Cooling Degree Days for Quick Energy Consumption Estimation in the GCC Countries

Abstract

One of the most useful and simplified approaches in assessing building energy estimates is the degree days method. The heating and cooling requirements can be easily compared for different locations as well as system trends. In this paper, the cooling degree day values for the capitals of the Gulf Cooperation Council (GCC) are presented. Degree day values at different base temperatures are also produced for these locations. These values are useful for engineers and policy makers for evaluating energy demands and their cost for these countries. A typical two-story residential building is considered here and its yearly cooling load is evaluated. The total cooling energy is compared based on the energy cost of the respective GCC countries. The results presented in this investigation illustrated that the cooling load, based on the cooling degree days (CDDs) at a 23 °C base temperature, agrees well with the detailed hourly cooling load simulated by eQuest software. Additionally, the highest CDDs value of 2589 was observed in the city of Doha and the lowest value of 2037 was seen in Riyadh city. The lowest cooling cost of USD 492 corresponds to Muscat, while the highest value of USD 1672 belong to Abu Dubai, partially due to a higher tariff of 0.081 USD/kWh.
