General Information

Main field: Energy-efficient and Environmental Buildings.
Compulsory for: MEMB1
Language of instruction: The course will be given in English


This course aims at introducing key concepts about human vision, visual perception, non-visual effects of light, photometry, lighting calculations, measurements, physical light modelling and simulation tools. The course provides an overview of key design principles and strategies for successful daylight utilisation and integration in building design and with the electric lighting system. The course will also explain components of daylight systems as well as electric lighting installations and principles of energy efficient architectural lighting design.

Daylighting a building describes the conscious effort to admit natural light into a building. The objectives for doing so are manifold, ranging from a desire to create healthful and stimulating spaces to efforts to reduce energy use for electric lighting and cooling. Integrated with electric lighting, daylighting is an essential component of a good and healthy indoor environment.

The history of architecture has shown that light is a determining element of architectural creation. However, the development of electric lighting and cooling systems in the 1930s transformed the fundamental role that natural light traditionally played in the design of architectural spaces. This development allowed designers to isolate the built form from natural light considerations. Today, it is possible to build spaces without any transparency (or without any opacity!). These technological transformations have also modified the role of the architect as the Master of the luminous character of architectural space. Today, numerous architects rediscover the formal possibilities of natural light as a key aspect to integrate in sustainable, healthy building design.

The interaction of daylight and building form is also an important contributor to the aesthetic experience of a space and daylighting holds today an established position within architectural practice and education. Also, it is important to understand that design decisions regarding openings (size, orientation and properties) not only affect daylight quality and quantity in a space and the resulting electric lighting consumption: they also have a definite impact on heating and cooling loads, thermal comfort and the natural ventilation potential in a space. A versatile lighting and shading solution is essential to ensure a good balance between indoor thermal comfort and natural illumination.

This course will address predominantly topics related to daylighting buildings. However, key issues related to the planning and calculations of electric lighting installations including daylight-electric light integration will also be covered in depth.
