Abstract

This paper focus on an engineering approach for facilities managers/ users in Saudi Arabia to determine water budget deviation in commercial buildings. The approach has two parts; the first one converts As-Built drawing of water network area into a simple created template. The template gives a clear and a simple view to track target consumptions in cubic meter within the water network. Also, a formula has been created to distribute the target(s) through the same network. The second part utilizes statistical tools to check the deviation and thereby providing facility managers with the latest financial situation about the buildings’ water network. The College of Business building at Alfaisal University has been chosen to be a case study for implementing the research methodology. It has been found that inner ring and outer ring zones of potable system as well as outer ring zone of non-potable system are not within the budget and therefore, the user had a clear picture about his network and advised to make further investigation.
