HVAC Systems: Effective Design vs. Operations

Energy efficiency continues to be a fundamental metric as it relates to design, construction, and operation in healthcare facilities. Efficiency improvements often require low capital investment and are easy to implement, while others require significant investment and a phased approach. This presentation will explore opportunities to benchmark and improve your facility’s energy performance through capital projects and initiatives to turn your healthcare facility into a top performer.

When considering facility expansion or renovation, balancing project budget with HVAC system selections can be challenging. This presentation will discuss several of the common HVAC system options used in healthcare facilities.

The presentation will close with a case study of a recently completed expansion/renovation project that implemented several energy-conscious strategies using traditional HVAC systems, resulting in a significant increase in the Energy Star Rating for the campus.
