It’s hard enough to update the HVAC systems on a older building, but if it is the historical Northrop Auditorium (1929) it is doubly hard. Edward Clements writes about the issues the University of Minnesota faced updating the mechanical and lighting systems this building. In the current issue of Engineered Systems.
“Chilled beam terminal units were also used to provide a thermally comfortable environment while minimizing total system airflow in the back of the house, and a dual-wheel energy recovery AHU (Air Handling Unit) was used to deliver air to the space.”
In addition Clements writes about Displacement Ventilation, Atrium Smoke Control, and Lighting updates. There was a lot work require to reopen by April of 2014.
