The Estimation of Base Temperature for Heating and Cooling Degree-Days for South Korea

Abstract

In South Korea, heating degree-days (HDD) and cooling degree-days (CDD) have been widely used as climatic indicators for the assessment of the impact of climate change, but arbitrary or customary base temperatures have been used for calculation of HDD and CDD. The purpose of this study is to determine real base temperatures to accurately calculate HDD and CDD for South Korea, using monthly electric energy consumption and mean temperature data from 2001 to 2010. The results reveal that the regional electricity demand generally depends on air temperature in a V-shaped curve in urban settings but in an L-shaped curve in rural settings, indicating that the sensitivity of the electricity demand to the temperature change is affected by the size of cities. The South Korean regional base temperatures, defined by a piecewise linear regression method, range from 14.78 to 19.48C. These results suggest that the assessment of climate change impacts on the energy sector in South Korea should be carried out on a regional scale.

“…By employing different T b in compiling DegDays_ 0p25_1970_2018, users can also have flexibility in application of degree‐days across broader climatic regions (Indraganti and Boussaa, ). Recently studies such as Krese et al, () and Lee et al, () have highlighted the sensitivity to the choice of T b both in assessment of energy demands, as well as in shaping policy measures for consumption of residential/commercial cooling and heating devices.…”

“…Selecting an optimum base temperature for the heating and cooling plants is crucial in order to optimize the performance of HVAC plants and to control HVAC related costs in buildings. For example, in USA, UK, and Germany, commonly used base temperatures for the purpose of calculating HDDs and CDDs are 18.3 • C, 15.5 • C and 15 • C [6].…”

A number of researchers have established the HDDs and CDDs of different countries, e.g., Orhan et al [7] established HDDs and CDDs for 78 different cities of Turkey using the historical temperature data from the relevant weather stations.…”

Incorporating residual temperature and specific humidity in predicting weather-dependent warm-season electricity consumption

“…This threshold is referred to as the base temperature for cooling energy demand. This is commonly used to calculate cooling degree days (CDD) to estimate the electricity consumption (Ahmed et al 2012, Al-Hadhrami 2013, Beccali et al 2008, Huang et al 1987, Kadioglu and Sen 1999, Krese et al 2011, Lee et al 2014, Mirasgedis et al 2007, Tselepidaki et al 1994, Valor et al 2001, although using direct meteorological data is often recommended in the first instance (Hekkenberg et al 2009).…”

“…Thus, the human comfort temperature may vary spatially, which may be reflected in the spatial variation of base temperature for cooling demand. For example, Lee et al (2014) reports that the base temperature for cooling demand within South Korea increases with mean annual temperature (table 1). Adaptive human comfort may vary seasonally (Kumar et al 2016, Yang et al 2015, Yun et al 2016, leading to seasonally varying base temperatures for cooling demand.…”
