HERS rating and new Energy Codes
I have attended several new building code seminars here in Massachusetts that discuss the implications of the 2009 IECC Code as part of the 2008 Green Communities Act. In addition, this act allows municipalities the option of setting above code energy efficiency requirements for commercial and residential projects. Labeled the ‘Stretch Code’ and backed by $10M in funding, this code is noted as a practical way to demonstrate life-cycle energy efficiency.
The Stretch Code employs the Home Energy Rating System (HERS) with thresholds related to home sizes. New homes and additions will require blower door tests and several inspections by a HERS rater.
Now to my question. Are other states doing the same? Does anyone have any experience with HERS raters or training? The cost of rating a new home under the Stretch Code was said to be anywhere from $500 to $1,500, which would be offset by energy efficiency rebates.
