Title: Zero Energy College in Rio de Janeiro
The Zero Energy School is a building complex for 1200 students in Rio de Janeiro. The project promotes energy conservation through low energy architecture. From the very beginning the aim was to build a resource-efficient school and thereby prove that it is possible to provide comfort in tropical regions despite low energy consumption. Due to the combination of improvements of the microclimate, the natural ventilation, the sun-shading and the thermally neutral building surfaces, no air conditioning will be necessary. Furthermore, the reduced rainwater runoff will be collected for further use in a solar-driven evaporation cooling system and architectural optimization of the natural lightning situation will provide yearly daylight autonomy of up to 86%. The school is a showcase of energy efficient, technically viable and economically feasible modern architecture.
