Benefits of a rating...

The HOME ENERGY RATING SYSTEM (HERS) is a voluntary system. The system has benefits for all types of users.

The homeowner can make energy saving improvements and be rewarded for it. A more energy efficient home has a higher rating and also a higher monetary value.

Realtors and builders can identify and use energy saving features to sell the homes.

Banks and mortgage companies can accept higher qualifying ratios for buyers of higher rated homes. This is possible because the prospective buyer will have to spend less to operate the home and therefore will have more money to pay the mortgage. There are even special mortgages called ENERGY EFFICIENT MORTGAGES.

Home Energy Rating, How does it work? 

The HERS index compares a home to an identical size and shape home that meets the ENERGY CONSERVATION CODE. The reference home has a score of 100. For every 1% reduction in total energy consumption, the score is lowered by 1 point. The lowest score is 0 and is for a home that has a net energy consumption of zero.

The score takes into account the heating, cooling, water heating, lighting, appliances, and onsite energy production to come up with the total energy consumption.

A practical use of the HERS INDEX is to compare the scores of homes when you are looking to buy or rent. A smaller score means you will have to spend less to operate the home.

The score is a simple way of "looking under the hood" before you buy!
