Trends in China's energy future will have considerable consequences for both China and the global environment. Though China's carbon emissions are low on a per capita basis, China is already ranked the world's second largest producer of carbon, behind only America. China's buildings sector...

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...

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...

The effort to reduce the dependence on imported crude oil in Greece, after the oil crises in the '70s, has resulted, among others, in a total installed area of 3.57millionm2 solar collectors in 2007, making Greece one of the pioneers in the use of domestic solar hot water system (DSHWS) worldwide.

A double reflector hot box solar cooker with a Transparent Insulation Material (TIM) has been designed, fabricated, tested and the performance compared with a single reflector hot box solar cooker without TIM. A 40 mm thick honeycomb made of polycarbonate capillaries was encapsulated between two...

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...
