CHAPTER 7. ANALYSIS OF MARKET BENEFITS As mentioned earlier in this paper, the data center industry is expanding greatly. If the use of data centers keeps increasing at the present rate, data centers are expected to consume 222 billion kWh/year of total electricity by 2030. Out of this, 50% of the electricity is consumed by the cooling equipment. Waste heat can be recovered from the data centers to heat any buildings nearby. Assuming half of the existing data centers are located at places with climatic conditions similar to West Lafayette, Indiana, 95 TWh of energy can be saved annually by 2030. The model discussed in the previous section can be extended to calculate the potential savings in 2030 in other commercial buildings as shown in Table 7-1. The energy consumption data for these commercial buildings (D&R International, Ltd., 2010) is input into the model to determine the potential savings. Significant energy savings per year can be seen which can lead to important cost and environmental benefits. Table 7-1. Potential savings in 2030 if the heat pump system is applied to other commercial buildings.
