While I'm not sure that I have any of the specific numbers that you
are seeking, I do have reasonably precise building-wide utility
consumption numbers. While these include office spaces and about a
dozen small, private labs, it is safe to assume that our 10,000 sq.
ft. clean room is the dominant consumer of all of these utilities.
Note: we don't directly pay for any of these utilities: they are
taken out of the ~60% overhead rate paid by all federally-sponsored
and non-Stanford research activity. The most recent month for which
I have numbers is March 2015 but that is probably a pretty typical
month.<br>
<br>
Chilled water: 154,562 ton-hours @ $0.6205 per ton-hour = $95,906.<br>
Electricity: 602,402 kWh @ $0.1384 per kWh = $83,372.<br>
Hot water: 620,484 kBtu @ 39.95 per 1000 kBtu = $24,540.<br>
Domestic water: 556,662 gal @ $11.29 per 1000 gal = $6,285.<br>
Waste sewer: 556,662 gal @ $6.14 per 1000 gal = $3,418.<br>
<br>
Total monthly building energy cost: $213,521. While I don't know
for certain, my guess is that our 10,000 sq ft clean room consumes
60-70% of most of the above categories for either
powering/heating/cooling the tools themselves or pushing 600,000 CFM
of temperature-controlled air through the space.<br>
<br>
As I indicated, we don't actually pay that directly, but it comes
out of indirect costs of 60% that are paid by all
federally-sponsored and non-Stanford research activity. Also, the
School of Engineering gets a baseline electrical allocation and does
pay for any excess usage beyond the baseline and also gets a
"rebate" for any amount under the baseline usage. That is the
incentive to save energy and will likely be extended to chilled
water, hot water, and domestic water usage in the near future.<br>
<br>
Note: our lab is also not charged for the monthly DI service
contact, maintenance of our CDA compressors, or maintenance of our
TGO sensors ... those are all deemed to be a facility cost and are
not charged directly to a research group or service center.<br>
<br>
I must confess that I am not familiar with the some of the terms on
your list: in particular, mechanical and electrical distribution
are new terms to me.<br>
<br>
Let me know if you have any further questions,<br>

<div>Dear Colleagues,</div>
<div><br>
</div>
<div>I would like to come up with a reasonably accurate estimate
of the infrastructure operating and maintenance costs associated
with our 6750 sq.ft. cleanroom. If you've completed such a study
in the past I would greatly appreciate hearing from you in
regards to the methodology you used at the time and any
references or rules of thumb that may have been useful to you. </div>
<div><br>
</div>
<div>Using the same terminology used by our own Plant Operations
group, the following are the variables I would like to include
in my study. Some of these seem vague to me personally but I
suspect this is likely due to the fact that this type of
analysis falls beyond my scope of experience. </div>
<div><br>
</div>
<div>-Building </div>
<div>-Central Plant </div>
<div>-Mechanical distribution </div>
<div>-Electrical Distribution</div>
<div>-Grounds</div>
<div>-Electricity</div>
<div>-Heat</div>
<div>-Water</div>
<div><br>
</div>
<div>In addition, I would also like to hear from the community as
to whether their respective administration expects their fab
operating revenues to cover these particular infrastructure
costs. Specifically, I’d like to know whether you are charged
for these types of costs by your internal plant operations or
finance groups.</div>
<div><br>
</div>
<div>Thank you very much for any insights.</div>
<div><br>
</div>
<div>Best regards,</div>
<div>Vito</div>
