The designs for green buildings include finding a balance between comfortable home construction and a sustainable environment. Moreover, the application of emerging technology is also used to supplement existing methods in the development of greener buildings to preserve a sustainable built environment. The main problem of this research is how to tackle the environmental parameters balance based on new techniques that are being used for green building optimization. To mitigate the cumulative effect of the constructed climate on human wellbeing and the regular ecosystem, the most popular goals for green buildings should be planned. This can be achieved by efficient use of natural resources such as energy, water, and other resources and minimizing waste. This will contribute to the security of occupant health, enhancement of work performance, emissions control, and improvement of the environment. In the construction of green buildings, several criteria that may contradict, interrelated indistinct and of qualitative and/or quantitative environment are broadened to utilize. This paper provides a detailed state of the art analysis on improving existing practices in green architecture/building using analytical hierarchy process (AHP) techniques to tackle the environmental balancing values based on optimal strategies and designs by green solutions to help make the best possible option from numerous options.

Introduction The buildings that propose a flexible, relaxed, and energy efficient nature for living at a low price has been the aspirations of residents of buildings. Several innovative design tech- nologies have been introduced to accomplish this objective, to improve building efficiency, and to meet a range of human requirements and environmental sustainability [1]. Also, AHP’s inherent capacity to cope with diverse styles of decisions, where it has been normally been applied in its development, has become its executive research aim throughout the last few years [2]. The implementations of green building problems, techniques, and theories are unique for the greatest challenges in structural planning. The techniques are a portion of the design method in urban planning, landscape, and building. Where the role of environmental design is assigned to architects from a single floor to a whole home, from a multi-storied structure to a large urban space that could even be found in a megacity [3]. The architectural design environmental problem is typically formulated as follows: Energies 2022, 15, 4490. https://doi.org/10.3390/en15124490 https://www.mdpi.com/journal/energies
