water to the data centers. However, the CO2 heat pump system provides heating to the building as well. The global warming equivalent from heating can be calculated using Eq. 4.3. The value of annual energy consumption for heating is 3026297kWh/year from the gathered data and simulation. The addition of TEWI due to heating and cooling gives the total TEWI value for the conventional system (Equation (4.4)). Table 4-1. Parameters of the refrigerants input into TEWI. 1.
