Against the backdrop of the continuous evolution of contemporary urban spatial structure, commercial complexes have surpassed the functional limitations of traditional retail spaces and reconstructed into composite public spaces that integrate urban vitality, cultural representation, and social interaction functions. The urgency of the global ecological crisis and the widespread awakening of public environmental awareness jointly drive a profound transformation of the architectural design paradigm - from a resource consumption model that pursues short-term benefits to a sustainable development path that respects ecological laws, demonstrates humanistic care, and strengthens long-term resilience. The concept of sustainable design is not a mechanical superposition of technical elements or a superficial attachment of conceptual symbols, but a systematic thinking that runs through the entire life cycle of a project: this concept regards architecture as a living organism in continuous dialogue with land, climate, and community, aiming to achieve a dynamic balance between environmental responsibility, social value, and economic efficiency. In environmental design education, the teaching transformation of this concept has long faced the dilemma of "theoretical suspension", manifested as the disconnection between course content and the forefront of the industry, and students find it difficult to translate abstract principles into concrete design strategies. This article is based on a dual perspective of practice and teaching, systematically exploring the organic integration mechanism of sustainable concepts in the planning, construction, and operation of commercial complexes. Through theoretical interpretation, strategic analysis, and the construction of teaching transformation paths, a practical teaching dual track framework is formed, which combines operability, humanistic depth, and forward-looking vision. It provides action guidance for the industry and systematic reference for optimizing the curriculum system of environmental design majors in universities, innovating teaching methods, and deeply integrating industry and education, effectively promoting the realization of the "integration of knowledge and action" educational goal.
