Controlling Airflow in Existing Dwellings

"You did not add the (other) expected yearly running costs for the ventilation unit (additional air conditioning costs for heat/coll/dehumidify, any replacement parts/service, etc.) in the initial SIR computation; you only talk to the fan electrical…"

David Eakin commented on Brett Little's blog post Despite record breaking cold winter our MI GreenStar Certified home saved 50% Energy!
"Brett, PA (like most states I presume) is a hodgepodge of compliance. All depends on what the local building codes require. One nearby township still does not require duct testing for new construction. Most have adopted most/all of the IECC 2009 but…"

David Eakin commented on Brett Little's blog post Despite record breaking cold winter our MI GreenStar Certified home saved 50% Energy!
"Brett, Good work! I know it's frustrating that you put so much work into your home and it now only tests out as "average" (not even "code"). Not knowing all the particulars I can see some areas you might want to address to…"

David Eakin replied to Craig Savage's discussion Leveraging other trades to get EE
"Craig, This will never work with finish carpenters as they have different criteria to judge their work. For an example - check out the This Is Carpentry instruction on installing baseboard trim and inside/outside miters. It is sometimes necessary to…"

David Eakin replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"Eric, 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…"

David Eakin replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"Eric, 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…"

David Eakin replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"More food for thought on this subject - read this (fairly) recent blog by one of the most respected authors today about deep energy retrofits: Green Building Advisor - Deep Energy Retrofits"

David Eakin replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"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,…"

David Eakin replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"Kaushal, 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…"

David Eakin commented on Anna Jursik's blog post Could a Certificate Motivate Homeowners to Invest in Efficiency?
"Anna, 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…"

David Eakin commented on Chie Kawahara's blog post Passive House Delivers 80% Energy Reduction in a 90-year-old House in Santa Cruz
"Chie, 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…"

David Eakin replied to Roy Sakamoto's discussion Whole house air leakage
"Don, 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,…"

David Eakin commented on Chie Kawahara's blog post Passive House Delivers 80% Energy Reduction in a 90-year-old House in Santa Cruz
"Graham, 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…"

David Eakin commented on Chie Kawahara's blog post Passive House Delivers 80% Energy Reduction in a 90-year-old House in Santa Cruz
"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…"

David Eakin replied to Roy Sakamoto's discussion Whole house air leakage
"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…"
