Another one of G-Net 3d architectural visualisation services – shadow studies. These types of renders are often required to see shadow patterns created by proposed new developments. Shadow analysis is based on the architectural plans and information supplied by client. In order to accurately generate shadow analysis study we have to build a 3D model of the proposed development and adjacent buildings. We then use geographical information such as Latitude, Longitude, Site Location and Sea Level heights. This information is then imported into our daylight software program which can accurately calculate shadow castings on four selected dates throughout the year. The images are then rendered in colour or greyscale format. Shadow studies are usually calculated for March 21st, June 21st, September 21st and December 21st, at 9am, 12pm and 3pm. It is also possible to animate all day shadow movements for any selected day of the year. The same stages of 3d work will apply for sunlight analysis. Sunlight analysis is required for structural and interior decisions. It is particularly helpful when trying to quantify solar access on key spaces and surfaces like solar panels, walls and windows, courtyards that need access to sun for plants or people.
