At this very moment, ElectraTherm is releasing details of the successful installation of its new product, a commercial waste heat generator called the Green Machine. ElectraTherm tested their first Green Machine at none other than my alma mater, Southern Methodist University, and the results exceeded initial expectations. Stated simply, the Green Machine makes electricity from residual industrial heat that usually just goes to waste. ElectraTherm’s new product employs minimal heat (200 degrees F liquid) to generate fuel-free, emissions-free electricity at $0.03 – $0.04 per kWh during a three-year payback period and at under $0.01 per kWh after that. SMU’s test of the 50 kW Green Machine reached output well beyond the 50 kW rating.
You’ve probably seen Big Ass Fans in the gym or in some larger space, and that’s because they’re huge and energy efficient. Just last week, Big Ass Fans launched their newest product called the Element Fan. Element uses the 10 airfoil and wiglet design to move air quietly and efficiently. According to BAF: "At standard speed in a room with 16 ft. high ceilings Element is able to create comfortable breezes over an area larger than a basketball court, all while requiring less than 100 watts to operate. That is considerably less energy than even the most efficient small ceiling fan in production today." I’ve been around these gargantuan fans and love them. Seriously, they cool down a large space like nothing I’ve ever seen. Plus, you can really get creative with the colors, so as far as large fans go, this is a dang good option to go with.
If you’re like me, you like to follow what others are doing to build modern, energy efficient homes. One such home I’ve been following is at Denver Modern. Angelo, a local Denver designer, and his family are building their home on a narrow lot and have been blogging the progress since September 2006. As you can tell from some of the images in this post, it’s cool pad with a small footprint. The Haida cedar siding is distinct and deep in character — a modern touch I really like. I can’t wait to see the interior take shape with all the materials they’ve been planning.
Proximity Hotel seems to have found a way to deliver a comfortable, luxury-type experience and still be one of the greenest hotels in the country. It was built to use roughly 36% less energy and 30% less water than a comparable hotel. Proximity Hotel also heats over half the building’s water with roughly 4,000 sf of solar thermal panels on the roof. In the video embedded below, Dennis Quaintance, Chief Design Officer of Proximity Hotel, mentions that the savings from the solar thermal investment is about $20k per year. He also talks about the hotel’s innovative elevator, which is the first Regenerative Drive Otis Gen2 elevator in North America — it captures energy while going down and uses it while going up.
