Working Together to Create Better Efficiency

Eagle County Helps Building Owners Meet State Standards

CORE and Eagle County have partnered to help large commercial and multifamily buildings cut carbon emissions and ensure sustainable, comfortable, and efficient spaces for all. By taking action today, we’re preserving Eagle County’s natural beauty and leading the way in environmental stewardship.

Work with CORE

Buildings account for nearly 50% of Eagle County’s greenhouse gas emissions, making energy efficiency a key strategy in its climate action plan. To achieve a 50% emissions reduction by 2030, we must improve building performance.

Improve Your Building Performance

To support property owners in meeting Colorado’s building performance regulations, Eagle County is stepping up to help. The State’s Building Performance Colorado program requires large commercial, multifamily, and public buildings to benchmark utility data and select a building performance compliance pathway by July 1, 2025. These steps will help us meet state goals to reduce large building emissions by 7% by 2026 and 20% by 2030 (compared to 2021 levels).

Funding, Resources & Expert Guidance Accessible to You

Eagle County is partnering with CORE to provide free, personalized support for select property owners and managers to meet these targets. The goal is to help buildings track energy use, improve efficiency, and meet both county and state compliance requirements.
