University of Virginia: Campbell Hall

Background

Campbell Hall has been home to UVA’s School of Architecture for more than 50 years. The building serves as the School’s center, hosting lecture halls, labs, and galleries.

Since its completion, the building has been renovated to reflect the needs of students and the environment. Sustainability has grown to become a focus and driver of the School of Architecture. In 2011, Campbell Hall completed a chiller plant optimization project, followed by a significant HVAC controls upgrade from pneumatic to DDC through much of the building for a total project cost of $330,000.

The School of Architecture wanted to further their sustainability efforts by improving efficiency more through the following project. The changes to the physical building reflect the School’s commitment to efficiency and optimization, for both their students’ work and their facilities.

Solutions

Campbell Hall’s continuous upgrades improve operations and fuel the creative spirit of the school. For this $460,000 project, upgrades included new HVAC controls, LED lighting fixtures, and installation of new variable frequency drives, all which improved occupant experience and comfort while reducing maintenance.

Upgraded HVAC controls enable HVAC to better match occupant needs. Specific upgrades included:

  • Retro-commissioning of existing HVAC systems and implement improved logic and functional performance tests;
  • Converting constant volume HVAC systems to single-zone variable air volume systems;
  • Implementing demand control ventilation (DCV) with airflow measuring stations and VFDs where applicable; and
  • Performing ventilation optimization throughout the building (excluding Fiske Kimball Fine Arts Library).

Additionally, variable frequency drives were installed on fans and pumps to allow the fans and pumps to use less energy when demand was lower.

LED lighting upgrades were done throughout the building, including in Fiske Kimball Fine Arts Library.  Also, HVAC system controls enhancements include interfacing systems with the existing Lutron lighting control system which along with the installation of new HVAC CO2 sensors, now allow lighting and HVAC systems to optimize ventilation requirements by responding to occupancy needs.

Other Benefits

The improvements to Campbell Hall enhance the building’s operations and efficiency. Energy costs have been reduced, and 3,000-4,000 metric tons of carbon emissions have been prevented per year. The project upgrades resulted in improved reliability and more accessible monitoring, allowing for longer service life, reduced risk of unexpected equipment downtime, and decreased maintenance and nuisance complaints. Further, improved lighting quality and controls improved occupant comfort.
