摘要

Nowadays, the most common characteristic of all regulations and buildings is that heat energy requirement of a building is calculated and evaluated for the whole building, not as a sum of those for individual building components. In this paper, first, the recently revised Turkish standard is described in general, and then compared with the ISO 9164, EN 832 and the German regulation. The calculation procedures presented in the standards are evaluated, based on the results of three different types of buildings. The new TS 825 is an application of ISO 9164 in every respect. It uses the same equation, same restriction and same flexibility. EN 832 is basically similar to the ISO 9164 and so is the new TS 825. The most important difference in EN 832 is that solar energy gain is calculated in quite detail including passive solar gains, as well as direct solar gains. This approach gives more accurate results but need huge and detailed database. German regulation is harmonious with ISO 9164, EN 832 and TS 825 only from the point of view of principles and concepts. However, it is a very simplified one, the calculation method defined in the German regulation gave Q_year far from the actual heating energy requirement of buildings for the countries with moderate climate. The main differences between the calculation methods presented in the standards are “the acceptance of climatic data,” “the calculation method of internal heat gains,” “the calculation method of solar heat gains” and “the acceptance of the air change rate values.”
