This paper describes a new semi-automatic approach developed for modelling historic building façades with Building Information Modelling (BIM) software. Two new developments for BIM software are presented in this paper. The first is a new library of parametric objects which are designed for modelling classical architectural elements from survey data. These library objects are dynamic and have p...

Buildings are large consumers of energy. In the United States of America; they constitute over 33% of the total annual energy consumption, produce 35% of the total carbon dioxide emissions and attribute 40% of landfill wastes. The building industry is also a large consumer of non-renewable materials and this trend has escalated dramatically over the past century. It is essential that we find wa...

Energy efficiency in office buildings has been the center of attention for many researches. This special attention is due to highly energy consumption in this building type. Refinement of facade and building’s envelop is a good approach to reduce buildings energy requirements. Double skin facade concepts are commonly used to achieve that object. Although the concept is not new, there is a growi...

In this research, an analytical method for quantification of the thermal energy performance improvement for a building integrated photovoltaic double-skin façade has provided. The system has been suggested as a retrofit measure for an existing building in Tehran. The effect of thermal performance has been analyzed through computer-assisted developed code using engineering equation solver softwa...

Lately, a double skin façade (DSF) has been increasingly popular as an aesthetic and shading device. A façade with a secondary skin is employed in buildings to let natural light flow into the building without glare and heat. The purpose of this study is to examine the performance of secondary skin in buildings and to investigate the level of natural lighting in buildings that meets visual comfo...

3D city models are of growing interest in various application areas. For instance, they are the basis for city planning, virtual sightseeing tours or simulations. Meanwhile, due to internet services such as Google Earth or Microsoft Bing Maps, 3D representations of buildings are becoming ubiquitous and find their way to the general public. The increasing demand for 3D building models requires e...
