The new CY Middle School in Casper, Wyoming is designed to accommodate
three grade levels for a total of 750 students. It is organized along a
north-south "main street" that separates two two-story core academic
wings (east side of main street) from one-story common spaces (west side
of main street). The building divides the site into four distinct
quadrants: approach for staff, bus, and service traffic (north end of
main street); approach for parent and visitor traffic (south end of main
street); outside learning area (east); and athletic play fields (west).
Each of the three grade levels is divided into two smaller "cores," the
two-story core academic areas contain six small learning communities of
125 students each (four in the north wing and two in the south wing).
Each core group of students is provided with a science classroom and
science prep area along with an enclosed classroom, an enclosed double
classroom that can be subdivided with an operable partition, a large CTE
studio space, a conference room, an open work area, a teacher workroom,
lockers, and a restroom group.
In the center of the building, main street opens onto the Cafetorium and
onto an outdoor courtyard sheltered from the wind between the two
academic wings. Students leave their core areas to eat lunch and
socialize in these spaces as well as to receive instruction in the
library media center, music, and athletic facilities.
The environmental conditions present in Casper provided an opportunity
to add alternative energy sources to the state's energy portfolio by
harnessing the ever-present wind and abundant sunshine. CY Middle School
features a wind turbine and photovoltaic array that teach children about
alternative energy, and help to offset the power needs of the laptop
computers issued to each student and teacher in the facility.
The RB+B led design team met the project energy goals by reducing the
lighting power density below 0.75 watts/sf through daylighting
strategies and by utilizing high performance glazing, spray foam
insulation, and careful detailing to improve the building envelope. The
building is "Designed to Earn the Energy Star." The building footprint
is very compact to reduce its exposure to wind and reduce snow-drifting
The poor soils on the site necessitated the creation of a crawl space
capable of housing the HVAC equipment. The crawl space allows the
equipment to run more efficiently, have easier access for maintenance,
and achieve a longer lifespan. Displacement ventilation, demand
controlled ventilation, energy recovery, and condensing boilers are
utilized to reduce the energy required for space conditioning.
