Residential Workforce Guidelines Part Deuce:

The U.S. Department of Energy (DOE) developed a draft Workforce Guidelines for Home Energy Upgrades with the goal to foster the growth of a high-quality home energy efficiency industry and a skilled and credentialed workforce. 

RESNET and a broad range of contractor associations had serious concerns with the draft and requested a second round of public comments.

DOE has agreed to seek industry input on the draft guidelines.  RESNET has been invited to part of this review process.  This industry review and comment process is open through July 22, 2011.  After the review DOE will make changes to the draft guidelines and open a public review in fall 2011.

If you are a member of RENET - send comments to by Monday, July 18, 2011

*** At first glance, it appears they listened to many of our comments & have eliminated a lot of the duplicate material & created a global section. Unfortunately they still have plenty of issues - like all fans WILL be orientated to final termination point (Nice but not doable in all cases) & hardly any mention of building codes, or using anyone licensed  trades (electricians are covered - not HVAC, plumbing, gas)

Now even if you don't belong to RESNET or your group has not sent out an email, I would encourage you to read through them & forward any comments you have to any "industry association" you belong to. If all else fails - create a thread above & I will add it to my comments & it may also get picked up by others

As an FYI, a new group has been created on here for historic homes by my good friend John D. Poole. It's mission is "Historic and vintage homes are significant to our cultural heritage, yet often lack energy efficiency and comfort. Our mission is to identify key issues, solutions, and best practices when retrofitting much older homes."

As some of us know from experience, what might be a best practice or a semi-easy fix on say a ranch house, becomes a totally different animal when you are dealing with a Victorian house built in the late 1800's, etc... So if historic homes are in your area, you are just interested, etc... I encourage you to check it


Speaking of items to check out, I also encourage everyone to check out the discussions above, add in your 2 cents or create a new discussion on

John most of the larger foam companies offer a system like that - to my knowledge this is Demilec's version which I have not used nor heard about.

I have heard some great things about Icenyne's version. I should also mention though - a few of their installers won't use it based on concerns of drywall popping off the walls (same issue with dense packing cellulose - if the wall panel isn't attached properly, it can blow off and make a big mess)

Do you have a link to the slow rise foam.  I haven't heard about that approach.



Comment by Sean Lintow Sr on January 18, 2011 at 3:41pm
John in many cases, those area's are so messed up around here, we end up rebuilding the exterior walls & occasionally the floors in those "porch additions". I remember one that still had the original railing and they framed above it with 2x2's. In those cases and it is still in good condition you are probably going to have to add it from the outside (i.e. foam panels) or consider using slow rise - pourable foam if you can from the inside

I've done several audits on houses built between 1900 and 1930.  They all have an area that is now either kitchen, bathroom or both. These areas look like they were a back porch originally. 

The construction seems to be lacking, no insulation, and 3 of 4 no room for insulation, and very thin.

I've been working with taking a window or 3 out of the wall. Trying to build insulation into the wall and doing some air sealing at the same time.  This seems to just be standard 2x4 and insulate then drywall.

Does someone have a different material approach or a different approach to these types of construction?

First I hope everyone is geared up & ready for a great New Year. I did change one option on this board which is the "send message to the group" has been disabled. This was done for two reasons - number one is to eliminate anyone using this for spam purposes, and the second is if you post a message there, no one can really answer it. So if you do have a question, best practice, etc... please post it in the Discussion area above so we can help you out or even learn something new. 


Now if you do have a question, comment, etc... and wish to post it anonymously, you can always add me as a friend & send it to me - I will gladly post it for you.

I would like to wish you all a Safe & Merry Christmas along with a bountiful New Year:

Happy Holidays to all and to all a little festive cheer… 

Festive cheer = links to Martin Holladays 4 Christmas Carols, Energy Circle signing the Blower Door Man is coming to town, a few parodies of the Twas the Night before XMas, and some great LED Christmas Light Displays

Merry Christmas everyone & thanks for joining in the discussions & emphasizing Best Practices

Comment by A. Tamasin Sterner on December 8, 2010 at 8:08am
Yep. We ask them what they think is going on that is causing the issue they are concerned about. We ask them how they feel about their energy bills. Mostly we listen.
Comment by Dennis McCarthy on December 8, 2010 at 6:18am
A good point ; wanting to know a homeowners expectations.
We ascertain the customers goals right away defining if they are trying to get 10% or 30% energy savings . Since getting 30% savings is more involved people appreciate choices ol what it cost to get 10- 15% Energy Consumption cuts.Ultimately its up to a home owner to decide what gets tended to . Weather stripping & use of quality Leds
Just these two combined tasks would save the ave h/o about 20% real costs- Both those tasks are something everyone can & should do.
As a solution provider I get paid to make the intel & insights I gather
come together to give people choices . Making the improvements
whether DIY or thru pros, what I think we would all agree with is that
now is the time to be making all of our bldgs more energy efficient,
using all the tools and talent we have!
