Given the technical complexity of façade designs, it can be difficult to convey all requirements at concept design stage by submittal of elevations and detail drawings alone. Moving the design into intelligent parametric modelling using packages such as Revit, we can simulate an accurate portrayal of the building concept. Construction materials may then be accurately selected, easily modified and rendered to give the Client a feel for the aesthetic of their development in line with their original design sketches. For commercial benefit of our clients, it is recommended that detailed parametric modeling of involved façade elements be undertaken at the latter design stages, when the architect and design team have evolved concepts and agreed the approach to the system design. By adopting this method the best value is obtained from in-depth modeling. http://www.coronafacade.com/revit.html
