Abstract: The paper aims to evaluate the thermal performance of a typical Chinese low-energy residential building in ‘Hot Summer and Cold Winter’ zone where two prototypes within a six-storey healthy housing with low-energy standards have been investigated. According to the building simulation study undertaken, prototype 1 has relatively good thermal performance compared to prototype 2. In the study, the low-energy parameters have been taken into consideration for both prototypes as an input, which is defined as an energy efficiency building code in HSCW zone with an insulated construction and a criterion calculating indoor temperatures. The simulation resultshave shown that the existing Construction Issues, 2006’. Healthy housing has been defined with the minimum limit of available floor area in a current residential building unit in 2004 (CNERCHS 2004). The minimum limit values of available floor area have been listed below in Table 1. Table 1 The minimum limit of available floor area in a Chinese apartment unit UNIT SPACE The minimum limit area (m²) LIVING ROOM 16.20 (3.6mx4.5m) DINING SPACE 7.20 (3.0mx2.4m) MAIN BEDROOM 13.86 (3.3mx4.2m) Chinese low-energy building design standard cannot achieve the thermal comfort requirement introduced bythe ASHREA 55-2004 standard. Furthermore in the study, the adjustment mechanism of occupancy for thermal comfort has been incorporated with the simulation studies. Moreover, the regional thermal sensation measurements have proven that it is SUB BEDROOM (DOUBLE BED) KITCHEN (SINGLE LAYOUT) TOILET Building Layout 11.70 (3.0mx3.9m) 5.55 (1.5mx3.7m) 4.50 (1.8mx2.5m) important to consider both thermal comfort and lowenergy building studies together.
