Daylight in Buildings: 
A Source Book on Daylighting Systems and Components 

Report of IEA SHC Task 21 / ECBCS Annex 29, July 2000

This book is based on work carried out by the Solar Heating and Cooling (SHC) Programme of the International Energy Agency (IEA) under IEA�s Task 21, Energy Conservation in Buildings & Community Systems, Programme Annex 29, Subtask A: Performance Evaluation of Daylighting Systems. Subtask A�s work programme was coordinated with research carried out by the other IEA SHC Task 21 Subtasks. These included Subtask B: Daylight Responsive Controls, Subtask C: Daylighting Design Tools, and Subtask D: Case Studies.

The IEA was established in 1974 as an autonomous agency within the framework of the Organization for Economic Cooperation and Development (OECD) to implement an international energy programme. A fundamental aim of the IEA is to foster cooperation among 25 of the OECD�s 29 member countries and the Commission of the European Community in order to increase energy security and reduce greenhouse emissions. The IEA sponsors research and development in a number of areas related to energy. Within the program of Energy Conservation in Buildings and Community Systems (ECBS), the IEA is carrying out various activities to predict more accurately the energy use of buildings. These activities include comparison of existing computer programmes, monitoring of buildings, comparison of calculation methods, and studies of air quality and occupancy. The IEA Solar Heating and Cooling Programme (IEA SHC) was initiated in 1977 as one of the first collaborative R&D agreements established by the IEA. The participating countries carry out a variety of projects intended to advance active solar, passive solar, and solar photovoltaic technologies for building applications.

The main objectives of the IEA SHC Programme Task 21 and ECBS Annex 29: Daylight in Buildings are to advance daylighting technologies and to promote daylight-conscious building design. Denmark is the Operating Agent for IEA SHC Task 21. The participating countries are: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Italy, The Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, and United States.
