| Issues of energy efficiency in building and construction are constantly discussed by the academic community, practical researchers, construction companies and citizens. Green standards such as; LEED and BREAM considered as the most useful methods to achieved energy consumption in building in addition to achieve the thermal comfort inside space. A building shouldn’t have to be new to follow green standards and achieve energy consumption. Today‘s building owners are retrofitting buildings, converting existing buildings into models of sustainability. They are using new financing tools such as performance contracting to minimize financial risk and maximize energy savings. With an emphasis on ―whole building rather than piecemeal approaches, existing buildings can significantly lower energy consumption while producing financial rewards for owners. A building could be achieved ZERO ENERGY USE by following the reduction, absorption, reclamation and generation steps., and also could reduce energy usage by using alternative sources of lighting, shading devices, solar technologies, type of window's glazing and structure power supply. The main purpose of this work is to review modern ideas and approaches in green standards to achieve energy efficiency in the office buildings in different countries and to study the extent of their environmental and material impact. In addition to studying the efficiency of isolating the facades of the administrative buildings in plants and the role of the quality of glass used in reducing the thermal acquisition within the building to achieve efficiency Energy consumption. The methodology includes the literature review and environmental assessment systems and their role in improving the environmental impact of the building on the surrounding natural environment, as well as presenting some analytical examples that have achieved energy efficiency and zero energy use. Then the study reviews the practical part, including the experience of the treatment for the building envelope (walls and openings), which reduced the consumption of energy inside the building (administrative building of the Canadian University in the administrative capital) by 23% in the case of isolating the walls by plants (west and east orientation) and 33% by using LOW-E glass in the openings as well as isolating the walls with plants. Finally, the research ends with some recommendations on how to reduce energy consumption in the administrative buildings in addition to the recommendations that should be considered in the case of isolating the facades of buildings with plants to reduce the thermal gains inside the building, which in turn reduces energy consumption. | ||||
