A manufacturing plant of 5500 square meters has 3.8 m high ceilings and changes its inside air three times per hour by maintaining a slightly positive air pressure (100kPa). The room temperature is maintained at 23°C. To assist in the sizing of a heating system it is assume in the design conditions that the outside temperature is -20°C. Basing the heating requirements on the indoor conditions, determine the heating required to compensate for the infiltration. A. 881.5 kw
