Indoor low-frequency noise levels due to road traffic has been modelled for facade examples consisting of a lightweight steel facade, concrete and two types windows. Possible audibility heavy vehicles passing by investigated as well the dependence exposure level on driving speed distance road. The results show that pass-by events may be audible at low frequencies cases complying with building s...

Fig. 1 shows that our system can easily model the failure case described by Müller et al. [MZWvG07] (left), where a global tiling cannot be found because different floors have different numbers of windows. Our automatic facade split, on the other hand, will put such floors in distinct clusters, and as a result they can be split into columns separately (middle). Nevertheless, all windows can be ...

We consider a family of smooth maps on an infinite cylinder which have invariant curves that are nowhere smooth. Most points on such a curve are buried deep within its spiked structure, and the outermost exposed points of the curve constitute an invariant subset which we call the "facade" of the curve. We find that for surprisingly many of the maps in the family, all points in the facades of th...

A fully bottom-up algorithm for extracting blobs in building facades is proposed. Prototype discovery, hypothesis testing and verification are used to identify missing blobs or split the agglomerated ones, when repeated patterns are present in the facade. A novel similarity measure is used for assessing the similarity of subpatterns. The proposed algorithm can detect 80% of the 3589 hand segmen...

ABSTRACT Most office buildings in Germany have either no mechanical ventilation system or a centralized ventilation system with fresh and exhaust air supply. Within the last 10 years some projects using decentralized ventilation systems (DVS) came up. Common for this type of decentralised systems is that they take fresh air directly from outside through the facade via the DVS into the room. Wit...

This paper outlines DROOL, a novel knowledge representation scheme for supporting early stages of the design of multi-technology systems. The key idea behind DROOL is that mechatronic systems should be considered as interlocking flows of matter, energy and information. This provides a powerful framework for thinking about important aspects of conceptual design, and an equally powerful structure...

With the increasing awareness of energy efficiency, many old buildings have to undergo a massive facade energy retrofit. How to predict the visual impact which solar installations on the aesthetic cultural value of these buildings has been a heated debate in Switzerland (and throughout the world). The usual evaluation method to describe the visual impact of BIPV is based on semantic and qualita...

Lightweight steel-framed (LSF) construction, given its advantages, has the potential to reach high standards in energy and environmental performance of buildings, such as nearly zero-energy buildings (nZEB). When compared with traditional construction, LSF system offers distinct benefits in such fields as sustainability, cost-effectiveness, constructive process, and safety at work. Despite the ...
