In order to create a high performance building, the building structure, its systems and the site are treated as one interdependent system. This approach is known as the Integrated Design Process (IDP) and brings together the key stakeholders and design professionals – groups like building owners, developers, designers, engineers, consultants, and occupants – to work collaboratively and interactively from the early planning stages through to building occupation.

The structure, building site, lighting systems, heating, ventilation, and air-conditioning systems (HVAC), indoor environment and the end use of the building are viewed as a whole building system rather than a number of separate, independent systems.

IDP allows the design team to identify and better understand the design goals of each party, and provides a forum to take advantage of complementary systems and design principles that can satisfy multiple design goals.
