UMASS W.E.B. DU BOIS LIBRARY
AMHERST, MASSACHUSETTS
CHALLENGE AND OPPORTUNITY
The W.E.B. Du Bois Library is a 26-story, 310,000 ft2 building that houses special collections, offices, computer labs, media storage and book stack areas. The facility is served by over 20 AHUs, two chiller plants, 14 heat exchangers and 60+ pumps. The building frequently had occupant comfort complaints and pressurization issues.
B2Q was contracted to conduct an investment-grade EBCx study and turnkey implementation services including Engineering, sub-contractor management, CxA, M&V and utility incentive. The EBCx study identified over ten energy-savings and twenty-five performance-improvement measures to address the pressurization and occupant comfort issues.
MEASURES
Installing air curtains, weather stripping and revolving doors to improve building pressurization
Pneumatic to DDC conversion to improve equipment control and reliability
Conversion from constant volume airflow and pumping control to variable volume
Re-balancing outdoor air systems and adding sophisticated DCV sequences
Significantly improved building pressurization control
Over 1,000,000 kWh annual electric savings and 4,000 Mlbs annual steam savings $200,000 in avoided annual energy costs
Improved equipment control, reliability and visibility after converting to DDC
