Those searching for a new home have a great tool at their disposal called the Home Energy Rating Index, or HERS Index. The index is based on a process that
calculates the energy efficiency of a home. It allows you to compare the energy efficiency rating of a property you are interested in against a single control factor.
What Do You Need to Know About the HERS System?
Although the HERS Index may seem complicated at first glance, the fundamental ideas behind it are quite simple. Some of the things you should know include the following:
- The HERS Index is a composite score that takes into account the level of energy consumption from a number of sources. These include heating, cooling, water heating, lights, and certain types of appliances.
- Each change of one point in the HERS Index represents a climb or drop in the total energy efficiency of the home.
- Your HERS score should be low. A score of zero shows that the property has net-zero energy use. This means that the house produces exactly as much energy as it uses and nothing is wasted.
To calculate the ultimate HERS score of a home a number of factors are fed into the equation, including energy consumption, water heating, lights, and some types of appliances. These factors are then computed and compared against the score of the HERS control home. If the total score equals that of the HERS control home, it receives a score of zero. If it receives a score in the negative numbers, this means that the home is, more energy efficient than the HERS home.
How Can Knowing the HERS Score of a Home Help You?
Knowing the HERS score of a property will definitely help you to purchase a more energy efficient home. If your goal is to spend as little money as possible on heating, cooling, and other utilities, a lower HERS score will point you in the right direction.
