Coordinate Campus Update: Morris: • Electrical

– Projects • Reviewing time of day pricing tariff • Studies show up to 19% reduction in electrical for residence halls • Partnering with Grad students in Electrical Engineering to develop

control strategies for academic buildings – Research

• Working with private Company and UMM Computer Sciences to build web/app development of real time mobile device energy desktop

• Thermal • Running both corn cobs and natural gas. Burned approximately 300

tons of cobs in December

Coordinate Campus Update: Crookston: Undergoing a compliance study and needs assessment on coal fired heating plant. Listed below are some pertinent points in regards to this undertaking:

– What steps need to be taken or modifications made to the current plant to bring the plant into compliance with the current boiler MACT standards

– The first part of the study will focus on mercury emissions and carbon monoxide emissions in the exhaust stream from the coal fired boiler to insure they are under the applicable limits by March of 2014

– What other modifications or improvements are needed to be undertaken to position the Crookston Campus to meet the steam generation and heating needs now and the foreseeable future

– The President’s Climate Commitment initiative will be a cornerstone of this critical activity

– Projects are a joint effort with members of Crookston Facility Management, Twin Cities Energy Management, UMN CPPM along with personnel from Burns and Mac Donnell Consulting Engineers

Coordinate Campus Support: • UMore Park/SAFL

– Wind power project (Design review, commissioning and contracts)

• Crookston – Heating system analysis; production, distribution, fuel sources

• Sustainability • Climate Action Plan • Energy Conservation

• Cost Effective

Twin Cities Campus Principles:

• A new broad based and significant utility master plan was completed in June, 2009

• Secondary plans were detailed for: – Utilities for the Ambulatory Care Clinic – Biomedical Discovery District utility needs – Knoll utility routing for chilled water and power

• A significant update to original plan completed for Minneapolis steam requirements and power production in February, 2011

• Our plans are under constant review!

Utility Master Plans:

Reliability – Steam:

Holiday Steam Demand Control Experiment Reliability – Steam:

• Combined Heat and Power Plant – Update – Recommended in Governor’s Bonding Bill – Engineering and Architecture Firm selected

and began work to design the Plant

Reliability – Steam:

• What we have done – 5,000 feet of 14” steam line added – Replaced 1,000 feet of condensate return

• What we are doing – Rebuilding a drop shaft in Minneapolis

• What we plan to do – Improve ventilation in the deep tunnels and use

the heat as an energy source for buildings – Rebuilding more tunnels in St. Paul – Rebuilding another drop shaft in Minneapolis

Reliability – Steam:

• Distribution upgrades completed: – New connection completed to run from 4th Street to

Fulton Switch Stations – Duct bank completed to feed the additional loads in

the Biomedical Discovery District

Reliability – Electricity:

• What we learned last summer: — Light rail and the weather stressed our

systems to the max — How we plan to resolve the constraints:

• Adding another feeder from Xcel Energy’s Terminal Sub-Station

• The addition of our Combustion Turbines in Old Main • Distribution to Fulton and 4th Street Switch Stations • Behind the meter

Reliability – Electricity:

• Past Year Accomplishments: – Health Sciences:

• Installed 1100 tons of steam-driven refrigeration capacity

• Implemented year-round chilled water operations in Health Sciences district

– East Bank: • Expanded east bank chilled water distribution. Annual

savings gained: – Bell Museum: $46,183/year – Nolte Center: $8,373/year – Shepard Labs: $141,066/year – Civil Engineering: $63,532/year – Total Annual Savings from above four projects: $259,154/year

Reliability – Chilled Water:

• Past Year Accomplishments: – West /Bank:

• Developed plans to retire the last three stand-alone cooling systems. When implemented, this will reduce annual energy and maintenance costs by $142,000 annually

– Biomedical Discovery District: • Developing the district chilled water system. Annual savings versus

stand alone systems will exceed $1 million per year

– And more….

Reliability – Chilled Water:

• Next Year’s Plans: – Implement distributed plant operations in the new BDD

district chilled water loop – Complete cooling replacement cost studies for:

• 717 Delaware (19 years beyond useful life) • Bierman Athletic Complex (17 years beyond useful life) • WBOB (reaching end of useful life, but supports mission critical

business and is showing significant signs of aging due to considerable deferred maintenance)

– Expand east bank chilled water production capacity and distribution to connect:

• Physics and Nano • U Rec Center Expansion • 4th Street Housing • Eddy Hall Renovation

– Update the master plans

Reliability – Chilled Water:

Water and Sewer Stewardship Process Improvement

– Storm water modeling for the Biomedical Discovery District was fully developed. Projects built in that district are now evaluated not only for conformance to the University's storm water requirements but also to determine the system capacity impacts. St Paul campus storm water modeling will begin in early 2012.

– A condition assessment of the St Paul water distribution system was performed on the oldest segments of pipe on the campus. The goal of the assessment is to find small leaks and/or capacity constraints in the system to target rehabilitation of the main. This type of targeted approach uses asset management principles to identify the best use of resources for the most life cycle gains.

– Continued to improve the GIS inventory map of the Civil Utilities. Migrated the data to the centrally supported Oracle database. Began to field-collect data for inspections. Began to publish controlled access maps online to project consultants. Began adding drainage area information for the purpose of hydraulic modeling. Using GIS is a highly efficient way to manage these assets.
