provided mechanical, electrical, and plumbing (MEP) design services for the
proposed $32 million renovation to Olin Library, a 112,000 sq ft library at
Cornell University. Renovated systems include HVAC, plumbing, fire protection,
power distribution, lighting, stand-by power and emergency systems, and
associated instrumentation and controls.
The HVAC system was designed
for precise temperature and humidity control and utilized active chilled beams
supplied with lake-source chilled water and hot water perimeter radiation. The
cascade control sequences would assure tight temperature and humidity control.
Building ventilation is being handled by multiple outdoor and re-circulating air
handling units. This sequence provides for optimum temperature and humidity
control while reducing energy consumption.
The building fire protection
system consists of standpipes in each stair tower and sprinklers throughout each
floor. With low floor to floor heights and large floor to ceiling book stacks,
the exposed piping needed to be integrated among all of the other architectural
fixtures and MEP systems, this was accomplished using laser scanning and
The electrical system in the building would be upgraded from 208V to
480V distribution. A new unitary substation will be provided to support this
upgrade. New, small feeders will be run to new panels on each floor and motor
control centers in the mechanical spaces. An existing emergency generator will
be utilized for life safety systems including a new fire pump, a new fire alarm
system was included as part of the renovations.
With a projected energy
cost savings of 34%, throughout the design cycle, our in-house team of energy
engineers provided numerous building energy simulations using DOE 2 based
software, to help optimize the MEP systems, as well as the building
envelope/shell. The as-designed building utilizes 27% less energy than a
minimally compliant building designed to meet ASHRAE 90.1-2004 standard. Through
these iterative analyses, Erdman Anthony was able to show that the library
building would meet operational needs while simultaneously meeting Cornell's
high standard of energy-efficiency.
