Results of CC Follow-Up in the G. Rollie White Building

Abstract

An investigation into the increase of energy consumption of G. Rollie White Coliseum was part of the persistence project[1], which investigates the savings in energy consumption of ten buildings that were commissioned by the Continuous Commissioning (CCSM) group at the Energy Systems Laboratory (ESL), Texas A&M University (TAMU). The CC process was conducted between 1996 and 1997 under direction of and in cooperation with the TAMU Physical Plant Energy Office. Total savings for the ten building are $4,255,000. Most of them had small savings degradation (or increased savings), but the degradation of savings of G. Rollie White Coliseum was larger than all the other buildings. The CC follow-up activities on the investigation into the increase of energy consumption of G. Rollie White Coliseum included energy consumption and HVAC system operation data analysis, measurement on HVAC systems, and examination of the control program. HVAC hardware problems, HVAC operation problems, and control program problems were found. By fixing HVAC hardware problems, correcting HVAC operation, and modifying control program, the indoor air temperature and humidity are now under control and annual energy savings of about $36,300 more than the initial CC are being achieved.
