Climate Responsiveness and Facade Design of AQUA-Certified School Buildings
Education is an important element to bring about social,economic and technological changes in any country.The physical infrastructure of schools is however seldom part of education improvement strategies in countries like Brazil.Public school buildings in the state of S(a)o Paulo are managed by its Foundation for Education Development(FDE).In 2010 FDE required that all new buildings were certified under AQUA,the French HQE environmental rating scheme adapted to Brazilian contexts.Building certification was devised as an opportunity to decrease environmental impacts,while improving indoor environment quality,among other performance aspects.Our research goals were to investigate if the certification requirements have a tangible positive impact on building quality,induce climate responsive architecture and provide adequate and comfortable environments for education.Nineteen FDE projects currently seeking AQUA certification were studied.First,we analysed the sample regarding climate responsiveness and critical performance aspects for learning environments.Then,we ran thermal and daylight simulations for a representative classroom to assess contribution from the designed shading devices.Our analysis revealed that orientation of school buildings to suit local climates is neglected.Double loaded corridor floor plans are typically adopted even though they prevent cross-ventilation in classrooms.Solar absorptance of external walls is not compliant in half of the cases.Finally,typical shading device design improves thermal conditions of optimally oriented classrooms,but impairs daylight harvesting in over half of the occupied time.The hypothesis was that AQUA certification of public school buildings would have significant effect on design elements which contribute to environmental comfort conditions.This was not confirmed.The certification had limited capacity to induce climate responsive architecture.For this reason,besides certifications the design process needs enhancement.Design decisions impact must learn from assessment loops,simulations and inputs from users and specialists alike.Finally,building assessment data should inform new school building projects,to guarantee that we are actually advancing in the right direction.
