  • Use the Energy Star Building Checklist to cut down on winter heating costs.

  • Use the Energy Star Building Checklist to cut down on summer cooling costs.


  • Block direct sunlight shining through windows in the summer.

  • Let the sun in during the day in the winter, but cover the windows at night.

  • Keep external doors closed.

  • Use fans to help delay or reduce the need for air-conditioning in the summer.
