Designing to optimize indoor comfort using design explorer (tools: Grasshopper+Honeybee, Design Explorer) Output parameters Simulation outputs Filtering results Input parameters black box case (no radiation) 90% glazing (maximum radiation) optimum shade for highest achievable comfort through shading Design Explorer is an online tool that can help filter the output from a CSV spreadsheet containing the input and output parameters generated after running several hundred simulations. In this case, the depth, angle and frequency of shades for a single bay from the floor plan were explored to figure the most optimum output based on daylight and adaptive comfort. The base case was established considering a blackbox room with no radiation penetration to determine the highest possible level of comfort without assisted cooling and checking the daylight and comfort levels with 90% glazed external walls to determine the minimum comfort. ideal summer shade ideal winter shade Adaptive comfort = Annual thermally comfortable conditions without the use of systems (active mechanical heating or cooling) as determined by the ASHRAE standard-55. SDA = Spatial Daylight Autonomy indicates the duration of time in the year in percentage when at least 50% of work hours receive a minimum light level of 300 lux. 9
