Poindexter Hall – Mississippi University for Women

Originally constructed in 1902, Poindexter Hall stands as one of Mississippi’s oldest concert halls and is subject to Mississippi historical requirements. The renovation of this four-story facility consisted of a full replacement of the HVAC system and lighting controls. The replacement HVAC system consisted of two large single-zone air handling units to condition the main theater/symphony hall, a single outside air unit to provide ventilation to all spaces, and variable refrigerant vertical heat pump fan coil units.

The VRF heat pump fan coil unit system utilized branch circuit controllers to allow for simultaneous heating and cooling for the heat pumps on each controller. The controllers were then connected to outdoor units to remove the excess heat of the system. The VRF system was controlled by a separate control system which was integrating into the existing campus building automation system. The lighting controls for the facility were updated to included dual technology occupancy sensors and dimming controls to enhance the energy savings of the new high-efficiency lighting fixtures.

Added Value through CxGBS® services:

During design phase reviews, CxGBS identified the following issues and tracking them to resolution:

• Membrane waterproofing was not appropriately lapped in architectural design details.
• Architectural design details created thermal bridging between exterior and interior heated spaces, allowing possible condensation inside the building and excessive heat transfer.
• Design guidance has also been provided by CxGBS to optimize demand-controlled ventilation strategies for appropriate spaces in the building.
