The challenge was to maintain the room temperature while having directly daylighting through the glazed roof. The design team came up with the idea of four stacked timber louvers to allow adequate space under the roof so that the captured heat can be removed by cross ventilation before radiating into the room. The louver acts as both the shading device and the structural support. Measurements since completion show good performance with daytime lux levels between 800 and 1,300 and temperature below 27ºC when outside temperature on a sunny day was 32ºC
