Utility Planning For North Campus Upgrades

Area in and around Cook Physical Science Building

A Conceptual Plan…….

Why Is This ImportantThis Is Conceptual But Presenting A Long Term View Of

The Utility Upgrade Possibilities When We Design And Build The Cook Science Expansion

Do not want to miss out on the opportunity to solve many issues while planning for Cook

We need to do many of the upgrades any way Prepare for future projects in and around Cook Provide robust utility system for reliability, availability

and maintainability Most likely going to Air Condition Williams in the

future if renovated Has the potential to save

Some Deficiencies In And Around Area

Undersize and old piping sections Have to relocate piping in order to fit

building on East side Chilled water system capacity will be

depleted when Plant Science, Marsh, and Billings, Votey and Kalkin are hooked up.

Need cooling capacity for Williams, Cook 1, Cook 2

Better to send out lower pressure on campus

Some Opportunities Generate electrical power maybe 2MW Provide chilled water to Cook and Cook 2 Provide chilled water to Billings Provide chilled water to Williams Hall Distribute steam at a lower pressure Use back pressure turbine to reduce steam pressure Use daytime chilling capacity to store chilled water or ice at

night off peak hours Use heating and chilled systems as part of the engineering

curriculum Use excavation to maximize utility and energy systems in

and around Area This is the “green thing” to do for the future Build in redundancy for reliable utility distribution

Some Benefits Maximizing the use of steam pressure Historic building air conditioning Real time, real life engineering and economics study-

relate to theory with adjacent to/ or in new science building……..

We will need more chilled water than our plant can deliver when Cook buildings are initiated

Back feed to Given provides steam redundancy on distribution including CBW and Converse…..

If sized correctly steam can power up HSRF chiller to provide summer load for turbine generator set.

Do we need more air conditioned “Bed Space”….? We have infrastructure for this type of system

Engineering School and Other Teaching Thoughts

Thermo Dynamics Vibration studies Fluid Mechanics Material selections and metallurgy Theory of machines and rotating equipment Heat Transfer Many other courses and programs could utilize systems. Real time data used for study Real equipment available for students and faculty to use in

studies. Use the tens of millions of dollars investment for the study

of engineering Economic analysis of fuel use and energy consumption Other cool stuff..

If We Don’t Do This We will have to replace old deteriorated

steam lines anyway on East side of Cook and north side of Cook by Votey (see Pictures)

We will eventually air condition Williams Waterman, and tie our central system into Votey, Kalkin and Billings,

We will spend more on operating costs We will not maximize the use of existing

systems.

Some Steps To Take

Replace/Relocate line on east side of Cook Add chilled water lines to Cook Add chilled water lines to Kalkin/Votey Connect LP Steam to CBW to feed Converse and possibly Given Investigate night time storage of chilled water or ice Possibly relocate chillers to assist in chilled water plant

operations Connect Billings, Williams and loop back to Old Mill with LP

steam Add Topping Turbine to Cook or Central Plant with exhaust

steam powering LP loop Install electrical distribution system to power Cook, Cook 2, Old

Mill, Library, Davis, Votey, RTT, Kalkin “Engineer the entire area for the future Install Electrical Distribution network..

Chilled Water and Steam And Need

For Electrical Distribution

Conclusion This concept needs to be studied for cost, economic

feasibility, life cycle, viability.

I think it is more palatable than a full blown 5Megawatt Cogeneration system

Up to 2MW may be OK with BED

We need to do some of this anyway let’s do it in a systematic, long term way.

It would be awesome for the Engineering School to have some of these systems as part of their learning curriculum

Conclusion
