Founded in 1866, Minnesota’s Car-leton College was the dream of

pioneers who believed that knowledge was the real frontier. And this pio-neering spirit endures. For example, the small, private liberal arts school was the first college in the world to have an industrial-size wind turbine to generate energy. It is one of only 15 to receive an “A” from The College Sustainability Report Card (www.greenreportcard.org), an interactive website that provides in-depth sus-tainability profiles for hundreds of colleges in all 50 states and Canada.

Now, Carleton College has pushed the boundaries even further with two new sustainably designed, energy-efficient residence halls designed to achieve LEED Gold certification.

Designed by LHB Inc. architects, the new Cassat Hall and Memorial Hall buildings feature 91,536 total square feet, including 56 double-occupancy rooms, 26 single-occu-

pancy rooms, 21 suites and nine full kitchens. The buildings’ footprints were offset by a donated piece of land north of the campus.

The Carleton Col lege design team identified more than 36 dis-tinct aspects to the residence halls that are deemed sustainable fea-tures, including low-flush toilets expected to save 30 percent on

water, copper tiles on southern-fac-ing roofs to deflect heat gain, LED lighting, and sturdy, weather-resis-tant foliage planted around cam-pus. There are also meters for water use and steam generation. Photo-voltaic panels help supply electri-cal needs, estimated at more than 10,000 kW annually. During con-struction, 90 percent of all waste was diverted from landfills and incinerators and redirected back to the manufacturing process. (A full list of building materials is avail-able online at www.EDCmag.com.)

COMBINING AESTHETICS WITH ENERGY EFFICIENCYInsulated concrete forms, or ICFs, were chosen to assist in achieving optimal energy efficiency. The team focused extensively on the building envelopes of the new dormitories. “ICFs were selected for their sustain-able advantages, including durability, high thermal mass, and low air infil-tration,” says LHB Architect’s Mau-reen Ness, AIA, LEED AP, CDT.

Due to the energy performance characteristics of ICF technology and the special occupancy nature of the

buildings (residence halls are occu-pied from late August through April), low-energy-use electric fans replaced the requirement for air-conditioning.

Heating needs are met by in-floor radiant heating systems, which uti-lize steam supplied from a regional steam-generation plant, and supple-mented, as needed, with individual room side-panel electric heat.

Noise attenuation, local materi-als, building comfort and safety, and indoor air quality requirements were also met by the performance characteristics of ICFs, which also accommodated the gable rooftops. “Reward Wall Systems’ ICF prod-uct met all of our sustainable design criteria as well as providing the ver-satility required for the unique build-ing footprints,” Ness says.

The project features ICF load-bearing walls in conjunction with hollow-core precast floor slabs. Aes-thetic requirements were fulfilled with the ICFs, which provide the versatility to use any exterior finish application. Permanent attachment of the brick veneer to the concrete wall was required by the structural design. Reward Wall’s stainless steel tieKey was used to aid in the labor efficiency required to maintain and exceed construction schedules.

Reward Wall Systems and dis-tributor Cemstone worked exten-sively with the architect during the design phase to assist in the devel-opment of accurate cost budget-ing. According to the team, the school saved 20 percent per square foot by using ICFs versus standard

poured walls. According to recent data provided to Reward Wall Systems, the college spent a total of $54,000 additional dollars to upgrade a building with ICFs, PV systems and other green enhance-ments; the college is expected to save more than $29,000 in total

energy use per year (excluding the cost savings from not using air conditioning), meaning a total payback of only 18 months.

CONTINUING EDUCATIONThe award-winning Carleton Col-lege dormitory project was com-

pleted on schedule and on time for the students to move in at the start of the school year. Every lobby or common area in the school has an interactive touch-screen monitor showcasing features of the building. Currently, the college is running energy contests for the students to see who uses the least amount of energy per floor and per room. The college is also holding seminars to educate the community and its stu-dents on the green features of the school and how those green features make an impact for the community.

Carleton College is very serious about its obligations to be a good steward—to protect the environ-ment and be respectful of the planet. This ICF project now has become a benchmark for schools to monitor and an example of how to get stu-dents to play an active roll in curb-ing energy use. W&C
