Abstract

In the current context of increasing global energy demands, buildings contribute to nearly 40% of these demands. To alleviate this issue, the concept of passive buildings has been proposed. Several passive strategies are used for designing a passive building: good insulation and openings, optimal orientation and shading, heat recovery ventilation (HRV) in a heating, ventilation, and air conditioning (HVAC) system, and airtight and thermal bridge reduced design. These four strategies can enhance both energy efficiency and indoor thermal comfort performance. In this study, a new residential passive house, which is located at London, is designed. And its total annual energy consumption and indoor thermal comfort performance are simulated in DesignBuilder. The design of the new passive house makes reasonable integration of the four passive strategies mentioned above, aiming to discuss how well these strategies can help to reach the passive standard. As a result, the simulation results meet the standard, with a total annual energy consumption of 115 kWh/m². Meanwhile, the indoor air temperature of the house is maintained at 20-25℃ for almost 98% of the time in a year, as well as the indoor air humidity stays between 30% and 70%. DesignBuilder gives that the energy performance certificate (EPC) of this new passive house achieves Level A, which has much better energy efficiency than other households in England and Wales.
