OverviewThis website introduces the work and results of Task 23, a
project within the Solar Heating and Cooling (SHC) programme of the
International Energy Agency. Task 23 "Optimisation of Solar Energy
Use in Large Buildings" has focused its work on exploring the nature
of the Integrated Design Process (IDP), an approach and design
procedure that has proven to be highly effective in producing
high-performance and environmentally-friendly buildings.
The objectives of the Task were reached
step by step by dividing the work into four
Participants from twelve countries were
involved in this Task over a five-year period, putting together the
expertise from researchers, architects and consultants in producing
a practical approach towards IDP. The IDP approach has been applied
in a number of real design processes, and the evaluation of this
experience has provided valuable feedback.
To significantly reduce the total energy use in large buildings, it
is necessary to use several technologies, such as energy
conservation, daylighting, passive solar, active solar, and
photovoltaics, in combination. The designers of these buildings
therefore need to find the optimum combinations of technologies for
each specific case. This requires an integrated design approach,
where the different low energy and solar technologies to be used are
considered integral parts of the whole.

Task 23 will enable the designers to realise such integrated
design processes and to carry out the necessary optimisation
exercises, thereby ensuring the most appropriate use of solar energy
in each building project. This will be done by providing the
designers with a set of design tools.
The work in the Task focuses primarily on commercial and
institutional buildings, as these types of buildings all need more
than one type of system. In particular, office buildings and
educational buildings are addressed.
The primary results of the work will be guidelines, methods, and
tools for use by building designers in the early stages of design.
The Task also includes demonstration buildings, as such buildings
both provide an opportunity to test the design tools developed, and
as they provide an effective way of demonstrating the integration of
solar technologies in real buildings. A more elaborated introduction
to the Task can be found in the booklet
Energy Buildings and the Integrated Design Process - An Introduction.
