How can homes, schools and offices truly support human needs? How can these buildings and others be healthy places for their occupants, while also being energy efficient, respectful of resource consumption and in balance with nature?

These questions were explored during the VELUX Daylight Symposium and VELUX Healthy Buildings Day, which were held for the first time back to back in one best-practice, knowledge-sharing event in Paris on October 9 and 10, 2019. This year the Daylight Symposium and Healthy Buildings Day provided a platform for more than 600 researchers and professionals to discuss ways forward for defining and creating healthy buildings.

The two-day programme sought to strengthen an evidence-based approach to building design. It aimed to build bridges from research to building practices so that scalable solutions can be created, and real value can be added to buildings, to the benefit of their owners, users, and society at large.

The people who design, operate and maintain our buildings have a bigger impact on our health than our doctors”

The VELUX Daylight Symposium, held every second year since 2005, is an internationally recognised event focusing on daylight research, education, practices and policymaking. The 8th Daylight Symposium maintains its broad architectural agenda related to daylight, while sharing new ground-breaking research within a like-minded community. The programme will contain a mix of invited speakers and selected submitted papers related to daylight, building performance and human health, as well as architectural case studies.

The VELUX Healthy Buildings Day, held every year since 2015, invites policymakers, house builders, building owners and thought-leaders to share and discuss how buildings impact our health and wellbeing. The 5th Healthy Buildings Day will focus on the commercial side and practical applications with architectural focus on cases with VELUX solutions. The programme will contain a deep-dive into building practices, feature a variety of building cases and address pivotal questions such as how do we create buildings that are healthy and fulfil the needs of their users and society at large.

On 9 October, VELUX Daylight Symposium invites researchers, educators and practitioners to come on stage and share their latest research and insights  related to daylight in buildings and people's lives. 

Papers are called for within the following categories:

  • Health effects of daylight in buildings

  • Human response to daylight and architectural design

  • Economic value of daylight and views

  • Densification of cities and access to daylight

  • Case studies on the use of daylight in architecture

  • Daylighting tools, metrics and regulation

  • Daylighting education and training

The one-page extended abstract should relate to the call for papers categories and be approximately 300 to 500 words. All abstracts will undergo a peer review process by the Daylight Symposium scientific committee.

Abstracts are to be submitted by email to no later than Friday 19 April 2019

The 8th VELUX Daylight Symposium and the 4th VELUX Healthy Buildings Day will be held at Le Carreau du Temple, a historically significant building in Paris. The land on which Le Carreau du Temple is built originally belonged to the Knights of the Order of Jerusalem. It was granted to them in the 12th century by the King at the time. In the Middle Ages, the Temple and fortress enclosing it became the property of the Order of Hospital, and therefore the home of the Grand Priory of France. In the 17th century, many hotels were built on the site owned by French aristocrats and bourgeoisie.

In the 18th century, the site was seized during the French Revolution and royal family members were imprisoned there until their execution. Following that, Napoleon ordered the demolition of the Temple’s tower. In its place, a covered wooden marketplace, designed by French architect Jacques Molinos, was built. It was divided into four sections, selling different items like garments, linen, carpets, leather and other similar goods.

Due to risk of fire, and as part of a push for urban renewal by Napoleon III and the prefect Haussmann, the building’s wooden structure was replaced by a cast iron and glass structure in 1863, designed by Jules de Mérindol. The new structure provided a magnificent indoor space with lots of natural light and more than 2,000 stalls for merchants. The marketplace became famous and after WWII was also used to sell second-hand clothes. Le Carreau du Temple later became known as a Mecca of Parisian clothing. In the 80’s it was under threat of being demolished for redevelopment into a carpark. Fortunately, some citizens of Paris fought for its preservation and succeeded, so that one out of the original four sections became listed as an historic monument in 1982.

In 2007, Le Carreau du Temple was closed for reconstruction yet again, this time designed by StudioMilou Architecture. In 2014, the unique building reopened as a multipurpose cultural, exhibition and event venue.


We invite all building professionals to join us in Paris to take an active role in a dialogue around vital aspects of building design. It is possible to register for either or both days of the event, as well as the official dinner on 9 October. Deadline for registration is 15 September. Register early as there is a limited number of spaces.

UPDATE: The event is sold out.
