Valorisation of the one patch sky and sun simulator (in collaboration with the BBRI) |
The sky and sun valorisation project was funded by the Walloon
Government (DGTRE, Energy Division). It began on May 1, 2003 and finished
on July 31, 2004. Research objectives: The sky and sun simulator, built with the CSTC, helps the architects
to evaluate the daylighting quality of their project. |
|
Four tasks were carried out: Task 1 : Validation of the results obtained under the artificial sky:
Task 2 : Work on materials
Task 3 : Work on human aspects
Task 4 : Training of the architects and dissemination of results

Projet MACONSOL |
Research objective:
The project MACONSOL (control of lighting consumptions by the integration of the daylight) aims to quantify accurately the lighting consumptions when electric lighting management systems is linked to daylight availabilities. This consumption quantification is possible from measurements carried out in laboratory on scale models or from simplified methods. The developped tool will calculate the lighting internal gains and the lighting annual consumptions that would be used in the future energy regulation and/or the thermal simulation programmes. This project is financed by the Walloon Government, DGTRE, Energy division. It began on August 1, 2004 and will finish on July 31, 2006. Valentine Gilbert (valentine.gilbert@uclouvain.be) is in charge of this project. |

Cette tâche a pour objectif principal de faire de l'éclairage naturel la solution typique et préférée pour éclairer les bâtiments du 21ième siècle en intégrant le comportement humain par rapport aux systèmes d'éclairage et d'ombrage. Objectives This Task seeks to make daylighting the typical and preferred design solution for lighting buildings in the 21st century by integrating human response with the application of daylighting systems and shading and electric light control strategies. Two key issues, which require research to accomplish energy savings, have been identified as: - The determination of occupant response towards the luminous and thermal environments in buildings using daylighting systems and daylight responsive controls. - The integration of daylighting systems, electric lighting, and shading controls taking into account occupant response in order to optimise energy savings. A third objective is to ensure transference of the results to building design professionals, building owners, and manufacturers. The Task will focus on commercial buildings, both new and existing, including office, retail, and institutional buildings such as schools. To find a solution to these issues, fifteen countries and 24 institutions in Europe, North America, Asia, Australia and New Zealand are collaborating in worldwide research. The IEA 31 task is divided into 4 subtasks: A - User Perspectives and Requirements

Participation of "Architecture et Climat" The research team "Architecture et Climat" chose to participate to the subtask A which is comprised of the following projects: Project A1: Literature survey Outcomes Practical methods to assess visual and thermal indoor environment comfort
systems. Few tools are available to help designers meet the need of building
in daylit spaces.
