Developing a Three-Dimensional Geometric Framework for Greening Buildings’ Façade

It is considerably challenging to alter the design of existing large and tall buildings to make them rely on natural energy due to many reasons. Among them is the large amount of parameters and geometric measurements required, such as height, width, plot ratio, aspect ratio, windows dimensions, etc. In this research, a new automatic algorithm is developed to model the existing buildings façade and extract several important parameters for building greening. The main contributions of this research are the automatic analysis of the digital building model and the detailed microclimatic analysis for each feature within the building façade. The developed algorithm starts with an automatic digital three-dimensional modeling of the building façade, followed by an automated extraction of the required parameters to alter the façade design such as orientation, height, and width. Results show that the proposed method offers very high accuracy and time/cost effective way for parametric modeling of the existing buildings’ façade.
