Daylighting for buildings and people

During the last 20 years, the importance of daylight within the built environment has become a key aspect of building design.

As well as saving energy and making buildings more sustainable, daylight exposure has a positive impact on the productivity, health and well-being of building occupants.

Professor Mardaljevic is an acknowledged world leader in daylight modelling, and studies both the visual and non-visual effects of daylight exposure. In 2010, he was appointed UK Principal Expert on Daylight for the European Committee for Standardisation, and in 2012 the Society of Light and Lighting presented him with its prestigious Lighting Award.

In 2005, he published a proposal for a radically new way to evaluate the daylight provision of buildings. Last year the Education Funding Agency incorporated it into the Priority School Building Programme – any tender to build schools has to abide by the proposed measure. This is the first significant change in standards for daylight in over half a century. Professor Mardaljecvic is currently leading a proposal before the European Committee of Standardisation to advance the basis of daylight evaluation in buildings across the EU.

In 2005-6, the Art Students League (New York) sought Professor Mardaljevic’s expertise to assess the impact of a proposed sky scraper on natural light in the building’s historic studios. The new measures formed part of the legal agreement for the development of the site – a world first.

The National Trust is now keen to use the simulation framework to fully explore the detrimental visual effects of daylight on fabrics and paintings within its heritage buildings. And advanced glazing manufacturer SAGE Electrochromics has commissioned Professor Mardaljevic to write a White Paper showing that it is possible to provide neutral daylight illumination for critical viewing of art objects using variable tint glass.


  • The UK Government has incorporated the framework in to the Priority School Building Programme, ensuring that all building designs for classrooms follow this framework regarding daylight
  • The European Committee of Standardisation is looking at updating daylight standards across the EU
  • The National Trust is interested in using the simulation framework to examine the detrimental effects of daylight on fabrics and paintings
