Environmental Implications of Construction Site Energy Use and Electricity Generation1

摘要: The construction industry is responsible for environmental impacts that include air emissions, waste generation, and the use of land, water, energy. However, most prior research attention has focused on these only material selection building operation. focus here energy implications process, specifically on-site consumption. Existing estimates emissions are tied to large vehicles, but other equipment consumes in various forms. This creates a broader boundary considering engines vehicles used activities by estimating effects comparing them national-level impacts. Results indicate fuel almost double levels suggested government reports; accordingly, emission 30% larger particulate matter oxides nitrogen volatile organic compounds. Quantitative qualitative analysis regarding how U.S. diesel engine regulations could significantly reduce from sites also provided. If fully implemented, initiate manufacture portable generators make electricity generation comparable grid terms emissions.
