summary Urban design is a complex process which deals with multitude of aspects to shape quality urban space. On one hand, we have quantitative aspects such as land use, building heights or floor space index which are tackled on top-down approach. On the other hand, we need to take into consideration more subjective, qualitative aspects such as building shapes and space between them based on bottom-up principle.In order to connect both principles, a new, performance-based parametric urban design method is proposed. It is based on a concept of parametric maps, which represent spatial distribution of key building parameters (quantitative criteria, top-down) throughout the area and are preliminary loaded into the virtual urban development area. Once parametric maps are loaded, we begin designing a development by placing the buildings (qualitative criteria, bottom-up), which adapt their parameters while changing their locations. Parametric maps thus represent a link between a set of spatial parameters and the actual shape of each building in a way, which connects both, top-down and bottom-up principles of urban design into a single conceptual framework.In order to evaluate this new method, an interactive prototype application has been developed in Maya (3D modeling software) and the following results were obtained: 1.) a significant speedup is possible in the creation of different design alternatives in early stage of urban design process; 2.) use of parametric maps is most suitable for mid- to large-scale projects (+15 buildings), while they can be redundant for small-scale areas; 3.) possibility of inconsistency with site regulations is diminished.
