“…In addition, in a study of the correlations among energy consumption, air pollution and other related variables in Pakistan in 1975-2012, Khan et al [13] have proposed that there is a significant positive correlation and one-way causal relationship, in both the short and the long term, between energy consumption and air pollution. Similar conclusions have also been obtained by other researches, such as Pan et al [14], Sharmina et al [15], Song et al [16], Wang et al [17] and Nasreen et al [18]. In addition, from the perspective of structure, Yang et al [19] used the logarithmic mean Divisia index (LMDI) method to confirm that Chinese energy consumption, energy structure and processing technology affects sulfur dioxide levels and thus, have proposed that controlling energy consumption and optimizing energy structure will be the most effective method for sulfur dioxide reduction.…”

“…Energy-saving efficiency of insulation measures is related to local climatic conditions. Pan et al [9] studied the exterior wall/external insulation in Beijing, Shanghai, and Guangzhou. They found that the best exterior wall/external insulation is achieved in Beijing, a case in which heating load plays a major role.…”

“…Energy savings was significant by increasing the external wall insulation thickness in exterior zones facing all orientations under Beijing's climate, since the heating energy use was dominant and can be reduced remarkably with the increase in insulated thickness (Pan, Chan et al, 2012). Under Shanghai's climate, increasing external wall insulation thickness to over 26mm would not reduce the sum of annual heating and cooling energy uses in the south-facing exterior zone, but would help save energy in exterior zones facing the other three orientations (Pan, Chan et al, 2012). For all exterior zones under Guangzhou's climate, it was, however, hardly possible to reduce the sum of annual heating and cooling energy uses by increasing the external wall insulation thickness (Pan, Chan et al, 2012).…”

Under the experimental and simulation study on comparative energy and economic performance of walls used to enclose air-conditioned spaces under Thai climate, it was found that insulation can generally help improve thermal performance of walls, but the function that a space serves dictates where insulation should be placed and how cost effective it is (Chirarattananon, Hien et al, 2012).…”
