Last year, more than 22 percent of all new homes received a HERS rating through RESNET's standards. Pearl has established its certification on the East Coast and in California, and recently expanded into Wisconsin, Michigan, and Arizona markets. By increasing the quantity and accessibility of information about efficient homes, the partnership will increase consumer interest in home certification, creating new opportunities for both organizations.

RESNET Home Energy Raters will soon have a new certification available from North American Technician Excellence (NATE).

The Residential Energy Services Network (RESNET) and the Blow in Blanket Contractors Association (BIBCA) are working together to make density kits readily available for raters to test loose-fill wall insulation installations.
