Title: Daylight in Buildings
Task Concept paper accepted: October 1993
Project definition phase: March 1994 – May 1995
Commencement date: September 1995
Completion date: December 1999
Accomplishments
Although it is always difficult to establish facts of what was the
cause and what the impact, a significant change in building design
practice has occurred over the 4-6 years duration of the Task. The
single most important result of this great international effort is that
architects and engineers have become much more aware of the importance
of daylight for good and sustainable building design.
The specific accomplishments of Task 21 should be seen as important
supportive elements for the development of a building design practice in
the IEA community towards the situation where daylight and luminance
distribution in space and building is addressed from the beginning till
the end of the design process. Among these important elements are:
- Established international procedures for evaluation of the
performance of conventional design solutions and innovative
daylighting systems as well as performance of daylight responsive
lighting control systems
- A comprehensive source book on daylighting systems and
components giving an overview of the main technologies for enhancing
penetration or improving distribution of daylight in working spaces
- A broad survey of actual design solutions in selected buildings
throughout the IEA community
- A comprehensive guide for application of daylight responsive
lighting control systems documenting the monitored performance of
available systems
- A series of user-friendly daylighting design tools, from simple
tools to be used at the early design stage to advanced tools to be
used when detailed design decisions are made at the end of the
process
- Established international procedures and protocols for
monitoring the daylighting performance of real buildings including
the assessment of users’ opinion of their working environment
- Documentation of the results of a comprehensive monitoring
program for evaluation of the energy and daylighting performance of
15 selected Case Study buildings
