Generation and verification of vertical meteorological data for building energy simulation from a 325-meter Beijing meteorological tower

Abstract

As the number of high-rise buildings increases, so does the demand for meteorological data at different heights. The difference in meteorological elements in the vertical direction should be considered in heating, ventilation, and air conditioning design and building performance simulations (BPS). This study uses a meteorological tower in Beijing as a model to provide a reduced-order method for data of typical meteorological years (TMY) and outdoor air design condition for high-rise buildings. The vertically-translated TMY results obtained by this method could achieve load simulation results close to the average load level of the observed station meteorological data. The difference between the cumulative heat load obtained from vertically-translated TMY data and the average cumulative heat load obtained from observed station meteorological data was 0.82–6.08%. By verifying the vertically-translated data, we observed that the vertically-translated outdoor air design condition at different altitudes were consistent with the direct statistical results based on observation data. This reduced-order method is helpful for modifying energy consumption simulations and the energy-saving designs of high-rise buildings.
