376 Science Building (College)

Science buildings include areas for lectures, demonstrations, audiovisual presentations, laboratory work and study and some administrative and stage areas. Typically, there is also an area designated for storage of materials and equipment. The laboratories have both AC and DC variable voltage and plumbing in the work areas.

Since science buildings have higher requirements for heating, cooling and ventilation, use component 617 (Complete HVAC) for HVAC costs.

The following are not included in the costs: Lab equipment.

Availability of Elevators by Area for this occupancy: No
