At the beginning of this article, it was pointed out that there are a number of different practitioners of IDP, each with a different perspective on how to carry it out. A number of people and organizations have identified the steps involved in applying IDP to a design. It may be useful to summarize three different approaches. Links are provided to explore the details of each of these.
The 3 are:
1. The approach by Nils Larsson of International Initiative for Sustainable Built Environment (iiSBE).
2. The Integrative Design Collaborative20 approach by Bill Reed.
3. The process definition developed at national workshop held in Toronto in 2001.
In addition, IEA Task 23 has published quite a detailed guideline and accompanying software22 that are also useful tools. The Task 23 web link is http://www.iea-shc.org/task23/
The IDP Overview details the steps for each of the elements in the illustration. This approach begins by defining the work that needs to be done before the team is assembled and the first major workshop is held. A kickoff workshop is the first allinclusive, collaborative decision-making meeting and major performance targets are set then. Subsequent workshops will depend on the scale and scope of the project, with larger and more complex projects requiring more workshops to deal with the issues.
The next phase is the first of the iterative loops. Developing the concept design requires the interactive consideration of structure, envelope, lighting and mechanical systems. Once these are determined, more consideration is given to materials and how to properly convey these decisions in contract documents. Quality assurance activities throughout the construction phase and into operations are critical to ensure that what is designed actually gets built. The iiSBE link is http://iisbe.org .
