2) The increase of the number of holes can effectively improve the length range of the wind area behind the building effectively improving the wind environment at the pedestrian height and pollutants lost. 3) When the ratio of the gap between the openings and its height ranges between 1-3, the wind environment in the vertical direction is the most stable, and the wind velocity attenuation is the smallest, which is beneficial to the loss of heat. 4) In the horizontal direction, as gap between the holes and the height of the voids increases, the distribution of the hole becomes more discrete, the wind shadow area at the pedestrian level becomes smaller, and the wind speed amplification factor gradually increases. 5) As the hole is arranged at the upper and lower ends, the wind environment at the pedestrian height will be better and better, and the wind speed amplification factor increase apparently, which is conducive to the loss of heat and pollutants. 6) Whether the building is open at the upper end or the lower end, as the hollow volume is gradually distributed downward, the wind environment in the horizontal direction will gradually improve as the distribution of the voids increase. Therefore, it should be fully considered when designing the building.
