Retrotec replied to Craig McManus's discussion Inventions that save energy, licensing to a US manufacturer?
"If these blinds are on the inside, a fair bit of the heat winds up indoors anyway. I used to have highly polished metal blinds inside my apartment in Vancouver (cool climate) and my apartment would still go over 110 degrees from one sliding door…"

Retrotec replied to Diane Chojnowski's discussion Polls
"I am impresssed with those numbers visting the site but also notice that videos that have been up for monthes receive a small number of views and often questions posted get no response. Just what I see. "

Retrotec replied to Diane Chojnowski's discussion Polls
"We have made numerous postings and support the "Pros" to the extent we can but the number of users is very low making it marginal at best. We occasionally mention the website during our Webinars as a good source for information but would like to…"

Retrotec commented on Building Performance Journal's blog post VW Isn't the Only One That Circumvents
"The most flagrant circumvention is surely the fact that less than 10% of all duct systems meet code.  I would like to hear from others regarding the duct testing figures they get on new houses. Some anecdotal evidence shows that 250 CFM at 25 Pa is…"

Snap together this Aluminum Frame then disassemble in less than a second. Square corners make it ideal for Passive House testing, whether you use a Model 200, 300 or Duct Blaster fan. Regular and Large sizes available that go up to 130 x 51 inches!

Retrotec replied to John Carton's discussion Smoke Puffer stick
"Retrotec Smoke Puffer is available for pickup from Energy Federation. They will not ship them due to high cost of hazardous packaging and fees.

I think it's still the best one to use since the delivery of smoke is easy to…"

Retrotec commented on Chris Laumer-Giddens's blog post Building Science is Worthless...
"We have passive house tester complaining the Aluminum Frame leaked too much so we measured them at about 2.5 square inches mostly due to the notched out corners.  We created a new frame with corners that are square and reduced that down to less than…"

Retrotec commented on Retrotec's blog post What needs to be done to get builders to follow Code for duct and envelope leakage?
"Ironically, for the cost to the builder of one lawsuit, they could eliminate 20 times the duct leakage the Code allows in 2000 homes. You can argue about the match both ways.
In the former case, the builder's reputation would sink.
In the latter…"

Retrotec commented on Retrotec's blog post What needs to be done to get builders to follow Code for duct and envelope leakage?
"George, history shows you are 100% correct. Irony is that sealing ducts is the least expensive measure a builder could take to improve performance. There is a group in CA that gets duct leakage below 5 CFM.

Ted, ratings and predictive energy models…"

Retrotec commented on Retrotec's blog post What needs to be done to get builders to follow Code for duct and envelope leakage?
"The more anecdotal evidences such as yours the better. Overall, we have trained Code officials in many states but since many homes aren't tested at all, it is up to homeowners to let us know their experience.
We have a project underway to look into…"
