What do you get when you cross a deep energy retrofit with an 1880s Victorian-style home?
It is common practice in California to put ducts outside the conditioned space, in attics and crawlspaces. These duct systems are typically 50%-70% efficient due mostly to air leakage and heat transfer losses, while sealed conditioned-space duct installations have efficiencies over 90%.

Dense-pack cellulose insulation is a very useful and cost-effective technique for lowering both conductive and convective heat losses in a variety of housing types. [continue reading]
The same features that are often added to the top story of homes to give them distinctive architectural beauty can also make them rather beastly to heat or retrofit. [continue reading]
Icicles and ice dams form at the eaves of some roofs in cold regions. Water that ponds behind ice dams may leak into the building since most steep roofs are configured to shed water, not hold back standing water. [continue reading]
Architects have traditionally used light surface colors to cool off buildings in hot climates, but until recently there was little research on the measured cooling-energy savings of reflective roofs. [continue reading]
Skylights, like windows, are distinctive features of homes that greatly influence their aesthetics. [continue reading]
In the highly competitive home building industry, successful builders learn quickly that to stay in business they must keep construction costs down. Unfortunately, some builders cut costs by skimping on energy features. [continue reading]
