Buildings are not independent systems – the indoor climate and physics of the building interact continuously with the outside microclimate. The scale of interaction extends to other neighbouring buildings, especially in urban areas, through the modification of wind flow, solar access, and energy exchange. Most modern buildings are no longer monolithic systems that exist independently from the environment and consume energy to maintain their own metabolism.
Today, buildings are designed with awareness of climatic conditions and often allow zones of smooth transitions between the inner parts of the building and the outdoors. To understand the microclimate conditions in these transition zones, the modelling system must factor in the dynamics of both the indoor and the outdoor system. The holistic and high-resolution approach of envimet allows for the simulation of the micro scale urban metabolism as a complex system and the energy fluxes at the individual façade element of a single building.
In an exemplary study, a 10-day-long simulation of a model area extending over 80 m x 80 m x 60 m with three buildings has been run in order to analyse the different behaviours of the materials and their influence on the inside air temperatures.
