Abstract: In urban areas the daylight available to a building directly from the sky may be compromised, and the contribution from reflected daylight can become more significant. The influence of external obstructions and façade configurations has received some attention, but the impact of daylight reflected from the external ground surrounding an urban building has not been widely examined. This study implemented a lighting simulation analysis of the influence of ground reflection configurations on the daylight availability and the light pollution risk in a typical urban courtyard in Beijing, China. Based on the simulated data, some design strategies are suggested to support landscape and lighting design in a similar urban context.
