This quickly expanding research university had embarked on a multi-phased expansion project for its health sciences departments. This newest building, dedicated to biological-based research, required strictly controlled spaces for a variety of research activities, necessitating multiple mini-environments contained within one building envelope.


  • Cooling, heating and humidity for a VAV system with +/-2 degree F, and +/- 10% RH for 2000 sf [A]nimal [C]are [F]acility Supply air needs were relatively small, but designed to deliver the correct required air quality for the animal area specifications while adjoining areas posed infiltration issues

  • Pressurization for mixed use floor space with offices, mechanical space, waste containment, gowning and ACF areas

  • Dedicated filtered exhaust for AC Corridors.

  • HEPA filtered supply air for AC Corridors and areas.

  • Selected and engineered CRAC’s for cooling a 4500 sf data center with N+1 cooling built in.

  • New fire protection design including design for gas suppression system in the data center.

  • Lab gas piping design and routing for CDA, NG, CO2, VP. Compressed dry air compressor sized for 600 gal tank capacity and 146 scfm of flow. 100 scfm capacity vacuum pumps were sized and distribution pipe routed to support the facility lab spaces.

  • Lab water and clean steam engineered to support cage wash, sterilizer and bench needs.

  • Detailed riser diagrams with drop component requirements and material standards.

  • Detailed exhaust requirements for fume hoods, cagewashers and biocontainment cabinets.


  • ACF designed with a commitment to the required environmental specifications for the animals. Biocontainment safety cabinets, lab benches and cagewash facilities designed to NIH and local standards/codes. Designed hood performance to ANSI 29.5 and ASHRAE 110. Distribution air adhered to ANSI/AIHA Z9.5 in lab spaces.

  • 30,000 sqft of mixed use space designed to control mini-environments such as animal care and quarantine areas. Adjoining office and common space was pressurized to avoid cross contamination and testing corruption.

  • Critical lab and animal care environments were carefully designed to promote consistent working conditions including lab process piping coordination, strict adherence to Rh and temperature specifications, and exhaust requirements promoting a contained environment within the building
