My 40 foot sailboat is only about 100 ft2 of floor space, the surface area is more that of a mobile home - long and narrow, the hull and deck are about an R-5, the glass is all single pane, and there…Continue

Cold climate wall

Started this discussion. Last reply by Don Hynek Jul 11, 2014. 2 Replies

I have heard Joe Lstriburek twice say that a wall in this climate (Albany NY, almost 6,000 DD) should have 1/3 of the R-value on the outside of the structure and 2/3 in the cavities to prevent…Continue

Concerning duct testing in crawlspaces (this is for new houses for Energy Star, but will be the same for existing houses):I have a house on a conditioned crawl with ducts in that crawl.  There is an…Continue

"Chris I agree, and then notice that puts the duct system outside of the house.  So the duct systems frequently have to be rebuilt, sealed and then insulated.  And if the return system is a series of holes along the edges using the…"

"Glad to see they went with 5 ACH50.  This is very easy to achieve in even small houses and with your minimal DD in both heating and cooling seasons, the need for very low numbers is not there.  "

Ed Minch commented on David Byrnes's blog post Why Phoenix Is Called "The Land Of No Return"
"The blanket statement that one return is no good is no good.  The reason your second return finally worked is because your first return was not big enough.  We see this all the time and if you added the same second return near the first…"

Ed Minch replied to Rob Madden's discussion Where is the money in energy auditing / home rating?
"We divide the business into 2 parts - energy audits with retrofits, and new home airsealing with perhaps 50% getting a rating for Energy Star or other reasons.   I think that ratings on an existing house are a non-starter right now because…"

Ed Minch replied to Diane Chojnowski's discussion One of the most efficient homes in America
"In addition, $6K per year for a an energy bill is astoundingly high, unless the house is very big.  In my mid-Atlantic region, a house with a HERS of 80 uses less than $1 per square foot per year, so in Florida with no heat and more A/C it…"

Ed Minch replied to Diane Chojnowski's discussion One of the most efficient homes in America
"I understand.  But it sounds like, with a HERS rating of 80 before the addition of renewables, that the energy efficiency features of the actual house are unremarkable."

Heat and A/C on a boat

My 40 foot sailboat is only about 100 ft2 of floor space, the surface area is more that of a mobile home - long and narrow, the hull and deck are about an R-5, the glass is all single pane, and there are skylights and hatches that let in ALL of the sun, so how do you calculate the conditioning needs for winter and summer?  Tricky and lots of rule of thumb going on, but here is an interesting article that uses all the techniques we have for homes:…See More
