To reduce the university’s energy costs while avoiding the capital expenditures needed to expand the existing energy plant’s cooling capacity, the design and construction team delivered a 3.5-million-gallon chilled water, thermal energy storage tank in May 2020. Under its current rate structure, the university pays local utilities more during peak times. The TES allows 25,000 ton-hours of compressor load to be generated during off-peak times, then discharged during on-peak hours.

虽然设计要求将166个H桩安装到45英尺的深度,但是所需的地下土壤条件需要将许多桩驱动到65到70英尺之间的深度。每个延伸都需要由工程师批准的现场工程解决方案记录。延伸延伸需要部分地去除现有桩,焊接在额外的钢长度上并重新安装。

具体工作,包括3-ft-thick钢筋pile cap and tank base, was completed with zero deficiencies or rework. The tank base was poured in one continuous 600-cu-yd pour, involving 60 concrete truck deliveries that had to navigate around the occupied campus.

该团队在现有建筑物之间的有限空间中占据了有限的空间,该团队设计了预制的网站。如果没有足够的划仓区域,必须计划稳定的立即面板输送,起重机镐和站点焊接以支持装配过程。

调试中央植物之间需要复杂的协调 - 这耗尽不间断和新建。要将TES系统集成到现有的冷却设备中,该团队必须使用校园冷却需求和TES罐的再充电来平衡冷却器厂冷却和TES冷却发电。

The completed project quickly realized significant energy cost savings to the university, with data from the first six months of operation suggesting it could see annual savings of at least $300,000.
