Lighting Consultancy

Attractive, functional and cost effective lighting from the right balance of daylighting, electric lighting and control systems.

Successful lighting depends on a balance of natural lighting (daylight and sunlight), effective and energy-efficient electric lighting and integrated control systems. These should complement the building’s design and support human activities. With experienced lighting experts and first-class facilities, we provide professional consultancy, advice, analysis, research and training on all aspects of electric and natural lighting, including occupant needs for lighting.

Lighting for new spaces

BRE experts provide impartial advice on the performance of new lighting technologies or innovative strategies, and on integrating electric lighting with daylighting.

We advise on developing the design brief and design specification, perform design assessments and prototype evaluations, and offer guidance on selecting lighting systems (light sources, luminaires and lighting controls) by evaluating their flexibility, suitability, value for money, energy efficiency, user-friendliness and maintenance costs.

Lighting in existing buildings

Our experts measure the effectiveness of current lighting systems, assess problems such as glare, flicker or inadequate quantity and quality of light, and suggest remedial measures.

We provide particular expertise on the best lighting for activities such as display screen equipment use, the appearance of lit spaces, colour appearance and colour rendering properties, impacts on user performance and wellbeing, the selection of appropriate lighting controls, and obtrusive light. Once lighting has been installed we offer and carry out occupant surveys to gather views on comfort levels and identify any problem areas.

Daylight and sunlight

We offer guidance on window design, measuring daylight, solar shading, and avoiding excessive solar heating and glare. Our experienced daylighting team helps with designing site layouts to optimise daylighting, and with issues such as the right to light, overshadowing, and the effects of trees on daylight and sunlight. We can assess daylight and sunlight for planning, including writing Environmental Statement chapters for submission as part of planning applications, offer expert witness and review services and perform Rights to Light analysis.

See our Natural light page for more details.

Lighting and health

We advise on the health effects of lighting in new and existing buildings, including daylighting or circadian electric lighting (sometimes termed human-centric lighting). We draw on the latest research in this field, and relevant codes and standards such as the WELL Building Standard and standards published by the CIE (the International Commission on Illumination).

Light pollution (obtrusive light)

Lighting installations can cause unwanted spill light to other properties or to the night sky. We assess light pollution from proposed developments and infrastructure and advise on cost-effective remedies. Our experts can provide reports or Environmental Statement chapters for submission as part of planning applications, and give evidence at planning hearings and public inquiries.

Selection of BRE lighting publications from the BRE Bookshop

First class testing facilities

Our laboratories and test facilities enable us to compare the performance of various lighting strategies, and provide experimental validation of innovative lighting solutions, including colour and illuminance evaluation. We also test downlights to acoustic standards for compliance with Building Regulations Part E and test LED fire alarm warning beacons.

Example lighting projects

Working with major retailers and businesses

Reviewing design briefs, evaluating existing lighting schemes, and implementing methods of reducing energy use while improving space appearance and user wellbeing. Assessing the market for different forms of lighting and how it will develop in the future.

Solid state lighting: overcoming the barriers

A human factors study comparing LED and traditional lamps when viewed side by side. This showed that people preferred the colour of the best performing LEDs to that of tungsten halogen lamps.

Daylight metrics

Detailed computer modelling based research investigating the daylight provision calculation methods in BS EN 17037 and providing guidance for daylighting practitioners on applying the daylight assessment methods in the standard.

People friendly lighting controls

Human factors study assessing different forms of lighting control – important in ensuring controls for LEDs are user friendly and intuitive.

Circadian lighting

Field research on the effects of circadian lighting on occupants’ health and wellbeing, linked with control schedules to identify optimal control strategies for circadian lighting so that health and wellbeing benefits are maximised.

Artificial skylights

Field research on the capability of artificial skylights to improve office work performance and productivity, as well as enhance space appearance.
