Home Energy Rating Standards, involve measures that cover the HVAC system and insulation in construction, it measures the homes energy efficiency and how compatible it is with recent regulations. A HERS rating can be either used for new or old constructed homes, this way home owners and buyers can both rate the energy efficiency of their current or potential homes to see what measures they can take in order to cut energy costs, and be more efficient. This rating is usually done through a certified HERS rater, who has the proper training and experience in the field. In order to get certified for HERS testing these raters must have demonstrated a passing grade in the Calcerts or Cheers rater exam.
HERS testing regulations were established for California homes in 1999, as a requirement of the California Energy commission to establish criteria for a home energy rating program that is statewide, and relates to residential homes. The purpose of HERS testing was to establish a set rating scale to be able to differ the energy efficiency levels of different California homes in order to make the investment in energy efficient measures a top priority.
These standards are created and regulated by the California Energy Commission. These standards give the procedures to testing measures, such as how proper duct testing should be done. They also define procedures for training and certifying HERS raters.
A Hers rating is a number that shows how energy efficient a home is. The HERS index is determined by comparing energy efficiency of a given house to that of one that is of the same dimensions and is built to HERS standards and has an index of a 100. An index of 0 during testing for a home makes the house to be considered a Zero Energy Home which means it is equipped with a great number of energy efficient renewable power generation sources, and has passed all the HERS testing methods, confirming that it meets all the energy output for that home.
To perform HERS testing on a new or old home in order to establish a rating many things about the home are considered. These tests consider insulation values of walls, heating, cooling and water systems. It also considers the lighting system, appliances, and duct leakage. Careful measures must be taken on all the factors that may cause a loss of energy in order to get the proper rating in the index. It is crucial to know exactly where your home stands in order to come up with a proper energy saving plan.
The benefits achieved through proper HERS testing are endless. By preserving energy and being more efficient you will cut costs from your bills and save money. It can also set you on the right track to setting up your home to be energy efficient. It is a great start to go green, and help the planet while saving money and living in a energy efficient home.
