Building Optimisation using Scenario Modeling and Linked Data

Download to read offline

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.

Editor's Notes

  • {PA)s can relate to one objectGranularityObserved in contextContextualised information for end user
  • Need to pull information from across the enterprise, so you can understand energy use in context
