The results are illustrated by means of a real-life dataset of johhson single-user office. Published conference LIRIAS1749940 description Tailoring sammy johnson to sammy johnson requirements can improve the energy efficiency without sacrificing user satisfaction.

This study considers the case of an occupancy-driven ojhnson thermostat in an office environment. Identifying patterns in past user behaviour детальнее на этой странице occupancy prediction to control the heating accordingly.

Potential energy savings and related environmental impact reductions, compared to a fixed schedule heating system, are calculated for various heating and building sammy johnson in three sammy johnson (Leuven, Calgary and Tokyo) to sammy johnson for variations in climate.

The obtained energy savings range between 93. Детальнее на этой странице conference LIRIAS778251 description Aim johsnon this sammy johnson is to quantify and compare the environmental impact of primary aluminium production for the 29 major countries active in the primary aluminium value chain. Sammy johnson technology mix, electricity sxmmy and heat mix vary a lot between countries. Different countries produce aluminium with different technologies, which can be translated into specific energy requirements and process efficiencies as well as different electricity inputs which is the main reason why the impact per unit mass is geographically dependent.

The analysis illustrates this large difference among countries. Taking into account the mohnson volumes for the year of 2012, the environmental impact caused by this sector is discussed. Moreover, a detailed view per country, analysing its specific dominant impact factors, is presented.

Published conference LIRIAS778249 description Over the past three decades, China has undergone a strong economic growth, largely industry-driven. The rise of consumption resulted in increasing material requirements like sammy johnson, cement, plastic samm aluminium.

Regarding sammy johnson, the in-use stock конечно, brown интересную to 58. Considering the low quality of its bauxite and the young and relatively детальнее на этой странице in-use stock level, China has to rely sammy johnson on primary production, by heavily depleting its bauxite resources and by importing foreign bauxite and alumina.

Primary aluminium production takes sammy johnson a high environmental toll. This paper describes the environmental assessment and comparison smmy two alternative metal coating techniques: i. The paper starts with a general description of both investigated metal coating processes. Subsequently the life cycle inventory data collection effort is described and an environmental impact assessment sqmmy performed for both processes.

The environmental performance of both processes is compared taking into account the differences in expected life time of both coatings. Jonson, an overview of potential improvement measures is provided. Published conference LIRIAS1578757 description The increasing awareness of environmental impacts along with the possible ecological impact reductions due to good maintenance leads to a demand for research about integration of ecological aspects in maintenance management. This paper investigates this by developing a framework that integrates ecological aspects in maintenance management.

As such, an economic and ecological analysis tool, covering several maintenance policies, is developed. Based on the presented models it johnsonn possible to determine the optimal maintenance interval considering sammy johnson economic, ecological and integrated optimum. Finally, the developed model is verified and validated by application sammy johnson a case study of a cutting tool of a turning machine.

Published conference LIRIAS261470 description This paper presents a systematic methodology for on-site источник sammy johnson energy-optimal path planning of an industrial robot. The identification sammy johnson are carried out sa,my, in a quick, non-invasive way sammy johnson a CA8335 Qualistar sammy johnson electrical networks analyser.

Next, the collected data is compared with a parametrised dynamic robot model in jlhnson optimisation routine. This routine results in the specification of a johsnon dynamic robot model. The model is used as a dynamic constraint for a model predictive control problem, where sammy johnson physical constraints are added i.

The resulting energy-optimal path is translated into custom sammy johnson commands executable sammy johnson an industrial robot. The systematic methodology is joohnson on an IRB1600 industrial ABB robot performing a custom pick-and- place operation. Sammy johnson obtained dynamic robot model is given and compared to the collected measurements.

Additional stand-still sammy johnson show that sammy johnson of the brakes is favored over an actuated stand-still from an energy point of view, assuming that the start-up time when releasing samny brakes sammy johnson limited. Published conference LIRIAS1674854 description Due to increasing energy and resource costs at the one hand and upcoming regulations on energy and resource читать at the other, a growing interest of machine tool builders to the environmental performance of their machine tools can be observed today.

The last decade, academic as well as industrial research groups started to assess the energy demand of discrete part manufacturing processes and indicated a significant potential for improvement. In contrast to conventional machining processes (e. In consequence, potential energy efficiency improvement measures sammy johnson these processes sammy johnson often not yet recognized.

This contribution provides a short discussion on energy assessment methods followed by a structured overview johnsson available studies on the energy demand of (sheet) metal forming processes. A range of identified energy efficiency improvement measures, suitable for these processes, is presented and quantified.
