Jeremiah, <br>
Unfortunately, the envelope provisions, by construction class, did not increase in stringency linearly. By year in some cases a particular assembly increased relative to another, in some cases it did not change at all. So, unfortunatly,<br>
There is no easy ( accurate ) answer. As for generalizations, most of the analysis, has been on the standard as a whole, and therefore includes all the chapters.<br>
<br>
It seems, if you are creating a backwards tool, there are not too many assemblies, and only 3 editions to enter in the data. <br>
<br>
As for purchasing the standard, its not a bad reference. <br>

<div><font color="#336666"><font face="verdana,sans-serif">Dear list,</font></font></div>
<div><font color="#336666"><font face="verdana,sans-serif">I am working on creating envelope libraries for ASHRAE 90.1 2010, 2007 & 2001 code vintages. </font></font></div>
<div><font color="#336666" face="verdana, sans-serif">I have a copy of ASHRAE 2010 standard and users guide, and am wondering if there might be a general multiplier that could be used to back the insulation levels as well as U values down to the 2007 and 2001
levels. When I purchased the ASHRAE 2010 standard and users guide the ASHRAE rep I spoke with mentioned that I might be able to use a multiplyer for this. From what I recall insulation levels where raised by 16% for ASHRAE 2010 from ASHRAE 2007, but do not
know if this 16% is actually the number or not and do not have any assumed numbers for other vintages or values. My use of this is for PCM modeling, sort of conceptual massing preliminary modeling & climate studies so strict code compliance is not necessarily
required but would be preferred. I would prefer not to buy all of the individual standards if possible so wonder if such a multiplier might be reasonable. </font><span style="color:rgb(51,102,102);font-family:verdana,sans-serif">I would like to also do space
type lighting codes & DHW (for internal gains) as well.. </span><span style="color:rgb(51,102,102);font-family:verdana,sans-serif">If anyone has insight it would be appreciated, and I also could share my finished work (in excel, energy plus and design builder
formats) with anyone who wanted it..</span></div>
