Insulating a Slab-On-Grade in Hotlanta

Insulating a Slab-On-Grade in Hotlanta

Why in the world are we insulating a slab-on-grade in Hotlanta?

What needs to be done to get builders to follow Code for duct and envelope leakage?

“If your new home was not built properly to Code, you might pay $50,000 over the life of your home in extra energy bills. You may have health and structural problems caused by hidden hidden problems and improper inspections by Code officials.  At no cost to you, let us have your home checked to see if you are one of 1000s in Texas (name your State) where Codes are ignored.”

In Australia, homeowners are starting class actions against their builders for the same type of poor workmanship…

It was my first weatherization conference since becoming the editor of Home Energy. I remember sitting in the crowd listening to the opening speaker and being very inspired. We’re soldiers, I thought. Some of us are on the front lines—the weatherization workers—and some of us, like the staff at Home Energy, offer support from the safety of our offices in Berkeley. We are fighting for our nation’s energy security, and for the health of children and adults, and for the survival…
