Why Building IQ?

To reach Aspen’s climate goal of zero greenhouse gas (GHG) emissions by 2050, we must address emissions from buildings, which account for 57% of the community’s greenhouse gas emissions. 

In response, on April 12, 2022, Aspen City Council passed Building IQ through Ordinance No. 05. to address emissions from existing buildings. Building IQ is a significant opportunity to tackle GHG emissions from the built environment.

Building IQ addresses emissions from existing buildings through a phased, two-part program: benchmarking and building performance standards (BPS). Learn about each phase below.  

  1. Phase 1: Benchmarking
  2. Phase 2: Building Performance Standards (BPS)

What is benchmarking?

  • The process of building owners tracking their building’s energy and water use over time.  
  • Compares their building’s energy and water use to similar buildings, allowing owners and occupants to understand their building’s performance and identify opportunities for improvement.  
  • The following building sizes and types are covered by the Building IQ ordinance:
