Don Hynek replied to Brandon Walton's discussion When is it too windy to use blower door?
"You did a pretty good job -- there are a few tricks of the trade that might have improved precision AND accuracy a little. The most common is to run outdoor reference hoses to either windward and leeward sides, or even to all four sides of the …"

"First of all (as has been noted) it's good you are getting an electrician in there. The current configuration sounds like a hot mess. That said, this electric use COULD be perfectly believable without dealing with an electrical defect.…"

Don Hynek replied to Jim Fowler's discussion TREAT modeling of mid-rise apartments low heating load
"This isn't uncommon -- senior buildings often have lower-than-typical baseload use; especially for domestic hot water. More generally, though -- TREAT DOES have inputs for t-stat settings, water heater settings, space heating schedules, etc. I…"

Don Hynek replied to Energy Wise Solutions's discussion What causes a temperature plane in a home
"With enough details, I can now provide a practical response... This is what HVAC guys call "stratification". Warm air is less dense than cold air, it is pushed up to the highest level in the home to which it can easily flow. The…"

"Tyvek (tm) air barrier is sealed to the concrete and run up onto the sheathing before the foundation foam goes in. Then a z-flashing sits right on top of the foundation insulation, and is taped into the Tyvek. . And, this is Wisconsin.…"

David Eakin replied to Don Hynek's discussion Superinsulation retrofit is Complete!
"Don - thanks for the additional detail and design info. I do understand cost decisions (there is a current blog on Fine Homebuilding that speaks directly to that decision) and also wonder if ANY current mechanical devices have the longevity desired.…"

Don Hynek replied to Jack Baikoff's discussion Vermiculite in the fireplace
"Our weatherization protocol (based on Wisconsin DHS rules) says there is no reliable sampling protocol for asbestos  in vermiculite. The reason (I am told)  is that the asbestos fibers laid in veins in the original ore, and not dispersed…"

Don Hynek replied to Don Hynek's discussion Superinsulation retrofit is Complete!
"Correct -- for cold climates. That's why this REMOTE system is ideal for retrofit in OLD cold-climate  houses, and for new construction anywhere. The key is that the sheathing (the outermost wood layer) is the "break point." The…"
