A Noded Carbon Emission Tool (NCET) to Measure Embodied Carbon (EC) in Compositional Cementitious Materials

Abstract

The ever evolving modern construction industry is now producing the highest levels of
carbon content adversely affecting the construction associated environment. Although, the impact of
carbon induced emission is quite large, but still not enough measurable standards and tools to scale
these emission are available. This study contributes to the body of knowledge by providing a
Grasshopper based definition to calculate the embodied carbon with respect to the cement
composition by percentage weight. This tool consists of three sections the first section incorporates
the acquisitioned carbon emission factors for Cement, GGBS, Fly ash, NPA, Gypsum, Limestone,
and MAC, the second part includes the Waste/Additional Energy incorporation to the compositional
cementitious material, whereas the third section includes the calculation processes via which the
prior two sections are merged. The resulting output delivers embodied carbon in concerned material
in KgCO2/Kg as a unit.
