San Antonio, TX | 726,000 Sq. Ft. | $325,000,000 | New Construction

LCCx was selected to provide Project Management on the LEED Silver Enhanced Commissioning for the major expansion of the Henry B. Gonzalez Convention Center project.  This project was awarded as a task order on the City of San Antonio’s On-Call Building Commissioning and LEED Monitoring Services contract. We worked directly with the City of San Antonio’s Energy Manager through the City’s Office of Sustainability.

LCCx was heavily involved in helping create the OPR (Owner’s Project Requirements).  LCCx participated in numerous design reviews of the energy using systems including the HVAC, Domestic Hot Water, and Lighting Controls.  LCCx paid particular attention to the BAS (Building Automation System) as furnished by Honeywell.   We conducted numerous design reviews of the SOO (Sequence of Operations) and the new graphic interfaces on the BAS dashboard.  We spent considerable time reviewing submittals for the above systems (all in conformance with LEED Energy and Atmosphere Credit 3 Enhanced Commissioning). 


This complex project involved a 726,000 S. F. expansion to the existing convention center which was nearly 50 years old.  The expansion had to meet more stringent energy codes so there was Demand Ventilation Systems, Dedicated outdoor air systems, single zone and multi zone AHU.  In addition, the entire chilled water loop was converted to a closed loop system from the City’s Central Energy Plant, formerly a single loop system.  In addition, the entire convention center was removed from the City’s hot water loop and the entire convention center was converted to individual high efficiency condensing boilers to furnish hot water for the AHU heating coils.
