Area: 3,000 GSF
SBEC was the prime consultant for this project.
The mechanical system featured redundant ventilation and heating systems.
The air handling units contained HEPA filtration, heat recovery coils,
hydronic heating coils, DX cooling coils, variable frequency drives and
direct injection humidification.
Each room was equipped with independent pressure control to meet the
special ventilation requirements for animal holding cages. A number of
spaces were provided with special humidity and temperature control to
serve cold-blooded animals. Condensing boilers were used to heat the
facility. Exhaust was designed with high plume discharge to minimize
animal odors in a congested campus setting.
The electrical design utilizes an existing backup generator to provide
a reliable source of power. SBEC provided new normal and backup power
distribution panels.
Limited space for new equipment required use of innovative design practices
to place the equipment within an existing mezzanine space.
