building optimisation using scenario modeling and linked data
DESCRIPTION
As buildings become more complex, it becomes more difficult to manage and operate them effectively. The holistic management and maintenance of facilities is a multi-domain problem encompassing financial accounting, building maintenance, human resources, asset management and code compliance, affecting different stakeholders in different ways. One technique, called scenario modelling, customises data-driven decision support for building managers during building operation. However, current implementations of scenario modeling have been limited to data from Building Management Systems with little interaction with other relevant data sources due to interoperability issues. Linked data helps to overcome interoperability challenges to enable data from multiple domains to be merged into holistic scenario models for different stakeholders of the building. The approach is demonstrated using an owner-occupied office building.TRANSCRIPT

Key Challenges
Initially developed a Performance Framework Tool IFC based Encountered significant roadblocks with BIM Originally felt BIM was central pillar of performance
assessment Recognise an as-built BIM is one of many pillars

Linked Building Data
Linking building data builds context between systems Relevant information can linked together to build holistic
views of the building Broader context can be used in decision making
Maintains loose coupling between systems Allows domain systems to focus on their expertise Allows systems to develop independently
