There is huge potential to reduce CO₂ in the building envelope if you choose the right façade construction. The need for aluminium during construction can be reduced by planning larger façade modules.
Reducing the number of materials required means fewer CO₂ emissions during manufacturing – and also fewer joints for large units, which also reduces heat loss. As a result, the improved U value and corresponding increase in energy efficiency have a positive impact on the carbon footprint.
Overall, the right structural changes above and beyond altering the module sizes can mean material savings of up to 40% compared to constructions without material optimisation.
Adjusting screw for CO₂ reduction
During the construction of a window unit, many factors impact the carbon emissions in addition to the choice of material. The basic depth of a profile, the face width, the technology, the reinforcement used, and the surface finishing of PVC-U profiles significantly impact the GWP value of the finished unit. This must be taken into accountduring the project planning stage to enable active control of the CO₂ value of a building.
