With that in mind, exterior lighting and its function in the public realm becomes a key element of building design. The growth of the night-time economy, as well as the understanding that lighting can be not only functional, but also improve public spaces, have steered designers towards creating more nuanced after-dark environments. On page 4, we explain how lighting consultant StudioFractal which was responsible for the Kings Cross Square lighting scheme tries to replicate the range of brightness values that make us feel comfortable in daylight. To ensure a lighting narrative and encourage exploration, it has connected interior and exterior spaces at its recent London Wall Place scheme. SLLs new Lighting Handbook includes several chapters on exterior lighting design. As Paul Rufes points out on page 7, this is not just about lux, but about providing the right amount of light, exactly where it is needed. Our CPD, on page 19, explores this specialist area further, as well as other new chapters of the handbook.

Enhanced working environments, through the use of optical control and effective lighting designs, can have profound effects on worker productivity and wellbeing. Greater emphasis on commitments to sustainability and the environment are crucial to maintaining a healthy planet. We all have a role to play in moving away from the traditional consumption processes of extracting resources from natural systems and then disposing of them. Instead, sustainable practices such as designing away waste, maximising value and ensuring that materials remain within the cycle are key to achieving environmental targets and a circular economy. The SLL Lighting Handbook, updated in 2018, outlines the key ways in which lighting manufacturers, designers and speciers can enhance the solutions they provide for customers. Tamlite Lighting has developed a CPD module to take key decision-makers through the primary concepts laid out in the updated SLL handbook within this article, and a full CIBSE-approved CPD is available on request. The responsibilities of lighting go further, however. In January 2020, we will see the start of phase two of the Grenfell Inquiry, which aims to ensure such a tragedy doesnt happen again. It is the duty of everyone within the supply chain to make sure emergency lighting in all buildings is safe and up to standard, and not wait to act.
