Copeland Casati, founder of Green Cabin Kits and Green Modern Kits, is busy these days. When she's not working on her own passive solar casa ti, she's helping folks across the country with theirs. Casati also just unveiled a revamped and newly engineered Dogtrot Mod Kit House, which is an energy-efficient 1,500 square-foot home with a 500 square-foot screened porch in the middle.
Announcements from LightFair this week lit up the news world. Lighting Science Group introduced cheap 40-watt and 60-watt replacement Definity LEDs, while Philips unveiled a brighter, more expensive 60-watt replacement EnduraLED. Not content with sitting the sidelines, Osram Sylvania today announced a bright 60-watt replacement LED that outputs 810 lumens.
The energy monitoring space is crowded, but chances are, you've seen the EnergyHub here and there. Perhaps you're in one of three utility pilots testing the product, which was named a Best Invention by Time last year. With EnergyHub, consumers can link up a dashboard, thermostat, plugs, and strips to *both* monitor and control energy use from home, a mobile device, or the internet.
With Light Fair 2010 next week, there’s a lot of lighting innovation in the pipeline. Take for instance this news we received from the Lighting Science Group. They’ve developed new LED lighting — referred to as the Definity LED line — which they say is rigorously tested and relatively affordable. The lights contain no mercury and are recyclable, dimmable, and long-lasting.
Older homes frequently aren't very energy efficient because power used to be extremely cheap and building codes varied widely. In mild climates, that tended to happen even more. Our home in Oakland was built in 1948 and was far from energy efficient when we bought it: single-pane windows and doors, some of which didn't close well; original floor furnace; no insulation in the ceiling or walls; drafty fireplace.
