Abstract As high-rise residential complex becomes popular, disadvantageous changes increase in an environmental context. The occupants need more comfortable indoor conditions with higher standard, and cooling and mechanical ventilation as well as heating systems during the design process become critical issue. However, these trends inevitably result in a rapid increase of energy consumption. Thus, the purpose of this study is to develop an optimal indoor environmental control system in high-rise residential complex which maintains comfortable indoor environment as well as reduces energy consumption. For this purpose, combinations of environmental control systems such as ventilation, heating and cooling were set as an integrated environmental control system, then those were evaluated through TRNSYS simulation for 1) PMV to measure comfort levels of the occupants and 2) energy performance to provide the comfortable indoor environmental conditions.
Using HRV for ventilation, we could reduce heating load by 65% and cooling load by 9% in comparison with ordinary mechanical ventilation. Using radiant floor cooling integrated with dehumidification, we could reduce energy consumption by 69% in comparison with conventional packaged air-conditioning system without causing any condensation problems. In heating system simulation, using radiant floor heating integrated with HRV, we could provide heating with lower floor surface temperature due to the reduced heating load and reduce energy consumption by 56.7%.
