External envelopes are the image of every building creating fundamental component of the scenario of cities. Façades and roofs, are, in principle, very simple means of creating shelter. Roofs, however, have miraculously resisted specialisation and retained simplicity in most of the cases; while facades have developed and become more complex. Curtain walls are the façade of choice in high-rise buildings and an indispensable element of architecture for a contemporary city.Developments in the field of industrialization, energy conservation, environmental impact, digitalisation and lack of labour are nowadays changing the world of construction. It might be expected that during the coming decades building technologies and processes will change drastically. For that reason, there is a strong need to assess current design process to optimize and agile the work streamlines.

WEATHER PROTECTIONTwo requirements have been identified to define weathering protection requirements related to facades: air leakage and water resistance. Project brief factors that impact those requirements have been identified along with design variables that are affected.
