Folded structures are three-dimensional structures - spatial structures and they belong to the structural systems. The term folded structure defines a folded form of construction, including structures derived from elements which form a folded structure by their mutual relationship in space. For very long time this type of construction has been realized in practice only in of reinforced concrete and made on site, which conditioned the use of a very complicated shell. Development of prefabricated building led to improvements of this type of construction so that the folded structures could be derived by assembly of prefabricated elements and their relationship - monolithization on site. Development of the research of folded structures, starting from their earliest days to today, followed the innovations and latest developments in terms of applied materials and methods of connection. The tendency for the cost effective and quicker construction pushed the folded structures made in reinforced concrete, and led to the construction realized in wood, steel and other modern materials that eventually experienced expansion
A proper approach to restoration of historic buildings is crucial for monumental heritage protection. The objective of the paper is to define a methodology for historic buildings restoration in order to increase energy efficiency and re-usability in accordance with modern standards. The main method used in the paper is the observation of historic buildings during their restoration and exploitation, analysis and evaluation of achieved results regarding energy efficiency and energy saving, through the examples of the buildings belonging to Hilandar Monastery, Mount Athos, in Greece. Mount Athos was inscribed on the UNESCO World Heritage List for its cultural and natural values. This case study discusses the abandoned and dilapidated historic buildings of the Haybarn Complex (Stable, Mulekeepers' House, and Haybarn), the achieved results regarding the restoration of these buildings, their energy efficiency and turning into the premises for occasional stays. The research results are recommendations for increasing energy efficiency while performing the restoration of historic buildings, so that these buildings could be re-used in a new way. The most significant contribution of the paper is the practical test of energy refurbishment of these historic buildings conducted using the principles and methods of energy efficiency, in compliance with conservation requirements and authenticity of historic buildings.
During the last years we have been facing a growing need of involving architects into processes of modern city medialization. Transposing contemporary media logic into architecture must be accompanied by qualitative answers within architectural theory and practice. The field of media facade is interdisciplinary - not only does it involve research within architecture and urbanism, but also within some border areas of technology, urban design, art, culture, media and marketing. Media facade design process involves analyses of some specific design aspects
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
