Vegetation moderates a microclimate by casting shadows, increasing light reflection, evaporation and perspiration; and correcting wind patterns. The present study aims to investigate the microclimatic role of vegetated surfaces and bodies in improving thermal comfort in outdoor spaces between buildings. The main research question is which of the green system modes, that is, horizontal vegetatio...

This paper aims at façade reconstruction for subsequent enrichment of LOD2 building models. We use point clouds from dense image matching with imagery both from Mobile Mapping systems and oblique airborne cameras. The interpretation of façade structures is based on a geometric reconstruction. For this purpose a pre-segmentation of the point cloud into façade points and non-façade points is nece...

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...

The paper discusses the importance of greenery in cities. It considers presence green elements inside a typical urban perimeter block and deliberates about their impact on solar radiation level facades yard. A series computer simulations have been done using six combinations surface reflectance (façade/yard) for configurations. were performed with DIVA, plug-in Rhino Oslo (59.91273, 10.74609). ...

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...

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...
