A numerical calculation model of ALBEDO being applicable for real complex urban surfaces was developed, which is derived from 3-dimensional calculation. The model takes into account the building height distribution, as well as the effects of multiple reflections, shading within an urban canopy and arbitrarily changing solar position. In addition to that, being based on this numerical model, a set of application tools was developed in a GUI environment that serves a more comprehensive and intuitive framework for application users. These advenced tools are separated into 2 parts; the Albedo Calculator version 0.11 and the Albedo Viewer Web-application. The former deals with a user's demands for a particular input condition, in short a detailed calculation, whereas the latter responds very quickly if the user wants to use an input condition that is contained in the database.
