The environmental concern, ensuring comfort for occupants, pushed us to search for the impact of glazed loggia on thermal comfort of adjacent space in Cons tantine climate, having s trong climatic cons traints. An experimental s tudy is undertaken and described in this paper. Analysis of the in situ results is also discussed. This work shows that in winter glazed loggia benefit largely from sol...

Manipulating the flow of energy in nanoscale and molecular photonic devices is of both fundamental interest and central importance for applications in light energy harvesting optoelectronics. Under erratic solar irradiance conditions, unregulated power fluctuations in a light-harvesting photocell lead to inefficient energy storage in conventional solar cells and potentially fatal oxidative dama...

A passive solar tracker and concentrator device must be able to effectively concentrate solar radiation into a constant area throughout the day, without any mobile mechanism. The objective is to achieve 1000 °C on the receptor area with concentrated solar energy, and to accomplish this target a compound Fresnel lens has been designed. Utilizing multidisciplinary CAE software, an integrated mult...

<p>Solar trackers are support platforms that keep photovoltaic panels facing the sun by following from dusk to dawn. There exist active solar make use of motors and gears orientate towards sun; passive operate through differential heating fluid in tracking rack follow sun. Passive suffer lack a night return mechanism slow wake-up response mornings due limitations on surface inclination an...
