2. The estimated winter outdoor temperature ti, = -29 ° C
3. The duration of the heating period zot, d = 204
4. The average during the heating period the temperature of the outside air tn.ot, = -1.9 ° C
5. The average temperature of the coldest five days t, = -25 ° C
6. The maximum of the average wind speed rhumbs January Vav, m / s = 4.9
7. The estimated relative humidity of indoor air φv% = 55
