The ECO-Build regulations were adopted to promote energy and material efficient building design and construction practices.  ECO-Build applies to all new construction, as well as additions/reconstruction over 50 percent of the existing floor area, and exterior energy uses such as snowmelt, spas, and pools.  The completed ECO-Build checklist must be submitted along with the subject building permit application.  Mobile home units that are approved by Colorado Department of Housing are exempt.

ECO-Build Land Use Regulations (Division 4-8 of the Eagle County Land Use Regulations) 

ECO-Build also considers exterior energy uses over a nominal amount as identified below.  Fees are based on average BTUs required for such amenities over a 20-year period in our climate.  Fees are exempted if renewable energy system(s) are installed onsite prior to completion of the amenity which generate the equivalent of 50 percent of the energy needed for the use.  Also, any rebates earned above may be credited accordingly.  System design and calculations required.

ECO-Build Offset Calculation Worksheet 

Exterior energy fees apply as follows:  
Snowmelt over 200 square feet:  $16 per square foot
Spa/hot tub over 64 square feet: $176 per square foot
Exterior pool:                            $136 per square foot

For example, if 500 square feet of snowmelt was proposed on a residential property, where 200 is exempt, then 300 x $16 per square foot = $4800
