Circ uit Ride r Pro g ra m T opic 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
