<div>Hi Jill,</div><div> </div><div>I'm resending my reply because it got bounced from the mailing list because I sent it from my other email by mistake. Sorry for clogging your inbox.</div><div> </div><div>Here's the original:</div>
<div> </div><div>Pacific Northwest National Laboratory (PNNL) released a report "Analysis of Energy Saving Impacts of ASHRAE 90.1-2004 for the State of New York" that compares ASHRAE 90.1-2001 vs 2004. For school buildings in three different cities in New York they found percent savings in site energy use of around 7%. You can find the report here: <a href="http://www.energycodes.gov/publications/techassist.stm">http://www.energycodes.gov/publications/techassist.stm</a>.</div>
<p> PNNL also did a similar report for some Gulf Coast cities, "Analyis of Energy Saving Impacts of New Commercial Codes for the Gulf Coast", comparing ASHRAE 90.1-1975 vs 2001 vs 2004 that can be found at the same link. They found incremental improvements for school buildings of around 7-10%.</p>
<p>They also recently released a report, "Achieving the 30% Goal: Energy and Coast Savings Analysis of ASHRAE Standard 90.1-2010", looking at nationwide energy savings for different building types from ASHRAE 2004 vs 2010. That one can be found here: <a href="http://www.energycodes.gov/publications/research/documents/codes/PNNL-20405.pdf">http://www.energycodes.gov/publications/research/documents/codes/PNNL-20405.pdf</a></p>
<p>Hope this helps,</p><p>Sam<br></p><div class="gmail_quote">On Wed, Apr 4, 2012 at 11:44 AM, Nathan Miller <span dir="ltr"><<a href="mailto:nathanm@rushingco.com">nathanm@rushingco.com</a>></span> wrote:<br><blockquote style="margin:0px 0px 0px 0.8ex;padding-left:1ex;border-left-color:rgb(204,204,204);border-left-width:1px;border-left-style:solid" class="gmail_quote">

This one specifically compares 90.1-1999 with 90.1-2004 for commercial buildings, which is the closest I could find to your specific request (2001 is just 1999 + addenda, isn’t it?).<br><a href="http://www.energycodes.gov/status/documents/determinations_com_dif04.pdf" target="_blank">http://www.energycodes.gov/status/documents/determinations_com_dif04.pdf</a><u></u><u></u></p>
