LEED Gold Langara Library Uses Wind Towers Instead of Traditional Heating and Cooling
The Langara library is specially designed to make use of the stack effect — cool air is brought in through a wind scoop at the bottom of the building, passes through the underground garage, and travels up through the atria and then finally out through a wind tower. A weather monitoring system operates vents to open or close depending on how much air is needed. Indoor sensors also monitor and control air temperature, humidity, CO2 content and movement. Ground source heating and cooling controls the temperature of the space, resulting in the elimination of traditional HVAC systems.
The library, like all new buildings on the campus, is waiting on its LEED Gold certification and makes use of recycled content, local and low-VOC materials. Natural daylighting floods the study areas, and automatically controlled lighting is turned on only when necessary. Additionally, the reflective roof collects rainwater, which is stored below the building and used to irrigate the new landscape. A sequence of bioswales on the western side of the building process stormwater, removing silt and pollution in the process.
Teeple Architects also designed the strategic master plan for the college to realize their environmental vision. The appearance, program and ecological features are all important aspects of the design of the library and any new buildings from here on out.
