EcoSmart Fireplaces...are they really a smart choice?
What is your experience and/or thoughts on the EcoSmart fireboxes/fireplaces that are burning denatured ethanol? Are they any better or worse than the dreaded ventless gas fireplaces in a tight…Continue

For my customers, the cost of getting a tight house is right up there with actually HAVING a tight house. We deliver houses on a production basis below 1.5 ACH50 all the time (1800-2600 ft2) without any expensive materials. In my…"

Bob Blanchette commented on Chris Laumer-Giddens's blog post Installing Ducted Mini-Splits and ERV in Modern High Performance Home"I'd say with a low load house there is less of a need for high tech HVAC systems. As loads lower, payback times become longer vs. a conventional system. It becomes a matter of comfort more than energy savings at some point."

Designing A Perfect Residential Wall - Atlanta, Georgia
Atlanta, Georgia has a reputation for getting pretty darn hot, but it can also get pretty dang cold (No snickering from you Northerners, please!). Believe it or not, Atlantans use more energy to heat their homes than they do to cool them. The design temperature set by …

John Poole said… Hi Chris,
I think that's a great idea! Yes, we should do that. Want to try to talk about it a little later this week? I am extremely busy until tomorrow evening, but should be relatively free Thursday or Friday. If you have some preferred time, let me know, and I can give you call. And I really liked your Cart Before The Horse article, BTW, just haven't had a chance to comment yet. Have a good one!

- Hi Chris, Agreed on all that. Review board issues are yet another problem area we could possibly draft some general solutions for. Also, I wanted let you know that my good friend Juliana Inman from Napa, CA, a highly experienced preservation architect, has also joined HEP and our group. She's been through much of what you're descrbing and will be a great asset to the group. Regarding the presentation, I doubt there'd be any recording, but I will definitely get you a copy of the presenation slides. Have a good one!

Thanks Chris!
And I'm glad you're excited about the Historic Home group. I am too. Wasn't aware of your preservation background, but I think it's great that you're in a position to combine preservation knowledge with energy efficiency. I think these are very important areas that need to be unified. I am in the process of compiling some detailed discussion topics to post to the group about the difficulties of retrofitting older homes and buildings. If you don't mind, I will run them by you for your input before posting. I think between you, me, Allison, and Sean, we can make this a very successful HEP group.
Also, just so you know, in two weeks, I am giving a presentation on three ancient homes that I am in the process of surveying, at the Timber Framers Guild spring meeting. I am using SketchUp to build timber frame models, along with some Ruby extensions that support the creation of timber components (developed by another Guild member). That's why I like SketchUp so much. Its application is almost unlimited.
Have a good one, Chirs!
