MECHANICAL UTILITIES 99 Campus Master Plan Update 99 C/ APPENDIX A. EXECUTIVE SUMMARY The Texas A&M International University master plan projects the campus to grow by approximately 1,200,000 square feet by the year 2040. Most of this growth will be outside of the existing campus thermal infrastructure with some growth internal to existing site infrastructure. The growth is projected to require an additional 3,370 tons of campus cooling demand. Heating demand will increase by 19,160 MBH. Prepared by Texas Registered Engineering Firm F-2113 March 2023 The current campus cooling demand is approximately 2,300 tons. The central plant is located adjacent to the Kinesiology and Physical Plant buildings and consists of four 1,000 ton chillers. The current total cooling capacity is 4,000 tons with a firm capacity of 3,000 tons (firm capacity is equal to the total capacity with the largest piece of equipment not in service). The current campus cooling firm capacity exceeds the cooling demand by approximately 700 tons. Based on the planned campus growth, the campus cooling demand will increase to about 5,850 tons. An additional 3,000 tons of cooling capacity will be needed to meet the future demands and provide firm capacity. The campus distributes heating hot water from the central plant to buildings for comfort heating. The current campus heating demand is estimated to be 10,000 MBH. The current campus heating capacity is 17,300 MBH with a firm capacity of 11,900 MBH. The campus growth will increase heating demand by approximately 19,160 MBH for a total heating demand of 29,160 MBH. The current campus heating firm capacity exceeds the heating demand by approximately 1,900 MBH. An additional 17,850 MBH of heating capacity will be needed to meet the future demands and provide firm capacity. To meet the future demand, the central plant shall be expanded to the South in order to house the additional cooling and heating equipment necessary. The campus is projected to mostly grow in a South East direction from the location of the central plant. This area of the campus is currently without thermal infrastructure, which will be needed to facilitate campus growth. For a summary of the additional site thermal infrastructure necessary, refer to Appendix II for a breakdown of additional piping required per developmental phase.
