The project challenge was to create a dynamic learning environment for
three college departments sharing the same space for the first time. The
main project goal is to be a collaboration catalyst for Education,
Psychology and the Community Based Learning students, faculty and
This multi-purpose classroom and instruction building is crafted to be
highly sustainable, technology rich, and campus friendly - designed to
serve others (Campus, Community, Environment, Students, and Faculty)
from its very inception. Designed as a flexible learning environment,
this highly transparent and naturally lit building facilitates new
pedagogical techniques for effective instruction and accomplishment of
beneficial life-long learning objectives. The first building to break
the traditional western boundary of campus, this exciting structure sets
a high bar by achieving a LEED Platinum Certification from the USGBC,
reinforcing Central College's specific sustainable strategies.
Specific sustainable strategies incorporated into this project include a
rain water harvest system, instrumental in reducing the facility's water
use by 82%; a semi-intensive vegetative roof and use of drought
resistant native plantings, rain gardens, and pervious pavers are
incorporated into the landscape, as well as the site design. The
facility's photovoltaic panels, use of natural ventilation, and radiant
floors which serve to heat and cool the structure, all help contribute
to the 32% reduction in overall energy cost. A smart building energy
management system, combined with a green building education system,
collects and shares data on building performance which can be viewed
The Roe Center is designed to have very little impact on our
environment, while architecturally encouraging students and faculty to
have a greater impact on our larger community. Over 40% of the materials
used for construction were from regional sources with over 30% of the
materials used being comprised of recycled content. A construction waste
management plan was incorporated, diverting 80% of the construction and
demolition debris from the landfill.
