When buying or selling a home, energy efficiency is a hot topic—especially in Minnesota, where extreme winters and humid summers can impact utility bills. One of the biggest factors in a home’s energy performance is its windows. But how do you know if your windows are energy-efficient, and what should homeowners and buyers look for?
Signs Your Windows Are Energy Efficient
If you’re considering upgrading or evaluating a home’s efficiency, here are key factors to check:
✅ Double or Triple Pane Glass – Multi-pane windows are more efficient than single-pane because they trap insulating gas (like argon or krypton) between the panes.
✅ Low-E Coating – This invisible layer helps reflect heat inside during the winter and blocks excess heat in the summer, keeping temperatures more consistent.
✅ Energy Star Rating – Windows with the ENERGY STAR® certification meet strict efficiency guidelines and can help reduce heating and cooling costs.
✅ Proper Sealing & Weatherstripping – Even high-quality windows can leak air if they aren’t sealed correctly. Check for gaps, drafts, and old or worn-out weatherstripping.
✅ U-Factor & Solar Heat Gain Coefficient (SHGC) – The U-Factor measures how well a window insulates, while SHGC measures how much heat it lets in from sunlight. Lower numbers are better for both in extreme climates like Minnesota.
Benefits of Energy-Efficient Windows for Homeowners & Buyers
💰 Lower Energy Bills – Efficient windows can reduce heating and cooling costs by 10-25%, making them a great long-term investment.
🏡 Increased Home Value – Buyers are increasingly looking for energy-efficient features, making upgraded windows a great selling point.
🌱 Environmental Impact – Using less energy means lowering your carbon footprint, which benefits the environment while saving money.
🔇 Improved Comfort & Noise Reduction – Well-insulated windows keep cold drafts out, maintain indoor temperatures, and reduce outside noise—perfect for city homes or high-traffic areas.
Thinking About Buying or Selling? Consider Window Efficiency!
If you’re house hunting, check the age and condition of a home’s windows—replacing inefficient windows can be costly. If you’re selling, consider upgrades that improve energy efficiency to boost resale value and attract eco-conscious buyers.
