A system is being designed, using solar energy in combination with Aquifer Thermal Energy Storage (ATES), that will conserve a major part of the oil and electricity used for heating or cooling the Cukurova University, Balcali Hospital in Adana, Turkey. The general objective of the system is to...

Tunisia expects a very large growth in energy demand but Tunisian' indigenous energy resources are limited. Today Tunisian' energy resources meet the total primary energy demand. In short time Tunisia will become an importer country for primary energy.

The great incidence that glazing has in a building energy conservation makes it one of the most important parameters to be taken into account especially in commercial buildings, where the surface occupied by glass areas is very important. So, different shapes of glass areas and their influence...

Pakistan needs substantial amount of energy to develop its industry and to increase the agricultural productivity. The available indigenous energy resources are limited. The only option which the country has to pursue is renewable energy. This paper identifies the potentials of solar and wind...

Polish economy is characterised by high energy intensity in all sectors. Energy used for heating purposes for municipal and co-operatives buildings is especially high. A lot must be done to reduce energy consumption. This paper presents energy conservation technologies that have started to be...

Programs regarding to energy saving in Brasil arised by the early 80's, from the concern with oil products consumption. The situation has changed and electricity is growing in importance when energy conservation is discussed.

This study is a contribution to European projects Pascool/Joule II and Altener/Sink that deals with feasibility of passive cooling systems in Europe. The first aim of this work was to define a design methodology to evaluate natural cooling potential according to the climatic quantification...

Combustibles expenditure is becoming an important part of the operating costs for public buildings, like hotels, hospitals, offices, etc. Therefore, the savings in energy are a priority for countries like Tunisia, whose oil and gas resources are just sufficient for today's needs. One of the...

The paper presents a parameteric analytical study of roof solar chimney coupled with wind cooled cavity using spread-sheet computer program. Detailed description and sizing of such system are presented. Separation between the external leaf and solar chimney's external glazing is optimized. The...

This study clarifies the law of diminishing returns when improving the conservation level of residential buildings by using case studies simulation. It explores the effect of different climates on the decision of selecting the insulation type and thickness. It shows the importance of using the...
