Deconstructing and Moving a Historic Home

This spring in New Orleans I hosted “True Tales of Haunted Home Performance,” at the Home Performance Coalition National Home Performance Conference. I was joined in this true storytelling event by seven home energy pros, who contributed their real-life stories.

All the storytellers gave examples of what they had learned from the haunted houses they worked on, including John Tooley's heat pump from hell, and Chris Dorsi's haunted time capsule. We'll be reprinting these two stories in…

The Better Blower Door Test for Multifamily Energy Code

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…

2015 IECC Updates Help Homebuyers Make Informed Purchases

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…

This is using still and moving camera,   Then gets stitched with software.     Tell me what you think?   On the photo that move you slow it or speed it up or go all the way around.

What needs to be done to get builders to follow Code for duct and envelope leakage?

“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…

HVAC Industry: Who wins with High Warranties?

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…

ENERGY EFFICIENCY RETROFITS.....IN NUMBERS WE TRUST

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…
