Light Intensity Light is a necessary component of a successful green roof, as all plant species require some level of light intensity to perform photosynthesis. The light intensity throughout the UBC campus varies over the course of a year and undergoes daily cyclical changes in sun altitude and sun angle. There are a variety of building heights throughout campus that provide the opportunity for rooftops of a lower height to be shaded out by taller buildings around them. The light intensity on 23 June 2021 at 12pm can be visualized in the Rayshader Map, with close-up inset maps of the top five most suitable buildings. The light intensity on each of the five most suitable rooftops is fairly consistent with little average changes to the rooftop luminosity between 9am, 12pm and 3pm. At each time analyzed the UBC Life Building had the greatest average light intensity of the top five most suitable, followed by the Civil and Mechanical Engineering Building and Laboratory. This variance between light intensity could impact the planting decisions and the green roof structure chosen. Future Directions An analysis of rooftop material may be necessary to assess retrofit capability. This may be done campus wide using multispectral imaging and performing a classification of rooftop cover types. This would require some rooftop field data collection in order to have ground truth data measurements for rooftop materials. In performing this ground truthing additional data on the rooftop accessibility could be gathered, as well further details on the condition of the rooftop could be noted. These additional data could provide key details on the structure and type of green roof to install. Another possible study is a network analysis for the usage and movement of students, faculty and other campus users throughout the campus, in order elucidate maximum potential viewership and usage of the new green spaces. This may further inform the decision of whether or not to implement a lower maintenance extensive green roof or a more involved intensive green roof.
