What Is Denver’s Green Roof Initiative?
The Denver Green Roof Initiative requires new buildings and existing buildings undergoing roof replacements in Denver to cover a percentage of a building into green space, solar panels, or a combination of the two. This law is designed for buildings over 25,000 sq. ft., that need permits after Jan. 1st, 2018.
In November 2017, voters passed the Denver Green Roof Initiative in order to reduce Denver’s Urban Heat Island. The Urban Heat Island effect (UHI) is when urban areas become hotter than the surrounding rural areas due to the large amount of impermeable surfaces, such as concrete parking lots and black rooftops.
Denver is the 3rd highest in UHI; meaning Denver is much hotter (about 23 degrees hotter) in summer than its surrounding rural areas. With only 50% of Denver homes having AC, hotter weather can result in heat-related illness or death.
What Should You Know About Denver’s Green Roof Initiative?
Initially, The Denver Green Roof Initiative was not well received in the development community, because of the cost and the additional hoops to jump through to build in Denver.
To mitigate this, a Green Roof Task Force Committee was formed with local stakeholders. After six months, they reached a consensus-- creating a Green Building Proposal for Denver’s City Council to vote on.
Denver’s City Council is in the process of voting on accepting the new Denver Green Building Initiative into law. The City is creating new rules, regulations, definitions, permitting forms and hiring additional City staff. The decision to finalize this proposal should occur in fall 2018.
