Large lightwells to revitalise a deep office building in Lausanne

Bernard Paule

The city of Lausanne is built on fairly steep slopes, with the consequence that some buildings are leaning against what could be described as cliffs and, therefore, have only one glazed facade. The Rue Saint Martin office building has been built during the ...

Daylight and temperature in buildings: interaction effects on human responses

Giorgia Chinazzo

Over the past years, increasing efforts have been devoted to understand how people perceive the indoor environment with the goal to improve building design and operation. Studies have separately addressed the effects of the four main aspects that influence ...

Impact of dynamic lighting control on light exposure, visual comfort and alertness in office users

Jean-Louis Scartezzini, Mirjam Münch, Ali Motamed, Marta Benedetti, Lenka Maierova

The lighting environment at indoor workplaces is important not only to provide vision and visual comfort, but also for light's direct influence on human physiology, cognitive performance and mood. The purpose of this ongoing study is to investigate the imp ...

A smart luminaire in an office environment: impact on light distribution, user interactions and comfort

Jérôme Henri Kämpf

A smart luminaire able to change the direction of its light beam is installed in an office environment and compared to the available LEDs fixtures. Standard lighting measures are performed and a controlled user experiment is conducted, involving 22 subject ...
