Resources
Public Tools
There are a number of tools tailored specifically to hospitals and healthcare facilities that should provide a strong resource foundation to begin implementing sustainable practices without compromising your institution’s strict regulatory and safety requirements.
We’ve compiled a comprehensive list of these tools, categorized according to the Planning Process Step where they will be most useful to you and your team.
Considerations
Issues and obstacles are inevitabilities in any project, large or small. This section was created to provide an overview of many of the issues that other hospitals have encountered over the course of their decarbonization initiatives. Consider it less a problem-solution resource than a list of things to be aware of as your planning and implementation processes proceed.
Glossary
Part of your decarbonization journey is learning the language. We’ve complied a glossary, based upon the final published ASHE glossary.

Considerations
Issues and obstacles are inevitabilities in any project, large or small. This section was created to provide an overview of many of the issues that other hospitals have encountered over the course of their decarbonization initiatives. Consider it less a problem-solution resource than a list of things to be aware of as your planning and implementation processes proceed.
General
Each building sector experiences its own unique set of challenges when it comes to implementing decarbonization projects. This short list, however, comprises a set of high-level considerations that are common to all. In your planning phase, it’s wise to be aware of:
- Capital constraints and difficult return-on-investment evaluations.
- Utility electrical grid decarbonization timelines and coordination.
- Electrical grid reliability concerns as the utility electrical grid decarbonizes with zero-emission generation solutions.
- Workforce training to operate and maintain new low-carbon HVAC system solutions.
- Technology gaps to achieve replace-in-kind HVAC solutions with existing HVAC system infrastructure.
- Building infrastructure limitations for electrification solutions for HVAC systems.
Building Code Conflicts
Resilience
Resilience is a consideration will be referenced often over the course of this guide. Particularly for healthcare facilities, maintaining rigorous, dependable 24/7 energy will always be a top priority. The following considerations will be foremost in the minds of every healthcare facility that undertakes decarbonization:
- Uninterrupted patient care throughout implementation and operation of new low-carbon HVAC system solutions.
- Building code requirements associated with maintaining safe indoor environments.
- Operational safety factors associated with back-up equipment and energy sources to maintain resiliency.
HVAC
Every HVAC infrastructure upgrade plan should start with a holistic evaluation of your facility to ensure your team has explored every opportunity to increase efficiency, recover heat, and electrify. Consider the following structure as a high-level blueprint for your HVAC decarbonization strategy. It can be useful no matter where you are in the carbon reduction planning process:
- Tier 1 – Optimize controls to reduce and conserve energy in your existing HVAC system(s).
- Their 2 – Replace equipment and systems that have reached the limit of their useful life.
- Tier 3 – Install new low-carbon HVAC solutions

Glossary
The final list of definitions is contingent upon the final guide. All definitions will be developed using ASHE’s glossary.
