When feasible, on-site renewable energy systems may also be incorporated.
•
The Standards have been developed specifically for the medical office buildings, ambulatory surgery centers, and smaller feeder fit-out sites.
•
The primary focus is new construction however it also addresses considerations for anticipated fit-out projects (medical office).
The intent of the Energy Performance Standard is to provide project teams contracted for the Ambulatory 2.0 project the recommendations, strategies and supporting resources needed for achieving optimal energy performance with the potential of net-zero emissions depending on the implementation of renewable energy systems, clean energy purchase contracts, and environmental offsets.

The content provided in this Standard is intended to serve as guidelines and parameters to be followed by project teams to align with Partners’ energy policies, objectives, and goals. Project teams are expected to comply with the requirements and/or demonstrate the process used to evaluate the design parameters with respect to the requirements. In circumstances where the requirements are not achievable, a thorough analysis should be provided to demonstrate the process used and rationalize the parameters which may exist that impede compliance.
