“…[12]. Solar-reflective "cool" walls can produce different results in summer and winter, reducing heat in summer and increasing it in winter [14,15]. Levinson found that the cost of household heating and ventilation energy can be saved by 31% through the flexible use of shading, reflection, and other methods [16].…”

It has been proposed in China that the country should reach a “carbon peak” by 2030 and be “carbon neutral” by 2060. In the context of energy conservation and emission reduction, the country’s energy structure needs to be transformed to improve the technology level and more widespread consumption of renewable energy. The global renewable energy utilization situation is first analyzed in this study from the perspective of renewable energy and the buildings using it, highlighting the importance of the application of renewable energy in buildings. Secondly, from the perspective of solar energy utilization technology, ground source heat pump technology, and systems for managing energy use in buildings, the progressiveness of renewable energy applications in buildings is analyzed. The application of these technologies in buildings is demonstrated from various angles. Thirdly, the development prospect of buildings using renewable energy is discussed from the perspective of the promotion of renewable energy-powered buildings and green construction. The development prospects of buildings using renewable energy are discussed from the economic benefits of green finance, the promotion and social support of renewable energy, and the environmental benefits of green buildings. Finally, based on studies in the United States, the United Kingdom, Russia, and China, the international energy policy and development direction, as well as the evaluation criteria of green buildings, are discussed, along with an assessment system for green buildings that is complementary to the strategic agreement.

As construction becomes greener, people have higher and higher requirements for engineering project management, which makes it necessary to deeply study the comprehensive optimization of schedule, cost and sustainability level. Adhering to the concept of low carbon and green, the article takes carbon emission factor into the total cost of building construction and improves the traditional cost objective of engineering projects; then quantitatively analyzes the economic, environmental and social impacts of assembled buildings from the perspective of sustainability, and introduces the sustainability objective into the traditional duration-cost problem study, taking the duration of each job in the double code arrow diagram as the independent variable to construct the duration -cost-sustainability level multi-objective optimization model. In order to solve the type effectively, a series of Pareto optimal solutions are obtained using the NSGA-II algorithm, and the efficacy coefficient method is used for program decision making. The results show that the Pareto solution set can provide effective support for the project manager’s decision making, and the NSGA-II algorithm is effective in solving the multi-objective optimization model.
