What to Look for in an Energy-Efficient Home

July 16, 2026

Energy efficiency is an important consideration when buying a new home. The right features can help create a more comfortable living environment, reduce unnecessary energy use, and potentially lower monthly utility costs.

For buyers comparing energy efficient home builders, it helps to understand which features can make the biggest difference.

What Makes a New Home Energy Efficient?

An energy-efficient home is designed so its major systems work together effectively. Insulation, windows, heating and cooling equipment, appliances, and plumbing fixtures all contribute to the home’s overall performance.

Some important features to look for include:

  • Properly installed insulation and air sealing
  • Double-paned, insulated window
  • Energy-efficient heating and cooling systems
  • HVAC zoning that allows different areas of the home to be controlled separately
  • Energy-saving appliances, water heaters, and plumbing fixtures
  • LED lighting and programmable thermostats

These features can help reduce drafts, maintain more consistent indoor temperatures, and prevent heating and cooling systems from working harder than necessary.

The Benefits of Buying an Energy-Efficient New Home

One advantage of new construction is that energy-saving features can be incorporated into the home from the beginning. Improving an older home may require replacing windows, adding insulation, updating appliances, or installing a new HVAC system.

An energy-efficient new home may offer:

  • More consistent temperatures throughout the home
  • Greater indoor comfort during hot summers and cold winters
  • Reduced energy and water consumption
  • Potential savings on monthly utility bills
  • Less strain on heating and cooling equipment

Actual energy use and utility costs will vary based on the home, climate, household size, and homeowner habits.

Understanding Home Energy Ratings

Homebuyers may also hear about the Home Energy Rating System, commonly called the HERS Index. This rating is used to estimate and compare a home’s energy performance.

A standard reference home receives a HERS score of 100. Homes with lower scores are considered more energy efficient. When comparing new homes, buyers can ask whether the home has received an energy rating or inspection and what information will be available at closing.

Simple Ways to Save Energy at Home

Energy-efficient construction provides a strong foundation, but everyday habits also make a difference.

Homeowners can reduce energy use by adjusting thermostat settings when they are away, regularly replacing HVAC filters, using LED bulbs, running full dishwasher and laundry loads, and closing blinds during the hottest part of the day.

These small changes can help the home’s energy-saving systems perform as intended.
