Abstract

This article examines the influence of the emissivity of façade materials on outdoor microclimatic comfort. The developed methodology is based on the collection of input data regarding the site, the geometrical and technological characterization of the building envelope and the definition of the associated emissivity, the development of alternative emissivity-driven scenarios, the scenario simulation to obtain Outdoor Microclimate Maps (OMMs), and their interpretation and discussion. The operative steps of the proposed simplified method are applied to a specific case study in the city of Bologna made of a mix of buildings, including some towers overlooking an inner courtyard. The emissivity of the façade materials is assumed as the main variable. The results show how, by properly addressing the design choices, it is possible to achieve significant improvements in the outdoor microclimate for the space in-between the considered volumes.
