City of Boulder, Commercial Energy Code Consultation

Improving Boulder Building Energy Efficiency

The objective of this project with the City of Boulder, Colorado was to determine the cost premium to a building owner for constructing a building that is 20 percent more energy efficient compared to the current standards of the 2012 International Energy Conservation Code (IECC). Within a tight timeline, Brendle Group and its partner, Colorado Code Consulting, conducted research and developed a methodology for evaluating energy savings and costs for a variety of code measures and scenarios. This development included facilitating an industry working group to establish cost parameters that informed recommendations. On the basis of this background effort, the team identified, analyzed, and prioritized measures to achieve the desired 20 percent energy efficiency improvements for a variety of building types. Analyses included energy modeling, engineering calculations, industry standards, and feedback from City staff.
