Why it matters: One of the biggest advantages of buying a newly built home is built-in energy efficiency. Today’s builders use advanced materials, systems, and standards designed to lower utility bills, reduce environmental impact, and improve comfort from day one.

But efficiency isn’t “set it and forget it.” A little routine maintenance helps protect your investment – and your monthly savings. Your new home likely starts off greener than resale homes – but upkeep keeps it that way.

What Makes New Homes More Energy Efficient

Many new homes are built to meet or exceed recognized efficiency standards, including:

  • ENERGY STAR®–certified appliances and HVAC systems

  • High-performance insulation and windows

  • Water-saving fixtures

  • HERS Index ratings that measure overall home efficiency

  • LEED-inspired construction practices in some communities

Smart Maintenance Tips for a Green Home

1. Stay on Top of HVAC Care

Your HVAC system does the heavy lifting for comfort – and energy use.

  • Schedule professional tune-ups once or twice a year.

  • Replace or clean air filters regularly (monthly or quarterly).

  • Ask your utility provider about rebates for maintenance.

2. Seal Air Leaks Early

Even new homes experience expansion and contraction as seasons change.

  • Check windows and doors for drafts.

  • Reseal caulking and weatherstripping as needed.

  • Make leak checks part of a seasonal routine.

3. Use Landscaping to Your Advantage

Your yard can help – or hurt – your home’s efficiency. Smart landscaping can significantly reduce cooling costs over time.

  • Plant deciduous trees on the south and west sides for summer shade

  • Choose native plants and grasses

  • Limit hardscaping that traps heat

  • Use efficient irrigation systems with moisture sensors

4. Let Smart Home Tech Do the Work

Many new homes come pre-wired or ready for smart devices. The results are energy savings without daily effort.

  • Smart thermostats adjust temps when you’re away

  • Smart lighting turns off unused lights automatically

  • Smart plugs reduce “phantom energy” use

5. Request Energy Reports or Audits

Your utility company may offer free or low-cost energy reports.

  • Track which systems use the most energy

  • Identify unusual usage spikes

  • Get personalized tips to save more

Everyday Green Habits That Add Up

Small changes still matter:

  • Unplug electronics or use power strips

  • Adjust thermostats slightly with the seasons

  • Turn off lights in empty rooms

  • Wash full loads and use cold settings

  • Clean low-flow fixtures to keep them working properly

  • Explore renewable energy options through your utility

The bottom line: Your new home was designed to be energy efficient – but smart maintenance keeps it performing at its best. Protect your home, lower your bills, and keep your investment green for years to come.
