Importance of sunny days for the determination of heat consumption

Abstract

This contribution describes research focused on calculation of heat consumption for part of the town during the winter season. It is based on historical data analysis in the view of the nature of the sun activity and day type. Whole research consists of two major steps. First step describes obvious relation between heat consumption and outside temperature. The relation is expressed in linear formula and then improved it by the inclusion of the information about sun activity during a day and day type. The second step, concerned with dissimilarities, is about separation of sunny and common days, weekend days and week days and then description of the heat consumption individually for these varieties of days. This contribution also shows simple method of substituting sun intensity measurement with comparison of temperature differences.
