Building Energy-Efficient Homes

Dear Expert: My husband and I are looking into building an energy-efficient home. What are the most important aspects to keep in mind? Alex, Medina

A: Making sure the main structure of the house is built well — even before adding all the bells and whistles — is the first step to ensuring an energy efficient home. The most efficient homes are built with quality insulation, windows, and flashing, making them able to withstand climate extremes. A well-built home equipped with an energy-saving heating and cooling system and air-exchanger will be most efficient in the long run.
