Urban microclimate impact on ventilation and thermal performance of multi-family residential buildings: two case studies in different climates and urban settings

Submitted by on Thu, 03/02/2023 - 14:51

Urban settings change the microclimate around buildings and resulting thermal comfort inside.  This paper presents a method to consider microclimatic conditions, especially the effect of wind variations around the building, which impacts natural ventilation rates and indoor operative temperatures.

Patterns of urban air pollutants: an overlooked factor when operating ventilation systems.

In most cities, vehicles are the main sources of pollutants. The concentration of pollutants is then known to vary with traffic intensity. Ventilation flows should be adjusted accordingly, which would give improved air quality, especially in dwellings.
