A STUDY ON THE COMFORT AND ENERGY EFFECTIVENESS OF PASSIVE DESIGN METHOD (PART 1) : CASE STUDIES USING DETACHED HOUSE MODEL

In this study, we assessed the impact of passive design using both HVAC load and Thermal Autonomy. We calculated the impact quantitatively through large-scale computer simulations and multiple regression analysis. The results quantitatively showed that the impact of passive design elements – such as insulation, indoor thermal mass, and various solar shading/acquisition techniques –varies by region, and identified the effedtive passive design measures for each region. It was also found that the impact of passive design techniques differs significantly when evaluated by HVAC load versus Thermal Autonomy, sometimes even leading to opposing results.
