An integrative process is a collaborative approach that involves all project stakeholders in the design and decision-making process from the beginning to the end of a project. It aims to optimize the performance, environmental, social, and economic outcomes of a project by considering the interrelationships and synergies between various building and site systems. By identifying overlapping relationships, services and redundancies among systems, an integrative process can result in increased performance and reduced costs, as it can create more efficient, effective, and innovative solutions that meet the project goals and requirements. For example, an integrative process can help to reduce the energy demand of a building by integrating passive design strategies, such as building orientation, envelope design, daylighting, natural ventilation, and shading, which can also improve the indoor environmental quality and occupant comfort. An integrative process can also help to reduce the material and water consumption of a project by reusing existing resources, selecting durable and low-impact materials, and implementing water-efficient fixtures and systems, which can also reduce the waste generation and environmental impact of the project
