Data Formatting for Air Conditioning Systems from As-Built BIM Models for Facility Management (BIM-FM): A Case Study of an Educational Building

Abstract

At present, the application of Building Information Modeling (BIM) for facility management still encounters limitations in terms of data completeness, both graphic and non-graphic information, particularly in As-Built BIM models. This information is essential for efficient building management. This research aims to study, analyze, and define the level of information requirements in BIM models for managing air conditioning systems in educational buildings, based on the Level of Information Need (LOIN) standard, in order to develop an As-Built BIM data set suitable for facility management.

This research employs a mixed-methods approach, including a review of international standards such as Level of Development (LOD) and Level of Information Need (LOIN), as well as case studies of three educational buildings. The data collected were analyzed and used to develop an appropriate As-Built BIM data model for the maintenance of air conditioning systems.

The results present a data set necessary for managing air conditioning systems in educational buildings, covering both split-type and central systems, including large-scale chilled water systems (Chiller) and variable refrigerant flow (VRF) systems. The data set consists of geometric information, alphanumeric data, supporting documents, and asset information. This data can be further used for analyzing air conditioning systems and developing knowledge in future research.
