Increase implementation of sustainable design strategies and lower cost by involving all stakeholders as early on in the design process as possible.

Promote sustainable design by viewing building systems interdependently rather than as isolated units and working in a collaborative manner from the onset of a project. All team members should be involved in the design process as early as possible. Possible team members in addition to the architect, engineers, owner and contractor include tenants, city officials and building officials, energy modelers, utilities, lenders, insurers, and cost estimators.

Gather all stakeholders for early planning meeting and goal setting during pre-design. Hold a design charrette at the beginning of schematic design, followed by periodic team meetings to support collaboration. Compare design strategies to project goals. See for a detailed list of steps in the integrated design process.

Higher design fees, but potential to reduce both construction cost and operating cost. Construction cost can be reduced by up to 10% for single building projects and 30% for a series of projects. (United Kingdom’s Office of Government Commerce [UKOCG], Achieving Excellence in Construction Procurement Guide Vol. 5, 2007, )

Efficient, high performing buildings without added construction cost (and possibly reduced cost); reduction in construction schedule.

All team members must be involved as early as possible. Scope of work in early design phases is larger than in traditional design processes; contracts, fees and schedules must allow for an increased volume of services. Contracts must be written specifically for the integrated design process and resulting contractual relationships, and must clearly identify scope of work. Communication and collaboration between team members is essential.
