Influence of the urban environment on the effectiveness of natural night-ventilation of an office building

- Combined simulation of wind shielding and solar shading effects of nearby buildings.
- Sensitivity to the variation of environmental albedo and Urban Heat Island scenario.
- Reduction of the cooling efficiency of natural night-ventilation with urban density.
- Strong impact of Urban Heat Island on the cooling efficiency of night-ventilation.
- Importance of modeling the urban environment to support passive cooling design.
