System to keep roof green
The Advanced Vegetative Roof System is a water-efficient green-roof system that incorporates Zeba-branded moisture-release technology for faster, fuller vegetation establishment and lower maintenance costs. Zeba’s cornstarch-based granules work like a sponge, holding and releasing water as needed and reducing the need for irrigation systems. The system weighs 15 lbs. per square foot when fully saturated. Columbia Green Technologies, Wilsonville, Ore. www.columbiagreenroof.com

Cooler PV system
The SolarWall photovoltaic/thermal system includes PV panels placed over SolarWall transpired collector panels that balance the air flow behind each PV module. In addition to converting sunlight into electricity, the system collects the residual heat energy and delivers both heat and electricity in usable form. The manufacturer claims the system can raise total solar efficiency to 50 percent and reduce payback periods by as much as half. Conserval Systems, Buffalo, N.Y. www.pvthermal.com

Atypical green washing
Bosch has added an EcoWash option to its latest collection of Energy Star–qualified Nexxt washers. Introduced at last month’s Builders’ Show, the EcoWash option will be added to other Bosch products in the near future. A single push of the “green” button optimizes heating cycles for greater efficiency, without affecting cleaning results. All Nexxt washers exceed the strict 2007 federal regulatory standards for energy. Bosch, Huntington Beach, Calif. www.boschappliances.com.
