Priority Energy has been providing Blower Door tests and Duct Leak tests for the Village of Arlington Heights in Cook County, IL since the adoption of the IECC 2015 code. Builders and contractors in the village and surrounding areas have been relying on Priority Energy’s code compliance expertise for their timely and accurate testing and verification reports required by the village to obtain their Certificate of Occupancy.
Builders were a bit resistant to the mandated air tightness testing in the beginning, and air leakage was a little higher than allowed, but builders have worked with Priority Energy to tighten their homes and most are now able to confidently meet the required envelope tightness level. Many of Arlington Heights’ builders and HVAC contractors have also chosen to work with Priority Energy for the required Manual J, D, S calculations in order to meet the village’s requirement for building permits. Additional home performance and indoor air quality services are also becoming important to Arlington Heights’ builders and homeowners, alike.
The average blower door leakage for an Arlington Heights home is just over 3.8 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 Arlington Heights’ tightest home! Currently that honor belongs to North Mark Construction with a result of 2.6 ACH50
