Project Dilemmas
We've seen a lot of communication breakdowns and simple misunderstanding of the HERS process as it relates to the NSHP, we've decided to compile some of the most common problems we see out in the field. These are real stories with the names omitted for confidentiality .
Case 1
The Title 24 calculations were changed after the original incentive application was submitted. The new changes were executed by someone that was not a CEPE. The changes took the project from 18% over Title 24 to 8% over.
Result
Energy calculations had to be performed 3 times. Extra trip and total of 4 hours to repair miscommunication to comply with NSHP requirements. Lengthy delay in $16,000 rebate. Added cost of additional HERS measures.
Case 2
Title 24 calculations called for QII. The solar contractor called us just before occupancy. We had to send the project back to the CEPE and incorporate other measures including blower door. The builder had to spend a lot of time making the home tighter delaying occupancy and making the solar contractor look very bad.
Result
CEPE re-calculations, builder man hours, HERS Rater time, substantial delay in $9,000 rebate, confidence in solar contractor penalty.
Case 3
Solar contractor calls us 6 months after home is occupied. HERS measures performed with occupants afoot resulting in twice the time to verify the home and exponentially raising our liability. Home owner not happy.
Result
We absorbed the extra time involved since the contractor, in spite of attending classes on NSHP field verification, did not know the process. Home owner missed out on energy efficiency opportunities and $500 rebate from PGE
Case 4
Builder and solar contractor unaware of PGE rebate for >35% over Title 24. CEPE unaware and uninvolved with home owner resulting in missing deadline for application.
Result
$2,000 lost incentive rebate.
