Sustainability
The diversity of energy efficiency appliances existent on the market, with all its different issues, contributes to the existence of several tradeoffs (e.g., energy and water consumption vs. initial investment), which make the consumer’s choices in the market difficult. This becomes even more relevant, by knowing that nowadays a consumer tries to get a solution from the market, with a good compromise between the economic, social and environmental dimensions, and according to its priorities and specific needs, which can be different from other consumers. By adopting a multicriteria approach, combined with an optimization technique, based on evolutionary algorithms (EA), it will be possible to provide a set of sustainable solutions from the market to the consumer, that respects the compromise referred before. In this work, it will be presented an approach to support a decision-agent (DA) (consumer), by performing a set of sustainable choices based on electrical appliances, from the ma...
Increasing world energy demand is resulting in degradation of environment causing global warming, ozone layer depletion, climate change and exhaustion of our nonrenewable energy resources. This paper reviews different studies about energy consumption in residential buildings and different variables influencing the energy consumption. This paper also reviews the potential and challenges uprooting in the usage of renewable energy sources. The payback period in a residential building varied from 213 days to 502 days for 3BHK dwelling and 213 days to 556 days for 2BHK Dwelling if various appliances are replaced with energy efficient ones. Replacing the lighting appliances came out to be most economical in respect of the consumer, while if TV, Fan and Light are replaced, the initial cost increases but reduction in energy consumption is considerable. This study shows retrofitting of old buildings, energy conservative behavior of occupants, motivating and educating people for the use of renewable energy sources and use of energy efficient appliances are found to be the most efficient steps to reduce overall energy consumption by residential building sector.
Electrical Energy Conservation of Home Appliances
Different forms of energy are used for the industrial, commercial and day to day activities.Out of all forms of energy, electrical energy is most important one as it can be generated efficiently, transmitted easily and utilized ultimately at a very reasonable cost. So the present society has become very much dependent on electrical energy. As a result the demand of electrical energy is increasing day by day. In case of generation of electrical energy we are very much dependent on the conventional sources like coal, diesel, natural gases etc. The conventional sources have limitations in availability. As we are not so much dependent on the renewable sources like sun, wind, water etc, the shortfalls of electrical energy has already started. Though we have started to use renewable sources to generate the electrical energy, there are some limitations like high initial cost, efficiency, availability etc. The improvement of those parameters is in research level. Under these circumstances we can only reduce the consumption of electrical energy. If we can reduce our unwanted usage of electricity we can enlarge the life of conventional sources.
Improvement of energy efficiency of a small household appliance
Energy efficiency improvement of household appliances is an important environmental and economic problem in the European Union (EU). Mechanism to implement measures for improvement of energy efficiency is the labeling of these appliances. From a consumer perspective, important consideration for the purchase of new appliances is that they are energy efficient. From the perspective of traders, the labels for energy efficiency impact on sales volume. In recent years there has been increasing interest in countries outside the EU to improve the energy efficiency of small household appliances. In this regard is proposed a system for measuring and adjusting the process parameters of small household electrical appliance in terms of improving its energy efficiency.

The promotion of energy efficiency has been at the forefront of the energy policy agenda. New technological inventions and increasing environmental concerns related to contemporary energy policy are the main drivers of the adoption of more energy‐efficient appliances in the domestic sector. Additionally, the mandatory star labeling program and incentive design mechanisms are also raising awareness and motivation for their use, thus contributing to the reduction of energy consumption and greenhouse gas emissions. Sustainable energy policies generally pursue programs aiming for energy efficiency among domestic appliances. In India there are currently nine domestic electrical appliances/end‐uses certified with star labeling programs, in particular lighting sources, refrigerators, air conditioners, water heaters, televisions, computers, washing machines, ceiling fans, and water pumps. This study reviews main issues affecting selection of energy‐efficient technologies in India's dome...
Energy Efficient Appliances for Low-Income Households
2015
The EU Directive on energy labelling of household appliances (Directive 92/75/EC) and its revision (Directive 2010/30/EU) are quite successful in helping households choose energy efficient products (http://www.measures-odyssee-mure.eu/public/mure\_pdf/household/EU12.PDF) and in motivating the industry to invest in energy efficient product design. Purchasing energy efficient appliances is, however, dependent on financial capacity, as energy efficient appliances are still expensive. Low-income households very often use second-hand appliances which are old and less efficient which implies a high potential for energy savings. So, the above mentioned directive is only one factor in the expansion of the energy efficient appliance market, bringing the products into households. Another factor is the introduction of policy programmes which support the investment in energy efficient appliances. In the context of a research project, the framework of conditions for such a programme for low-income households has been identified. First of all, it was examined which household appliance could most effectively be funded. It turned out that a replacement programme for refrigerators is the most promising. The supporting and inhibiting factors which influence the acceptance and the success of a replacement programme for refrigerators for low-income households were identified. For the analysis the existing international policy programmes which aimed at low-income households were screened and insights from group discussions with the target group and with stakeholders such as manufacturers and municipals were gained. We concluded that the funding of a replacement for an appliance alone does not guarantee the saving of energy; some boundary conditions also have to be considered.
Using Evolutionary Algorithms to Achieve Sustainable Solutions through Household Appliances
Journal of Modeling and Optimization
In order to reach a sustainable planet, there is a permanent need by the consumer (decision- agent), to achieve sustainable solutions, with its decisions. Given the importance of the buildings, as a sector to achieve such solutions, as well as the diversity of household appliances existent on the market, with all its different issues, there are several tradeoffs to consider (e.g. energy and water consumption vs initial investment), which difficult the consumer’s choices from the market. The problem increases, since nowadays, the consumer tries to get a solution from the market, with a good compromise between the Economic, Social and Environmental dimensions, and according to its specific needs, which can be different from other consumers. By considering a multicriteria approach, combined with an optimization technique, based on Evolutionary Algorithms (EA), it’s provided a set of sustainable solutions from the market to the consumer that respects the compromise referred before.
