Daylight and Shadows physical testing in the Skydome

The Vertical Studio Workshop at the University of Cardiff, has been an interesting experience for students and tutors for modelling and testing Daylight performances and Shadows into two building in scale 1:50. 

Second and First year architecture studens participated to the workshop held by Echomaterico.net(enrico@echomaterico.net) and Shan Shan Hou (researcher and PhD student at the School of Architecture). The workshop has been focused on passive and sustainable design.

The aim of the workshop was to investigate practical and theoretical issues related with passive design in dwellings. Nowadays, more than in the past, architects are asked to face a challenging scenario in which their design must communicate a responsible action taken toward a delicate and compromised environment. Providing students with multidisciplinary tools (from architecture to engineering background) will stress the importance of technical and practical aspects of the passive design. Building itself has to be perceived as a complex system structured to interact with the environment through passive and active technologies.
Students have been driven across a 3weeks design and lectures workshop culminating with the modelling and testing of two physical prototype (scale 1:50).

Measuring daylight with photovoltaic sensors allowed students to understand the behaviour of their models and to test different configurations of their facades in order to achieve a optimal natural light level.

The 10m diameter sky-dome installed in the main floor of the School of Architecture provided an amazing working space and represented a fascinating learning tool for students.
