Task 23


Task 23 experts developed a wide range of products to support the Integrated Design Process (IDP). These outcomes are results of a development process with internationally agreed structural basics. The material here is structured regards content. To find out relations to the Subtasks click here.

The products can be categorized as following:

  • Methods and Tools support actors to handle complex interrelations of daily design tasks.
  • Documentations describe possible solutions for both technical and processual solutions in practice.
  • Publications provide an overview of dissemination activities during the Task .


Solar Low Energy Buildings and the Integrated Design Process - An Introduction
This is an introductory booklet that explains what Task 23 is about. It briefly addresses the integrated design process, how it was put into practice and what we can learn from that.

Blueprint for a Kick-off Workshop
This document is a basis for the organization of a design team workshop at the very beginning of the integrated design process. The main objective of the workshop is to create common understanding at the beginning of the design process with regard to three important notions:

  1. knowledge about the integrated design process;
  2. a clear perception of the design task;
  3. a co-operative and open attitude towards the other members of the design team.



Integrated Design Process - a Guideline for sustainable and solar-optimized building design
This guide elaborately discusses theory and practice of the Integrated Design Process.
For different purposes (on screen reading or printing) there are different versions available:

  • IDPGuide_print.pdf is only for printing a paper version and contains no links or interactive features. - PDF 7.4 MB
  • IDPGuide_internal.pdf contains interactive features but only provides internal links.
    PDF 4.2 MB
  • IDPGuide.pdf (part of the Task 23 CD package) contains all developed interactive features.

Navigator Tool
The Navigator is an interactive knowledge space (accessible through MS Excel) regarding the Integrated Design Process. It guides actors in the definition and the practice of IDP. It contains the (Generic) Integrated Design Process, illustrated in a graph, that serves as the backbone, showing the different phases of the design process, and important issues during different stages of design. The Navigator also recommends methods and tools how to avoid or solve typical problems. The information within the Navigator can be adjusted and supplemented with new experiences . In this way a personal knowledge space is created.

Navigator User Manual
Explains the handling of the Excel-worksheets and introduces the realized (VB and Macro) features. PDF 1.57 MB

Navigator Dynamic Manual
A more impressive way to get familiar with the NAVIGATOR provides the Dynamic Manual. Short video clips explain a lot of basics and possible adaptations.

Description of Case Stories
This technical report provides detailed information about over 20 buildings and the way they were developed (with a focus on the design process). These building projects were part of the background information used by Task 23 members to develop IDP methods and tools.
PDF 226 KB

Criteria for Decisions in the Design Process
This internal working document evaluates the case story descriptions of over thirty building projects. The conclusions drawn are input for the development of the IDP methods and tools that were developed by SHCP Task 23.

Examples of Integrated Design - Five Low Energy Buildings Created Through Integrated Design
This booklet describes five selected high-performance projects (from the technical report 'Description of Case Stories').
PDF 4.08 MB

The Integrated Design Process in Practice - Demonstration Projects Evaluated
This booklet provides examples of design processes in which some of the Task 23 methods and tools have been used to support the design process. Both the process and the experiences of the actors involved are described.
PDF 3.35 MB


MCDM-23 Tool
MCDM-23 is a new design-tool program that automates many tasks involved in using the Multi-Criteria Decision Making method developed by Task 23. The end products are worksheets, bar charts, and associated star diagrams that quantify how various design schemes stack up according to criteria selected by the user.
Important! Only install MCDM-23 with Windows 95 or Windows 98. Do not install with Windows NT or Windows 2000.
Software Tool 6.4 MB

MCDM-23 User Manual
Introduces the handling and features of the MCDM Software.
PDF 1.51 MB

Multi-Criteria Decision-Making - Method for specifying and prioritizing criteria and goals in design
This booklet explains how to use the Multi Criteria Decision Making method that was developed within Task 23. The method assists the design team to select and to prioritise amongst design criteria, and to evaluate alternative design solutions. In design competitions, the method can assist in developing the program and to select the best design amongst several alternatives.

6. ENERGY 10

Energy 10
Energy 10 is a user-friendly energy simulation system that provides predictions of operating energy performance and identifies the most effective design strategies in reaching this performance level. A major advantage is that Energy 10 can be used from the very start of the design process throughout the design development. Energy 10 is developed by National Renewable Energy Laboratory, Lawrence Berkeley Laboratory, Sustainable Buildings Industry Council, Berkeley Solar Group and US Department of Energy (all in the USA). It is being continuously improved and now offers users an economical and highly effective simulation process for early design support. In June 2002 Energy version 1.5 was released. It is available through Sustainable Buildings Industry Council.


Publications in magazines and at conferences
