Green Building Performance Analysis and Energy-Saving Design Strategies in Dalian, China

Abstract

In the face of global climate change, there is a pressing and significant need to find low-carbon solutions for China’s construction industry. This research focuses on green public buildings in Dalian, a municipality situated in northern China. We investigated energy-saving design applications based on actual measured data. The results show that the common design aspects in the eco-friendly design of green public buildings encompass the conservation of building-derived energy, water use in buildings, and indoor environmental quality technologies. Optimized design strategies were proposed, focusing on three design elements—building orientation, greening, and shading—that are less considered in the case of buildings. It was found that the optimal orientation of the building is 35° southwest, and two vertical greening methods and three shading design methods were proposed. In addition, the incremental costs of green public buildings with different energy-saving technologies were discussed. This study aims to provide operational performance and feasible emission-reduction strategies for the construction industry in China and worldwide to meet the challenges under the dual carbon target.
