    Dr. Jim, In general, it's a good idea to air seal the areas that you have indicated. You will also probably need to install wind-washing dams under each of your ventilation baffles, and these ...

    Michael, Because the climate here in SW BC is so temperate but wet, covered outdoor living spaces are one of the things I always include in a house design. There are a couple of strategies to ...

    Thank you Martin. I am hoping Dana will chime in. I do have some additional information regarding the Daikin VRV unit in question. I spoke with their tech support yesterday and they ...

    Chris, You should call up the contractor that performed the work, explaining your comfort problem. I'm guessing that the company didn't do an adequate job of assessing the size of the duct ...

    Thank Martin. My name is Chris G Fears. I paid for a reputable HVAC/home performance contractor to fix this room by doing an energy audit. Sealing all ceiling penetrations, adding more insulation ...

    Arden, I can't resist including a link to a relevant article -- even though it's too late for you to take the advice in the article. Here is the link: Plan Ahead for ...

    Michael, You haven't indicated the cardinal directions on your plans, so it's a little hard to assess the situation. [Later edit: I just noticed that the title of the illustration showing an ...

    Trent, Q. "I want to enclose my attic by using only closed-cell spray foam. What underlayment or membrane is recommended to place on top of the roof deck sheathing in two scenarios: 1) a hot roof ...
