Abstract
This study outlines the development of a comparative study of the difference in magnitude of the total incident shortwave solar radiation and the total anthropogenic radiation energy at a built form's given exposed surface area within a representative built form of varying urban environments within the Greater London Authority. The study provides an assessment and quantification of the anthropogenic energy within the GLA, which is rationalized to the highest spatial and temporal resolution possible. The citywide anthropogenic energy is provided at a 1km2 grid. Representative urban environments are assessed and defined based on London's urban characteristics. The anthropogenic energy is then further rationalized to the exposed surface area and compared to of the total incident shortwave solar energy within the representative urban environments. The balance between the two energy sources is compared and the outcome is fit to hourly intensity profiles likely to be seen within the urban environment for different times of the year. The outcome indicates that low-density areas are typically low-rise, predominantly domestic and consume the least amount of energy that medium and high density areas are of varying height, predominantly mixed, and consume a varying amount of energy and, that the very high density areas, with high to high-rise heights, are predominantly non-domestic, and consume a large amount of energy. In addition, the daily exposed surface (wall and roof) energy balance within all representative urban environments is dominated by anthropogenic energy during the winter that during the mid-season the solar and building energy intensity is dependant on density that during the summer, solar energy becomes the dominant energy form within the low to high density areas and, that during an average summer day the roof surface of the very high density area is dominated by the solar energy, but, the anthropogenic energy dominates the canyon surfaces.
