  3. Abstract:
  4. One of the main concerns in source water protection and supply relates to the savings in water consumption in the building sectors. Office buildings are responsible for a considerable amount of water consumption worldwide. Thus, regulations on office buildings' water consumption would substantially reduce water consumption in the city as a whole. In order to achieve this objective, water indicators should be determined using an appropriate method. The present study focuses on the evaluation of water consumption patterns in an office building as well as the determination of the fundamental indicators for water conservation and optimization of water consumption patterns. To design and introduce the indicators using the Delphi research method, the effective parts in water consumptions for each of the building divisions have been first identified according to the consumption control improvement tools, and the index of each section also been designed. Therefore, one of the goals of this research is to identify and compile appropriate indicators of water consumption in an office building. As the first step, an office building is divided into different sections, including showers, bathrooms, kitchens, green space, and cooling/heating systems. Then, the Delphi method is utilized to prepare effective indicators of water consumption for each section. By determining each section's aforementioned factors, 38 confirmed indicators were presented for water consumption in an office building. In the end, 36 indicators which showed good validity and reliability with Cronbach's alpha values higher than 0.79 as well as Content Validity Ratios (CVR) higher than 0.53, and Content Validity Indices (CVI) higher than 0.8 are proposed as final indicators. © 2022 Jordan Journal of Mechanical and Industrial Engineering.
