eric anderson replied to Dan Wise's discussion Convert BTU/hr in a Manual J to actual fuel usages
"Morgan, From the perspective of the energy auditor, I don’t agree with that statement. “Actual fuel and electrical usage" is anecdotal at best” Unless you change something, the best predictor of future energy usage is past…"

eric anderson replied to Dan Wise's discussion Convert BTU/hr in a Manual J to actual fuel usages
"Bud, I think these 2 articles will help illustrate the difficulties of modeling energy usage. http://www.nrel.gov/docs/fy11osti/51603.pdf http://www.sustainablybuilt.com/SB_Modeling_Software_Presentation.pdf The first speaks to the common …"

eric anderson replied to Dan Wise's discussion Convert BTU/hr in a Manual J to actual fuel usages
"Bud, The question was how to translate- from design heat loss calculated by using  ACCA manual J protocol to a yearly fuel usage.   I outlined a crude way to do it.  Is it perfect? Nope.  There are a lot of caveats to…"

eric anderson replied to Dan Wise's discussion Convert BTU/hr in a Manual J to actual fuel usages
"Dan, As a ballpark figure, take the design heat loss and divide by design temp difference, this gives you btu’s per °F per hour.  Multiply this number by 24 hours (per day) and then multiply by heating degree days to get yearly …"

eric anderson replied to Kaushal Bharath Raju's discussion On the Question of Airtightness and Energy Performance
"Older buildings typically  are 6-15 ACH50   worst I have personally tested was 17 ach50.  The energy loss  scales ~ linearly with ACH50 so If you go from  17 to 1.7, the heat loss from air leakage is reduced 10 fold.…"

eric anderson replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"Graham, That is why I called out the air tightness specifically.  Why stop at 0.6 ACH50? Why not 0.006 ACH50?   I will lay out my rationale for 1.5 being a good number. Think about it this way, the OP has a 1000 SF ranch.  …"

eric anderson replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"I think in all this you are getting bogged down in the law of diminishing returns We are talking about a small house, in a sub 3000 heating degree day climate.    If we took my own house ~ 2200 sf of conditioned space, and plunked it…"

eric anderson replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"David you are right of course-  that is why I made no claims as to the accuracy, I called it a half assed plan.  I don’t know Cali- at all.  I have not set foot in the state in 28 years.  From what I remembered  it was…"

eric anderson replied to Kaushal Bharath Raju's discussion Affordability & Deep Energy Upgrade/Passive House Retrofit in Berkeley, California.
"This is my no calculations half assed energy based  renovation suggestions- First off, Berkeley is a mild climate, If I lived there I might not even bother with heating.   For a small house a Minisplit heat pump system is a no brainer…"

eric anderson replied to Craig Bird's discussion Insulation/venting/air barrier for cathedral ceiling
" I would cut  1 inch strips of 3/4” pine as spacers  to go between rafters and use 3/8” plywood ripped to 14 ½  to create a ridged air channel from soffit to ridge vent, foamed edges to airseal. I would add…"
