal housing project.
