CARBON ANALYSIS
Loft Floor And Joists Embodied Carbon
The calculations uses OSB, C24 Timber and Hot-Dip Galvanized Steel for its calculations. The calculations split the loft floor and joists into 3 seperate categories and then added the total of each category to get the total embodied carbon.

The OSB floor have an embodied carbon of 52.416 KgCO2/Kg.
The Timber Joists have an embodied carbon of 52.7436 KgCO2/Kg.
The Joist Hangers have an embodied carbon of 46.2231 KgCO2/Kg.
Total embodied carbon is 1125.9825 Kg of C02.
By keeping the joists exposed and not covered, it reduces the need for more OSB needed to cover the joists therefore reducing the EC by 35.014 KgC02/Kg.
The chart below shows the calculations of the OSB floor, joist and extra OSB to cover joists.
Carbon Emissions Calculations
The data calculations only include material sourcing to the end of the factory processes and not the transportation.
Its important to note that the actual joist would be an open web joist however a timber joist was used for the calculations.
