SLL: LightBytes 2021 – Online

.

.

The Society of Light and Lighting is pleased to announce a brand new SLL LightBytes Online series for 2021:

You can have it all: Minimum Energy, Minimum Resource, Maximum Comfort.

.

.

You can have it all – new SLL LightBytes series paves the way for minimum energy,
minimum resource, and maximum comfort.


Beginning on 07 April 2021, this weekly webinar series will see expert speakers delivering
bite sized CPD presentations, focusing on a more sustainable approach for the lighting
industry. It aims to inform and challenge current practice, considering the implications of
delivering a quality lit environment in a net-zero carbon landscape.


This four-part series will explore methods of addressing the unavoidable need to pursue a new approach to lighting, considering manufacturing, design, installation, maintenance, and
waste.

The Society will be joined by expert speakers from its Sponsors in Partnership; Steve
Shackleton FSLL, Lighting Applications Manager at Fagerhult UK; Helen Loomes FSLL,
Innovation Akadamie at Trilux Group; and Tim Bowes MSLL, Head of Lighting Application at
Whitecroft Lighting.


The first three sessions will see the speakers delivering peer reviewed, CPD presentations,
followed by interactive Q&A. For the fourth and final session, they will be joined by Emilio
Hernandez, Lighting Designer and Chair of the GreenLight Alliance and Mark Ridler, Head of
Lighting and non-Exective Director at BDP, who will be discussing the actions they are
taking to raise awareness and initiate a circular economy approach across the industry and
within their practice as designers.


Sessions will be chaired by current SLL President, Bob Bohannon FSLL, who has been
instrumental in the ongoing development of a new SLL and CIBSE Technical Memorandum
and Circular Economy Assessment Method (CEAM), alongside the Society’s Education
Committee Chair, Kristina Allison CEng MCIBSE MSLL.


The series will begin with a focus on minimising energy use, offering additional
considerations relating to design approach; utilising the space and surface reflectance; lighting controls; and modular lighting, exploring how increased flexibility and customisation
could lead to a reduction in energy use whilst providing increased comfort for the end user.


From there, speakers will be considering resource. The second session will look at the
Repro-Light project, aiming to develop re-usable and reconfigurable parts for LED
luminaires, reducing waste and extending their useful lifetime. It will consider the potential for
nano-optics and the positive impact of reducing the overall size of luminaires. Finally, there
will be an in depth look at Cradle to Cradle certification, highlighting the social and ethical
responsibility outlined by circular economy practice, with examples and case studies.


With the need to reduce the amount of energy consumed by lighting, there is concern that
the quality of the lit environment has become a secondary consideration. The third session
will aim to build on the previous presentations relating to minimum energy and minimum
resource, whilst still providing maximum comfort. It will look at defining ‘good lighting,’ what
this would look like and the challenges it might raise in relation to reduced energy use.

With the revised BS EN 12464 now at the approval stage, this session will look at increased
awareness and consideration of the varied needs of individual occupants within a space;
providing individual control over their lit environment; and considerations for the non-visual
effects of light in relation to health and circadian entrainment. This will be continued with a
look at the new Double Dynamic Lighting concept, developed in association with Aalborg
University in Denmark.


Encapsulating the aims of the new series, Bob Bohannon FSLL commented;
“So as not to be constrained by a blinkered, energy only approach, we need to understand
and communicate all the aspects that make up better (lighting) in a net zero carbon building
.”


Registration for the new series is free for members of the SLL, with a nominal registration
fee for non-members to join all four sessions and access the recordings on demand. All the
presentations are peer reviewed, providing access to 6 hours of CPD content.

Weekly sessions will run from 07 April to 28 April 2021, from 11:00 – 12:30 GMT.

Find out more about what will be covered in each session below.

Session One: Minimum Energy

– Alternative considerations for reducing energy use, understanding the space and utilising surface reflectance to your advantage
– Utilising design and lighting controls to maintain quality
– Modular lighting – exploring how increased flexibility and customisation could improve comfort for the end user

Session Two: Minimum Resource
– Repro-light, the European lighting project to develop re-usable and re-configurable parts for sustainable LED based light systems, transforming the European LED lighting industry and what this means for the UK
– Nano-optics – looking at the potential positive impact of a reduction in luminaire size and weight 
– Cradle to Cradle Certification – the social and ethical responsibility outlined by circular economy practice

Session Three: Maximum Comfort
– Understanding what is meant by good lighting, with reference to current standards and WELL V2
– Practical guidance on meeting the requirements outlined in BS EN 12464: 2011 and what to expect from the revised edition which is currently under approval
– Exploring visibility, motivation and entrainment, with reference to the concept of Double Dynamic Lighting

Session Four: Circular Economy Round Table with guest speakers, Emilio Hernandez and Mark Ridler
Emilio is a Lighting Designer and Chair of the GreenLight Alliance, a new organisation with a mission to move towards a more circular economy.
Find out more about the GreenLight Alliance in this recent article by Emilio, featured in Arc Magazine. 

In his role as Head of Lighting for BDP, Mark Ridler decided that 2020 would be the year of the circular economy for his design team. Following a period of research, discussions with stakeholders, they set about developing and changing their design process and specification to make some concrete contributions.
You can find out more about what this process involved and the work that went into it by reading Mark’s article for SLL Light Lines.

Chaired by the Society’s President, Bob Bohannon FSLL, this session will aim to generate debate and to provide somewhat of an overview of the current activity around circular economy and developing more sustainable practices for the lighting industry and beyond. It will reference current development of the new SLL Circular Economy Assessment Method (CEAM) and Technical Memorandum.
