Atrium natural ventilation relief skylights and green roof.

Passive Cooling for School
By Hormoz Janssens, P.E., Member ASHRAE

U

sing advanced engineering tools, the design team for City College of San Francisco explored several
iterations of the building envelope, floor plan and roof skylight layout to create one of the largest natu-

rally ventilated and passively cooled buildings in the United States. The challenges to the team included using
the natural environment as much as possible instead of mechanical cooling, minimizing mechanical equipment
room space (all equipment had to be in a mechanical room due to corrosion issues with the site), maximizing net
useable floor area, minimizing energy use, and providing a comfortable atmosphere year-round. In addition to
the design challenges, the project had to be delivered by the construction manager at risk with no cost premium.

About the Author Hormoz Janssens, P.E., is a principal at Interface Engineering in San Francisco. He is a member of the Golden Gate chapter.
