When contemplating improving our home’s performance it helps to have a general guideline or ordering of priorities when making the decisions that provide the most benefit for our investment.

Ductwork Testing
Apr 29
Based on field testing conducted statewide over a number of years, the California Energy Commission estimates the average duct leakage in California homes regardless of size and vintage to be 30%.
This translates into an increase in heating and cooling costs of approximately 20% for the average home.
The federal government’s stimulus package provides tax credits for an assortment of energy efficient home improvements. These range from building envelope improvements like air sealing and insulation through windows, heating and cooling equipment all the way to renewable energy projects like PV solar.
It’s a given that a green home should provide its occupants with superior indoor air quality, but the reality is all homes need good ventilation to exchange indoor air often containing moisture, odors and pollutants with fresh outdoor air. Thanks to environmental programs such as the Clean Air Act and other regulation our outdoor air [...]
What comes to mind when you think of energy efficiency?
It’s also important to keep in mind that energy efficiency isn’t about giving up things like comfort and convenience. It’s about getting more out of the resources we already use. We can enjoy a comfortable, well-lit home while being energy efficient and saving money too.
Simply put, yes it can. Traditionally, wood framed structures supplied needed ventilation and moisture control by infiltration through the building’s shell. This worked well except there was a trade off: excessive heat loss and cold drafts. Even with the addition of insulation, excessive air infiltration across fiberglass batts renders them ineffective at preventing heat loss. Fast forward a few years. In [...]
According to an article today in the Sacramento Business Journal Sacramento County has received $16.5 million in state funds to start their AB811 energy efficient loan program. If you haven’t read my previous posts on the subject, AB811 was a bill enacted last year to allow California cities and counties to set up special assessment districts [...]
