What is building performance sketching?
‘Sketching’ building performance allows us to inform architects and design teams early so designs can be optimised for energy efficiency and reduced carbon.
The building performance sketch is an analogy of the architectural sketch. A virtual model of the design is created and assessed, and the most influential features are ‘sketched’. This allows our team to model thousands of design iterations to recommend a set of designs that meet all project success criteria.
This is particularly important in early design where it’s easiest and most cost-effective to provide direction on how a wide range of variables can influence performance outcomes.
Parametric modelling helps us optimise:
- material use
- embodied carbon
- facade design
- external shading design
- HVAC design from a whole-of-life perspective.
Additional benefits include:
- reduced costs
- enhanced comfort
- decreased energy use.
Our process for building performance sketching
Goal setting
We start with a stakeholder workshop to set building performance targets. These can include code complaince and targets from sustainability rating tools like Green Star, BREEAM, LEED and WELL.
Initial assessment
We create a virtual 3D model of the design to simulate the building in operation, using local climate data. The estimated building performance is evaluated to determine its likelihood to comply with project success targets and identify design challenges. This assessment helps determine key parameters in which the design should vary to create a cloud of design iterations that meet project KPIs.
Refinement and optimisation
With the bounds set, we can develop hundreds of design iterations to arrive at a set of designs which could either meet all sustainability objectives or provide recommendations to progress further. This integrated design approach allows us to discuss future direction with the design team.
Final report
Our report summarises all assessments as well as documenting the process. It can be used to prove an integrated and data-driven design approach that focuses on sustainability and as evidence for innovation credits in sustainability ratings. A presentation to all stakeholders will accompany the final report to ensure all members are on board.
Detailed design updates
The design direction is defined by the initial modelling exercise. We understand, however, that changes may be needed as design progresses. These updates can be quickly captured in the model to assess against efficiency and comfort criteria before proceeding.
