    John, I'd be interested to know why you think that UFFI is "alive and well in the U.S.A. [and] Canada." A great many sources can be cited that show your statement to be false. For example, ...

    Mark, The walls of crawl spaces should be insulated with rigid foam insulation or spray polyurethane insulation. In some cases, it also makes sense to insulate the floor of a crawl space. In any ...

    Mark, Thanks for pointing out an interesting study. (If any readers are confused about what Mark is talking about — as I was at first reading — his comments refer to a study, "Analysis of ...

    Julian, Of course you're right that the Jevons Paradox doesn't account for all variables. The world is always changing. People make decisions for a variety of reasons — including their religious ...

    I’ve not read this in detail but the conclusion is interesting. Compared to an uninsulated concrete basement (case G47; 35,457 kWh), the largest reduction in the annual sensible heating load ...

    Martin, What I mean is that you gain multiple benefits from single expenditures - the all air system supplies heat and fresh air, two functions rather than one. This avoids capital cost and ...

    Alex you state that "UFFI is no longer produced." I suggest that you do a little more research before making such a assumption. The process is alive and well in USA, Canada, Europe, United ...

    Martin Jevons Paradox is really the evoltuion of human beings, nothing new this has been going on since time began. I do not see anyone changing that enough to have a real effect on our ...

    Brovo Chandler! Nice artical! thanks

    In case folks have not seen it, Duncan Prahl from IBACOS in Pittsburgh did one of the more-referenced papers on this subject back in 2000: "Analysis of Energy Consumption, Rating Score, and House ...

    Hello, I am doing a case study for my Sustainable Design masters at Carnegie Mellon University. I was wondering if you have metered data for at least 12 months for your home. Very impressed by ...

    Use the Certainteed Optima Blown in Blanket (BIB) dense pack fiberglass system for walls and sloped ceilings. Consider a layer of rigid foam on the exterior. Use Huber Zip Wall system. Use sill ...

    Try a spray on bedliner application - some guys are set up to do it mobil, although it is fairly expensive it looks great. There are also some industrial paint coatings that are now specified for ...

    This is a weak point. I recommend Solarcrete energy efficient building system to use. Wall begin below the frost line! - No energy gap. Same at top, roof line.

    Fact of the matter is that this article and the views of many of the comments do not take into consideration of other variables in the mix here. This article looks at consumption as a single ...

    If you really want to ensure the reduction of negative environmental impact a flat carbon tax needs to be implemented. It will not only shift consumer preference away from carbon intensive ...

    Overall, Daniel Morrison's article is right on. The last paragraph contains a typo: the LEED rating was indeed PLATINUM, not silver. Carl's comments are good to read but we are preaching to the ...

    Great story. What appliances are these?

    I got to 1.7 ACH50 in a SIP house I built, and that was before I'd ever seen or done a Blower Door test. I think the biggest contributor to the leakage was the band joist, which I didn't do a ...

    Thanks, Martin. That confirms my experience with Hardiplank. I'll have to check into MaxiTile.
