Net Zero Retrofit

Improving the performance of existing buildings for a zero-carbon future

Ensuring Retrofit Projects Deliver in the Race to Net Zero

With 80% of the 2050 building stock already standing, retrofitting existing buildings has a huge part to play in achieving net zero targets. Current retrofit rates need to triple to at least 3% of global stock each year to keep these targets in reach. But how can you be sure of deploying the right strategies? Energy modelling and dynamic tools can provide the insights you need. Ensuring projects deliver across all aspects of energy, carbon, comfort and costs.

Key FEATURES

Delivering Accurate Insights at Key Retrofit Stages

Our comprehensive technology suite can support your retrofit projects at every step. Leveraging dynamic simulation and real building data to optimise existing building performance, increase confidence in retrofit strategies and ensure that performance predictions carry through into operation.

Optimise Existing Building Performance

Get the most from your existing buildings by taking an energy efficiency first approach. Ensuring your building is running optimally is key to maximising the impact of any subsequent retrofit interventions.

  • Get a handle on your existing building data 
  • Understand current performance and where to focus attention
  • Identify low and zero cost controls interventions for near instant payback
  • Optimise energy use, carbon, comfort and costs
  • Unlock financial savings to invest in any subsequent retrofit measures

Increase Confidence in Retrofit Decisions

Dynamic simulation modelling can support detailed assessment of retrofit measures. Test different scenarios and upgrades, compare the impacts, and ensure money and effort is invested where it will have greatest impact.

  • Understand the whole building impact of proposed retrofit measures
  • Increase accuracy of performance predictions with detailed HVAC & operational modelling (e.g. TM54)
  • Calibrate existing models with in-use data to further increase accuracy
  • Mitigate any unintended consequences (e.g. poor ventilation, overheating)
  • Navigate projects with complex requirements/limitations (e.g. historic buildings)
  • Determine the whole-life carbon impact of your choices

Post-Retrofit Commissioning & In-Use Evaluation

A robust commissioning and handover process is essential to ensure that all systems function optimally, meet performance standards, and achieve the intended energy efficiency & carbon improvements post-retrofit.

  • Undertake operational building data visualisation and analysis
  • Perform in-use building performance and post occupancy evaluations
  • Advanced commissioning services (e.g. seasonal, LEED, monitoring-based)
  • Create performance digital twins for ongoing analysis and optimisation
  • Compare operational use against simulated baselines and weather data
  • Undertake NABERS assessments and close the performance gap

Ongoing Monitoring & Performance Tracking

Continuous performance monitoring prevents buildings from drifting back into inefficient use. Ensuring that retrofit investments continue to deliver over time and that predicted outcomes have been achieved.

  • Keep your building running optimally
  • Compare predicted savings against actual building performance (M&V)
  • Keep tabs on actioned improvement projects
  • Prevent operational drift over time
  • Track energy consumption, carbon emissions and costs
  • Ensure healthy, comfortable spaces that meet occupant needs
