K Homes sets the standard for building energy-efficient homes. We even surpass the stringent ENERGY STAR rating by as much as 46 percent!
The RESNET® HERS Index is the industry standard measure for home energy efficiency. The typical home built to code has a HERS Index of 100. ENERGY STAR homes save 15 percent more energy, achieving a HERS Index of 85 (the lower number means greater energy efficiency). Compare our Standard version of The Stephanie model (2,900 sq. ft.) against an average ENERGY STAR home of similar square footage and configuration:
Normalized, Modified End-Use Loads (MMBtu/year)
| ENERGY STAR | K Homes | |
| Standard Model (2900 sq. ft.) |
The Stephanie (2900 sq. ft.) | |
| Heating: | 71.6 | 45.4 |
| Cooling: | 26.5 | 16.1 |
| Water heating: | 11.8 | 11.6 |
| Lighting & Appliances: | 39.8 | 46.4 |
| Total: | 149.7 | 119.5 |
| HERS Index: | 85 | 68 |
In this case, our Standard Home uses 17 percent less energy than the standard ENERGY STAR home, and 32 percent less energy than a typical home—a savings of more than $900 a year!
For even greater savings, compare our Geo-Hybrid version of The Stephanie model (2,900 sq. ft.) against an average ENERGY STAR home of similar square footage and configuration:
Normalized, Modified End-Use Loads (MMBtu/year)
| ENERGY STAR | K Homes | |
| Standard Model | The Stephanie (Geo-Hybrid) | |
| Heating: | 71.6 | 17.3 |
| Cooling: | 26.5 | 8.2 |
| Water heating: | 11.8 | 4.8 |
| Lighting & Appliances: | 39.8 | 38.9 |
| Total: | 149.7 | 68.5 |
| HERS Index: | 85 | 39 |
Our Geo-Hybrid Home—with its super-insulated shell, solar hot water heater, and advanced hybrid geothermal heating and cooling system—uses 46 percent less energy than an ENERGY STAR home, and an enormous 61 percent less energy than a typical home!
The superior energy efficiency of a home from K homes translates into real dollars saved on energy costs. In fact, depending on the model, our Geo-Hybrid home can save you as much as $1,800 a year! And with energy costs continuing to rise sharply, our homes compound your savings year after year.
