All Our Homes Are Energy Efficient
All Our Homes Are Energy Efficient - Not Just An Option. Each home at Preferred Building Systems is designed and built with energy efficiency in mind. We work with the builder and their homeowner customer to create the perfect living environment. Attention to details like floorplan, component features, lighting and heating are part of the process that help build our custom modular homes.
Each of our modular homes is built energy efficient right here in the factory. We also practice green building where possible everyday. While other manufacturers may offer an energy efficient option or green building option, our homes come standard with these features. Preferred Building Systems has designed our custom homes with these money saving features already installed.
What is the HERS Index?
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. 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.
The HERS Index
The HERS Index is a scoring system established by the Residential Energy Services Network (RESNET) in which a home built to the specifications of the HERS Reference Home (based on the 2006 International Energy Conservation Code) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0. The lower a home's HERS Index, the more energy efficient it is in comparison to the HERS Reference Home.
Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home. Thus a home with a HERS Index of 85 is 15% more energy efficient than the HERS Reference Home and a home with a HERS Index of 80 is 20% more energy efficient. The last two homes tested from Prefrerred Building Systems were rated at 51 and 45 making them 49% more efficient and 55% more efficient than the HERS Reference Home.
