Conclusions

• radmap

• pros

• Prediction of the total irradiation (annual, seasonal, monthly, ...) on every surface by using a validated simulation code (Radiance)

• Use of meteorological data (no timestep limitations)

• Use of standard sky radiance distributions

• Shading and inter-reflections are taken into account

• Possibility to use very detailed models and even dynamic models (more programming is required in this case)

• Semi-automatic process

• Production of images that are easy to be read and understood

• cons

• If the 3D model is not available, it is necessary to spend some time in modelling the scene with the correct level of detail

• It may be complex to define simulation parameters (need for a Radiance expert)

• Palma di Montechiaro

• About half of the building envelope (facades and roofs) is appropriate for the use of solar systems, despite building obstructions.

• The majority of roofs are suitable for solar applications.
