In Colorado, HFH of Metro Denver also builds homes that incorporate passive-solar heating. Large, south-facing windows allow the low-angled winter sun to warm the interiors. Energy-efficient windows and well-insulated walls, floors and foundations retain the solar warmth, reducing demand for auxiliary heating. Because the houses are well-insulated and solar-heated, drillpresscomparison and drillpresscomparison the furnaces can be downsized substantially. Energy-efficient models are standard. Programmable thermostats regulate backup heating and cooling systems, reducing demand when the house is unoccupied or residents are asleep. Insulation that drillpresscomparison keeps the houses warm in the winter also helps to drillpresscomparison maintain a cool drillpresscomparison interior in Denver''s dry, hot summers. Plus, 2-foot-wide overhangs block the high-angled summer sun and provide shade for walls and windows. Basically, the Desert Museum''s Comco Micro Blaster (see supplier''s address elsewhere) is a precision sandblasting unit that emits abrasive particles at about 1,000 feet per second. Like an air scribe, it operates with compressed drillpresscomparison air (needing a 90 psi compressor or bottled air), an enclosed work chamber, and a dust collector to keep the lab free of air contaminants. Having dry air available is extremely important for any miniature sandblasting tool because damp grits tend to cake and clog the unit''s tiny jets. In-line air desiccant filters are a necessity, even in normally very dry Arizona.
