Outdoor UTCI in the courtyard (tools: Grasshopper+Honeybee) The diagrams indicate the Universal Thermal Climate Index, or what the thermal condition ‘feels like’ in the courtyard based on the outdoor temperature, wind speed and relative humidity. The different conditions explored in this scenario are without any shade, with contextual shading by the buildings and surroundings and with shade. With all parameters intact, the shade causes the UTCI to drop by over 12° C Average annual UTCI without context or shade: 38.63° Average annual UTCI without shade but with context: 31.31° Average annual UTCI with shade and context: 26.62° Radiation in the courtyard (tools: Grasshopper+Honeybee, Sketchup+Vray, Photoshop) The outdoor radiation in Phoenix exceeds 1300 kWh/m2. The diagrams on the left indicate the direct + diffused (global) radiation that would be incident on the courtyard of the institute without any shade (but with context, i.e. the building itself) and with complete shade as indicated in the diagram above.
