A HERS score is a numerical rating of the energy efficiency of a home. The Home Energy Rating System (HERS) Index was developed by the Residential Energy Services Network (RESNET). It uses an independent third-party to rate residential buildings, and scores are calculated based on factors such as insulation levels, air leakage, window performance, and heating/cooling systems. A lower HERS score indicates greater efficiency—a typical new home has a score of 100; while a home with no energy upgrades would have a higher number. The lower the HERS index score, the more energy efficient your home will be, which means you can save money on utility bills. As your Texas local RESNET rater, we will be glad to provide information regarding your home’s energy performance.
HERS Index Score Rating Explained – How Can It Save You Money?
You can use energy-saving devices by installing a solar panel on a bathroom sink or by installing an air conditioner. HERS (home energy rating system) Scores are sometimes an initial stage for deciding on cost-effective solutions to a problem. During the buying and selling process your home might also have heard about HERS scores or HERS indices. Tell me a reason for scoring a certain score? Is there any room in the house that needs any of this? Do you have HERS scores in your home that you plan to buy or sell? How can HERS help you reduce your expenses? HERS is the Home Energy Rating Scheme. The RESNET Residential Energy Services Index calculates the home’s energy efficiency.
Tell me the meaning of HERS rating?
More households decide each day to invest to make more energy efficient homes. Lowering your homes energy consumption with this nationally recognized system will help saving energy and increasing the home energy efficiency. In fact, energy efficiency can reduce the cost of living in the future if homeowners make smart choices. All homeowners looking to reduce costs and improve comfort in their houses will start by evaluating its effectiveness. If you know how your home compares with a similar size, you’ll be able to assess its performance.
Positive Energy Home (-1 or lower)
A negative HERS rating is also commonly termed a potential energy home. A home with more energy efficiency than a net zero home produces more energy than it uses for maintenance. Typically a house requires 80% more electricity to be put into a grid than it does in a typical home. A HERS score of -10 means the home produces 10 percent more renewable electricity per kWh compared with a normal new house’s usage.
Standard Resale Home (130)
130 is typical of an average sale for an actual house. These ratings are generally very positive, but you could do some improvements if you wanted to increase efficiency here. Standard New Home Built to Code (100) A HERS rated 100 is the industry standard for a new home. However, the rating cannot be guaranteed by a green building standard but meets the standard energy codes. It’s not allowed by code to achieve optimum efficiency at a minimum.
Net Zero Energy Home (0)
Homes producing more energy than their use are called net zero energy home. This score earns 0. Typically only a handful of homeowners have earned these scores due to needing alternatives for power generation, such as wind or solar. For homeowners, with a goal of increasing a home’s energy efficiency, it can be very beneficial in reducing their carbon footprint as they save thousands.
Energy efficient home (85 or lower)
This HERS index score is considered energy efficient. If your score is higher, your energy savings will increase. Homes in these ranges may qualify for being eligible for Energy Star certification in a manner that meets the targets or meets other criteria.
Important issues (150+)
HERS scores 150 indicate homes are using 50 % more energy than a standard home built to code. Many older homes scoring above 150 or 200 might be very expensive to maintain and may cause less comfort or negatively affect the environment.
The HERS Index Baseline Score is 100
Remember, the most important factor is the lower HERS ratings and the higher energy performance the house can achieve. Using 150 HERS ratings, the house will use 56% less energy than a home built in the standard energy code. Almost all homes are above 100 in this Index. Some older homes can surpass scores of more than 100. New homes built with energy improvements will score a 100 on HERS Index.
What variables are considered in a HERS rating?
Our certified raters perform a thorough analysis of the energy use and renewable energy produced in your home. A number of factors are important in determining the energy efficiency of the home, including windows, doors, venting, and pipes, in addition to other exterior structures. All renewable energies are also envisaged: Solar power panels.
How can I improve my HERS score?
If a HERS certified rating of the home has been obtained from the owner of the home you are also notified about any changes to your rating. Raters usually provide costs-benefit analyses of a proposed upgrade to demonstrate the savings in the longer term from increasing efficiency.
For sellers
A high HERS score can be very attractive selling points to anyone selling their home. Outstanding energy performance and lowered HERS scores can also increase re-sell value. Research conducted with Energy Sage has shown improving insulation, system appliances, and window insulation may improve home appraisal. It helps reduce the footprint on the environment and makes for better financial statements.
For homebuyers
Learning the HERS rating of a new home early will help you plan utilities and provide you with the correct finances for the long term. Buying a house that has good HERS scores will save you thousands of dollars over time in utilities, repairs and upgrades.
What’s hurting my HERS score?
A major source of energy waste in homes is the leak of air in homes. A leak from the outside makes the HVAC systems work harder and reduces the efficiency. The constant operation of high power equipment can increase scores.
