To support design team during the integrated design process Task
23 experts developed a diversity of instruments. For each stage of
the design process one or more instrument are available.
Following the time axis of the design process the following instruments
can be applied:
Basics (initiative, feasibility study, program
- The stage of basics is the typical stage to initiate an integrated
design process. The introductory booklet
describes the integrated design process in general and gives a first
impression of its benefits for a new design project. The initiator
of the integrated design process within a design team can use it
to inform the other team members (including the client).
- If team members would like to learn more about the integrated
design process they can consult the Integrated
Design Process Guide. This guide can be helpful throughout the
major part of the design process.
- The Case Story Booklet and the
Demo Projects Booklet show examples
of buildings created through integrated design. They can be quite
informative when discussing the initiative with the client. But
also for the other team members they can be illustrative.
- The Navigator can be introduced
and the design process within the Navigator can be shaped according
to the specific project circumstances.
- In the early stage of the design process
helps design teams to list and prioritise design criteria. Particularly
helpful when defining the program of requirements or in case the
program of requirements is inadequate.
- During pre-design the design team shapes and structures the building
globally. Here the Integrated Design
Process Guide can be of help again. The
shows problems ('issues') that may occur in this stage, including
causes and solutions.
- At the start of the pre-design the members of the design team
will be selected. It is recommended to start the series of meetings
of the design team with a Kick-off
Workshop. The goal is to get to know each other, to introduce
and discuss the design assignment and to make sure the team has
a common understanding about this assignment and how to address
- The Case Story Booklet and the
Demo Projects Booklet will be used
as a reference, showing how design issues were addressed in other
- MCDM23 will be used to discuss
and evaluate the first design schemes of the design team. A result
of the evaluation may be that some parts of the programme of requirements
need to be adjusted.
- During pre-design the first energy calculations can be made with
an energy calculation method that is suitable for this early stage
(like Energy 10). Energy 10 needs
only five, very simple input data (geographical location, building
type, floor area, number of stories, installation type) to get the
- During the stage of concept design the shapes and structures of
the building are transformed into systems. Again the
Design Process Guide provides back ground information, whereas
the Navigator shows very practical
issues, that are relevant to the specific project.
- MCDM23 plays a major part in
this stage as the number of trade offs and design schemes to be
discussed and evaluated grows. Even in this stage it may lead to
adjustments in the (dynamic) program of requirements. Quick evaluations
are necessary to keep the design process going.
- Energy calculations are crucial during concept design as exactly
in this stage decisions have to be made about the interaction between
construction and installations. A tool, like
10, that calculates the energetic and comfort consequences quick
and easy, is helpful and stimulates the project's progress.
- During the stage of design development the systems are materialised
and specified. The Navigator still
is available to help avoiding known problems (it goes even beyond
the stage of design development and also addresses process documentation
and further). The other tools are less prominent here.
