UNStudio, founded in 1988 by Ben van Berkel and Caroline Bos, is an international architectural design studio specialising in architecture, urban development and infrastructural projects. UNStudio Architectural Sustainability Platform (ASP) engages all UNStudio projects from the early phases in order to ensure that the correct choices are made and that the ofce’s high sustainable standards remain an integral part of the design process. The ASP is committed to the promotion and practice of sustainable design. This involves both active and passive design tools, which have a recognizable effect on the design of the building, product or urban plan. The ASP is continually involved in the development of new tools for an improved design process. Together with the application of the many international environmental regulations and an in-house assessment toolkit, new sustainable assets are created.
Throughout the history, daylight has been a primary source of lighting in buildings. As architects and designers, we continuously work on improving quality of daylight in buildings, its aesthetics and well-being benefits. It can contribute greatly to a dynamic user experience and impact human performance. Good daylighting design can result in energy savings, shifting peak electrical demand during afternoon hours, when daylight availability levels and utility rates are high.
The aim of designing for daylight is to get as much daylight as possible deep into a building while controlling the brightness of surfaces within the users’ fields of vision.
While most of the devices encourage daylight to penetrate the building, some other systems also attempt to reduce the daylight ingress.
Depending on location and building typology, the parameters of direct and diffuse radiation and sun impact studies lead to conclusions that have influence on orientation, massing, program and envelope. UNStudio project approach is always site and climate-specific. Digital analysis of the building geometry and amount of facade openings helps to find a tailor-made solution for the building complex and its environment. All these considerations are integrated into a design approach as a holistic solution. This strengthens the concept, decreases the multitude of components and therefore reduces the costs of maintenance. UNStudio stimulates new developments of daylighting devices by digital but also physical prototyping.
Our approach to daylight in architecture is illustrated with the topics of:
The 21 story UNStudio Tower forms part of the Mahler 4 urban complex, a cluster of six buildings located in the heart of the south axis in Amsterdam.
Two main concepts are mainly shaping the building. Firstly, voids form a vertical accent and connect the inside with the outside. Secondly, horizontal articulation is provided by white, aluminium bands which wrap the tower. The voids create an inside-outside relationship which extends the façade envelope and turns the surface of the tower into an active medium with a profound effect on the quality of the interior user space. The white aluminium bands differ in size, depth and transparency ensure the correct balance of sun screening, light penetration to the interiors and facilitate the daylight via redirection devices to the ceiling to ensure deeper light penetration. Thermal glazing allows for sufficient daylight, whilst reducing direct sunlight.

The design for the Education Executive Agency and Tax Office building, accommodating 2,500 employees, reflects and caters for the separate identities of both user groups, whilst simultaneously creating synergy by means of shared use of secondary spaces – among which underground parking facilities, public gardens, a central hall and a pavilion for commercial functions.

The academic campus for the Singapore University of Technology and Design reflects an in-depth understanding of the changing requirements of learning institutions today. Connectivity, collaboration, co-creation, innovation and sociality are at the basis of UNStudio’s design thinking on New Campuses.
The SUTD is a driver of technological innovation and economic growth, with the new campus bringing together people, ideas and innovation.
