L-pod: A Modular Application for Learning

  1. 1. L-pod: A Modular Application for Learning For years, educators, researchers, architects and the public have understood the power of a well designed school to improve educational performance. The research is abundant and the case studies plenty yet in most cases kids in Florida still do no benefit from all we know. The reasons are numerous and include funding shortages, overcrowded schools and narrow minded decision makers. The L-pod (learning pod) is a modular classroom, built with common construction tech- niques but it also incorporates all the good design applications we know can help students and teachers alike. It also is a highly efficient unit that can minimize its impact on the environment and be a learning tool for the students. s Acoustic l Light Natura it y Flexibil Natural Water Ventilat ion y Indoor Ef ficienc lity Air Qua c tability Constru Energy cy Ef ficien 2009 Sunshine State Modular Classroom Design Competition Entry to design competion submited to the Florida Foundation for Architecture by: Lilian M.

  2. 2. Design Applications Flexibility Providing adequate space for different class sizes, grades Water Conservation and teaching techniques is priority number one. Beyond In addition to very low flow fixtures, our design collects the the essentials, our solution provides additional areas where condensate from the dehumidifier & air conditioning system to be learning can occur like an outdoor extended learning space used for irrigation. This combined with a roof collection system and soft seating area within the classroom. In addition, can provide all the water needed for the landscape elements. the plan layout seeks to reinforce an indoor/outdoor experience. Natural Light Studies show that access to natural light can greatly Natural Ventilation improve learning in classroom. Our strategy has been to In order to accommodate natural ventilation, operable inserts provide extensive natural light through overhead glazing. have been included at all windows. Location of the inserts have Mechanical shades can minimize glare and still provide been offset between north and south windows to allow for cross all light necessary for work during normal day conditions. ventilation when humidity levels allow. South facing windows are partially shaded with canopies. Energy Efficiency Indoor Air Quality Designed as a high performance building, maximum energy Good air quality is achieved with a CO2 sensor controlled HVAC efficiency is achieved through high insulation values, a system, low VOC paints and adhesives, and formaldehyde cool roof and a tight building envelope. A High efficient free furniture and cabinets. Additionally, the fresh air supply wall mount HVAC system, occupancy sensors, fluorescent is pre dried through the dehumidifier system. lighting and abundant natural light also contribute to energy savings. The design also allows for integration of solar power into the canopies. Acoustics Constructability In order to learn teachers and students must be able to hear The L-pod is built using common materials and techniques. and be heard.
