Green Building Initiatives in Colorado


  • On July 15, 2005, Governor Owens signed Executive Order # D005 05 adopting LEED for Existing Buildings and incorporating LEED for New Construction practices for all state buildings. The order also creates a Colorado Greening Government Coordinating Council to develop and implement conservation policies.

    Executive Order:

  • Greening of State Government Buildings.  On May 8, 2006 - Senate Joint Resolution passed 06-032 concerning the greening of state government buildings.  The resolution supports use of LEED as design and construction guideline for all private and public facilities, promotes LEED Silver-level certification where cost effective over a twenty-year period, and supports the Executive Order # D005 05.




  •  Aspen, CO:  As of June 19th, 2002, all building permit applications must include a completed APEB Checklist. If the project includes a remodel and/or demolition/deconstruction, then the Deconstruction Plan form must be filled out in addition to the Checklist.  The APEB Program is and point based program designed to educate the public and the building trades about utilizing resources more efficiently. Flexibility is built into the program to accommodate a wide range of alternatives to create better buildings. The program addresses the reduction of construction waste, promoting recycled and renewable resources, energy efficiency, indoor air quality, renewable energy, water conservation, as well as efficient building techniques.

  • Eagle County, CO:  The  EAGLE COUNTY EFFICIENT BUILDING CODE (ECObuild) regulations became effective on September 27, 2006 and were adopted to promote energy and material efficient building design and construction practices.  ECObuild applies to all new residential R3 (single family, duplex, townhouse) construction per the currently adopted building code, as well as additions/reconstruction over 50% of the existing floor area, and exterior energy uses such as snowmelt, spas, and pools over sizes listed in the Eagle County Building Code.  The completed ECOBuild checklist must be submitted along with the subject building permit application.  Mobile home units that are approved by Colorado Department of Housing are exempt.

  •  Fort Collins, CO: On September 5, 2006, the city council passed Resolution 2006-096 establishing a goal that all new city-owned buildings over 5000 square feet achieve LEED Gold certification unless it is not technically or economically feasible to do so. If the incremental cost of achieving LEED Gold relative to LEED Silver has a payback period of greater than ten years for a particular building, then the City would opt to seek the LEED silver certification for that building.



  • Longmont, CO: In November 2006, the Master Board of Appeals approved a mandatory residential green building program based on the City of Boulder’s Green Points Building Program for homeowners to encourage sustainable and cost-effective residential building methods.  City Council will next be asked to vote this into law.

  • Telluride, CO: In March, 2005 the Town of Telluride adopted an ordinance requiring all residential new construction, additions and remodels to comply with green building regulations. The Green Building Code addresses many of the potentially harmful effects associated with building. The code is broken down into four catagories: energy efficiency, indoor air quality, materials, and resource conservation. The Code does not apply to commercial construction at this time.
