    This thesis deals with the following aspects of renewable energy technology;
    solar energy modelling within the urban environment, performance of building
    integrated renewables including solar photovoltaics and micro wind technology.
    The development of hydrogen technology and electric zero emission transport
    is also reviewed.
    Incident solar irradiation models have been developed to accurately incorporate
    the effects of shading, in order to enable the detailed simulation and estimation
    of solar energy systems within the urban environment. Both the Integrated
    Slope Radiation Model (ISRM) and the Sky Radiance Distribution Model
    (SRDM) have been developed to use readily available horizontal sub-hourly or
    hourly solar global and diffuse irradiation data. Shading parameters caused by
    the surroundings, such as building and trees, can be incorporated into the
    models. A software package based on these models has been developed to
    allow the design and simulation of solar energy systems.
    Horizontal solar global irradiation data is readily available around the world.
    However, diffuse irradiation data is available to a lesser extent. To resolve this
    problem and enable the above mentioned incident solar irradiation models to be
    used throughout the world a simple regression set was developed between the
    diffuse ratio, k, and clearness index, kt, to enable the estimation of horizontal
    diffuse irradiation from its horizontal global counterpart.
    A review of building integrated renewable technology has been carried out. This
    includes the review of the performance of Edinburgh Napier University
    photovoltaic facade which has been in operation for over three years. Building
    mounted micro turbine technology is also reviewed.
    Performance analysis of three micro wind turbines installed on the rooftop of
    Edinburgh Napier University was undertaken, along with an analysis of the
    available wind regime observed at roof level. A software package was
    developed to aid the monitoring and analysis of both micro wind turbines and
    their observed wind regime.
    Hydrogen technology is reviewed as part of the development of Napier
    Hydrogen Research Facility, enabling the demonstration of hydrogen
    generation, storage and use from renewables.
    Finally, an analysis and comparison of a zero emission electric scooter with a
    conventional petrol car for use as urban transport was carried out. A driving
    cycle analysis was also undertaken to determine the environmental impact of
    both vehicles.
