Abstract

A green building is a sustainable building that is designed, constructed, operated and utilized in an ecologically efficient
manner. This entails the achievement of basic requirements as keeping a healthy and comfort environment, minimizing
energy usage, optimizing using resources (e.g. water, gas, electricity, etc.) and reducing all impacts to the environment.
In this research, an integrated approach has been proposed to ensure that green building design is treated as a unity and holistic system rather than being a collection of stand-alone systems. Emphasis is given to the study of the basic
parameters during conceptual design phase that ensures a green building which controls energy expenditure and hence
enables high building efficiency. Proper site selection, passive design strategies for maximum energy saving, optimum material selection, efficient resources usage, health and safety considerations, environmental quality and recycling of waste are some of the basic items to affect directly buildings energy efficiency. Fuzzy logic, as being a means that gives possibility to embrace and optimize multiple parameters in the process of decision making, has been implemented. Consequently, a computer program has been, herein, put forward to simplify design evaluation by architects using fuzzy ranking design items relative to standard green goal.
