The campus has one central plant distributing heating hot water through a common piping system. Refer to Appendix II for a site plan showing the existing conditions of the campus thermal piping routing and sizes. The current campus heating capacity is 17,300 MBH (output) with 11,900 MBH (output) of firm capacity. The current campus peak cooling demand is 10,000 MBH. Boiler efficiencies are assumed to be 90% for the purpose of this analysis. The current heating equipment is listed in Table 6 below: Table 6: Existing Campus Heating Equipment Boiler Location Age Capacity (MBH) Boiler 1 (Cleaver Brooks) Central Plant 7 Years 3,300 MBH (Input) Boiler 2 (Cleaver Brooks) Central Plant 7 Years 3,300 MBH (Input) Boiler 3 (Cleaver Brooks) Central Plant 7 Years 3,300 MBH (Input) Boiler 4 (Cleaver Brooks) Central Plant 7 Years 3,300 MBH (Input) Heat Pump Central Plant 3 Years 5,400 MBH (Output) Total Capacity 17,300 MBH (Output) Firm Capacity 11,900 MBH (Output) As the campus continues to grow more buildings will be constructed and demand on the heating infrastructure will increase. To estimate the new heating loads, load factors for each building were utilized. These load factors as shown on Table 7 and are based on historical data for similar buildings. Table 7: Heating Load Factors Building Type BTU/SF Support 15 Housing 20 Academic 15 Research 30 Tables 8, 9, and 10 below breakdown the growth in heating demand between phases 1, 2, and 3 of the campus expansion, respectively. The “Key” assigned to each building represents the name of the building on the master plan site plan. The increase in cooling demand for the expected campus growth is about 19,160 MBH total.

Refer to Appendix I for reported daily campus max/min system demand and flowrates. Based on the growth described above and the collected campus data, the new campus heating demand will be 29,220 MBH. This requires 17,820 MBH of heating capacity (output) to be added to the current firm capacity (output) of 11,900 MBH. Additional heating capacity will be provided by expanding the existing central plant in campus expansion phases 2 and 3. The existing central plant is designed to be expanded to the south. When this expansion is complete, an additional 17,820 MBH of firm capacity will be available to the campus. Additionally, new heating hot water piping infrastructure will be necessary to serve the campus growth in the SouthEast direction towards University Blvd. Refer to Appendix II for site plans of the additional heating hot water piping necessary for campus expansion at each phase of development.
