The Lucerne University of Applied Sciences has been analysing and monitoring the low- temperature district heating and cooling network (LTN) “Suurstoffi” since 2012. The analysis showed that heating demand was twice as high as expected. On the other hand, ...
The aim of this work is to increase the efficiency of industrial processes by using pinch analysis and process design methods. The main goals are the reduction of energy consumption, of the corresponding operating costs and of CO2 emissions. In this contex ...

Throughout the years LENI-EPFL spent a significant part of its research activities on heat pumps be it for industrial heat recovery or for domestic or district heating and cooling. Methodological contributions include the improvement of the formulation of ...
Concern for the environment has been steadily growing in recent years, and it is becoming more common to include environmental impact and pollution costs in the design problem along with construction, investment and operating costs. To economically respond ...
Nowadays, one of the main alternatives for a more rational use of energy in heating applications is the heat pumping technologies. The market is dominated by two kinds of heat pump systems: the electrically driven vapor compression heat pumps (EHP), which ...
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. ...
A more widespread usage of heat pumps would contribute to significantly reduce both local and global environmental impacts. This is particularly relevant within cities, where advanced integrated energy systems incorporating heat pumps and associated with d ...
The Laboratory of Industrial Energy systems has evaluated a series of high performance air-water heat pump concepts with the aim to retrofit existing fuel fired boilers for residential hydronic heating systems. The results are published within the framewor ...
Providing heat pumps for the retrofit of fuel based boilers in residential heating, is a short or medium term challenge and a major opportunity for a substantial reduction of greenhouse gas emissions. While effective solutions for improved high temperature ...
A simultaneous optimization of the design and operation of a district heating, cooling and power generation plant supplying a small stock of residential buildings has been undertaken with regards to cost and CO?2 emissions. The simulation of the plant cons ...
