CIBSE JOURNAL LIGHTING SPECIAL LETTING IN LIGHT AT THE NATIONAL PORTRAIT GALLERY CALCULATING EMBODIED CARBON IN LIGHTING Glacial beauty Juxtaposition of light and steel creates stunning backdrop to Norwegian rest stop December 2023 | www.cibsejournal.com | Sponsored by CIBSE Dec 23 pp31 Cover Supp.indd 31 24/11/2023 13:42 Lighting innovations In the dynamic field of lighting design, it is crucial for industry professionals to stay abreast of exciting technologies and sustainable practices. Circular lighting has taken centre stage recently, incorporating environmental and life-cycle analysis into design. CIBSEs TM66: Creating a circular economy in the lighting industry is an accessible toolkit for assessing the circularity of luminaires (see page 33). There is also growing recognition of how control systems are now integral to lighting schemes, enhancing energy savings and wellness, as highlighted in the updated LG14: Control of electric light (page 34). New methodologies for preserving lighting quality and reducing energy use must be embraced. A project at the National Portrait Gallery in London used advanced lighting control techniques to reintroduce daylighting into the gallery without causing damage to the exhibits (page 40). It is an example of how natural light can be harnessed to lower both operational and embodied carbon. Combining natural and artificial light, an award-winning lowenergy lighting scheme in Norway has created a stunning building inspired by the surrounding landscape (page 38). Molly Tooher-Rudd, junior reporter for the CIBSE Journal CONTENTS 33 Navigating the circular maze How new CIBSE/SLL circular tools can be used on the path to sustainability.

Max Fordhams Nick Cramp highlights the benefits Taking the circular stage Light2Perform takes place as part of Build2Perform Live this month, and Tamlite Lighting is headline sponsoring again. We have our own presence at the two-day event, centred on two of the most significant drivers for change impacting the lighting industry: building competence levels in the design and specification of emergency lighting; and CIBSEs TM66 Creating a circular economy in the lighting industry. TM66 is central to Tamlites focus on sustainable solutions. By actively participating in the TM66 scheme, we are demonstrating our commitment to advancing the adoption of environmentally friendly practices in the lighting industry. The aim is to assist consultants and specifiers to make informed choices when it comes to selecting sustainable luminaires. We are delighted to support Light2Perform, which is a vital platform for lighting professionals to build their understanding of circularity, responsible specification and good practice. With a focus on tools for sustainability, it is the perfect event to explore TM66, which has emerged as a groundbreaking initiative within the lighting industry by promoting circularity and sustainable practices. In providing a standardised framework for verifying the circular credentials of lighting products, TM66 enhances transparency, credibility and trust within the industry. Tamlite Lighting is a founding member of the TM66 Assured Beta team for circular economy luminaire assessments. Join us as we deliver two important CPDs at Light2Perform Towards a circular economy for luminaires and Common pitfalls with emergency lighting compliance.
