This presentation describes the development and initial results of an integrated assessment model for the urban scale (< 150 miles). The model uses a full database of energy sources, devices, and their emissions for the four broad sectors of the energy economy: transportation, industrial, residential, and commercial. We study national energy scenarios for Luxembourg using a detailed energy description and transition methodology, based on an urban adaptation of the MARket ALlocation (MARKAL) Model. Emissions are geo-spatially distributed via a land cover interface and fed to an efficient urban scale air quality transport model. A function representing ozone levels based on primary NOX and VOC emissions are used to produce optimal energy scenarios satisfying air quality regulatory limits. This coupled approach called the LEAQ (Luxembourg Energy Air Quality) model is suitable to address sustainable urban infrastructure and policy questions by exploring future (≈ 50 year horizon) air quality snap shots for different emissions and climate scenarios. We show initial validation and results and compare with ground station measurements.
