Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict …
In today’s society a large focus is put on energy systems and how our energy systems are built up. In order to make sure that we in the future still can enjoy the living standards that we are used to today, Sweden and EU have made a number of decisions on making our energy …
… renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that …
Energy and environmental demands regarding buildings have become an increasingly discussed topic, both in Sweden and in Europe as a whole. The general trend indicates that greater efforts are being put into the energy efficiency of the built environment. There are already …
The energy that the earth receives from the sun hourly has potential to cover a year’s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case …
Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar …
Ett samarbete mellan ÅF och kund

En beskrivning av energieffektiva åtgärder i flerbostadshus och dess lönsamhet
Environmental impact and management of energy is a highly topical issue in today's society. Climate impact must be reduced. The Government has set a target to reduce energy consumption in buildings by 20 % by 2020 and 50 % by 2050 compared to the energy use in 1995. With this in …
… show that passive heat exchangers can recover about 10 ? 15 % of the hot water energy consumption, not including standstill losses and hot water circulation. Calculations indicate that the energy savings for passive heat exchangers could be 20-25 %. If several kinds of heat …
In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it’s in everybody’s interest to reduce the energy consumption and thus reduce the …
