Qualitative Analysis of the Use of Building Performance Simulation for Retrofitting Lower Quality Office Buildings in Australia

Journal Article


Abstract


  • Building Performance Simulation (BPS) has become an important tool in the upgrading of the existing

    commercial building stock. It allows a user to predict energy savings from upgrades, and thereby optimise

    the energy, financial or other benefits of an energy efficiency upgrade. The current paper presents

    the findings from a qualitative investigation into the use of BPS in the Australian commercial building

    retrofitting industry. The interviews had a particular focus on challenges for lower quality (known as

    secondary grade or mid-tier) office buildings. Twelve semi-structured interviews were undertaken with

    stakeholders in the building energy retrofitting industry, including consultants, government administrators

    and building managers. Thematic analysis of the interview data revealed numerous challenges for

    BPS users, primarily related to the lack of reliable, accessible data regarding building operations and energy

    use in Australia. The poor data availability encouraged the use of simulation to inform decisions

    but required the modeller to use assumptions and heuristics to develop the model. This, in turn, necessitated

    a reliance on the expert knowledge of the simulation user, and made the interrogation of a building

    model by a third party problematic.
