  • Interaction between qualitative and quantitative approaches in the teaching of architectural design In order to improve the understanding of daylighting by students in architecture, we seek a better integration between scientific and architectural languages and we try to strengthen the links between quantitative (knowledge on daylighting as a physical phenomenon expressed in mathematical terms) and qualitative (knowledge on daylighting as a modifier of luminous ambiance expressed in ...
  • Measurements and qualification of luminous ambience in daylighting This paper is centered on the relationship between intuitive and quantitative approaches for the understanding of luminous ambience in order to formalize criteria for the classification of luminous ambiences. We measured luminance and illuminance levels on glazed and opaque surfaces in interior spaces and built a synthetic scheme of these levels. We then analyzed and compared ...
  • A comparative analysis of luminous ambience designed for equivalent functions The first part of this work focused on the elicitation of links between qualitative and quantitative approaches for luminous ambience in daylighting. We measured luminance and illuminance levels on glazed and opaque surfaces in interior spaces. We analysed and compared these measures and interpretations to impressions felt by subjects in the spaces, or to intentions ...
  • Comfortable and/or pleasant ambience: conflicting issues? We present here a theoretical study about the relationships between comfortable and pleasant ambiences. The notion of comfort is not sufficient for the study and design of ambience. Ambience is defined here as the way the environment affects a subject. Subjects are naturally affected by a global ambience. However, for the analysis, we distinguish between ...
  • Dimensions of personality in the responses to luminous ambiences In this multidisciplinary work, we propose a practical framework to study the variability of subjective responses to identical luminous ambiences (atmosphere). We focus on the influence of personality dimensions. Architects build spaces for which they define functional characteristics and an esthetical concept, while considering the quality of ambiences. The success of a building depends on ...
  • Luminous ambience, quantitative/qualitative data and subjective response This paper presents several years of research in luminous ambience in daylighting. It began with works on the relationship between intuitive and quantitative approaches for the understanding of luminous ambience. We collected quantitative data from measurements of illuminance levels on glazed and opaque surfaces in interior spaces. From these measures we could build an interpretation ...
  • Measurement and interpretation of luminous ambience This paper presents part of a multidisciplinary work with three teams: two laboratories of psychology and a laboratory of lighting/architecture. We concentrate here, within the project, on activities on luminous ambience and focus on the lighting/architecture part. The problem we studied was: How is it possible to concisely express the variety of luminous ambience qualities ...
  • Simulation of Luminaires in Radiance: Verification Method In the process of architectural design architects can use different software tools for modelling and simulation. These programs allow them to simulate imaginary buildings, and verify their intentions, preferences and respect of norms, in order to bring the resulting ambience closer to architects intentions. On the other hand, programs follow strictly defined geometrical and physical ...
  • Will it really be soft and calm, my luminous ambience? The intake and distribution of natural light in interior spaces are imagined early in architectural design: placement of openings, orientations and inclinations, depth of spaces, etc. are defined during the first sketches. However, existing design aid tools are ill adapted to this early phase where the building is not completely defined. In order to help ...
  • Interpretation models and their application for luminous ambience Des mesures ou bien des simulations des ambiances lumineuses intérieures produisent de grandes quantités de données. Ces données peuvent être très utiles pour analyser la performance et le confort des ambiances lumineuses durant la conception ou la réhabilitation et pour promouvoir une utilisation contrôlée de l’éclairage naturel au lieu de l’éclairage artificiel. Toutefois, il est nécessaire ...
