The City

The present study investigates the effect of fixed external shading devices’ geometry on thermal comfort, daylighting and energy demand for cooling and heating in the hot and dry climate of the city of Ghardaïa (Algeria). A parametric analysis was performed by using three software: RADIANCE 2.0 and DAYSIM 3.1 for daylighting simulation and TRNSYS.17 for thermal dynamic simulation. Three shading device parameters were assessed: the spacing between slats, the tilted angle and the slats installation. The vertical shading angle “VSA” is fixed; it is equal to the optimum shading angle measured for Ghardaïa. The simulation results indicate that fixed external shading devices have a significant impact on decreasing the energy demand for cooling; however, they are unable to reduce the total energy demand since they significantly increase heating loads. It was found that fixed external shading devices remove all risks associated with glare in summer by decreasing illuminance close to the window; however, they do not improve daylighting performance in winter because of glare. We note that even if the vertical shading angle “VSA” was the same for all cases, these did not present the same thermal and luminous behavior. This is mainly due to the amount and the way that the solar radiation penetrates space.

Complex Cases

Daylighting simulation programs use different methods and algorithms for illuminance calculations in buildings. It is widely known that results of different lighting simulation programs does not have to be the same for two or more identical rooms. Hence CIE issued Technical Report 171: 2006 which presents test cases to assess the accuracy of lighting computer programs. However, these test cases are simple and the accuracy of daylighting computer programs can be different for more complex cases. The purpose of this paper is a comparison of differences in the results computed by various daylighting simulation programs for selected test cases according to CIE 171: 2006 and for more complex cases.

New Buildings

Baroque temples were developed in the context of cross-cultural influences through new territories where the climatic conditions were often opposed to those prevailing in Europe. The nature of weather differences could not be predicted with the knowledge of the era and consequently, a set of gradual and successive transformations in the typologies “imported” from Europe was produced. These adaptations were lengthy, intuitive, and not always recognizable by the Metropolitan culture. Although daylight requirements played an important role in this process and its quality in baroque temples is celebrated by architectural historians, very few daylighting simulations and on-site measurements have been developed. Therefore, a twofold result is produced: Daylighting’s beneficial effects can neither be transmitted nor reproduced in other new buildings. Consequently, we discuss in this article the results of a daylighting simulation program capable of analyzing complex baroque temples around the world and to show the implications of its environmental attitude.
