Develop a flexible method to assess buildings hosting major sports events environmentally through the world

Specific international institutions are responsible for managing and organizing major sports events besides choosing the hosting city for those events which is a difficult task, as there is a need for an appropriate decision using highly credible and justifiable mechanisms. Assessing the hosting city includes the assessment of sports buildings used in those events; however the diverse characteristics of countries aiming to host sports events raises the problem of obtaining fair environmental assessment results for the submitted projects. There are already a number of environmental assessment methods of buildings around the world and some were used to evaluate a group of major sports buildings in their countries. A particular version of Building Research Establishment Environmental Assessment Method (BREEAM) was used to assess the sports buildings hosting the Olympic Games in London 2012. However, it cannot be used outside England without the presence of several defects in the evaluation process, especially when dealing with different regional characteristics. Many countries are still without environmental assessment methods of their own, besides the unfairness in the comparison of results from available assessment methods among countries. Difficulty finding a standardized assessment method appears because of the spatial and temporal variables. The paper aims to show the importance of having a flexible method that could adapt to all the variables affecting environmental assessment of buildings with different characteristics and conditions of the countries hosting sports events as well as the different time periods, to get the utmost justifiable and precision results when choosing the hosting city.
