T
- pic s Disc usse d During Me e ting s
- Reviewed items from baseline study shown to need more support
- Discussed construction methods that will allow better code compliance
(proper insulation installation, improved air sealing)
- Most builders and code officials agree that there has been a steady
compliance improvement over the course of the study
- Working together; the energy code requires significant crossover
between construction trades – the work of one trade substantially impacts another trade’s work
Circ uit Ride r Pro g ra m
Statewide Observations
- Several building departments have added additional
inspections to assure better compliance with the energy code.
- During the last year, site visits have shown an improvement
in energy framing techniques and insulation installation quality.
- Methods for installing slab edge insulation continues to pose
challenges
- Envelope tightness of less than 5 ACH cannot be consistently
identified by the visual inspection option
- There appears to be a better awareness of the energy code
requirements statewide

Kentucky Code Requirements
ERI Compliance
Using the Data
- The following slides can help us determine how homes are
currently being built and how they can meet the ERI compliance pathway in the IECC. – Important to note: the following ratings would likely see a 2-3 point increase in HERS index when rated in 2015 IECC compliance software.
- We will gain an understanding of which primary energy code
components have a big impact on HERS scores in Kentucky.
