A study of green buildings as a necessity for sustainable environmental development and overview of its issues and challenges

Green building (also known as green construction or sustainable building) refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature Buildings that live in harmony. Green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’ Sustainable development encompasses numerous development goals and strategies, with green buildings (GBs) being among the implementations of this concept. The development of GBs is a topic of increasing interest due to the massive development of conventional infrastructure that has the major limitation of environmental degradation, a fact also proven by the research of the scientific literature, with publications in the field enhancing in recent times. Even if strategies applying the GBs concept have many advantages, the public acceptance is not so high due to technologies that still need to be optimized, the relatively low return on investment, and the limited dissemination of information about this concept. Therefore, the manuscript provides a comprehensive assessment in a distinctive way of GBs in the context of sustainable development, clarifying notions and principles of application while integrating green materials and circular economy into the general scientific framework provided. Moreover, a score has been proposed which is assigned to the different types of buildings described, based on the assessment of several specific parameters.
