The Appraisal Journal published a study concluding that for every $1 decrease in annual energy costs, a homes value increase $20. Lets do the math. If you save $100 per month in energy costs, the savings equals $1200 per year. The homes value will increase $24,000. Typically energy cost increase 4% per year equalling another $960 per year in added value to the homes value. EEM’s will provide the following benefits:

You will need a HERS report.

A HERS report provides and evaluation of the homes energy efficiency. These are prepared by a trained Energy Rater. The homes insulation, appliance efficiencies, window energy ratings, utility rates all factor in the calculation of annual energy costs.

The report will include:

An overall rating index between 1 and 250 to show its efficiency relative to a reference home built to just meet the Title 24 Building Energy Efficiency Standards’ prescriptive requirements. The lower the number the better the homes energy efficiency performance.

Recommended cost-effective energy upgrades

Estimates of the cost, savings and useful life of the recommended upgrades.

An estimate of the annual energy cost before and after the upgrades.

The HERS rating typically is paid by the buyer, seller or real estate agent. The cost varies between $300 and $800. I recommend a HERS report for all sellers contemplating listing their property.
