The appropriate choice of glazing in a facade depends on many factors. They include amongst other criteria: location, orientation, climatic condition, energetic efficiency, usage of the building, required user comfort, and the architectural concept. On the ...
The first step in order to comply with the European Union goals of Near to Zero Energy Buildings is to reduce the energy consumption in buildings. Most of the building consumption is related to the use of active systems to maintain the interior comfort. Pa ...
In urban areas, the use of thermal energy services is intensive and relatively heterogeneous by their nature, spatial distribution and temperature level required. In this study three concepts of district energy networks that could provide these services ve ...
The air-conditioning energy consumption, for cooling or heating, has currently a growing trend. The purpose of this work is to develop a method suitable to design optimal threedimensional building forms to reduce air-conditioning needs in a chosen location ...

This paper addresses the effect of the type of habitat on thermal comfort and energy requirements for heating and cooling for 7 Algerian cities located in different climatic zones of the country. Our choice is focused on four buildings: two traditional hou ...
This Recommended Practice conveniently gathers the basic data and techniques which help those concerned with the design of buildings and lighting systems understand and appreciate the opportunities and constraints inherent in daylighting. Daylighted buildi ...
When considering very large single-tower heliostat fields, the attenuation and spillage losses are growing with the distance to the central receiver. Therefore multi-tower configurations are modelled and investigated to find the thermo-economic optimal siz ...
Buildings account for over 40% of the energy consumption in the United States, nearly 40% of which is attributed to lighting. The selection of a fenestration system for a building is a critical decision as it offsets electric lighting use as well as impact ...
Liquid cooling has emerged as a promising solution for addressing the elevated temperatures in 3D stacked architectures. In this work, we first propose a framework for detailed thermal modeling of the microchannels embedded between the tiers of the 3D syst ...
The sun is the biggest known source of energy in our solar system. We feel its strength when it gets hot during the the day and we notice its absence during the night when we feel cold. So as to be less dependent on the sun as an energy source, we implemen ...
