Energy Efficient Improvements

An energy-efficient property is one that uses resource-effective design, materials, building systems, and site orientation to conserve nonrenewable fuels.

Special energy-saving items must be recognized in the appraisal process and noted on the appraisal report form. For example, when completing the appraisal report (Form 1004), special energy-efficient items are to be addressed in the Improvements section in the Additional features field. The nature of these items and their contribution to value will vary throughout the country because of climactic conditions, differences in utility costs, and overall market reaction to the cost of the feature. Some examples of special energy-efficient features may include, but are not limited to, energy efficient ratings or certifications, programmable thermostats, solar photovoltaic systems, solar panels, low-e windows, insulated ducts, and tank-less water heaters.

Appraisers must compare energy-efficient features of the subject property to those of comparable properties in the Sales Comparison Approach adjustment grid. Appraisers may augment the Sales Comparison Approach in evaluating any impact (either positive or negative) to the value of energy efficiency improvements with either the income or cost approach; however, appraisers cannot adjust the value of the property

• on a mechanical dollar-for-dollar basis based on equipment and installation cost, or the discounted present value of expected cost savings of the equipment over the useful life of the equipment; or

• solely based on the cost or income approach. The appraiser must also analyze the market reaction to the energy efficient feature.

Solar panels that are leased from or owned by a third party under a power purchase agreement or other similar financing arrangement must be considered personal property and not be included in the appraised value of the property.
