H.E.R.S. Ratings / Mechanical Design
Builders-In today’s tough housing market, it is imperative to set yourself apart from the competition. H.E.R.S ratings will help do that by showing your potential customers your commitment to building a quality, energy efficient home. Builders who build green report having fewer call backs and higher customer satisfaction.
Walker Energy Services provides certified H.E.R.S ratings as well as mechanical design in accordance with Manual J, S,D and T by a licensed mechanical engineer. Both of these services are necessary to receive tax credits in the BGNM as well as LEED for homes programs.

What is a H.E.R.S. Rating? (From EnergyStar)
A home energy rating involves an analysis of a home’s construction plans and onsite inspections. Based on the home’s plans, the Home Energy Rater uses an energy efficiency software package to perform an energy analysis of the home’s design. This analysis yields a projected, pre-construction HERS Index. Upon completion of the plan review, the rater will work with the builder to identify the energy efficiency improvements needed to ensure the house will meet any necessary performance guidelines. The rater then conducts onsite inspections, typically including a blower door test (to test the leakiness of the house) and a duct test (to test the leakiness of the ducts). Results of these tests, along with inputs derived from the plan review, are used to generate the HERS Index score for the home.

Take advantage of generous tax credits by having your home certified under LEED for homes or the Build Green New Mexico programs.
