A fundamental requirement for a renewable energy generation technology is that it should produce more energy during its lifetime than is required to manufacture it. In this study we evaluate the primary energy requirements of a prospective renewable energy ...
This paper proposes a new point of view in analyzing the optimal Gibbs energy dissipation in growing microorganisms. Small Gibbs energy dissipation in growth would be of biological advantage because less resource is consumed and the biomass yield on these ...
In this paper, we propose a unified method for the integrated energy planning during the development of new districts for all involved actors. Taking energy related problems such as equipment choice and size, costs and environmental impact early into consi ...
Following the increased consciousness regarding global warming and other environmental issues, there is a growing urge in cities for a more rational energy supply and use in buildings. In parallel, the range of possible actions has broaden, from building r ...

Within the goal of reducing greenhouse gas emissions and supplying sustainable energy, complex integrated energy conversion systems have to be designed by taking into account thermodynamic, economic and environmental considerations simultaneously. The proc ...
In this paper, a linear tubular generator is presented. It is used for an energy harvesting system equipped in a footwear, scavenging power from forward motion during a walk. Configuration of the generator is studied, and geometric optimization by finite-e ...
In order to separate a mixture into high purity products, Dividing Wall Distillation Columns (DWCs) have shown to be, in most cases, more convenient than using conventional distillation column sequence. In fact in DWCs the entire separation task occurs in ...
Energy geostructures represent a renewable and clean source of energy which can be used for heating and cooling of buildings and de-icing of infrastructures. This technology couples the structural role of geostructures with the energy supply, using the pri ...
In the context of a semester project conducted at the LENI Lab at EPFL, a study on reactors integration and the effect of the operating conditions of the reactor and the reaction, on the T-H profile was carried out with the help of an Exergy Analysis. At t ...
This report presents a study of an enthalpy and exergy analysis in the framework of a district scale energy balance. Energy demand (heating, cooling and lighting) for buildings represents more than 30 % of the total worlds energy use. Main efforts have been ...
