The characterisation of the sample quadrants led to specific design recommendations aimed at maximising thermal comfort. Design measures included tree planting, the replacement of sealed hard surfaces with permeable materials, and - where appropriate - roof planting (on the basis of the City of Vienna’s map of Gründachpotential - ‘green roof potential’). The effects of these measures were simulated under the same climatic conditions as the status-quo. In response to the specific conditions prevailing in each sample quadrant, the design variants focused on different aspects, such as street orientation and width, influence of density of development and the influence of adjacent areas, etc. The evaluation of the data generated focused on those climatic factors most relevant for thermal comfort: wind speed, mean radiant temperature, air temperature and humidity and on the thermal comfort value itself using the index PMV (predicted mean vote). The results are presented as maps depicting mean values and diurnal variations.
