Part of the Lighting Design team at Hoare Lea, with a focus on daylight, Ruth is also a visiting lecturer at UCL, Past President of the Society of Light & Lighting (SLL) and a Board member of the Chartered Institution of Building Services Engineers (CIBSE). With a background in lighting design, engineering and academia, she has been involved in the design of buildings since 1999. Her experience includes interior and exterior lighting as well as daylighting. Prior to specialising in lighting design, she was a building services engineer for five years, which gives her a strong appreciation of the specialism in the wider context of sustainable building design. She is driven by the fact that our industry needs to step up to address the dual challenges of making buildings that work for people whilst minimising the carbon footprint of the built environment. Her PhD was about the user experience of electrochromic glazing and she is particularly interested in how we can improve the design of lighting, shading and daylighting by focussing on how real occupants experience the buildings designed. Ruth is a regular contributor to lighting guidance documents for the Society of Light & Lighting (SLL), and was principal editor for Lighting Guide 10: Daylighting. She also developed the Daylight module of the Lighting Education Trust (LET) diploma course and act as module tutor.
