SEEC LLC and Northwest Energy Efficiency Alliance (NEEA) today announced the launch of a cost data addendum for high performance homes as supporting documentation to the Uniform Residential Appraisal Report. The addendum responds to appraisers’ requests for credible incremental cost data for homes in their markets that incorporate high performance measures.

“It’s great news to see the appraisal and construction industries collaborating to help reduce appraisal hurdles for high performing, energy-efficient buildings,” said Scott Bergford, CGB, CAPS, owner of Scott Homes. “I am very grateful for this proposal to help support appraisals of high performing homes. We welcome the opportunity to partner in this effort and plan to fill out the evaluation report for each of our homes.”

Builders who drop out of home certification programs or choose not to build more sustainably commonly cite their inability to recoup the cost of incorporating green and advanced building practices. The addendum would provide real incremental cost data that an appraiser could use to support an adjustment for a home with energy-efficiency and green improvements.

“We're continuing to raise the bar and redefine energy-efficiency in new construction,” said Neil Grigsby, initiative manager, NEEA. “To keep builders on board, and in business, they need to be able to recoup the cost of making these improvements. We're excited to be a part of this first step and are committed to educating the appraisal community so that they can make more informed decisions.”

Michael Brunson, the vice president of the National Association of Appraisers (NAA), introduced a draft version of the cost data addendum to a group of stakeholders at the annual High Performance Home and Building Summit in August. Hailing the addendum as a step in the right direction, Brunson said that the addendum, if used properly, could lead to significant changes in green valuation. The Executive Board of the NAA endorsed the form, stating: “The NAA supports, in principle, NEEA’s new Cost Data Addendum for high performance homes as a significant step forward in providing data to residential appraisers about local incremental costs to install energy-efficiency and green features.”

While the cost of green building improvements rarely if ever equates to their market value, appraisers have lacked reliable data to support builders’ claims of higher property worth based solely on the cost of the energy-efficiency and sustainability measures employed. The cost data addendum, which is completed by builders, informs appraisers of improvements that elevate the homes’ performance beyond state and local codes. It also provides the incremental cost of the improvements and the Gross Living Area (GLA). With this information, appraisers could calculate the $Energy or Green Improvement per GLA and apply an offset adjustment toward comparable homes without these improvements provided they can identify a market reaction

To help familiarize high performance homebuilders with the cost data addendum, SEEC is conducting an outreach initiative targeting green certification programs in Washington, Oregon, Idaho and Montana.
