5. Recommendations and Phased Rollout Priorities
Implementing campus-scale heating electrification demands a structured ranking mechanism that coordinates building fabric readiness with available thermal sources. High-temperature distribution loops connected to legacy gas boilers present immediate integration challenges when transitioning to low-temperature thermodynamic cycles [2]. Consequently, prioritization must favor building clusters where hydronic emitters can operate at lower supply temperatures without compromising occupant comfort. Dual-source systems and wastewater-source ambient loops provide viable operational pathways in complex urban layouts where land availability restricts extensive borehole arrays [1], [3]. Evaluating facilities based on proximity to auxiliary heat sinks, current envelope insulation quality, and local sub-station electrical head-room ensures that initial capital outlays achieve significant carbon abatement while avoiding grid overload [2], [3]. Facilities with heavy continuous base loads, such as centralized athletic complexes or wet laboratories, should be staged alongside compatible ambient loop networks to maximize seasonal performance coefficients [1]. This layered decision rubric allows campus facilities directors to deploy capital in clear phases, securing rapid early decarbonization gains while preparing older structures for deep envelope retrofits.
