WaterFurnace International, Inc., a manufacturer of geothermal and water-source heat pumps, just launched what the company is calling the “world’s most energy-efficient heat pump,” according to a press release. The 7 Series 700A11, pictured, is the first variable capacity unit available for homeowners and boasts a 41 energy efficiency ratio and 5.3 coefficient of performance. The 7 Series exceeds Energy Star requirements and qualifies for a 30% federal tax credit, said WaterFurnace. The heating and cooling system also comes with a laundry list of other design features: integration with automation and energy monitoring systems, online remote monitoring and control, quiet performance with a lower compressor speed, advanced hot water generation, and a port for service and diagnostics that doesn’t require opening the unit. 700A11 uses a soft-start variable capacity compressor, variable speed ECM blower, and variable speed loop pump to scale output as needed.
When Hulger launched a designer CFL called the Plumen, most of the design world went crazy for the product. So perhaps it will be with the new Nature LED bulb by JUSTLED. The bulb was on display at Dwell on Design, to the excitement of certain design blogs, and presents what could be the best way to go naked (or exposed) with a LED light bulb.
Since I last shared photos of the Dow POWERHOUSE Solar Shingle, this line of business has picked up. In October 2011, the Solar Shingle launched in Colorado, and Dow expanded the launch to Texas and California in April 2012. As part of the launch, this commercial — lazy roof — aired recently to show these markets how Dow is helping to reinvent the roof so that it not only provides shelter but power, too.
California-based Insteon just announced the new Insteon LED Bulb 8 Watt, which is the first networked, remotely controlled, dimmable LED light bulb in the world, according to the company. The bulb sells online for $29.99 and is designed to conserve a significant amount of energy over the standard 60-watt incandescent. Nonetheless, intelligence, not efficiency, is the name of the game with this controllable screw-type light bulb.
When I mentioned a project by students aiming to build the greenest house in Canada (by means of the Living Building Challenge and LEED Platinum certification), I noted that students planned to use “prefabricated straw bale walls.” It turns out they finished this portion of the project using BioSIPs from NatureBuilt Wall Systems in Ontario, Canada.
