Putney School, a prep boarding school for grades 9-12, needed a field house and retained Maclay Architects to design a green one. Literally. The ~$5 million green building is one of only a few net-zero energy buildings of its kind. It's also a contender for LEED Platinum certification and boasts a number of impressive green elements.
Recently, we had to opportunity to talk with Don Ferrier about the progress of a home called the Zero Energy Casita. Ferrier, president of Ferrier Custom Homes, started building earth-sheltered homes 25 years ago and has the distinct accomplishment of building the first LEED Platinum home in Texas. In this net zero energy beauty, Ferrier is building a home that generates as much energy in the course of a year as it consumes.
NanaWall Systems provides a sleek, folding, glass wall system that's seen in a lot of green homes that we mention (for example, see this Sunset Breezehouse). A homeowner may purchase a NanaWall for any number of reasons, whether to blur indoor and outdoor spaces, provide views, or draw natural light into interior spaces. Now, though, all this can be done with greater efficiency using NanaWall's new SL70 with triple glazing system.
A new company, Wattvision, is rolling out a beta version of an energy monitoring system, and it seems promising. The company is selling the Wattvision Sensor for $199 (currently only $149 with the code “wvbetablog“), which can be applied to compatible digital meters. With an online account at Wattvision and the sensor installed, you can start monitoring electricity usage online, on your phone, or through email reports.
As first reported by the New York Times recently, a new life cycle assessment of illuminants conducted by Osram, a German lighting company, provides support for the belief that LEDs are more efficient than incandescent bulbs. In fact, over the entire life of the bulb, from manufacturing to recycling, incandescent bulbs use approximately five times more energy than compact fluorescents and LED lamps.
