Hockey Rink Rooftop Condenser Structural Supports

This project involved replacing rooftop chiller condensing units servicing not one, but two hockey rinks. You can imagine the amount of energy required to produce enough cold to keep two ice rinks well below freezing temperature. So, replacing the condensers with modern, gas-fired compressors will return the investment quickly.

These two compressors are heavier than the existing, so we performed an analysis of the existing steel roof framing to see if it was adequate. Fortunately, the roof framing was originally designed to support a high amount of snow drift-loading with higher roof surrounding it, so it was adequate as-is to support the new units. We only needed to design new steel beams and columns to transfer the weight of the units to the steel framing below.
