[BLDG-SIM] source of benchmark utility consumption data

[Jon Maxwell]

The EPA ENERGY STAR Label for Buildings, of which the Target Finder Mr. Liu
noted is a tool, will serve you well for offices.  I believe it uses 1999
CBECS survey data.  In my recent experience what the Target Finder calls
"average" is a bit low -- twelve of the thirteen buildings I most recently
benchmarked were above average (and I haven't been doing my work in Lake
Wobegon).  Since the tool normalizes for weather, occupancy, and function
within building, among other things, I suspect that recent growth in server
room power intensity could be an explanation.  Others are welcome to
challenge me on this.

ORNL also has an office benchmarking site,
http://eber.ed.ornl.gov/benchmark/tools.htm, as does yet another LBL site,
http://poet.lbl.gov/arch/.  BOMA sells such data privately.

Depending what type of laboratories are of interest to you, try the LBL
Cleanrooms Web site, http://ateam.lbl.gov/cleanroom/, and the LBL 21st
Century Labs, Web site,
http://www.labs21century.gov/toolkit/benchmarking.htm, may be of use.

Finally you asked about pharmaceutical manufacturing.  The DOE Plant Energy
Profiler is a powerful tool for the Chemical industry benchmarking of which
Pharm is a subsection as classified by SIC.

Alec:

Energy Star has a on-line program called Target Finder, which is based on
energy performance data of commercial buildings. using this program, you can
find utility consumption for various buildings. It may be useful for you.

Following is the URL of Target Finder and a brief introduction of how the
performance data are obtained.
http://www.energystar.gov/index.cfm?c=target_finder.bus_target_finder

"The Energy Use Intensity generated by Target Finder reflects the
distribution of energy performance in commercial buildings derived from data
in the Energy Information Agency's (US Department of Energy) Commercial
Buildings Energy Consumption Survey (CBECS)1. The required data inputs were
found to be the primary drivers of energy use. The zip code is used to
determine the weather conditions that the building would experience in a
normal year (based on a 30-year climate average). The total annual energy
use intensity for the target is based on the energy sources typical in the
region specified by the zip code. For example, an Office Building in the
20902 zip code would be roughly 80/20%, electricity to natural gas. Users
may enter their own fuel mix."

Hi,

Does anyone know of published benchmark utility consumption studies for
office, labs, and possibly pharmaceutical manufacturing plants?

I'm looking for normalized utility usage (kWh/sf-yr, MBTU/sf-yr) for generic
buildings.

Any leads to websites, etc. would be appreciated.

 Sincerely,

Alec Stevens, PE, LEED AP
