New homes already save big on energy. ENERGY STAR homes bring 20% more savings on utility bills while ENERGY STAR appliances bring $450 of energy savings while LED lighting can save you over $200 annually. Altogether, new homeowners are sitting pretty when it comes to energy savings. Why not consider making your home more energy efficient?

Why it matters: Lower bills, a smaller carbon footprint, and higher resale value. Green homes can sell for up to 8% more.

Use the Land to Your Advantage

Smart landscaping can pay for itself in energy savings within eight years.

  • Cool the home: Plant deciduous trees on the south side for shade and airflow. Shading can reduce cooling costs by nearly 50%.

  • Add insulation: Place shrubs and vines next to walls for pockets of air insulation.

  • Block wind: Dense plantings of evergreens on the windward side of your home will reduce heating costs and wind chill.

  • Trap snow: Use low shrubs to keep snow away from the house.

Insulate the Smart Way

Insulation is one of the most cost-effective upgrades. It cuts energy use and reduces reliance on heating and cooling.

Key areas to insulate:
  • Attics, ceilings, and walls especially exterior walls

  • Floors above cold spaces and over garages

  • Foundations, crawl spaces, and basements

  • Band joists, knee walls, and cantilevered floors

  • Storm or replacement windows

Save Money When It Rains

Water costs rise every year. Rainwater collection systems help offset them.

How it works:
  • Capture rainwater from the roof

  • Transport it to storage

  • Store and distribute for indoor or outdoor use

Pro tip: Ask about gray water recycling for irrigation.

Ask the Right Questions

Your builder makes or breaks your home’s efficiency. Ask:

  • Why do you build green homes?

  • What certifications do you hold?

  • How many green homes have you built?

  • Can I see references and certifications?

  • Will the home be third-party certified?

  • Will it receive a HERS rating and appraisal addendum?

  • Can I view construction progress and meet the lead builder?

Bottom line: A well-planned energy-efficient home saves money, boosts comfort, and raises resale value. The payoff is financial, environmental, and long-term.
