The Planet Traveler hostel is built on a streetcar line in a walkable district of Toronto, in a retrofit of an historic building with teensy hostel rooms, (dorms starting at C$30 per night) so it already is greener than just about any big new green hotel in the suburbs of Scottsdale.
Then the Gizmo Green kicks in.

The key move is the installation is a ground source heat pump system with eight loops 350 feet deep. But like most downtown properties, the building covered the entire lot, and the loops had to be drilled in the adjacent back lane, under public property. This just isn't done in Toronto, so Tom Rand had to spend months fighting through city hall to get approval of 14 different departments. According to the Globe and Mail, the City is now setting up a task force to "to streamline geothermal development in city-owned alleyways and parkland."
According to Energyboom, other strategies include the installation of Powerpipes to recapture the heat from showers, Solar thermal heaters on the roof for hot water, and a 4.7 kilowatt array of photovoltaics that also act as the awning over the patio. The electrical load for every single one of the LEDs that provide all of the lighting in the building totals 1,600 watts.
Tom Rand estimates that these moves will reduce energy consumption by 75%.
Tom hasn't even put a number to the embodied energy saved by repurposing an existing building, by doing a hostel where the square footage per person is so much lower than a conventional hotel, by building without parking and for a clientele that tends to walk or take the streetcar. Everyone loves the green gizmos, but those choices are just as important in the bigger picture of building green businesses and buildings.
