Description

Providing comfortable, healthy buildings with high energy efficiency is a key challenge for the future. Solutions that combine both safety and comfort for the occupants with sustainable approaches to address the environmental challenges have to be implemented in construction field. In this frame, new methodologies to assess the comfort of occupants have to be developed. However, if daylight is increasingly highlighted in new construction, it still represents a largely unexploited resource in existing buildings for saving energy and improving occupant’s comfort. In this context, there is a need for extensive evaluation of the comfort, based on metrics and non-intrusive diagnostic but also on human experience and perceptions. Our work is focused on the development of indicators of comfort and on setting up the associated evaluation protocols. We have developed a set of tools to quantitatively assess visual comfort in existing places. The set of tools that will be detailed are measurements and simulation of daylighting performances in a room associated to an occupant satisfaction survey. The tools combined together aim at providing non-intrusive and quick assessment of occupied spaces. The results show that the assessment tools are candidates for short to mid-term adoption of the tools outside of the research field and for internal campaigns. They are particularly adapted to post-occupancy diagnostics that can be performed by design offices in the frame of labelling schemes. Results of the measurements, simulations and surveys to assess visual comfort in an office space are described in details.
