is contemporary thermal, moisture, and indoor air quality protection for buildings. For those interested in better building or better living in the Built Environment, this site will provide some fundamental and practical information to help. There are some common threads between weatherization and green building, historic preservation, super insulation, vapor barriers, environmental conservation, sustainability, insulation, air sealing, and energy conservation. We will talk about many pieces of a house: attics, basements, crawl spaces, walls, windows, roofing, siding, insulation, venting, furnaces, and ductwork. You may learn some things about ventilation, heat loss, solar gain, R-value, enthalpy, diffusion, psychrometry, and pressure diagnostics. But weatherization is primarily about making old houses and new buildings better serve the people who occupy them. Please keep that in mind. Weatherization will always be focused directly on the human element of residential construction.    My name is Fred and I will be your weatherization host. Houses and particularly old ones are interesting to me and my living is derived from making them more habitable. That is to say, safer, healthier, more durable, comfortable, economical, and beautiful. In fact, if we get the first five priorities right, the building automatically becomes more beautiful to me. I can't take credit for inventing or discovering any of this technology, but I will take responsibility for interpreting other people's ideas and writing and drawing all the things you see here. Part of that responsibility is to inform you that the union between each building and occupant is unique. Unless we study you and your home, we cannot speak with authority about the way your home works. Weatherization can be applied to dramatically change the way your home and you behave-for better or worse. As a condition for entering this site, you must agree never to blame me for destroying part of your house or all of it, killing anyone or making them sick, even your entire family, or blowing something up including the whole neighborhood. That's a strongly worded statement I ask you to take seriously. If you can't go along with it, we can still be friends, but you must here. If you can accept the generic nature of this information, the concept that a little mistake can have vital consequences, and the responsibility for any modifications made to your home, I invite you to enter and enjoy weatherization.
