Office and administration buildings in Saudi Arabia are subject to significant annual maintenance costs. To maximize the long-term returns on this class of building, initiatives should be directed to encourage the use of life cycle cost analysis to select the appropriate design alternatives. However, several challenges are involved in the use of life cycle cost analysis in this type of decision-making problem, including satisfying multiple conflicting objectives. The use of building information modeling (BIM) in sustainable design assists in overcoming many problems that arise when using the graphic representations of conventional computer-aided design. These problems arise because the conventional representations do not contain sufficient information for building performance analysis and evaluation, and there is a significant requirement for human intervention and interpretation, which is time-consuming and costly. The proposed research is very important and supports the goals of NSTIP which are aligned with sustainability, environmental conservation, and the use knowledge acquisition. The contributions of the proposed research to new knowledge:  Benchmarking of regional and international rating systems, an initial comprehensive set of criteria have been identified. A total of 112 criteria have been identified and grouped within five main.  Representing and sharing information related to building and construction industry using Building information modeling.  Illustrating the application of BIM project’s execution plan on office building Projects.  Measuring six types of emissions including; Acidification potential, Human Health (HH) particulate, Eutrophication potential, Ozone depletion and Smog. As such, the total direct and indirect emissions can be calculated where these emissions are produced from construction activities during the overall life cycle of the project including manufacturing phase, transportation phase, construction phase, operation/maintenance phase, and deconstruction/demolition phase.  Taking into consideration factors identified by worldwide rating systems, a generic framework is developed to produce the initial step towards behavior examination. The framework starts with a main task of selecting key parameters through a fair benchmarking of worldwide rating systems.

The main objective of the proposed research is to use BIM to select an optimum sustainable building design for Saudi Arabia. To achieve the main objective, the following sub-objectives must be carried out:  Develop a unique green building rating system for Saudi Arabia. This will include identifying criteria suited to the nature of Saudi Arabia and developing a customized scoring system, the Saudi Arabia Green Rating System (SAGRS).  Expand BIM features by creating new libraries and attributes that are effective in the process of green building rating. An example of these libraries is a materials library that will include green and conventional materials commonly used in Saudi Arabia.  Integrate the BIM model with different analysis tools to easily evaluate different alternatives.  Develop a cost model that will take into account initial costs such as construction costs, and all life cycle costs, such as a building’s operation costs and energy consumption.  Integrate the BIM model and its expanded features with SAGRS and the life cycle cost model.  Integrate optimization techniques with the BIM model, SAGRS, and the life cycle cost model. The optimization goal is to maximize the building rating (SAGRS credits), while minimizing life cycle costs.
