Vertical meteorological patterns and their impact on the energy demand of tall buildings

In accordance with the developing economy and growing population, an increasing number of tall buildings have been constructed over last 20 years. 2017, there were 144 new worldwide that 200 m or greater in height; 50% these China. Due to vertical gradient impact meteorological parameters, energy performance differs from general buildings. Few studies exist on changes using measured data at different heights. Most dynamic simulation simulate parameters models. This study explores patterns hourly dry-bulb temperature, relative humidity, wind speed 2007 2017 for a 325 tower Beijing. The temperature decreased significantly altitude (~0.9 °C per 100 m), while daily difference altitude. absolute humidity did not change height. increased approximately 2 m/s m. building showed annual heating load height 320 by 85% 8 m; cooling 20%. Such significant differences thermal loads 300-m-tall confirm need consider simulations A measurement points heights improve accuracy. Guidance selecting metrological measurements is provided based influences loads.
