In this paper, we describe a novel method for morphological façade analysis. The analysis consists of two parts: façade division and localization of windows. The façade division is based on the façade alignment hypothesis. We accumulate directional color gradients and we analyze the generated profile. Our approach introduces several morphological filters to augment the robustness to problems su...

Green façades with an active water regime and the flowing through substrate itself are not common. This system reduces temperatures incorporates evapotranspiration, which could be more effective than by regular green façades. The use of a double-skin façade ventilated air cavity can reduce heat load, but evapotranspiration it even additional benefits. also serve as key element for reducing surf...

This paper presents a method to automatically refine existing 3D building models with laser points acquired from a terrestrial mobile mapping system (MMS). 3D models derived from aerial imagery are in general less accurate than 3D information derived from terrestrial laser scanning. Therefore, point clouds are used to refine these models in order to make them precisely correspond to the scanned...

In this paper we present a method for representing complex façades. For this purpose we developed a hierarchical decomposition for the façade. The steps of the decomposition are represented as nodes in a typed graph where the leaves are the atomic façade elements. Every node includes necessary attributes for its façade structure. The edges in the graph depict adjacent façade elements providing ...

FAÇADE (Fast and Automatic Clustering Approach to Data Engineering) is a spatial clustering tool that can discover clusters of different sizes, shapes, and densities in noisy spatial data. Compared with the existing clustering methods, FAÇADE has several advantages: first, it separates true data and noise more effectively. Second, most steps of FAÇADE are automatic. Third, it requires only O(nl...

Double skin façade (DSF) system is used in high-rise buildings increasingly in the hot summer and cold winter zone in China, due to its advantages in sound proof, aesthetic appearance and energy efficiency. This paper demonstrated a method of obtaining the thermal characteristics of the double skin façade system using computational fluid dynamics (CFD) techniques, and evaluated the energy perfo...

Double skin façade systems are employed increasingly in high profile buildings, designed by famous Architects, using acclaimed engineering consultants, and being touted as an exemplary “green” building strategy. It is a new technology that is more often found in high-end European and Pacific Rim architecture, and far less often in North American building. For the majority of mainstream architec...

Noise insulation in buildings is an important topic building acoustics. Existing literature shows a clear lack of simulation tools for the design, analysis, and assessment sound performance structures, especially when frequency interest becomes higher. To tackle this problem, numerical based Condensed Transfer Function (CTF) method, alongside piecewise calculation scheme, adapted to investigate...

Double skin façades are adaptive envelopes that aim to improve building energy consumption and comfort performance. Their principle relies on the dynamic management of cavity's ventilation flow shading devices, which can integrate with environmental systems. This research demonstrates possibility modifying existing buildings study unconventional envelope solutions. Scenarios A B show insignific...
