The new IEA Task 61 Annex 77 will focus on the identification of the potentialities of strategies combining daylighting and appropriate lighting control systems to lead both

  • to very high energy-efficient lighting schemes, and
  • to solutions offering the best lighting conditions for human being.

This program will bring together, during 3,5 years, 30-40 international experts and companies, involved in dynamic daylighting and lighting and their controls.

Useful knowledge and results from research will be gathered, concerning the perception of users concerning lighting quality, human interfaces and control strategies. We will propose models of lighting controls integrating user behavior and expectations. We will identify best possible approach of control solutions for lighting and daylighting (movable components of windows), with wireless and wired controls, open loop and closed loop, IoT, etc.). We will conduct onsite and laboratory monitoring of innovative solutions and publish results to document benefits. Part of the work will lead to deliverables to be forwarded as standardization proposals, in relation to CEN and ISO.

Objectives of the Workshop

  • Task experts will inform about the new project and planned deliverables
  • Industry speakers, task experts and workshop participants will actively exchange their experience
  • Obtain feedback from industry and learn about practitioners’ needs, for successful continuation of the work within IEA SHC Task 61 Annex 77
