Carbon - Model Options (Building)

Carbon tab on Model Options dialog

LCA

LCA time of study

Enter the number of years over which the optimisation LCA (Simple) optimisation KPI should be calculated. Note that this setting does not affect One Click LCA outputs or any of the embodied carbon outputs on the Cost and Carbon screen.

Glazing Carbon Model

Glazing CO2 embodied carbon emissions

Enter the carbon emissions for glazing in terms of kgCO2 per kg glass. This is used throughout the embodied carbon emissions calculations.

Glazing coating embodied CO2

Enter the carbon emissions for glazing coatings in terms of kgCO2 per m2 of coated glass. This is used throughout the embodied carbon emissions calculations.

Note: This extra coating factor is currently only applied to low emissivity coatings. Assessment is based on assumptions built into DesignBuilder which compare the glazing U-value with that of a typical unit without Lo-e coating.
