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 Oak Brook 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 qualityservices are also becoming important to Oak Brook builders and homeowners, alike.
