摘要：architecture is defined as a symbiosis of function, aesthetics, technology and economics. This paper introduces the concept of development of technology in architecture for a sustainable society. The concept is based on a systemic link building-climate-energy. The scientific analysis of this link allows us to define three technical levels of modern architecture. The lowest level is represented by low energy architecture that gives priority to the element of energy. Climate is defined only by physical parameters here. It is characterized by the production of emissions that deplete the Biocapacity of the Earth. Higher level of architecture is represented by green architecture which gives equal priority to both energy and ecology. Climate is defined by physical and chemical parameters here. It is characterized by the tendency of reduction of emissions production and move towards environmentally clean energy, material and water sources. Sustainable architecture represents the target program of development of human settlements in the interaction of society-energy-ecology. It is characterized by the balance of categories nature-man-technology and by minimizing the emissions production to the extent of their coverage by the Earth＇s ecosystems. This paper introduces design strategy for green building. The basic structure of the strategy defines, and internal structure of the strategy emphasizes, principles and concepts of green buildings. In this strategy, the vital role is played by renewable energy sources as a production technology of the capital provided to man by nature.

摘要：The design and execution of large-scale housing projects always have negative environmental impacts in terms of excessive consumption of non-renewable energy resources and environmental pollution. These negative impacts are multiplied in the case of large-scale housing projects where a large number of standardized units are implemented in a repeated manner. This proposed paper will study and evaluate the environmental impacts of large-scale housing projects according to criteria of environmental design. The case study project is Haram City that is a housing project for small low-income families. The project consists of 50,000 housing units and is located in 6th of October City, which has a hot dry desert climate that necessitates special design considerations and applications of environmental design concepts. The project will be analyzed and evaluated in terms of site layout, design of buildings, orientation, materials used, construction techniques, thermal behavior, landscaping, etc.

摘要：Nowadays, the number of products and also of architectural projects, qualified as ＂sustainable＂, is ever more growing. Following this trend, architectural design may exploit the use of （eco） materials and components to promote a project as sustainable even without considering its impact on the environment; This can be defined as architectural greenwash. This paper considers the case of green envelopes with the aim to evaluate if these can be defined as sustainable design practice. green envelopes provide environmental advantages together with the suggestion to a green aesthetics par excellence. In fact, the integration of vegetation in urban fabric plays an important role in improving ecological and environmental conditions of （and in） cities, although systems can have a high environmental burden. This paper aims to answer the question： Is greening the building envelope a sustainable design practice？ To do so, the paper provides a literature review which includes the main research developed regarding environmental burden, benefits and LCA （life cycle assessment） calculations of green envelopes.
