The Environmental Impacts of Fabrication Process; Methods, Equipment and Materials

effrey M Molavi, Peter K Ndungu

The concept of sustainability in construction has been widely accepted among all stakeholders of the industry. However, at present, there has been a lack of sufficient, credible and reliable quantitative indictors, metrics and/or data on the actual benefits of sustainable construction. In particular, reduction of environmental effects during construction activities has been one of the main issues facing stakeholders. This study represents a single process emission analysis for the hollow-core floor systems of our case studies using theconstruction environmental decision support tool (CEDST). A comprehensive set of results is obtained from the study. These results are presented in several categories for comparative assessment - energy use, Carbon Dioxide (CO2), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), PM10 and VOC emissions. Other categories include solid waste and liquid emissions.
