The Alliance for Sustainable Colorado is a nonprofit organization started in 2004 to "advance sustainability through collaboration among nonprofits, business, government and education." The Alliance purchased a 100-year-old warehouse, previously renovated in the 1970s, in Denver's historic Lower Downtown; a major renovation to the building in 2006 created the Alliance Center. The building provides tenant space for 35 sustainably-focused nonprofits. The Alliance for Sustainable Colorado recently launched a project titled "Modeling a NetZero Future: Energy Efficiency in Existing Buildings". Several documents developed for the project were referenced in this report.
The Alliance Center performs very well in terms of actual energy use when compared with other buildings. The actual energy use of the building is currently 42 kBtu/sf/yr, which is 55% better than the average for U.S. office buildings. A number of features contribute to this low energy use:
Owner & Occupancy
Commissioning, Operations and maintenance, Insulation levels, HVAC, Lighting control and daylight harvesting, Efficient lighting, On-site renewable electricity, Daylighting
