The project challenge was to create a relatively small addition to the
rear of the existing six-story College of Design facility.
The building program includes housing Iowa State University's Freshman
Core Design program and second year Architecture, Landscape
Architecture, and Interior Design studio classrooms that would be able
to facilitate student interaction, and exploration of ideas.
The project is sustainably designed and has achieved a LEED® Platinum
certification. One of the project's main goals is to create a "living
laboratory" that will demonstrate sustainability to the students
learning in the facility.
The design solution presented is of a "Pavilion" design, pulled slightly
away from the main building and organized as a two-story form. Open
studio classroom environments are efficiently organized around a central
core space that function as flexible experimentation space. The center
volume allows natural daylight to penetrate deep into the center of the
building to the lower level. Clerestory and full height corner perimeter
windows captures daylight into each studio classroom.
The building will essentially require no electric lighting during
daytime hours. The use of a vegetated roof on the facility reduces heat
island affect and storm water management needs on the property.
The building was built on existing concrete site walls that became the
foundation walls for the addition. Concrete foundation walls, footings,
and floor slab are insulated with 2-inches of rigid insulation. As the
building is depressed into the site, a soil berm is also providing
additional passive insulation for two sides of the building. Concrete
was chosen as a material because it is a regional material, and it also
provided recycled content. Floor slabs were polished and left exposed as
the interior finishes for increased life cycle value to the owner, lower
maintenance requirements, and no VOC's to impact IAQ.
The building utilized PPG's Solarban® 60 glazing, Low-E insulated
panels. This provided great solar heat gain value and also has high
visibility rate for daylight potential. A ceramic frit and metal
sunscreen were implemented to protect glazing with a west exposure
helping to reduce solar heat gain. The rest of the facade was
constructed of 2-inch insulated metal panels over continuous rigid
insulation with building wrap, fastened to 6-inch metal studs. The stud
cavity was filled with 6-inch cotton bat insulation. The cotton bat
insulation is 100% recycled cotton material and is also a rapidly
renewable material. The building's envelope had a significant
contribution to daylight and view, energy efficiency, as well as
recycled content percentage.
The roof is an acoustic composite deck system. The metal deck is left
exposed, eliminating the need for additional ceiling finish materials.
The deck/structure is flat and has a minimum of 4-inch rigid insulation
with additional built up insulation to provide drainage slope. The
pavilion has an extensive vegetated roof system that is applied over an
80mil PVC membrane. A green roof was chosen as it provides multiple
benefits to the project: reduces storm water runoff, reduces summer
cooling load, and provides a "teaching tool" and research opportunity
for students and faculty.
