CFC Reviews CMHC Design Report: IDP — Objections to IDP

Author: admin

It is worth discussing some of the standard objections that are raised to the Integrated Design Process. The objections usually are phrased as the following: “We’ve always done IDP” – That may be true, and if so, keep doing it. Usually the people who say this, however, have remarkably few green buildings to show as evidence.
“If you want me to do something different, that implies I’ve been doing it wrong all these years” – Well no, it doesn’t. This is the 21st century, with an entirely new situation for human society, and new problems and demands for the profession to respond to. Think of IDP as a new tool to add to the toolbox to address this new situation.
“The client won’t pay for it” – Possibly not, especially the first time when the value has not been demonstrated to the client, but that’s exactly what is the intent of NRCan’s Commercial Building Incentive Program.
“It affects the schedule and budget” – It may do, but the benefits should more than outweigh the impacts. Experienced teams are finding that the time spent is merely shifted from the latter stages of the design process to the earlier stages. Design costs may or may not be greater. It depends on how well the team manages the project and captures inherent synergies. It is not as if traditional projects always come in on time and under budget. The BC Cancer Agency’s new laboratory in Vancouver, a LEED Gold building, was designed with an IDP process and came in on time, and $10 million under the $100 million budget.
“It means a loss of creative control as an architect” – Not from what I have observed. After all, what generates more creativity—a blank sheet of paper or fitting the program to a tricky site? An integrated design process often generates more creative ideas and solutions. A good analogy is that the architect goes from being a soloist to being the conductor. In any performance the conductor is always visible, and wears a different suit and often his name is in the spotlight. Reviewed by Moishe Alexander.

Everyone, from the owner to the operator, has something critical to contribute to the improved function or performance of the design and everyone must be heard.
Having said that, there are about two dozen actors involved in the design and construction of every building, from gleam-in-the-eye through to operations, and it sometimes is just not practical to have everyone in the room at all times on every issue.
In addition to the usual design team, the core team that needs to be engaged at all times should include, at a minimum, the building owner or owner’s agent, the design facilitator, a cost consultant, an energy simulator and, if the procurement process allows it, a general contractor or contract manager. Representatives of user groups and the facility managers are critical to improved design and should also be invited. Other specialists in particular technologies or relevant issues can be brought in as needed. Energy modelers are also important in showing the energy costs related to particular design scenarios compared to others. Reviewed by Moishe Alexander.

CFC Reviews CMHC Design Report: IDP — What is it?

Author: admin

Integrated Design Process (IDP) was used in the early 1990s, by Canada’s C-20001 program and IDEAS Challenge2 competition to describe a more holistic approach to building design. This design process has been shown to produce more significant results than did investment in capital equipment3. There is now no single “right” definition for IDP. Rather, IDP describes a different, intentional way of approaching sustainable building and community design that offers a much higher likelihood of success than any other approach.
There are an increasing number of practitioners of IDP. Each has a different, and valid, perspective on how to do it, based on their experiences and practices. Most would agree that there are common elements to every definition.
• Goal-driven with the primary goal being sustainability, but with explicit subsidiary goals, objectives and targets set as a means to get there.
• Facilitated by someone whose primary role is not to produce the building design or parts of it, but to be accountable for the process of design.
• Structured to deal with issues and decisions in the right order, to avoid locking in bad performance by making non-reversible decisions with incomplete input or information.
• Clear decision-making for a clearly understood methodology for making decisions and resolving critical conflicts
• Inclusive—everyone, from the owner to the operator, has something critical to contribute to the design and everyone must be heard.
• Collaborative so that the architect is not simply the form-giver, but more the leader of a broader team collaboration with additional active roles earlier in the process.
• Holistic or systemic thinking with the intent of producing something where the whole is greater than the sum of the parts, and which may even be more economic.
• Whole-building budget setting—allows financial trade-offs, so money is spent where it is most beneficial when a holistic solution is found.
• Iterative—to allow for new information to inform or refine previous decisions.
• Non-traditional expertise—on the team, as needed, or brought in at non-traditional times to contribute to the process.
Sustainability is one of the most important issues facing human society today. The challenges as they relate to buildings are complex and the solutions are not simple.
Framing the challenge in terms of motivation and means is one way of clarifying our thinking. Motivation proceeds from a source or ground, towards a goal. The means require some tools and a direction to apply them. Reviewed by Jan Luistermans.
