Patrick Dempsey, PE, LEED AP BD+C, BEMP, recently wrote a piece for Consulting Specifying Engineer about standards building owners face regarding energy codes, and the effect they have on heating and cooling system selection. The piece features a case study from a confidential client with strict heating and cooling system-selection requirements.

According to Patrick, the most challenging projects for designers from an energy perspective are projects where the performance standard of the client far exceeds current code minimums, and requires detailed analysis to comply with the energy performance target. It’s important to monitor metrics including boiler efficiency, chiller efficiency and control requirements for heating and cooling systems. For air distribution systems, engineers need to determine whether it’s best to go with a dedicated outdoor air system or a more standard distribution system that handles ventilation and temperature control requirements.
