"That's a great link, thanks for sharing it! I agree with you about not venting subslab vapors through ambient air. It looks like Lstiburek's approach is similar in the sense that the concrete slab acts as a heat sink. "

Nick Helmholdt replied to Nick Helmholdt's discussion How to Add a Passively Cooled Wine Cellar?
"Thanks for the reply! This sounds like a promising approach. The slab is about 600sf, uninsulated and >4' below grade, so I think it could work as a heat exchanger. According to this site, a 25sf area would accomodate the size of the cellar…"

"Thanks for the link. Part of the reason I was asking was exactly because of my concerns of punching holes in a perfectly good foundation wall. "

"I suppose I meant passive in the sense that I don't need to add a dedicated A/C system or supply line to the room - so a fan would fit the bill. The moisture build up is a concern of mine, too. "

Backdraft Detectors - Are they reliable?

On a recent Quality Assurance site visit, I found a gas-fired water heater with a "Vent-rite Spill Alarm" installed on the flue. The contractor noted that worst-case spillage and draft failed in this home both on the test-in and test-out. I had heard of folks using these alarms, but had yet to see one installed until…See More

CO in Attached Garages

On two separate Quality Assurance site visits in the past two weeks I've detected elevated levels of Carbon Monoxide (CO) coming from attached garages. I was a bit surprised at this since neither garage contained a car - let alone any active source of combustion. So I did some digging and came up with this great resource from Iowa State on the topic. From my reading of…
