Calculations
American Institute of Architects, GUIDELINES FOR PLANNING AND DESIGN OF
BIOMEDICAL RESEARCH LABORATORY FACILITIES 1999
C.7.10.a Complete design load calculations and a moisture control study shall be
prepared for each space within a design program and presented in similar format to
that outlined in the latest ASHRAE Handbook of Fundamentals. Heating and cooling
load calculations are required for all projects to facilitate review and to provide a
reference for system modifications. Individual room calculations shall be generated
and summarized on a system basis and presented with a block load to define the
peak system load. Load summary sheets shall indicate individual rooms with area,
design air quantity, L/s per m
2
, air changes per hour, and corresponding return or
exhaust air quantity. Calculations shall include but not be limited to indoor and
outdoor design parameters, heat gains and losses, supply and exhaust requirements
for central system and each area of the facility, humidification and dehumidification
requirements, and heat recovery. As a reference, calculations for assessing heating
and cooling loads may include but are not limited to…
Sensible Heat Loads:
External walls, Internal equipment, Computers, Roofs, skylights, Fan (supply,
exhaust and return) heat, Floors, Ceilings and Wall adjacent to unconditioned
spaces, Infiltration, Uninterruptible power supplies, People, Outside ventilation air,
Animals, Lighting, Instrumentation, etc.
Latent Heat Loads:
People, Animals, Outside ventilation air, Moisture generating processes, etc.
C.7.10.b All heating and cooling load calculations shall include a predetermined
safety factor to compensate for load inaccuracies, future flexibility, infiltration, and air
leakage. Safety factors shall be clearly defined in a report usually submitted at the
end of schematic design.
C.7.11.a The design engineer shall make a detailed and complete inventory of all
laboratory equipment scheduled for installation in each design space, and using
estimated utilization factors, determine the project equipment load requirement.
Equipment utilization factors shall be indicated in a report usually submitted at the
end of schematic design.
C.7.11.b
The designer shall carefully evaluate the following rooms used for laboratory
support, which often have higher than normal cooling loads, as well as evaluate the
use of supplemental units to remove excessive sensible loads affecting these areas
while maintaining minimum ventilation requirements:
Common equipment rooms
Cage and rack washing rooms
Autoclave rooms
Glassware washing rooms
Darkrooms
