nature displays profound preference for certain specific ratios to design her life-forms. these are geometric relationships that are transcendent and originated from sacred geometry. the view that geometry had a ritual origin is a part of a wider view that civilization itself had a ritual origin, and therefore the history of utilization of sacred geometry by man goes back to many centuries ago....

Tall building can vibrate in both the directions of Along wind and Across wind caused by the flow of wind. Modern Tall buildings designed to satisfy lateral drift requirements, still may oscillate excessively during wind storm. These oscillations can cause some threats to the tall building as buildings with more and more height becomes more vulnerable to oscillate at high speed winds. Sometimes...

To meet the dual challenges of climate change and peak oil, high-performance (lowenergy) buildings must be the rule rather than the exception. Typical buildings today frequently do not deliver the energy performance predicted by designers or desired by the owner. One of the primary reasons for this failure to perform is that building control systems are not designed, installed and/or operated a...

In almost all areas of our society there is an increasing need for up to date digital map databases. Traditionally, different manual, labour intensive and hence costly methods have been used for map updating, with the change detection for the updating being by far the most complex and expensive part. In this paper an automatic change detection method is presented and evaluated. The method only ...

Airborne laser altimetry has become a very popular technique for the acquisition of digital elevation models. The high point density that can be achieved with this technique enables applications of laser data for many other purposes. This paper deals with the construction of 3D models of the urban environment. A three-dimensional version of the well-known Hough transform is used for the extract...

Due to the environmental and economical processes of the world the architectural thinking is started to change radically in the last decades. The danger of the global warming and the climate change motivated us to revalue our activity and its impacts. The concept of sustainability came into being and its role became more and more important in the architecture. It isn‟t visible that the sustaina...

During the planning phase of modern, complex, block-structured, large-area located, but still landscape-harmonized health-care buildings, the key is the optimal positioning of the blocks and functions, simultaneously ensuring the most-effective backup-paths for any transportation route failure in the buildings in order to speed up system operation, reduce maintenance costs and especially to imp...

Latest European Union programs related to energy efficiency underline the need for retrofitting existing buildings, which are responsible for 40% of EU final energy consumption. Although new buildings can be constructed with high performance levels, the majority of the building stock, characterized by a low energy performance, still needs renovation. Thanks to its potential to deliver high ener...

nowadays, distinctive methods are used in evaluation of the criteria in order to making decision. among them the analytic hierarchy process (ahp) is one of the most efficient. due to the seismicity of the vast majority part of the country and also the existence of the large number of the unreinforced masonry buildings, the application of the ahp method in order to reach to the best alternative ...
