Country-level meteorological parameters for building energy efficiency in China

Abstract

Accurate basic data are necessary to support performance-based design for achieving carbon peak and carbon neutral targets in the building sector. Meteorological parameters are the prerequisites of building thermal engineering design, heating ventilation and air conditioning design, and energy consumption simulations. Focusing on the key issues such as low spatial coverage and the lack of daily or higher time resolution data, daily and hourly models of the surface meteorological data and solar radiation were established and evaluated. Surface meteorological data and solar radiation data were generated for 1019 cities and towns in China from 1988 to 2017. The data were carefully compared, and the accuracy was proved to be high. All the meteorological parameters can be assessed in the building sector via a sharing platform. Then, country-level meteorological parameters were developed for energy-efficient building assessment in China, based on actual meteorological data in the present study. This set of meteorological parameters may facilitate engineering applications as well as allowing the updating and expansion of relevant building energy efficiency standards. The study was supported by the National Science and Technology Major Project of China during the 13th Five-Year Plan Period, named Fundamental parameters on building energy efficiency in China, comprising of 15 top-ranking universities and institutions in China.
