Home performance, long seen as a tool for reducing greenhouse gas emissions, can also help individuals and communities adapt to climate change. To be effective in this role, the home performance industry must itself learn ...
All houses and apartments need an efficient way to exhaust stale, moist indoor air and introduce outdoor air. [continue reading]
Moisture problems occur in buildings throughout North America, in almost every climate. The most common symptoms are mold, mildew, and condensation, and these can impair the health of the occupants, cause discomfort, and decrease the life of the structure. [continue reading]
