Using a Bioclimatic Approach to Developing Combined Pre-design Strategies for Energy-efficient Buildings in China

Abstract

climate data are 30 year daily average from 1971 to 2000. This paper determined each pre-design strategies’ time saving percentage for each city stud-ied from the overall understanding of climate charac-teristics for building design, and provided the energy saving percentage of passive design from a traditional energy consumption point of view through the appli-Journal Abstract This paper presents the work on development of appropriate pre-design strategies for energy-efficient buildings in different climates in China. This study is based on field thermal environment surveys of 13 cities representing the five major climatic types, namely severe cold, cold, hot summer and cold winter, hot summer and warm winter, and mild climate. The comfort zones for the residents who live in these different cities are defined as reference for analyzing outdoor climate conditions. The analyzing reference has been developed based on the thermal neutrality regression function. The Building Bio-climatic Chart method (Szokolay’s CPZ) and the measured weather data (30-year average) of the analyzed cities are adopted to identify each city’s outdoor climate condition and the appropriate passive design strategies. These basic climate analyses could give basic information on architectural initial design guidelines, and also offer an initial concept and data as well to develop passive design for climate zones for China in the future.
