Ruth Kelly
Waskett PhD CEng MCIBSE FSLL

Ruth is a lighting consultant with a background in engineering, lighting design and academia. She’s passionate about the role of daylight and sunlight in bringing buildings to life, and the impact of daylight exposure on the health and wellbeing of building occupants.

Ruth worked as a mechanical building services engineer before specialising in lighting, giving her an appreciation of the key part played by lighting and daylighting in the wider context of sustainable building design. Ruth’s PhD research looked at the user experience of smart tint-able glazing in a UK office, and she has a particular interest in the real-life issues associated with automated building technology, particularly those that offer daylight control. At Hoare Lea, Ruth leads the Daylight specialism within the Lighting team.

Ruth is President of the Society of Light & Lighting (SLL), a part of the Chartered Institution of Building Services Engineers (CIBSE). She led the revision of the SLL Daylighting design guide in 2014 and is a regular contributor to various CIBSE and SLL guidance documents. She is also a visiting lecturer at the Bartlett School, UCL, with involvement in the MSc in Light & Lighting and MEng in Architectural Engineering.
