Energy and Carbon Master Plan

In 2016, RMF prepared a Utility Master Plan for the College to evaluate the capacity of their existing infrastructure to handle a 20% increase in campus square footage. In 2021, RMF was selected by a competitive process to carry out a more comprehensive Energy and Carbon Master Plan that would convert the campus heating system from steam to low temperature hot water (LTHW). The team evaluated multiple potential generation plant locations and equipment portfolios and conducted geo-exchange test bores to explore the viability of a geo-exchange heat pump system. In parallel, RMF engineers conducted campuswide energy audits and developed an energy conservation plan that prioritized high-impact ways to reduce energy demand. RMF was also hired to design a full campus electrical upgrade to increase voltage and prepare for the transition to electric heating.

Williams College had the following five primary objectives:

Forecast the campus’s energy purchasing requirements, capital investment, operating costs, and greenhouse gas emissions This case analysis will be referred to as the Business-as-Usual Case.

Validate the feasibility and expected performance of a new borehole thermal energy storage (“BTES”) system and/or an aquifer thermal energy storage (“ATES”) system

Develop a detailed investment plan that specifies the infrastructure needs, implementation phasing, operating requirements, and upfront and ongoing costs.

If the result of the Decarbonization Case is a recommendation to implement a low-temperature hot water distribution network on campus, develop a detailed investment plan.

Compare lifecycle costs and greenhouse gas emissions (Scope 1 and Scope 2) outcomes between the Business-as-Usual Case and the Decarbonization Case through 2035.
