Hello Ladies and Gentlemen,
I've been thinking about the topic of multifamily blower door tests for a while, and I want to get your opinion. This is an article that I wanted to publish in Home Energy Magazine but I thought it would be better to get up sooner. It's about energy code language regarding blower door testing. When I was at Steven Winter Associates, the NY State Codes Council asked for advice about blower door testing language, so that's where this originates. I hope you…Continue
The International Energy Conservation Code (IECC) constantly evolves to meet current energy efficiency needs. Over the years new requirements have been added to the IECC to make it stricter and increase overall energy efficiency of buildings. Some states are resistant to these changes, and some choose not to adopt an IECC at all. In fact, of the 50 states and the District of Columbia, 10 either haven’t adopted an IECC, or are operating under a code older than the 2006 IECC, according to the…Continue

“If your new home was not built properly to Code, you might pay $50,000 over the life of your home in extra energy bills. You may have health and structural problems caused by hidden hidden problems and improper inspections by Code officials. At no cost to you, let us have your home checked to see if you are one of 1000s in Texas (name your State) where Codes are ignored.”
In Australia, homeowners are starting class actions against their builders for the same type of poor workmanship…Continue
During the sales process, it is inevitable warranty periods will be raised. I remember raving about how the latest and greatest HVAC product led the industry with the longest warranty period. Very often this only lasted a short period of time as other Manufacturer’s would continue to match warranties with their line. Things often got out of hand as warranties have reached ‘limited lifetime’ on parts like compressors or heat…

There has been much ado about the recent paper published by E2e; Do Energy Efficiency Investments Deliver? Evidence from the Weatherization Assistance Program, the final word on which is yet to be written.
Decades of experience and verification prove energy efficiency programs deliver huge benefits to consumers and the environment - and these benefits far exceed the costs. But numbers can be distorted and therein is the bane of Energy efficiency projects.
E2e has some heavy…Continue
