Solar is a project that aims to develop a software to receive the necessary data and produce the desired results in terms of sunlight availability inside buildings. The presence of sunlight over time can be predicted using variables such as latitude and longitude, the configuration of windows, balconies and other surfaces of sunlight entry, and a survey of the surrounding obstacles. Its goal is to develop an image processing algorithm that can determine the blocked and unblocked areas for each combination of azimuth and elevation coordinates and generate the desired solar exposure data for new construction or solar exposure analysis of existing buildings. It is hoped that procedures for assessing the thermal quality of buildings will be added at a later stage, with the goal of more efficient energy use.
