New Jersey-based Englert, a company that specializes in metal roofing and gutter systems, recently earned a citation from Architect Magazine for their incredible Solar Sandwich roof system. On the surface, it looks like any other standing-seam metal roof with columns of thin-film photovoltaic solar. Yet below that, to capture the warmth generated from hot metal roofing, there’s a grid of pex-filled purlins with a water and glycol solution for a solar thermal system.
EnergyHub just announced the launch of an energy management system for consumers interested in monitoring, controlling, and reducing energy use. The system includes an in-home display, wireless thermostat, sockets, and strips, as well as iOS and Android apps for on-the-go control. Some purchasers will also be able to integrate the system with data from their smart meter if they have a compatible meter.
Boy do I feel great for grabbing a handful of 60-watt replacement LEDs for $40 a pop! Lighting Science Group and India-based Dixon Technologies today announced plans to launch the world’s first sub-$15 60-watt equivalent LED bulb. The bulb will be available in India by the end of this year and around the world sometime in 2012.
The biennial Solar Decathlon is coming up next month with teams preparing their solar-powered homes for West Potomac Park in Washington, D.C. The competition will showcase modern, energy-efficient homes from 19 teams from September 23 – October 2, 2011. We’ve taken a look at the architectural models for each home and continue our coverage this year with a look at the renderings. There’s some great work here. Any predictions? Which team will take it all?
Sunverge has released a new Solar Integration System (SIS) package containing an inverter and battery storage unit to complement the standard residential solar PV array. Brought to the market in February 2011, this new offering will give homeowners the opportunity to attain reliable net-zero energy status and eliminate reliance on the grid.
On average, about 18% of home energy consumption is for water heating, the second largest consumer behind space heating. The primary technology used to do this is the tank-type water heater (both gas- and electric-powered), but solar water heating can be a cost-effective way to generate hot water.
