Coupling of Active Technologies and Passive Technologies: Low Energy Design Strategies for Northern Public Buildings with Different Space Characteristics in China

Public buildings consume large amounts of energy in China. When the winter comes, the air pollution caused by heating is getting seriously in the north, which is harmful to people's health. It is essential to study the design strategy of low-energy public buildings. Based on the research data and the computer simulation results, this paper proposes the design principles of low-energy public buildings coupled with active and passive technologies. According to building characteristics in site planning and building layout, the passive architecture design techniques, which are making full use of natural conditions, reduce building initial energy consumption. Integration of active renewable energy technology with buildings would enhance operation performance of these technologies, to supplement the energy of buildings. The strategies provide effective suggestions for architects to design low energy public buildings. (paper)
