Checking Radiation Model Data with the Method of Building Thermal Environment Simulation

Solar radiation data used for the design of building thermal environment in China are seriously deficient; the radiation estimation model is an important way to supplement radiation data. In order to analyze the influence difference in building thermal environment between measured radiation data and radiation model data quantificationally, building indoor temperature, humidity, cooling and heating load are taken as evaluation indexes, and as the same time, meteorological parameters input files with measured data and model data are constructed separately; with the aid of EnergyPlus, building thermal environment simulation was carried out for two types of building—residential building and office building respectively. Simulation results show that the maximum error percentage of building indoor temperature and relative humidity is 6.22% and 11.00%, respectively, on the typical days; the maximum error percentage of annual cooling and heating load is less than 10%. By comparing the simulation results, the influence difference between measured data and model data referring to building indoor temperature, humidity, load and energy consumption can be reflected. It provides reference for designers to use radiation model data in building energy efficiency design.
