Framework for Urban Metabolism and Life Cycle Assessment of Hardscape

Research Product Type

White Paper

This white paper advocates that researchers and policy-makers use the analytical approach of combining urban, material flow analysis and elements of life cycle assessment to measure and improve the efficiency of urban hardscape in large urbanized areas.

Fuel and Emissions Calculator (FEC) Version 4.0

Principal Investigator Randall Guensler, Ph.D.
Georgia Institute of Technology

This research will update to the spreadsheet version of the Fuel and Emissions Calculator (FEC) to Version 4.0. The update will incorporate the emission and energy use rates from the latest version of the EPA's MOVES 4.0 regulatory model for conventional and electric vehicles, utilizing the latest matrices from MOVES-Matrix 4.0 (also developed by the research team) and associated source type technology parameters.
