Description
Access to the complete library of ASHE monographs and discounts on all publications are included in ASHE membership. Visit ashe.org/ashe-membership! Electrifying Heat in an Existing Hospital is a groundbreaking and comprehensive analysis conducted in partnership with Providence St. Peter Hospital that establishes the feasibility of electrifying the existing hospital building’s thermal load. While previously there has been extensive guidance for decarbonizing new hospital buildings, little information was available about the decarbonization of an existing hospital building. Additionally, there was speculation about the feasibility of electrifying the thermal load and decarbonizing an existing hospital from a technical and financial perspective. This case study, written by the American Society for Health Care Engineering, shows: - It is technically feasible to electrify the Providence St. Peter Hospital building’s thermal load:
- The project will need to be done in phases over approximately 10-15 years.
- Decarbonization planning needs to begin early.
- The building must be optimized concurrently with other decarbonization planning, which includes ventilation, energy conservation measures, the building envelope, etc.
- It is financially feasible to electrify Providence St. Peter Hospital’s existing building:
- Electrifying the thermal load would cost around $100/square foot.
- Full decarbonization includes factors beyond the thermal load, however decarbonizing the thermal load has been seen as the most difficult and has the most naysayers. Other systems to decarbonize include:
- Deactivating piped nitrous systems.
- Removing desflurane from drug formulary.
- Electrification of the transportation modes.
- Less waste to the landfill.
- Purchasing renewable energy.
The book provides a detailed outline of the steps one hospital is taking to achieve this feat. Yet, to be clear, this publication is not intended to be a playbook for electrifying any given hospital, nor is it meant to be a benchmark by which other hospitals pursuing this goal should be measured. The path to complete electrification is an extremely complex and bespoke process. Each electrification plan must be tailored to the specific goals of a given health care facility or system as well as regulatory requirements that govern that facility and the needs of the communities it serves. That said, this case study does serve as a success story meant to inspire and demonstrate that this feat, which not so long ago seemed impossible, might be, in fact, within reach. Read the companion piece, How to Prepare for a Decarbonization Study, to learn how health care executives and facilities teams can initiate a decarbonization study and start planning (and budgeting) for a transition to clean energy.
