Thermal Comfort, Energy and Cost Impacts of PMV Control Considering Individual Metabolic Rate Variations in Residential Building

“…Although these national policies may have a positive effect on reducing heating and cooling energy consumption, they are fragmentary policies and regulations that do not consider the thermal comfort experienced by the occupants [3]. Modern people today spend most of their day in indoor spaces such as houses and offices, and the demand for a pleasant indoor environment is growing as the quality of life improves along with social change [4]. PMV is a comfort index of the occupant that is influenced by air temperature, mean radiant temperature, air velocity, air humidity, clothing, and activity level, and the PMV calculation equation is implemented by software for the convenience of the user [5,6].…”

Development of CO2 Concentration Prediction Tool for Improving Office Indoor Air Quality Considering Economic Cost

“…According to the results of the analysis of the comfort level in Office Space B, similar to the previous one-person office space, the comfort range was PMV = −0.32, as shown in Figure 15 [31,32]. According to the results of the analysis of the comfort level in Office Space B, s to the previous one-person office space, the comfort range was PMV = −0.32, as sho Figure 15 [31,32]. According to the results of the analysis of the comfort level in Office Space B, sim to the previous one-person office space, the comfort range was PMV = −0.32, as show Figure 15 [31,32].…”

“…Considering the comfort level regarding the stuffy office space and uncomfortable indoor air environment, which were problems in the previous qualitative evaluation, the indoor temperature and humidity data measured by the Testo 400 on 20 April were utilized to conduct "CBE Thermal Comfort Tool" [30] PMV analysis. As shown in Figure 6, the analysis indicated a value of −0.17, which is within the comfort range of the ASHRAE Standard 55(2020) [31,32]. During measurement from 15:00 to 17:00 on 20 April, EHP, air purifier, and natural ventilation were not used, and the air speed was selected as 0.17 m/s [33,34].…”
