BIM-Based Energy Mornitoring with XML Parsing Engine

Abstract

Due to the urgent need for a response to energy security, aging commercial buildings are required to conform to increasingly stringent environmental standards, particularly with regard to energy and water consumption. Solutions to reach the energy-related goals seem to exist. However, it is often difficult to gain synergistic benefits from the installations.The energy savings actually achieved are often disappointing. Systematic measurement and verification are rarely available due to the high initial cost of such studies. Therefore, there is a significant chance that misunderstandings and unrealistic expectations will affect decision making related with building sustainability. The ability to synthesize emerging technologies into a robust computational platform for monitoring coupled human-building environments is lacking. This paper discusses developing a prototype of BIM-based Baseline Building Model (B3M) for aging commercial buildings. As-built BIM of a public building was employed as a platform for delivering user-actionable information to building occupants, maintaining healthy environments, and achieving further energy savings. Initial testing was conducted at the Technology Innovation Center with data collected for four months. The results of this study showed that B3M provides a robust computational platform for monitoring coupled human-building environments. B3M would be a useful system when aging commercial buildings need to measure and verify accurate benefits of the installations. Expanded use of BIM would allow for more detailed analysis of building energy performance. BIM-based building energy models can be designed to store energy performance data such as consumption, temperature, CO2 emissions, occupancy, and humidity. In addition, the connection to the BIM allows facility managers to simulate occupancy changes, facility upgrades, or energy management strategies based on potential energy demandsIf a building baseline model is created directly from an upto-date BIM, the energy model can be regenerated as the operating conditions are updated. Facility management processes can be improved significantly through the use of an as-built BIM that can integrate real-time building performance data. AS-BUILT BIMThe Technology Innovation Center (TIC) of the Milwaukee County Research Park (MCRP) was used as a test bed.Data from the sensors were recorded on Onset's HOBO® Ethernet Communications Data Loggers, model U30-ETH, in 5-minute intervals and were transmitted to the Onset's database server via data organization software HOBOware

A Process to Divide Curved Walls in Ifc-Bim Into Segmented Straight Walls for Building Energy Analysis

“…BEA systems have also been developed with building information modelling (BIM) technology. Since BIM technology has been used in architecture, engineering, and contracting (AEC) industry, a 3D-based building model can be used in the BEA process; using a BIMbased BEA system allows the engineer to easily and accurately calculate or simulate the energy consump-tion of a building (Laine, Karola 2007;Woo et al 2011;Dziugaite-Tumeniene et al 2012;Oh et al 2011;Venckus et al 2012;Ali 2004). However, since there is a problem related to the interoperability of data between BIM-based design software and the BEA system, the 3D model, in general, must be checked and remodelled by the BEA engineer (Maile et al 2007).…”

New Use of BIM-Origami-Based Techniques for Energy Optimisation of Buildings

“…Alahmad et al [38] proposed a combination of sensors and elements of the BIM model for the electrical system of the infrastructure. Other researchers such as Woo et al [39] associated energy consumption with parameters such as temperature, humidity or occupation. Another field related with BEM is the one referred to data interoperability.…”

Analysis of the differences in energy simulation results between Building Information Modeling (BIM)-based simulation method and the detailed simulation method

“…GBS does not provide the functionality to transfer detailed data of the HVAC system that would be needed for building energy simulation. Woo et al (2010) developed a middleware called MCRP Pro using XML parsing engine to integrate sensor data with BIM via an Open Database Connectivity (ODBC) protocol. MCPR pro is developed as a building baseline database management system via RDBLink which is provided in 2009 Revit application programming interface (API).…”
