It’s time to welcome a new green building protocol with the arrival of the Active House specification in the United States. The specification gets a big test with this home, called Active House USA, which will be the first Active House in the country when finished. It’s designed by Jeff Day & Associates and will be built by Hibbs Homes and Verdatek Solutions in St. Louis to test the new specification in a mixed climate. Here’s a little more about Active House and this 2,500 square foot home.
A company called Solyndra pioneered the solar tube but this new invention by UK-based Naked Energy may just take cylindrical solar to a whole new level. Called Virtu, the product includes an integrated photovoltaic cell in a vacuum tube to generate both electricity and warm water at the same time. The setup keeps the PV cool to optimize energy production and maximizes space with a combined PVT solution.
