Method of field verification of dynamic pressure in points of use for cold and hot water supply

Abstract

ABSTRACT: The commissioning process is an innovation that requires changes in the design process. Besides that, due to the revision and integration of the technical standards NBR 5626 (ABNT, 1998) and NBR 7198 (ABNT, 1993) in the year of 2020, many requirements were updated and new ones were set. The sum of those factors created the need of research due to the difficulty of integrating the commissioning process in the design process of building systems. Amongst the difficulties encountered, the assessment of performance requirements and criteria on the delivery and operation phases must be addressed. In addition, part of the difficulties occurs due to the lack of clear methods of performance assessment. Therefore, this paper proposes a method of verification of performance criteria for water distribution in cold and hot water building systems. The method was developed based on exploratory research of the related themes, as well as a field application of the method and measuring equipment. The results show that the method can verify the performance criteria stablished, however the measuring instruments require improvement to allow the verification of other criteria that can be required by the Project Owner.
