The heating and cooling of buildings worldwide represent a large amount of the energy needs and are one of the significant sources of CO2. Decreasing the environmental impact of residential and office buildings is of crucial interest. Energy geostructures ...
District energy systems can potentially decrease the CO2 emissions linked to energy services, thanks to the implementation of large polygeneration energy conversion technologies connected to buildings over a network. To transfer the energy from these large ...
The aim of process integration is to increase the efficiency and to reduce the energy consumption, operating costs and CO 2 emissions of an industrial process. The proposed methodology is applied to a real case study of a cheese factory with non-simultaneo ...
This report present the heating and cooling system integration applied in the GLN area, based on a proposed district cooling/heating network design methodology. The cooling load is provided by a mix of direct cooling and refrigeration. To improve the total ...
The behavior of a pile subjected to thermo-mechanical loadings was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. A pile situated in a building under construction was equipped with a chann ...
Large scale energy storage may play an increasingly important role in the power generation and distribution sector, especially when large shares of renewable energies will have to be integrated into the electrical grid. Up to now pumped-hydro is the only t ...
Process integration methods allow one optimizing industrial processes. The main goals are decreasing energy demand and operating costs as well as reducing pollutants emissions. High fuel costs promote installations of heat pumps. In a heat pump, process wa ...
Groupe E a promoter of district heating networks was confronted with the possibility of building a network of this nature in the municipality of La Tour-de-Peilz. The munici- pality imposed a situation where the lake water should be used for heat pumping. ...
Energy storage systems are becoming more important for load leveling, especially for widespread use of intermittent renewable energy. Compressed air energy storage (CAES) is a promising method for energy storage, but large scale CAES is dependent on suitab ...
This paper presents a methodology aimed at improving the energy efficiency of a brewery applying process integration techniques. The different steps of the analysis are presented. The first step is the identification of the process energy requirements and ...
