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

slide-17
SLIDE 17

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

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.
