"IEA Activities Towards Standartizations" by David Geisler-Moroder

Project manager & Head of the competence field daylight

Presentation from the 8th VELUX Daylight Symposium that took place in Paris on 9 October 2019. For more information please visit http://thedaylightsite.com & https://www.velux.com/veluxdaysinparis

 

IEA Activities Towards Standardizations for Daylight System Characterizations and Hourly Rating Methods Within the IEA SHC Task 61 / EBC Annex 77 “Integrated Solutions for Daylighting and Electric Lighting”, an international group of researchers and practitioners is working on the application of technical innovations in daylighting, electric lighting and controls in practitioners’ workflows. The intent is to bring the findings onto the desktops of designers by integration of approaches into widely used software tools, standards and codes, as well as design guidelines. Hereby the different design phases from conceptual up to the final design are addressed. With the BSDF daylight system characterization and the hourly calculation and rating methodology, two main open issues in the daylighting design field are targeted and prepared for standardization work. Additionally, advanced spectral sky modeling as an important basis for daylighting design considering also color and non-visual effects is covered. Currently available daylight system characterization methods have their strengths and limitations.

 

Standard glazing as the transparent part of facades can be easily characterized and included in simulation software. However, when it comes to daylight systems as needed for glare protection and daylight redirection, the situation is different. Although such advanced fenestration systems have the potential to improve the visual and thermal comfort of indoor spaces as well as to save lighting, cooling and heating energy, their radiative (visual and solar) performance cannot be described adequately by the technical data prescribed by current standards. Pre-normative work for a draft standard is done for BSDF daylight system characterization to come up with specifications for BSDF generation routines (measurement and simulation) and requirements for BSDF data resolutions based on intended applications (illuminance, solar gain, glare, …) and system typologies (screens, blinds, shades, …). In building energy modeling, hourly calculation methods have been the standard for a long time. For the evaluation of daylighting and daylight dependent electric lighting however, climate based hourly calculations have not yet found their way into standard lighting design tools as DIALux or RELUX.

 

To push the implementation of annual daylight simulations into lighting simulation software, an integrated hourly evaluation method is elaborated and proposed for standardization. This will help to comply with the new European daylight standard as well as promote the application of advanced daylight simulations in designers’ daily workflow.

 

David Geisler-Moroder achieved a master and a PhD degree in technical mathematics from the University of Innsbruck, Austria. Since 2010 he has been working as a project manager and head of the competence field daylight in the R&D department of Bartenbach. His main work and research areas include the development of simulation methods, the interface between daylighting and building physics, daylighting systems, and lighting technology principles. He is leader of Subtask C “Design Support for Practitioners” in the IEA SHC Task 61 / EBC Annex77 “Integrated Solutions for Daylighting and Electric Lighting”.
