 These examples demonstrate that it is generally not possible to make statements regarding thermal comfort in summer which are more precise than those derived from the categories in Table 1. It is difficult to predict even the summer air change rate, because according to the system, it depends more or less on user behaviour. The outside temperatures and wind speeds which are influenced by the microclimate also affect the removal of heat through night-time ventilation. The year-to-year fluctuations in weather are not subject to any influence in any case. These examples demonstrate that it is generally not possible to make statements regarding thermal comfort in summer which are more precise than those derived from the categories in Table 1.
