This glass and slate pavilion, houses two classrooms and a student lounge for Johnson County Community College in Overland Park, Kansas. Located in the center of campus, the pavilion is technically three separate buildings connected by two glass vestibules. The lounge sits directly north of the courtyard (the new and permanent home for Dale Eldred’s Sundial Sculpture) with the classrooms flanking the east and west side. The curtain wall glasses and the slate pieces on this building are all recycled materials. The floor-to-ceiling glass panels were reclaimed from an unfinished Moshe Safdie project in Kansas City while all the slate panels were reclaimed from chalkboards from the surrounding region. The frosted glass louvers are designed to sit at a 22 degree angle to block the direct sun during the summer months and allow the sun to penetrate and heat the thermal mass floors during the winter months.
This pavilion is equipped with many sustainable systems and features both inside and out. The entire building’s mechanical system uses today’s most advanced technology. Variable Refrigerant Flow (VRF) and Energy Recovery Ventilation (ERV) equipments are coupled with sensors that providing automatic cooling and heating to all the spaces. The three 20′ wide green walls, located in each of the main spaces, are illuminated by both natural light and LED grow lights. The walls are automatically watered throughout the day using recycled rainwater that have been collected in an underground 1,500 gallon water cistern. LED down lights are installed to reduce heat loads and energy consumption and three custom light fixtures were designed and installed in the two vestibules and student lounge (read more about these fixtures here). Occupancy sensors with manual override switches are installed in most rooms which automatically turn the lights on and off.
On the roof, 44 photovoltaic (PV) panels and green roof blocks are installed to help reduce the building’s energy loads. The green roof blocks will help reduce the Urban Heat Island (UHI) effect, help remove pollutants and help purify the air. A wind turbine is installed to the help reduce the energy consumption. The PV system and wind turbine combined have been designed to offset the building’s energy consumption by 70%.
