--TimberSIL, the sodium-silicate-treated wood that is an alternative to conventional ACQ-, copper-azole-, and CCA-treated wood. The material is becoming available in other products, such as residential siding. As a decking product, it meets California's new requirements for fire resistance.
--Mini-split, air-source heat pumps. With the cost of photovoltaic modules dropping, the ability to create all-electric, net-zero-energy homes is much more feasible. But creating highly efficient building envelopes, it is often possible to power a house (heating, cooling, electric loads) solely with rooftop PV. The dramatic improvements in air-source heat pumps make heating and cooling these homes more feasible--at a lower cost than with ground-source heat pumps. Leading manufacturers include Mitsubishi, Daikin, Panasonic, and Fujitsu.
--The Philips Endura LED replacement for incandescent lamps. The Endura is one of a new generation of LEDs using remote phosphor technology that offers great performance and is helping usher in this new chapter in lighting.
