The Secret Math Behind RMI’s New Headquarters

The Rocky Mountain Institute (RMI) Innovation Center is going to be one for the record books.

Naturally ventilated and with a minimal mechanical system, this 15,600 ft2 commercial office in Basalt, Colorado, was tracking a miniscule energy use intensity (EUI) of 17.2 kBtu/ft2 during the harsh winter months after its initial occupancy in December 2015. It’s a beautiful and innovative space whose passive systems are doing almost all the heavy lifting. These technological feats will be talked about for decades to come.
