A building has a peak heating load equal to 18.3 kW and a peak cooling load of 23.8 kW. Estimate the seasonal heating and cooling requirements if the heating degree days are 1240°C-days, the cooling degree days are 980°C-days, the winter indoor temperature is 23°C, and the summer indoor temperature is 25°C. The design outdoor temperature for winter is 2°C, and for summer, it is 39°C.
