SHC Task 61 is a collaborative Task with IEA EBC Annex 77. Participants are working to create and develop strategies combining daylighting and appropriate lighting control systems to lead to:
- very high energy-efficient lighting schemes, and
- also to solutions offering the best lighting conditions for human being.
This programme 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 con-trols integrating user behaviour 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.
The overall objective of the activity is to foster the integration of daylight and electric lighting solutions to the benefits of higher user satisfaction and at the same time energy savings. This can be subdivided into the following specific objectives.
- Review relation between user perspective (needs/acceptance) and energy in the emerging age of “smart and connected lighting” for a relevant repertory of buildings.
- Consolidate findings in use cases and “personas” reflecting the behaviour of typical users.
- Based on a review of specifications concerning lighting quality, non-visual effects as well as ease of design, installation and use, provision of recommendations for energy regulations and building performance certificates.
- Assess and increase robustness of integrated daylight and electric lighting approaches technically, ecologically and economically.
- Demonstrate and verify or reject concepts in lab studies and real use cases based on performance validation protocols.
- Develop integral photometric, user comfort and energy rating models (spectral, hourly) as pre-normative work linked to relevant bodies: CIE, CEN, ISO. Initialize standardization.
- Provide decision and design guidelines incorporating virtual reality sessions. Integrate approaches into wide spread lighting design software.
- Combine competencies: Bring companies from electric lighting and façade together in workshops and specific projects. Hereby support allocation of added value of integrated solutions in the market.
