In order to achieve this objective, we propose to research the following tasks: definition of the concept of rehabilitation of buildings in the Historic Centre of Chisinau;legislative, normative assurance of rehabilitation of historical heritage in the Republic of Moldova;analysis of the situation in Chisinau on the example of historical buildings with limestone finishes and examination by non-destructive methods of facades;solutions for rehabilitation of facades of historical buildings by comparing two types of technologies. In conclusion, emphasis will be placed on the choice of the most efficient method in terms of material, technology and cost.展开更多

基金When I was in Tehran three years ago,I had the opportunity to visit and meet some architects:this was the starting point to investigate Iranian architecture,especially the residential sector.I would like to acknowledge the seven architectural firms which answered my call and sent me photos and diagrams of the case studies chosen:Admun Studio,Faezeh Hadian Design Studio,Alidoost&Partners,Keivani Architects,Ayeneh Office,TDC Office.Thanks also go to Parham Rashidi for his valuable support in contacting the architects.
文摘Over time,the traditional house in central Iran,which Tehran geographically belongs to,has undergone deep physical and morphological changes as a result of technological,social and economic transformations,passing from the characteristics of an introverted house enclosed by walls overlooking an inner courtyard to the multi-storey condominium with an extroverted outlook.Here the façade becomes a key element:it is a threshold between urban and private,outdoor and indoor.The article shows a mosaic of patterns and materials of the new mid-rise residential building façades via photographs and diagrams to emphasize the strict connection between contemporary design and local tradition.
