However, appraisers are often not experienced in working with green buildings. When an appraiser is not versed in investigating the costs and benefits of green strategies, they might miss some of the benefits. To address this concern, the Energy Department and the Appraisal Foundation signed a Memorandum of Understanding to improve resources for appraisers who are involved with energy efficient buildings.
