The Basso Innovative Difference
The Peter Basso Associate team, in close coordination with
project architect TMP Associates, met the challenge by designing
an HVAC and electrical system which, when integrated with the
building layout designed by the architect, provides the Dearborn
Community with the definitive facility.
One critical element of the project was dehumidification of the
recreational spaces. An
energy recovery type dehumidification system conditions the air to
the natatorium, and
the air is distributed to the space through a fabric duct system.
Both the ductwork and dehumidification unit are designed
specifically for the corrosive natatorium atmosphere.
The location of this equipment, along with other mechanical
and electrical equipment, was coordinated with the strict
acoustical requirements of the performing arts area.
The dome-shaped ceiling of the 250,000 square foot multipurpose
space provided a unique challenge for the lighting team.
The room required low level lighting for dining and high
level lighting for trade shows.
The “wedge” shaped central concourse is 320 feet long,
10 feet wide at one end and 70 feet wide at the other, with 15
foot ceiling height at one end and 40 foot ceiling height at the
other. The space
serves as a fitness area and contains a rock climbing wall.
Indirect lighting with supplemental park-like lighting at
the high ceiling end was utilized to reduce glare on the patrons
as they work out.
One final challenge for the design team was adhering to strict
noise criteria in the performing arts center, while providing
adequate comfort levels.
Theaters
traditionally have ventilation schemes utilizing downflow mixed
air with ductwork installed near the roof.
For this facility, a displacement ventilation scheme was
used. A concrete
supply air plenum was installed below the seating plate which
supplies conditioned air to the occupied zone through outlets
under the seats. This
allows the noise criteria to be maintained while providing good
comfort control at lower operating costs.
The PBA design included many features to reduce construction
and operational costs:
The
theater under floor air distribution system requires much less
ductwork than a traditional overhead system.
The
use of multiple energy sources eliminates the need to expand the
central plant.
The
dedicated natatorium energy recovery dehumidification unit
provides conditioned air to the pool area while reducing cost.
A
fabric duct system in the natatorium provides the corrosion
resistance needed for the pool environment, and in the gym and
main concourse it provides a cost effective and aesthetically
pleasing installation.
Occupancy
sensors are widely used for both lighting and HVAC control in
smaller rooms to shut down those systems in rooms that are not
being utilized.
During
non-core hours, the building air systems are zoned to heat and
cool only those areas of the building that are occupied, thus
reducing utility costs.
Low
voltage lighting control was utilized for all large areas and
exterior lighting, providing a single point for control.
