    A combination of project fatigue and financial fatigue meant we didn't get to a planned countertop for our kitchen island. Instead, I had a sheet of prefinished maple plywood left over from the ...

    Scott, I appreciate your stance. I will "correct" a couple of things. I'll move some light switches, and ad a MUA switch by the wood stove sooner rather than later. I just need to get up the ...

    We do a lot of certification with all the "point" programs and there is a lot of gaming, as well as a lot of energy expended trying to figure out what to do and what not to do. I like simple ...

    So is using a material like Mento 1000 roof underlayment an acceptable air barrier? What other options would be good?

    Jonathan, Oil-fired water heaters are expensive to purchase and require a lot of maintenance. I don't recommend an oil-fired water heater for a single-family home. So your two choices are to ...

    No biking for me, so the fact that there's ten pounds more of me than when we moved in may very well be because we didn't have a pantry in our old house. Such a convenient location for snacks!

    Peter, You need to get another installer. Your installer is ignorant. The synthetic roofing underlayment suggested by the installer (a) is a roofing product that is not designed for use on ...

    Energy audits are usually subsidized by utilities or some type of energy-efficiency agency for a reason: If homeowners had to pay the full cost of an audit, audits would rarely be performed. A ...

    Michael, The cooling load is much too high. It looks like the heat gain assumptions for glazing are based on double-pane clear glass. That type of glazing is illegal. Your windows must have a ...

    Bob, The first piece of rigid foam that you describe, inserted between the rafters, is called a site-built ventilation baffle. You can use 2 inches of rigid foam if you want, but that much rigid ...

    Cliff, It's possible to do as you propose. That said, it is rarely executed well, and the usual result is air leakage somewhere -- air leakage that results in unusual snow melt patterns on the ...

    The one we got from our local utility was completely bogus. The guy gave only two recommendations, both of which directly contradicted advice from the Department of Energy at ...

    The number came right out of a room by room manual J calculations I paid a local company to do. They farmed it out to an engineering firm to do the actual work so I've never been able to speak ...

    Six tons sounds like a huge oversize. The main level isn’t that large and it shouldn’t take much capacity to heat and cool the basement. What does the HVAC engineer say to justify his/her ...

    Rod, I would find it extremely hard to believe that any county would have code amendments that prohibit any advanced framing techniques. You've got to remember that the advanced framing ...

    Sorry, I forgot to add that the attic will be R70 blown insulation.

    A few more tidbits: I have already planned on using liquid applied evaporation reducer on all surfaces (front porch, garage and house slabs). Apparently they use Diamond Clear 350, which looks ...
