Remember the word "Plastic" in that famous movie I can't remember the name of, but Dustin Hoffman was the kid. My stroke last year is no help either.

Here's the next word for all of you:  THINSHELL, both with metal stud framing and without, is the single biggest development in the world of construction and the AEC industry, and I invented it about 35 years ago in Hawaii.

Tilt-up die hards bemoan the entry of the replacement for common, thick, heavy conventional tilt-up but…

A/C a Necessity in New England?

  I remember not all too long ago, yes I am still on what I hope to be the first half of my life, that Central Air-Conditioning was a luxury.  Like the radio, then the television; next the telephone, and now the cell phone, Air-conditioning has become a necessity.  What was before Air-Conditioning?  What did the weather people (yes, politically correct here on Excess Air) say to the elderly before they would recommend "staying inside, out of the heat"?

  I remember what I used to do…

Not getting it

I live in New England, New Hampshire, to be specific, and I just don't get the lack of seriousness about weatherization and credentials here. I'm BPI Certified Building Analyst and Envelope Specialist, have taken the Resnet Energy Smart Contractor test, have OSHA 10, lead certified renovator, the list goes on and on. Means nothing here. Area contractors insulate to be just good enough and nothing more. I can't tell you how many times that I have gone to a new construction job and have been…

Weatherization Program Brought Back to Stability for FY 2013 and 2014

I recently received the email below from a fellow supporter of the Weatherization Program regarding the current status of Federal funding for the Low Income Weatherization program.  

Relatively speaking, while I have done little in terms of personal lobbying in DC at the Federal level on Weatherization, Brad Penney deserves credit as one of the greatest leaders in personally convincing members of Congress to fund the Weatherization program during the FY2013 and 2014 - the two years…

Why the President's Climate Change Proposals Don't Matter!

1. Not many will listen to him, as 50% of the US population are right-wing  registered republicans(me too sorta, but a moderate!)

2. China can't be persuaded in any way shape or form to change their prodigious rate of economic growth & CO2 production. btw, we owe, we owe them! we are a debtor nation, to the enemy!

3. If you control coal-fired plants here, the coal interests will simply sell more U.S. coal to export!

4. We're past the global…

Changing The Way We Use AC

Aside from vacations, longer days and spending time in the great outdoors summer brings with it oppressive heat resulting in large segments of the population blasting the AC.

This often translates into long hours of high energy usage which, depending on how much its relied upon, has a tendency to become routine throughout the warmer months.

Since AC spikes power usage more than most other…

Warning: This Blog Post Contains Gross Generalizations

I try to avoid generalizations, especially the gross kind, but sometimes you have to climb up on the mountain to get the big picture.

Window Improvement vs. Window Replacement

Most energy audit reports place windows very low on their list of energy improvement priorities. This isn't surprising because of the relatively high cost of replacement windows coupled with what are commonly marginal improvements in their thermal performance. Since audit reports generally prioritize energy efficiency improvement opportunities according to their cost vs. thermal benefit  (fuel savings) ratio, the energy…

Zero to 60 - Scores of Green Appraisers Hit the Streets Overnight in Colorado

Home builder Sean Smith feels like Sisyphus – the Greek mythological figure doomed for eternity to push boulders uphill only for them to crash downhill when he neared the top.  Smith’s boulder?  Higher appraisal prices for the green homes he builds in metro Denver.

Code Conflict Between 2012 IRC and 2012 IECC

It has come to my attention that there may be a building science-based conflict in the language of the 2012 International Residential Code (IRC) and 2012 International Energy Conservation Code (IECC).

The 2012 IECC sets the mandatory blower door tested and certified air infiltration rate at 5 ACH50 in CZ1 & 2 and an even tighter 3 ACH50 in CZ 3 and above. The problem lies in the fact that the new…

Home Performance and HVAC Contractors: Recent Legislative Initiative In Texas

As energy auditors and raters went about their business of testing homes, performing energy audits and HVAC system inspections, they discovered and reported certain “problems” to the homeowners of Texas. For example, they reported that HVAC systems were oversized, or suffering from massive duct leakage! In late 2011, The Texas Department of Licensing and Regulation (TDLR), which oversees the HVAC industry,…

Three WWWs to completing the Appraisal Institute’s Residential Green and Energy Efficient Addendum

The Residential Green and Energy Efficient Addendum is a form used to standardize the reporting of high performance house features from green certifications to incentives offered.  The Addendum can be downloaded in a PDF format from the Appraisal Institute’s Website.  It is seems there is much confusion on who should be completing the Addendum, why they should complete it and what they…

Excellent PBS Energy Program Worth Watching

In case you missed it, PBS has been airing a series "EARTH: The Operators Manual".  The  recent episode which aired last week "Energy Quest USA" is well worth watching...

While many of us discuss methods and marketing for audits and retrofits, I believe it is the community neighbor-to-neighbor programs and activities that engage the homeowner and get results. The show profiles communities making smart energy choices based on economics and the environment. Below is a link to the…

Prior to any real consideration of adopting alternative energy sources like wind or solar, it is paramount to consider a homes energy inefficiencies.  Cost savings are negated, almost immediately, when you attempt to power a home through revolutionary methods and antiquated building materials / practices.

The two subject matters have to be in congruence for the conversation of 'renewable', 'green' (whatever that really means) and 'sustainable' to carry any relative meaning.
