The book represents One of the major goals of modern approach to building design and construction should be an orientation towards the nature without disturbing its balance. This can be achieved by using renewable energy sources, especially solar energy. In order to achieve a better use of solar energy which is inexhaustible and free, and in order to introduce this energy into buildings, to preserve it and maintain a necessary comfort, it is essential to have certain knowledge in the field of solar architecture. In order to achieve excellence, architects should become experts in the fields that relate to design of passive and active solar buildings, bioclimatic buildings, and buildings that are based on application of modern technologies, techniques and materials, which contributes to reduced energy consumption and sustainable building as well.
