The objective of this study is to verify that it is necessary to take account of the system response time for more accurate analysis of building thermal performance simulation. In a radiant floor heating system, thermal capacitance of the system is so large that it is required to evaluate the effect of the system response time upon the building thermal performance. To do this, various simulation time steps were examined and a proper time step which can model a system change within the response time was proposed. And simulations were performed with various response time of the thermostatic valve used in radiant floor heating system. It is concluded that the response time does not influence the thermal performance profoundly, especially when supply water temperature is relatively low and the thermal mass of the building is small.
