Abstract

Natural ventilation is widely used in low-carbon building design. Its potential is influenced largely by the building's surrounding urban environment. Here we combine the Surface Urban Energy and Water Balance Scheme (SUEWS) and the building energy simulation tool, EnergyPlus, to predict the natural ventilation potential in buildings located in Shanghai. The meteorological data required by EnergyPlus (e.g. air temperature, relative humidity, wind speed profile) are modelled by SUEWS. A densely built neighbourhood (building plan area fraction λP = 0.6) is warmer and less windy compared to a rural area. This results in reduced natural ventilation hours (~60%) in summer, but 15% to 17% more in spring/autumn (cf. rural). The method is intended to improve the accuracy of natural ventilation potential prediction using EnergyPlus in cities.
