Yes - you and I are in agreement. My response was more for Kaushal; doing a renovation for energy savings is not easy nor often a good payback. My brother and sister-in-law live outside Oakland in a '50s ranch that has had little thermal…"
OK - but what about the most common air/thermal leakage point in the CA homes I've seen: the completely open crawlspace (often with suspended return ducts)? Or the ceiling perforations (access hatch, recessed lights, attic supply duct…"
"I mis-spoke - I was referring to the Midori House in Santa Cruz. Have an in-depth discussion with the owners to see what their total cost-per-square-foot ended up. There is the cost of deconstruction (labor, alternative residence costs,…"
There was a deep energy retrofit upgrade project (to Passive House standards) in San Jose posted on these boards not too long ago and the home owners decided to do the retrofit for the same reasons you state. You could contact their…"
This program looks like it may have merit, but many questions remain. I am in total agreement on the "what" and "why" of the program, just not sure of the "how". Many details are not in the CEE report - like…"
I base that on a (somewhat generous) observation of many homes over much observation time. You said that your home originally suffered from "deferred maintenance" (very generous). This also happens to many (but not usually most) used…"
I'm not sure I follow. Is it because the 2012 IECC does not include the basement area as conditioned space, or that slab houses are viewed as being "leakier" than houses with double the flooring footprint and having a basement,…"
I read through all the blog entries - very informative and entertaining. I also noticed that from start of deconstruction to full-time occupancy took 15 months (with several months' ownership prior during the fact finding/design…"
"Very interesting! It also points up one of the sad facts of older home improvement - if you "kept the foundation, most of the framing, floor and roof. Everything else was replaced." and it took you 2 years to complete, what was that…"
"I have been thinking quite a bit about this topic recently, and the more I think about it the less convinced we are on the right track.
First - blower door tests DO NOT give an indication of air infiltration; they give a slight indication of the…"
I agree that occupant usage skews historic energy usage records, but what better way is there for a potential home buyer to get a "ballpark" picture of energy usage?
I have also seen some interesting technology shelved due to…"
I well understand the difference in operating costs, but I was referring to the general perception (sometimes rightly, sometimes wrongly) of total cost of ownership, which includes initial purchase price, running costs, anticipated repairs…"
I am seeing a radical shift in viewpoint among many Americans in general - that from an "owner" mentality to a "renter" mentality. An owner thinks about maintaining their physical possessions in good working order; in…"
Who places photos in the MLS? Real estate agents. What is the real estate mantra? "No house is a bad house, it just needs the right customer" regardless of how terrible the condition or how large an energy hog. No real estate agent…"
