Lawrence Berkeley National Lab (LBNL) scientists, led by Max Sherman and Iain Walker, are investigating whole-house ventilation options to support California’s Zero Net Energy Homes initiative. This research project is called Smart Ventilation for Advanced California Homes (SVACH). California’s energy-and-climate goal calls for all new residential buildings in California to
Sliding glass door heat flow A sliding glass door’s large expanse of glass transmits a lot heat out of the home in the winter and into the home in summer. This heat flow takes three forms: heat conducts directly through the glass in winter, solar heat transmits through the glass
Attic vents and attic venting are the most familiar and reliable roof venting option. That was the subject of part 1 of this post. But they may not work depending on the building’s design. Features like sloping ceilings and cathedrals may dictate an unvented attic. An unvented attic and insulated roof
Attic vents and roof venting serve a variety of purposes, depending on roof design and climate. These purposes include preventing ice damming, drying building materials, and controlling solar heat gain. In cold climates, we want to avoid ice damming by keeping the roof deck cold. In all climates, we want ventilation air
Spring has arrived and Summer is just around the corner. If your heating system is in need of major repair or replacement, this is the time for you to get that done. If your furnace vents into an unlined masonry chimney, then you should install a chimney liner. If your chimney
Window manufacturers offer a variety of window frames for the variety of different new and retrofit window installations. Choose the right window frame. In most types of window installation, exterior window trim is an unnecessary and expensive extra to be avoided. Nailing Fin Window Frames The most popular type of window
My complements to the European high-performance window manufacturers for providing built-in sills for their windows. I hope that North American high-performance window manufacturers soon provide built-in sills. The built-in sills, along with block-frame window installation, sure simplify installing high-performance windows in superinsulated walls. American builders have tried dozens of different
The only thing worse than discovering your home has been water damaged is realizing that the damage has increased exponentially through mold. In less than two days, mold can begin to form in the recesses of your house after even minor water damage. Preventing Mold After Water Damage requires that
The best time to make major energy retrofits (also called deep energy retrofits) is during a renovation. This is when you’re making major changes to the building, and probably getting a building permit. Ideally, the house will be vacant during this process. Here are 10 major energy retrofits that should be part of every home
Dry and Decontaminate Quickly Flood recovery begins with drying and decontaminating the home as quickly as possible after the flood recedes. Materials like carpet, sheetrock, ceiling tile, insulation, and fiberglass ducts are almost never salvageable because you can’t decontaminate them. Begin by removing these wet materials. If the flood submerged the interior, cut a horizontal
