Sunny day as sharping factor of heat consumption survey

Abstract

This contribution describes one experiment 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. First step is to describe relation between heat consumption and outside temperature. This relation expresses in linear formula and then improves it by the inclusion of the information about sun activity during a day. The main idea is to separate sunny and common days and then describe heat consumption individually for them. This paper also shows simple method substituting sun intensity measurement by the comparison of temperature differences.
