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
