b) A school building has a design heat loss coefficient of 0.025MW/K and an effective thermal capacity of 2500 MJ/K. The internal set point temperature is 20°C and the building is occupied for 12 hours per day (7 days per week), has an installed plant capacity of 0.5 MW and there is estimated 0.1 MW of gains to the space. For a mean monthly outdoor temperature of 5°C (when the preheat time is 5.1 hours) and system efficiency of 75%, calculate the energy consumption and carbon dioxide emissions for that month. (Assume 0.21kgCO2 per kWh of gas).
