Chilled Beam Retrofit in the Rotary Building

Big Ten & Friends Mechanical and Energy Conference – Hosted by IUPUI

Eric Broemel, PE, CEM with co-presenter Holly Thomas, PE, IUPUI Energy Engineer

October 1, 2018

The presentation focused on the design and construction of the Rotary Building on the IUPUI campus. The building was recently renovated to accommodate the IU School of Medicine. Achieving LEED Silver certification, the renovation included the extensive reprogramming of the space, the addition of a central communicating stair, the improvement of the building envelope, as well as entirely new mechanical and electrical systems throughout the building.

Schmidt Associates received an ASHRAE Design Technology Award for this project. Through the submission process for the award, the actual energy usage of the building was recorded after construction was complete. It was discovered that the usage was significantly larger than predicted by the LEED energy model. Through follow up and further adjustment of the of the HVAC systems, Schmidt mechanical engineers worked alongside IUPUI staff.  Together they were able to correct the issues and bring the usage in line with expectations. The presentation highlighted the issues that were uncovered and the actions that were taken to resolve them.
