  1. Look, I don't want to frustrate anyone here. I am just trying to weigh the different opinions and balance that against the reality of the building's present condition and history, and the intransigence of those actually having the power to make changes in it. Some final(?) questions for anyone who has experience with closed vents in unconditioned crawls: Regulations and heating efficiency aside for the moment - As long as the crawl spaces remain relatively dry, why would we want to have open vents in the summer introducing humidity laden air that is very warm? There is, in reali
  2. This is not an option. That being the case, how would you vary the vent positions during the year? Are you saying the vents should be open year round? Your post raises some interesting points. Let me say - The building is 20 years old. There does not appear to be any water penetration or vapor issues. When asking about crawl pressurization, we were told by more than one professional (including our HVAC tech) that our building is not so tight that it would be a problem. Assuming this to be true, if the vents were closed wouldn't the stack effect draw air into the crawl through cracks, chea
  3. Thanks for the link. (How come my links get broken and yours didn't?) The trouble with the articles/studies linked from the advancedenergy.org page is that they all focus on "closed crawl" = conditioned crawl - and conditioning is not an option for our condo's crawls (because they are linked in pairs with no fire doors between = too expensive to upgrade + and other reasons). What I wish I could find is an article something like: Proper Use of Crawlspace Vents - When Conditioning is Not an Option. If anyone knows of such a piece, pls let me know. I contacted my home inspector again about
  4. I haven't quite given up on them yet. Are you saying that our "vented" crawls would be better served if the vents were shut year round as our home inspector suggested (providing the space is dry, has a vapor barrier and insulation on the walls)? Also, do you know where I could find an article supporting this?
  5. I appreciate this forum a lot, but wish there was a way to edit one's posts. These links should work. Bloomington average temperatures http://pics2.city-data.com/w1q/lhaq7716.png Bloomington average humidity http://pics2.city-data.com/w2q/humq7716.png
  6. Don't bother. They're garbage. Like most HOA boards. There isn't much to do here; if they don't want to listen to what's proven to work, that's their prerogative.
  7. In our building there are 4 crawlspaces, but they are linked in pairs with no fire barrier door between them. In November 2010 the HOA Board wanted to condition the crawls, but after I got a County Buildings Dept inspector advising, he pointed out how expensive the code compliant options would be. They went back to the as-built state: vapor barrier on floor, fiberglass insulation in joists, foamboard on exterior walls and just now, these automatic vents. Our home inspector at time of sale advised leaving the vents closed all year. BTW, I got much help from you folks here back in November.
  8. In the available (south and west) foundation walls of the approx 2000 sq ft crawl space under our Bloomington, Indiana condo building, the maintenance crew has installed Solar Tek automatic foundation vents (bought at our local Menards or Lowes). What few reviews I can find online indicate that performance of this type of "automatic" vent is problematic. Anyone have a performance review to offer here?

  9. Thanks, but it isn't costs that I wonder about. My concern is residents leaving the units vacant for extended periods with HVACs set at minimum settings (or with AC turned off during a summer away from the unit) - my question being: Given changing weather conditions, is it likely that the lack of attention or oversight during such absences would affect humidity/vapor issues in the crawl and potentially lead to mold, etc.?
  10. In November I posted a number of questions here re the proposed conditioning of (connected) crawl spaces under our small Bloomington, Indiana condo building. With the help offered here and that of the local Buildings Department, the plan was abandoned by the HOA and they opted to stick with the passive vented system (probably with the vents closed year round).

  11. Sorry for my sloppy typing. Correction; this should read: I read on another site that 2" deep spray foam might cost $2 sq ft. x 1000 sq ft @ = $8k. There are actually 2 buildings, so this number would be $16k.
  12. Thanks. I think I understand the concept of radiant heat better now.
  13. Situation: Attached 2-story, 20-year-old condo buildings located in south central Indiana (Bloomington), with 4 connected first floor units above approx. 1000 sq ft. vented crawl spaces approx 24" h. The crawl spaces are connected in pairs. A year ago we shared our pre-buy inspection report with the HOA. The main crawl space issues were that a lot of fiberglass insulation was hanging down and the vents needed to be repaired or replaced. I assumed they would clean the place up and replace any batts that needed it. Instead, the HOA board contracted to have the spaces "conditioned" without se
  14. As far as I know, the board isn't trying to "weasel out of resposibility" and they haven't cried "volunteer." I am just stating a fact: at the annual meeting it was very hard to get enough people to volunteer to be on the board - and I didn't offer to join. I have urged my wife to join. She says she has enough to do keeping me out of trouble. I have done more than enough yelling in my life & am trying to be calmer. I have no power to "stop the presses" and have no intention of hiring a lawyer. I believe my actions so far have moved things in a better direction. They know more abou
