Green retrofitting of old buildings is an effective approach for the sustainable urban development. It is different from new green building design and lays much emphasis on the locality and adaptability including climate, function and technology. This study uses a case study approach to demonstrate how to conduct green retrofitting of an old university student dormitory building in a southern city of China, Nanning. The target dormitory building was investigated through field measurement and improvement strategies were proposed based on the investigated results. The improvement effects of the proposed strategies were also quantitatively analyzed using numerical simulation. As a result, it was found that wind speeds around the dormitory are increased by about 0.4 m/s; the average noise level is reduced by about 6 dB; the average outdoor air temperature is lowered by about 5 °C; the daylighting hours inside the dormitory are up by above 1 h; the standard-reaching rate of daylighting is improved from 58.34% to 79.64% and the energy saving rate of building air-conditioning load is raised up by about 0.6%. The findings described in this paper can provide design guidance for green retrofitting of university student dormitories in the hot-humid and less-windy climate.
