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.
