Estimation of a Building Shading Factor in an urban environment (original) (raw)

(The main text is in Bulgarian) The successful design of energy efficient buildings is not limited to the design of energy-storing building envelopes. It is important to consider the possibility to choose a building’s shape that can better utilize the available natural energy resources - solar radiation and light. It is too late to leave the analysis of energy resources for the latest stages of the design process. Therefore it is better to apply it in the earliest design stages, when the architect explores the possible building shapes and planning solutions and to give him a possibility to evaluate in a numerical form the potential of building to utilize the solar energy in the specific urban environment. It is better for the architect to have a programming tool for this, than to follow his intuition only. This publication proposes the interaction between the available solar energy, the shape of the future building and the obstructing volumes in the surrounding urban environment to ...
