Abstract Washing machines have in recent years incorporated programmes that are very energy- and water-efficient, but this entails a long programme duration, often beyond 4 h. These are also the programmes that the manufactures use to define, test and declare the overall water and energy efficiency of the machines. In response to these developments, there is evidence that consumers are reluctant to use excessively lengthy programmes, even if they are aware that the programmes are more energy-efficient. This paper analyses this divergence of programme offer and programme use, which jeopardises the energy efficiency policy objectives for these appliances in the European Union (EU). The paper explores several policy measures to address this divergence, discussed in the context of the revision of the Ecodesign and Energy Labelling regulations that apply to washing machines in the EU. Three different measures are studied: the provision of information about the programme duration on the energy label, the inclusion of time as an intrinsic parameter of the energy efficiency index calculations and the setting of a programme duration cap. The paper concludes that introducing programme duration as an additional parameter of the energy efficiency index would result in the highest energy savings. However, this scenario is associated with significant uncertainties since competition among the manufacturers for a better energy label classification will not solely focus on energy efficiency aspects, and the outcome of such competition is unclear. The other two measures investigated are less effective but would also deliver savings. A programme duration cap would bring energy savings if consumers are aware of their existence and select the now shorter yet energy-efficient programmes more often. The provision of programme duration information on the energy label would also be effective but requires that consumers are able to correctly understand it.

Clinker Production

Industrial development has lead to higher energy consumption, and emission of greenhouse gases. Cement industry plays an important role in energy consumption and overall greenhouse gases emissions. This paper reviews the preceding studies concentration on the provision of energy saving, carbon dioxide emission reductions correlated with implementation of a number of technologies applicable to improve the energy efficiency in the cement industry. Energy efficiency measures for clinker production. It is found the largest amounts of thermal energy saving, electrical energy saving, emission reductions are 4.1 Giga Joule per ton, 35 kilo Watt hour per ton, 112,61 kilogram CO2 per ton respectively.

Abstract The report presents an analysis of luxury charter yachts which are a specific class of vessels that, in order to meet the schedules and increased requirements of the owners regarding the luxury of the services offered, have relatively high energy consumption for their gross tonnage, compared to other passenger ships. The study focuses on the analysis of energy efficiency of luxury yachts by calculating the energy efficiency index (EEDI). This involves comparing different parameters that affect the value of the EEDI and can lead to energy savings. The report presents theoretical and experimental studies of the energy costs of a 70-meter luxury yacht for charter trips. With the use of the design data of the ship’s electrical equipment at different operating modes, at different routes, under different conditions, dependences for analysis of the optimal modes of movement are obtained, which leads to the realization of maximum savings of electricity and primary energy.

Financing Mechanism

In financing mechanism of National Fund for Environmental Protection and Water Management it is necessary to achieve energy savings of at least 20%. However, not always achieving such energy savings means an increase in economic and ecological efficiency. Therefore, the article presents possibilities of investment leading to energy savings, reducing consumption of primary energy contained in the fuel by increasing production efficiency and reducing energy losses directly in the source. This solution will allow to keep economic and ecological savings. Proposed solutions are crucial for the implementation of investment. The improvements proposed in the article, if they have not been implemented so far, should give significant effects in all cases. The study was conducted for the medium-sized Polish company. The company can be considered as representative of food processing industry. The study was conducted on basis of energy efficiency auditing. Based on the obtained results it can be stated that the use of cogeneration, heat recovery and alternative methods of cooling at an appropriate balancing may allow the average annual primary energy saving of 563 toe/year and the reduction in CO2 emissions by 2,413 t/year. Thus achieved energy efficiency index may reach approx. 20%, eco-efficiency index may reach approx. 40% and economic efficiency index may reach approx. 30%.

This study quantified the improvement in energy efficiency following passive renovation of the thermal envelope in highly inefficient residential complexes on the outskirts of the city of Madrid. A case study was conducted of a single-family terrace housing, representative of the smallest size subsidized dwellings built in Spain for workers in the nineteen fifties and sixties. Two units of similar characteristics, one in its original state and the other renovated, were analyzed in detail against their urban setting with an experimental method proposed hereunder for simplified, minimal monitoring. The dwellings were compared on the grounds of indoor environment quality parameters recorded over a period covering both winter and summer months. That information was supplemented with an analysis of the energy consumption metered. The result was a low-cost, reasonably accurate measure of the improvements gained in the renovated unit. The monitoring output data were entered in a theoretical energy efficiency model for the entire neighborhood to obtain an estimate of the potential for energy savings if the entire urban complex were renovated.

The energy efficiency requirements of most energy-consuming sectors have increased recently in response to climate change. For buildings, this means targeting both facility managers and building users with the aim of identifying potential energy savings and encouraging more energy-responsible behaviors. The Information and Communication Technology (ICT) platform developed in Horizon 2020 FEEdBACk project intends to fulfill these goals by enabling the optimization of energy consumption, generation, and storage and control of flexible devices without compromising comfort levels and indoor air quality parameters. This work aims to demonstrate the real-world implementation and functionality of the ICT platform composed of Load Disaggregation, Net Load Forecast, Occupancy Forecast, Automation Manager, and Behavior Predictor applications. Particularly, the results obtained by individual applications during the test phase are presented alongside the specific metrics used to evaluate their performance.
