Award Criteria

  1. Architectural Excellence
    Just as important to the design of a classroom is its appeal. A space that’s used daily should be both pleasing to look at and comfortable to be in—a space that one looks forward to using. What’s pleasing to the eye depends on who’s looking, but often lively colors and materials, and a sensitivity to design are key in making something attractive. The corrugated metal siding, aluminum panels, and simple, clean lines update the exterior with a more contemporary look suitable in both urban and rural contexts, and bright, customized accent colors add life and personality to both the exterior and interior.
  2. Technical Innovation & Sustainability
    We built a classroom with the same quality and life expectancy as its conventionally designed counterpart, with the speed of construction and flexibility of use that can only be found in modular. Unlike traditional modular classrooms, the building uses more cellulose-free materials such as steel and “DensGlass” sheathing that will not support the growth of mold. The classroom features 8 natural daylight sun tunnels, and electrical daylighting sensor controls – all in an integrated package that works together to manage lighting level needs and energy efficiency. Occupancy sensors and programmable thermostats help control and adjust the interior temperature for the hours when the building is actually occupied. The two stage heat pumps HVAC units provide CO2 controls to vary the input of fresh air according to demand based on occupancy. The building has acoustical ceiling tile, recycled floors and perforated acoustical ceiling deck to help control sound intrusion and reverberation.
  3. Cost Effectiveness
    To summarize, an independent report prepared by The Hickory Consortium, Harvard, MA says, “The energy performance of the Green, SmartSpace Modular Classroom, is far better than would be expected for a similar building built to meet the Massachusetts Energy Code or the ASHRAE 91-2004 Standard. Due to better insulation, windows, daylighting, CO2 controlled energy recovery ventilation, and higher efficiency equipment, this building will save approximately 56% of the energy cost in comparison to the stricter ASHRAE 90.1 – 2004 standard.” And “Given the sterling performance of 56% energy savings, this building qualifies for all 10 LEED energy efficiency points.” “In summary, the Green Classroom has all the attributes of a well integrated design, which considers materials, energy, and the environment… and promises to produce remarkable energy, health, and environmental performance.” Other design features such as TPO reflective roofing, sunshades and canopies all help reduce energy use.
