Shah Smith & Associates provided mechanical, electrical and plumbing engineering coShah Smith & Associates, Inc. provided MEP engineering services for this MD Anderson Cancer Center Houston Area Location.

This 210,000 sq. is an outpatient cancer center which offers diagnostic, MRI, CT imaging, specialty pharmacy(USP 797 and 800 compliant), linear therapy, infusion, radiation oncology (linear accelerator and high-dynamic-range imaging), endoscopy, interventional radiology, lab and exam, women’s’ health mammography, lab and diagnostic, general exam and in house full diagnostic lab services. 

The mechanical systems consist of two air-cooled chillers and N+1 redundant pumps with variable primary flow. A process cooling loop with two 100% redundant heat exchangers and pumps provides process chilled water to cool imaging equipment throughout the building. Gas fired condensing heating hot water boilers and pumps with VFDs provide N+1 redundancy for the entire heating system.  Pre-treatment outside air handlers with energy recovery wheels will supply air to building VAV air handler system with VAV terminal boxes containing hot water coils. Air handling units are manifolded to provide redundancy within the system. The IR Procedure Suites and supporting areas are served by a 100% redundant air handling unit system. The pharmacy area is served by a dedicated 100% redundant air handling unit system and exhaust fans.

Domestic water is supplied to the building with pumps for distribution. A water softener is provided for soft water supply to the natural gas condensing water heaters and hydronic boiler make-up supply. The water heaters have N+1 redundancy. Natural gas is routed to emergency generators located outside of the building on site, domestic water heaters, and hydronic boilers. Medical compressed air and vacuum systems are located in the penthouse for central distribution throughout the building. Central NFPA 99 compliant automatic switchover manifolds are provided for Oxygen, Nitrogen and Nitrous Oxide supply to the IR Procedure Suites and supporting areas.

The building is served electrical power from a pad-mounted transformer from Entergy serving switchgear in the building.  A 500kW natural gas generator serve essential electrical system needs through automatic transfer switches (ATSs).  ATSs separate branches between life safety, critical, and equipment branches with multiple critical branch and equipment branch ATSs to separate loads within the building.  Networked lighting controls are provided in the building, and all lighting is LED.  Power management software provides electrical system status back to the main campus facility operations center for remote monitoring capability.
