The paper presents the thermal design of the building heating system of a four educational building № 1 Eurasian innovative university.Data are presented for the period from 1 December to 28 February for three seasons: 2013–2014, 2014–2015, 2015–2016 years. On the basis of the actual thermal design graphics and design of heat were built in the period from 1.12. at 28.02 for three seasons (2013-2014,2014-2015, 2015-2016 years). In these graphs clearly visible difference between the two values. According to calculation, the average difference was 13.02 % of the actual heat consumption.
