After kind of a slow start last fall, the SMUD Home performance program part of the Energy Upgrade California program has been going in full swing for a few months now. I thought it would be interesting to share some results of the program by profiling a recent project I completed in Fair Oaks. In [...]

This October we finally began work on our Multi-Family green retrofit project. If you haven’t read previous articles on it, this is a project we have spent nearly a year putting together and getting the go ahead from HUD. The project is on a 78 unit senior apartment complex constructed in the late 1970′s. The [...]
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. It’s important to look at the house as a system where each part interacts and ideally works together with the rest. If we ignore this interaction and focus our attention on single source solutions, at best we miss opportunities to leverage our decisions and in the worse case cause unintentionally negative results.
First lets look at some ways a remodel can affect your whole house. You might be planning to do a simple kitchen or bath remodel. You would never think that it could affect the other areas of the your home that aren’t included in the remodel scope of work. Many of the neighborhoods I [...]
In case any of you are wondering whatever happened to this project or if it ever started, I thought I’d give a quick update on where we are in the process. No, unfortunately we haven’t started construction on the project yet. Yes, we are still planning to get going as soon as HUD and the powers that [...]
Infrared Thermal Imaging
May 3
Originally developed by the U.S. military as an advanced weapon sighting technology FLIR or Forward Looking Infra Red thermal imagers were eventually adapted by firefighters to aid in identifying hidden fires in walls and looking for victims in low-visibility smoke environments. Unlike x-ray technology infrared does not see through a material but graphically measures subtle [...]
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 [...]
California First is a statewide program adopted earlier this year in Sacramento allowing property owners to participate in the state’s AB811 program, providing financing for energy efficiency and renewable energy upgrade to their properties. California First is an example of a Property Assessed Clean Energy or PACE program. Here are some of the basics of how [...]
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.
In the last post we examined tha actual efficiencies of tankless waterheaters apart from the industry claims. We discussed the high upfront cost against the actual savings in dollars. A couple of other issues to keep in mind if considering going tankless: “Cold Water Sandwich” Imagine a common situation we have all experienced. You turn [...]
Tankless or on-demand waterheaters have been enjoying a rising popularity for a number of years now. During my years of custom homebuilding they were considered a must have feature for a number of reasons. They are purported to save energy over a standard storage type waterheater because you aren’t paying for the standbuy losses of heating a tank [...]
2009 may well go down in the record books as one of the economically worst in recent memory. Venture capitol investing and IPOs fell to their lowest levels in over 10 years. Governments around the globe scrambled to implement stimulus programs to shore up their crumbling economies and try to create jobs to counter rising [...]
