My telephone doesn't ring that often. Face it, people just don't need the services of an expert on energy use of refrigerators every day or every week, for that matter. [continue reading]
Using pressure measurements to find and quantify air leakage in houses has been a hot topic over the past two years. Packed sessions at recent conferences are testimony to the intense interest these techniques are generating in the weatherization community. [continue reading]
