Multi-performance Method for Urban Densification

This investigation proposes a 7-steps multi-performance method for urban densification and applies it to an existig urban block located in Tallinn, Estonia. This design workflow has two main features lacked by previous methods: (1) flexible, easy-to-use and fast, minimizing the dependence on time-consuming simulations with need of daylight and dynamic thermal modeling/simulation; (2) performance-driven differentiation of the FAR metric (i.e. room area, daylight, SA, and overheating protection levels). It was used to find the optimal densification strategy depending on 7 different design criteria defined as trade-offs between: floor-area ratio, daylight provision, solar access, and outdoor thermal comfort.
