| Abstract |
Highlights: What are the main findings? The wind environment simulation of the Yezhai Middle School building complex revealed that wind speed exhibits a nonlinear increase with changes in building height, and ground roughness significantly impacts wind speed variations. Heat transfer analysis found that using EPS panels and insulation layers in the renovation of Yezhai Middle School’s exterior walls can effectively prevent cold air infiltration, reduce ex-ternal heat gain, and achieve approximately 24% energy savings. What is the implication of the main finding? Building simulation software applied in campus renovation can help designers make timely adjustments during the design phase to achieve optimal energy-saving and low-carbon design solutions. Through wind environment simulation and exterior wall energy-saving renovations of the Wild Village Middle School complex, scientific basis and practical experience have been pro-vided for low-carbon and energy-saving renovations of other campuses and public buildings. In the context of increasingly deteriorating global ecological conditions and rising carbon emissions from buildings, campus architecture, as the primary environment for youth learning and living, plays a crucial role in low-carbon energy-efficient design, and green environments. This paper takes the case of Yezhai Middle School in Qianshan, Anhui Province, to explore wind environment optimization and facade energy-saving strategies for mountainous campus buildings under existing building stock renovation. In the context of smart city development, integrating advanced technologies and sustainable practices into public infrastructure has become a key objective. Through wind environment simulations and facade energy retrofitting, this study reveals nonlinear increases in wind speed with building height and significant effects of ground roughness on wind speed variations. Adopting EPS panels and insulation layers in facade energy retrofitting reduces energy consumption for winter heating and summer cooling. The renovated facade effectively prevents cold air intrusion and reduces external heat gain, achieving approximately 24% energy savings. This research provides a scientific basis and practical experience for low-carbon energy retrofitting of other campus and public buildings, advancing the construction industry towards green and low-carbon development goals within the framework of smart city initiatives. © 2024 by the authors. |
