Michael Blasnik replied to Sandra K. Adomatis, SRA's discussion HERS Index tracking 5 years or more after construction
"I guess I don't understand what you mean by factual studies -- I would think comparing actual energy use to projections from the ratings across many thousands if homes and then also looking over multiple years would be considered a factual…"

Michael Blasnik replied to Sandra K. Adomatis, SRA's discussion HERS Index tracking 5 years or more after construction
"You might want to check out this study of homes in Houston that included tracking of actual energy use over time after construction for up to five years (see pages 33-34) among other things.…"

Michael Blasnik replied to Bud Poll's discussion Hot air language
"Ed- I didn't comment because you nailed it in your first comment (mystically de-levitate!). Sorry Bud, but hot air rises and cold air falls. It's fine if you want to push people to say both instead of just the hot air part, but I've…"

Michael Blasnik replied to Colin Genge's discussion What is the value of using a pressure pan to test outlets?
"John- I think I can answer this one as well.  The pressure will equalize pretty much instantly in all of the building cavities.  The only exception would be for cavities that are extremely tight -- as in much less than even 1 CFM50 of…"

Michael Blasnik replied to Tim Marlett's discussion Blower Door Depressurization and the Human Ear
"This concern is rather silly. The pressure difference created across the ear by a blower door is on the order of what an elevator ride up 3 floors would create or sliding diwn a tall slide. It's much smaller than taking an elevator up a high…"

Michael Blasnik replied to Colin Genge's discussion What is the value of using a pressure pan to test outlets?
"Colin- I just have to chime in here - the dP across the pressure pan has nothing to do with how leaky the outlet is. When covered by the pressure pan the outlet leak has no flow - it has become a pressure tap into the wall cavity. The pressure is…"

Michael Blasnik replied to Classic Residential, Inc.'s discussion Learning Thermostat
"a slightly more polite answer gets a reply to your questions: TK> For me, 5% of total consumption (not just heat) would mean less than $50 a year.  Do you think it would be fair to say this savings is so small as to be a rounding error?…"

Michael Blasnik replied to Classic Residential, Inc.'s discussion Learning Thermostat
"Ted- "True proof of savings is logging temperatures" ? really -- I thought true proof of savings is measuring energy use before and after in large scale studies.  Isn't it energy savings we are after -- it seems like measuring…"

Michael Blasnik replied to Classic Residential, Inc.'s discussion Learning Thermostat
"Ted- When you declare the laws of physics or thermodynamics wrong then it should be up to you to provide some evidence to support your beliefs.  But I'll give you the benefit of the doubt.  I certainly agree that energy models are…"

Michael Blasnik replied to Classic Residential, Inc.'s discussion Learning Thermostat
"If you check out the more recent research (e.g., from FSEC and ECW) on AC sizing and read the recent Proctor article in Home Energy you will see that there isn't much energy penalty even for oversizing cooling systems.  Your claims about…"

Michael Blasnik replied to Classic Residential, Inc.'s discussion Learning Thermostat
"It seems like you have some sort of aversion (hostility?) to controlling temperatures in homes yet some sort of faith-based belief in the benefits of right-sizing and multi-stage equipment.  I've got some data on thousands of homes (and…"

Michael Blasnik replied to Classic Residential, Inc.'s discussion Learning Thermostat
"It seems like you are saying that setting back the temperature when you sleep or are away does not save energy -- at least if what you mean by "gaming operation" is temperature setback.  I've performed multiple studies for…"

Michael Blasnik replied to James White's discussion Using Average Monthly Temperature to Model Home Energy Use in the group Building Simulations
"It seems that we are getting closer to agreement on issue #2. In your initial post you said "The intersection of this line with the X axis, typically 70F, indicates the average temperature maintained inside the home." I disagreed with that…"

Hi, I'm a HERS rater, THC participant, CA Title 24 energy plans examiner, etc, and saw your talk at ACI.  Might you be able to make your Simple energy modeling software (I think you said it was a spreadsheet) available for my/our use.  I'd love to be able to show better prediction (retrodiction) of energy bills for my clients, some of whom have complained that the HERS Whole House reports are pretty far off, just like you said.  Many thanks.
