Students at Campus International now learn in a new building designed specifically to support the International Baccalaureate curriculum. The 1.75 acre urban site is located on the Cleveland State University campus, posing a design challenge as the team was tasked with creating a flexible, 21st-century school facility on a tight site.
To provide collaboration spaces, outdoor learning areas, and parking, the building stacks up efficiently on four levels surrounding a central, naturally daylit atrium. Gathering the entire population of the school at least once a week is essential to the program, thus the large atrium space and adjacent cafeteria can be used for this purpose.
The building provides technology-equipped shared project areas outside of each classroom, and connectivity visually to all four levels from these shared areas. Small group areas and distributed administration spaces on each classroom floor allow for flexibility of group size to gather and work together. Shared spaces such as music and a multi-purpose room are primarily located on level one, with only the gymnasium on the third level for efficiency of the structural system. To ensure that technology is integrated into the students’ day, classrooms and breakout spaces contain both digital and analog media. Interior windows throughout inspire students and staff to learn from each other, and the brightly colored walls reflect daylight. Boosting collaboration and physical activity through the use of wide corridors and centrally placed stairs, the sustainably designed school supports students, teachers, and their inquiry-based academic curriculum.
Stacking up efficiently on 4 levels, Campus International School minimizes its exterior envelope while maximizing daylighting. The building uses high performance glazing, and an efficient rainscreen skin with exterior insulation to control energy use. The design team incorporated over 5,500 net square feet of project and collaboration space that did not previously exist. Operating costs and energy use were both reduced on the tight urban site as a result of the space maximization. Generous daylighting is used throughout the building to bring light into classrooms, boosting wellness and reducing heating needs during the winter months.
Campus International K-8 School utilizes an energy efficient design, from the design parameters to the equipment selection to the components that make up the systems. Starting with the design parameters, the air conditioning system utilizes a low temperature supply discharge approach to reduce fan energy. A lower supply temperature in cooling allows the building to take advantage of reduced airflow required for cooling applications. All cooling system components utilize low or non-CFC refrigerants.
The building design also incorporates high efficiency condensing boilers into the heating system that waste less of the combustion gas heat without using more boiler energy. All of the large air handling fans and hydronic system pumps are controlled with variable frequency drives which pinpoint the optimal operating conditions for this equipment during all times of use. This precision control leads to reduced energy consumption during reduced load conditions.
The Energy Star Target Finder shows that the building is 0.1% better than the national average.
Predicted EUI excluding on-site renewable energy contribution = 81.67 kBtu/SF/yr
Predicted EUI including on-site renewable energy contribution = N/A, same as above
Predicted % regional energy reduction = 4%
The school is located in a dense urban area, therefore is directly accessible to several public transportation options. It is walkable to roughly 5 city bus routes and accommodates parking for staff and visitors. Its centralized location has achieved a Walk Score rating of 86, and several large bike racks outside the building accommodate those who cycle to school.
Per local zoning code, a total of 74 parking spaces are required. With 800 daily occupants, the school has a reduced total of 67 spaces that are provided. Of those, 4 are designated car/van pool parking spaces.
100% of the site storm water is managed for water quality and for flood control in an underground storage chamber system beneath the main parking lot. 100% of precipitation is managed on site, whereas 0% waste water is reused on site.
Percent (%) annual regulated potable water use = 4.73 gallons per SF/year
Indoor air quality directly affects the health and well-being of a building’s occupants. Within this school, indoor air quality has been improved through the use of low-emitting materials which contain no or low amounts of volatile organic compounds (VOCs). VOC’s are carbon compounds that become a gas at normal room temperature and contribute to air pollution both directly and through atmospheric photochemical reactions, producing secondary air pollutants such as ozone and peroxyacetyl nitrate. All adhesives, sealants, paints, carpets, and composite materials used throughout this building are low-emitting.
