Selecting an HVAC system type for any building can be a simple or complex process based on the purpose or function of the building and the guiding parameters for the project. Projects can run the spectrum from being straightforward applications such as a shipping warehouse that can typically be driven by low initial cost or reduced maintenance concerns, all the way up to complex applications such as hospitals and laboratories that carry an increased level of demands, a variety of required thermal conditions, and a requirement for reliability. While most design situations might already have a preferred HVAC option based on the project type or building owner preference, these may not provide the optimum solution for a specific project. That optimum solution is a high-performance HVAC system.
