SPACERGY builds upon the need of planners and designers of developing new models to implement energy transition strategies in the urban environment, departing from the exploitation of reciprocity between space and energy systems. The morphology of urban settlements plays a fundamental role in shaping building cooling demand due to its influence on microclimate processes. In order to understand the relations between spatial characteristics and UHI phenomena, detailed microclimate analyses were carried out for the Floriade district in Almere (NL). The masterplan of Floriade is developed with the initial purpose of hosting the International Horticultural Expo in 2022. Moreover, the new city neighbourhood has been designed to accommodate 660 new residential units after the event and become an example for sustainable and liveable urban areas. The microclimate study of the future residential district was performed by using ENVI-met 4.0 to assess the thermal performance during an extreme hot day. ...
