Effect of MRT variation on the energy consumption in a PMV-controlled office
چکیده انگلیسی

This paper investigates the energy-saving potential of a thermal comfort-controlled office building. A comparative simulation study between the thermal comfort control and conventional thermostatic control is conducted on a building with glass façades where changes in the outdoor temperature and solar radiation over the course of a day affect radiant temperature and thus thermal comfort. To evaluate the thermal performance in the comfort-controlled space, a PMV-based thermal comfort controller, which adjusts the set-point room temperature of the existing thermostatic controller according to the changes of environmental variables, is assumed. The results demonstrate that thermal comfort competes with energy saving in a conventional thermostatic-controlled space. However, it is suggested that thermal comfort control provides consistent thermal comfort as well as energy-saving effect. The results show that energy consumption in a thermal comfort-controlled space is more affected by a change in the mean radiant temperature than in the conventional thermostatic-controlled space. The energy-saving potential in the thermal comfort-controlled space increases with low mean radiant temperature conditions. Although the energy-saving potential is reduced under high mean radiant temperature conditions, it is suggested that thermal comfort control is still a reasonable strategy to achieve both thermal comfort and energy savings simultaneously.
