Currently under construction and scheduled for completion in September
2006, this 219,604 gsf veterinary medicine complex is a lesson in
how sustainable features became a campus priority. The complex consists
of three buildings: Building 3A, a research facility comprised of
two structures that are connected to the school's large animal
hospital, and the Instruction Facility (known as IF), a multi-use
teaching and administrative center. Building 3A has research and
instructional laboratories and support, offices and conference facilities,
and specialized laboratories for anatomy, orthopedic materials testing,
and pathology, which includes a BSL-3 facility and tissue digesters.
In 2001, when sustainable options for the laboratories of Building
3A were proposed, green building design had yet to be formally embraced.
By the time design began for IF, the university enthusiastically
endorsed a candidacy for LEED™ Silver, making it the first
building on campus to engage in the LEED™ certification process.
Sustainable design strategies were pursued throughout project
design, including the use of whole building computer modeling and
participation in PGE's "Savings by Design" program. Both
3A and IF were designed using LEED™ as a framework, and both
are expected to exceed California's Title 24 Energy Code. The actual
projected energy saving for Building 3A is 29 percent and for IF,
34 percent. Lessons learned include the following:
- The degree of client commitment required from the beginning
of the project for effective implementation of lab sustainability
options.
- The advantages of using the same contractor for all structures
in a multi-building complex.
- The advantages of using a construction manager/general contractor
approach.
- Importance of coordinating systems operations decisions with
clients and having a designated building occupant responsible
for coordinating systems control.
Labs21 Connection:
The presentation will focus on high-performance building strategies
for unique building elements and the teaching and commons spaces:
- Inventive water conservation. The Building 3A tissue
digester doubles as a unique tool for water conservation. Wash-down
water from necropsy areas is piped into the digester as make-up
water. Wastewater from the BSL-3 necropsy laboratory is also piped
through the digester, where it is neutralized without the need
of a separate treatment center.
- Integrated displacement ventilation. The HVAC system
for the IF auditoriums and classrooms introduces cool supply air
low in the space and exhausts warmer air high in the space. The
system relies on free and open floor space allowing higher temperature
cool conditioned supply air to be introduced at low velocity low
in the space and move throughout the occupied level of the space.
Conditioned air is allowed to deteriorate above the occupied zone
prior to being exhausted.
- Natural ventilation in the commons area. In summer,
the IF central commons is a tempered zone between the heat of
the outdoors and the cool of the enclosed spaces. Significant
thermal mass coupled with lower temperatures at night expedite
a "night flush" approach to cooling the facility's central
space. A radiant slab in the central commons uses recycled air
conditioning water and provides efficient additional cooling in
summer and heating in winter.
