Daylighting monitoring protocols and procedures for buildings. A report of Task 21/Annex 29. Daylight in buildings

摘要

This official IEA report is a deliverable of IEA SHC Task 21/IEA BCS Annex 29: Daylight in Buildings. The Task focuses on daylighting systems and strategies which can be applied in new and existing buildings with a high potential electricity saving potential such as offices, schools, commercial, and institutional buildings. The daylighting performance of these strategies and systems is tested in laboratory facilities, through modeling, and in real case study buildings. This paper provides methods and procedures to evaluate the daylighting performance of real buildings. Annex 29 case studies located in Europe, North America, and Australia. It is a deliverable of Subtask D research projects. The main objective of Subtask D, as stated in the Implementing Agreement of Task 21/Annex 29, is 'to demonstrate the viability of daylighting buildings in various world climatic zones as a means of achieving significant improvements in building energy efficiency while maintaining a satisfactory visual and thermal environment for occupants'.
