The research group thanks the Australian Department of Industry, Science, Energy and Resources for funding this project entitled 鈥淓nergy Efficiency Training and Information鈥. The researchers thankfully acknowledge the property owners and facility managers who kindly provided the building documentation and data on the case study buildings. The research team also thanks NABERS for the kind collaboration, facilitating contacts with facility managers of rated buildings.
Project objectives
- Select mid-size buildings, with energy retrofit potential
- Identify low-hanging fruits (building fabric & services)
- Guide on HVAC&R: replacement vs. retrofit
- Case studies helping building owners & facility managers in early-stage decision making
Project Findings
- Staged interventions to increase the efficiency of existing buildings
- As-built documentation on building fabric often lacking or insufficient
- Still significant savings from lighting (LED not everywhere yet)
- Some interventions on the building fabric are relatively cheap and deliver savings, before working on HVAC&R
- Increasing cooling energy needs by 2030, need to future-proof our buildings
- Appliances not covered in this project, but they represent a significant opportunity for savings.
Existing buildings need to be retrofitted to adapt to global climate change, and their energy efficiency must be improved to avoid vulnerability to volatility in the energy market. Almost 80% of 2050 buildings already exist today, and we must prioritise he efficiency of existing buildings.
Methods
- Input data from Facility Managers
- Inspections limited by the COVID-19 pandemic
- Building performance simulations (with TRNSYS): retrofit scenarios in the current & future (2030 RCP4.5) climates
This project tackles the operational energy consumption challenge for existing buildings, using a real-life case study to visualise the impact of each energy optimisation strategy.
12 case studies from 9 building types are selected as case study to explore opportunities to reduce energy consumption. Several of these buildings are already being retrofitted, and their performance has improved recently.
