The Three Laws of Home Performance Contractor
A performance contractor must do no harm through action or in action.
A performance contractor must follow the principles of building science unless they are in conflict with the first law

Building Science is not really science; it is more of a concept. While the concepts were developed by scientists the system itself is not really hard science. The concepts are generally employed by building analysts and construction professionals. While I consider myself a student of building science I do not consider myself a building scientist. I am simply a tradesman with special training. While some in the field might have different opinions about their role in this industry I am…Continue
I have a theory for what the N stands for in the N factor but really no clue. I understand what the n factor intends to do and how to use it but fail to understand how it applies in the real world and in particular to San Diego.
The N factor is a correction number that smooths the data for blower door numbers in multiple climate zones of homes of different size and height and brings the homes into a level playing field. We then can use this number…

Mechanical ventilation of your home is a good idea. That means a fan running 24 hours a day 365 days a year. It provides a means of reducing indoor air pollutants and improving IAQ. It’s good for you and your whole family. We have a cute saying “dilution is the solution to indoor air pollution”
But aren’t you supposed to show me ways to save money and use less electricity? I don’t get it
So, I was getting ready for my morning bike ride to the coast and decided I needed some calories. Part of my choice was some tortillas. I placed them in the toaster oven and went about my morning. This included drinking my morning coffee and checking my email.
Mmm what is that smell? I had inadvertently put the…Continue
Why was the plug pulled on Google PowerMeter?
Google’s philanthropic branch launched Google PowerMeter in February 2009. Its goal was to put the power of seeing electricity usage into the hands of the consumer. The idea was born of a study that showed that those that had access to daily energy data reduced usage by 10…
In these tough economic times everybody is looking to save where they can. In our quest to reduce our costs often times we decide to do nothing at all. It seems like sound economic policy because doing nothing cost nothing right….…Continue
CHEERS and The CEC
While I feel this will fall on deaf ears I felt it worth a try. I am (or was) a HERS Rater here in California. The CEC and CHEERS have “locked” many of us raters out of conducting business here in California. I have personally passed on jobs due to this squabble.
This lockout began in early October. It was thought that this would be resolved quickly. After a five month moratorium this obviously is not the case. As far as I know the problem is data…Continue
From my experience in the field I would say that code is the most overused misunderstood word. Early in my construction career I heard this word thrown around. It was and is referenced often with true meaning and good advice.
However it has also been used as a conversation ending to a dispute from the Ivory Tower “Thou shalt not doubt in me for I am the reference of thy Code and cannot be denied”. It is from these sources that I have issue. I have found that often times…Continue
As I sit here typing I am for the in a long time optimistic about our industry. The crash and burn of PACE and subsequently Homestar left many of us wondering if our industry would ever make it to prime time.
I have new found optimism. I am actually excited. In the last month I have seen the following.
Vice President Biden and the news conference regarding Home Score. Agree with it or not it got press. It also…Continue
