The research intends to verify - in some well-known European residential districts characterized by high levels of sustainability - the relationship between urban and building design choices and the outdoor comfort level. Generally the level of comfort outdoors is neglected since the design focuses on the buildings and not on the “empty spaces between the buildings”. In this research four well-known European sustainable neighbourhoods have been selected, have been analyzed based on their design characteristics and have been simulated with ENVI-met (a CFD software) in order to verify the level of comfort outdoors - in particular the values of Predicted Mean Vote, relative humidity, air temperature, wind velocity and direction – in winter and summer climate conditions. The results of the research are: 1) verification of the level of comfort outdoors in the selected sustainable European neighbourhoods; 2) understanding the relationship between design choices and level of comfort outdoors; 3) suggestion and development of design modifications to improve the comfort outdoors in one of the selected neighbourhoods; 4) assessment of the proposed design modifications for the improved neighbourhood with further ENVI-met simulations.

Abstract
The research intends to verify - in some well-known European residential districts characterized by high levels of sustainability - the relationship between urban and building design choices and the outdoor comfort level. Generally the level of comfort outdoors is neglected since the design focuses on the buildings and not on the “empty spaces between the buildings”. In this research four well-known European sustainable neighbourhoods have been selected, have been analyzed based on their design characteristics and have been simulated with ENVI-met (a CFD software) in order to verify the level of comfort outdoors - in particular the values of Predicted Mean Vote, relative humidity, air temperature, wind velocity and direction – in winter and summer climate conditions. The results of the research are: 1) verification of the level of comfort outdoors in the selected sustainable European neighbourhoods; 2) understanding the relationship between design choices and level of comfort outdoors; 3) suggestion and development of design modifications to improve the comfort outdoors in one of the selected neighbourhoods; 4) assessment of the proposed design modifications for the improved neighbourhood with further ENVI-met simulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
