The Chesapeake Building at
the University of Maryland’s College Park
campus was selected for the project as a representative,
medium size (50,000 ft2) four-story
office building with around 200 occupants. The
building houses university administrative offices
and has a conventional occupancy schedule. Around
25% of the buildings in the US are in the range
of 10,000 and 100,000 ft2 and comprise
about 46% of the total floor space in the US.
Therefore, the Chesapeake Building is a highly
demonstrative choice for the project. The building
is operated primarily on electricity peaking at
around 300 kW, with a daily average consumption
of approximately 200 kW.
The building is divided into
two zones, the bottom two floors represent the
first zone and the top two floors represent the
second zone. The zones have equally spaced areas,
similar occupancy distribution, similar heating
and cooling loads, and is air-conditioned with
a 90-ton rooftop DX packaged roof top unit (RTU).
The RTUs are integrated into the VAV system with
electric reheat for space heating. The zone configuration
is suitable for direct performance comparison
of different systems. The building is a good representative
of a low cost building designed with low-level
HVAC controls. The building is approximately ten
years old and is a suitable demonstration facility
for state and federal buildings.
