CIBSE | NEWS IN BRIEF SLL signs up to night lighting manifesto The Society of Light and Lighting has signed the Responsible Outdoor Lighting at Night (ROLAN) manifesto for lighting professionals. Other founding partners include: the International Association of Lighting Designers (IALD); International Dark-Sky Association (IDA); Illuminating Engineering Society (IES); illume; Institution of Lighting Professionals; and the Lighting Industry Association (LIA). Because the UN Sustainable Development Goals do not explicitly refer to external illumination and its multiple impacts, the founding partners of the ROLAN movement, are keen to address this in support of the SDG Goals. By following the principles outlined in the ROLAN manifesto, governments, businesses, and individuals can support the implementation of the SDG.

Lighting Guide 7 (LG7): Offices, published by the Society of Light and Lighting (SLL), also addresses uncertainty around how office space will be used in the future. Simon Robinson, of WSP, author of LG7, said: The look, feel and layout of office environments will always change to reflect the ways our lives change. The Covid-19 pandemic, however, is likely to be the catalyst for change on a scale hitherto unseen, which makes it a great time to be a lighting designer. For the first time, the guidance includes a chapter focused on embodied and operational energy. This considers the amount of energy used by an office lighting installation, and the energy and carbon used in the manufacture and distribution of luminaires and the raw materials that are used to produce them. The guidance encourages the re-use of equipment where possible. Where luminaires are not suitable for reuse as complete units, it may be possible to have new control gear fitted into existing luminaire bodies, thereby avoiding the embodied energy used in the manufacture of new components. The SLLs TM66: Creating a circular economy in the lighting industry, provides more detailed information on reusing existing equipment. LG7 and TM66 are available at www.cibse.org/knowledge This valve comes with dedicated technical support. Just like all our others. Our Technical Team is here to support your project with a collaborative approach and a Fast Track Service. So, when you need the complete valve solution none of the others will do.
