Priority Energy has been providing Blower Door tests and Duct Leak tests for Deerfield, IL since the adoption of the IECC 2015 code. Builders and contractors in Deerfield and the surrounding communities have been relying on Priority Energy’s code compliance expertise for timely and accurate testing and verification reports required by the Village of Deerfield to obtain their Certificate of Occupancy.
Builders were a bit resistant to the mandated air tightness testing when the new code was first adpted, and air leakage was a a bit higher than allowed, but Deerfield’s builders worked with Priority Energy to tighten their homes and most are now able to confidently meet the required envelope tightness. Many of Deerfield’s builders, architects and HVAC contractors have also chosen to work with Priority Energy for the required Manual J, D, S calculations they need in order to meet the village’s requirement for building permits. Home performance improvements and indoor air quality services have also become important to the villages builders and homeowners, alike.
The average blower door leakage for a home in Deerfield is just over 3.7 ACH50 , but please take a look at how the area’s test results have evolved over time, and as always we like to give credit where credit is due – we will be on the look out for Deerfield’s tightest home! Currently that honor belongs to a home that was spray foamed by EcoTec Insulation, coming in at 1.9 ACH50
