The Organization for School Buildings commissioned our office to design. Roofgardens/ green roofs on four school buildings. Our team undertook a detailed mapping and thermal? modelling of the buildings and the immediate urban surroundings, creating and detailed picture of their bioclimatic needs and the scope for improvement. Our proposal for the bioclimatic design of these school rooftops was prepared with two main criteria in mind: the requirement to improvements in the buildings' energy efficiency and our desire to inspire an ecological conscience in the students, by creating interesting and educational greenspaces.
