Optioneering Study

This approach is our principal methodology to determine the most direct approach and lowest cost to certifying a building to Passivhaus standard.


Using building energy performance data obtained through the energy modelling, we can produce an optioneering engine capable of testing a multitude of architectural, structural, fabric, and technology approaches - both individually or in combination/phased. We will capture any existing proposals or items from brief and undertake an ideation process to generate a body of feasible solutions for the project.


The output from the optioneering analysis will include the following:

  • Detailed operational carbon (including heating and cooling impacts)

  • Detailed whole life carbon (if the optional Embodied Carbon Analysis is commissioned)

  • Outline/proportional costing

  • Other qualitative impacts will be mentioned associated with health, comfort, maintenance and durability


Items of potential benefit that will be considered include:

  • Conservation of energy potential

  • MEP feasibility

  • Renewable energy feasibility
