| summary |
Linking solar positions with architecture is a traditional idea, but the use of graphical tools to control sunlight in urban surroundings or buildings is relatively recent. A three-dimensional working environment like the computer offers a new dimension to verify the relationships between the sun and the architecture. This paper shows a new way to calculate the incidence of solar energy in architectural environments using computer 3D modelling. The addition of virtual space visualisation to the analytic computation brings a new tool that simplifies the technical study of sunlight. We have developed several programs based upon the three-dimensional construction of the solar vault and the obstructing objects for a defined position. The first one draws the solar vault for a defined range of dates according to latitude, that is the basis of the energetic calculation. The second program computes the obstruction, i.e. the solar regions that are obstructed by any object. Finally, the third one, allow us to define an orientation to compute the energy that arrives to the analysed positioning. The last program returns the result of calculation in several ways: it shows the amount of energy through colours and makes a list of solar hours according to its energy. |
