EDITOR’S COMMENT & CONTENTS Lighting that puts people and planet first


L


ighting in commercial buildings has evolved far beyond simple illumination. While energy efficiency remains a key driver, the real value of lighting lies in its ability to balance human comfort, visual appeal and environmental responsibility. When well designed, lighting enhances wellbeing, supports productivity, and contributes to sustainability goals. As Neil Raithatha, at Zumtobel Lighting (UK), reminds us in this issue, an over-reliance on numerical targets can strip away the warmth and subtlety that make spaces welcoming and inspiring. He contends lighting should be adaptable to different needs, whether it’s a hospital requiring specialised lighting for patient recovery, or a workspace that needs to support both collaborative and focused tasks. (PG28) Environmental sensitivity also plays a growing role in good lighting design. Glamox’s case study in Market


Bosworth demonstrates how outdoor lighting can protect local biodiversity, preserving dark skies for bats and nocturnal wildlife while still ensuring safety and visibility. This kind of design reflects a deeper understanding of how lighting interacts with both people and ecosystems. (PG26) Meanwhile, Ansell Lighting’s warehouse project in London shows the power of intelligent controls and adaptable solutions to improve comfort and efficiency in industrial settings. (PG 30)


And when it comes to safety, Collingwood Lighting offers vital guidance on maintaining robust emergency lighting systems. (PG24) Other features this month include Domestic & Commercial Heating, Low Carbon Solutions, and Energy Efficiency.
