Hi Jill,

 

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.

 

Here's the original:

 

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:
http://www.energycodes.gov/publications/techassist.stm.

 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%.

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:
http://www.energycodes.gov/publications/research/documents/codes/PNNL-2040
5.pdf

Hope this helps,

Sam

I swear I've seen some graphs before showing the progression of 90.1 and
the relative savings between cycles. It is, of course, highly dependent on
your building type and climate.

 

Here are some useful links to DOE reports that will probably help you
(check out the "Determinations" for quantitative comparisons):

http://www.energycodes.gov/analysis/#savingsEstimates 

 

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?).

Hello,

Does anyone have a feel for a percentage savings going from the 90.1-2001
to 90.1-2004? For example, if a school building achieved a 38% savings
over the 2004 code, what would the estimated savings range be as compared
to the 2001 code?

Thank you,
