Energy Efficiency

untitled _ 02 - Web.jpg

Your new home will be energy efficient. 


It's easy to make a promise, but it's much harder to keep one. With every new Lillian Custom Home, we promise energy efficiency through lower utility bills. To make the commitment of energy efficiency tangible, we have partnered with Efficiency Promise to provide a guarantee on the energy used to heat and cool your home. If the combined actual usage of electricity or natural gas exceeds the amount guaranteed on your home, Efficiency Promise will pay 100% of the difference for the first 2 years after your home is complete!


Efficiency Promise guarantees your heating & cooling bill for the first 2 years of residence.  




How does Efficiency Promise determine the amount of energy required to heat and cool my home?


The Home Energy Rating System (HERS) Index is the industry standard by which a home's energy efficiency is measured. Created by the Residential Energy Services Network (RESNET), the HERS Index is the nationally recognized system for inspecting and calculating a home's energy performance. With one number, homeowners and buyers can tell how energy efficient a home is. The lower the score, the better the energy performance of a home. 


You can see above that Lillian Custom Homes are well below the standard new home rating on the HERS index. For Lillian homeowners this means lower energy bills, less impact on the environment, higher resale value and much more.
