Significance of View Direction in Simulating Circadian Potential of Architectural Spaces

Sharon Jane Gochenour

This research paper aims to simplify the question of how to take human movement into account when assessing the lighting conditions of a space. For a person working at a desk throughout the day doing paper-based or screen-based tasks, if it is assumed that ...

Advanced Control of Electrochromic Windows

Nicolas Morel, Nikolaos Zarkadis

In our research we use the technology of electrochromic (EC) glazing to maximize the use of daylight and minimize the energy consumption in buildings while preserving visual and thermal comfort of the users. We propose an advanced automatic control of EC w ...
