Utredning av åtgärder för ventilation, värme och kyla
… for the different areas have been divided into two different parts, electricity- and heat consumption. Electricity consumption is roughly 500 MWh per year and the heat consumption is around 1020 MWh per year. This is only the consumption of the areas that have been investigated …
… inhabitants, a great number of different heating/cooling customers and 40,000 electricity customers.In the future, it will be required by HEM to integrate intelligent energy solutions, where energy consumers are increasingly micro generation and able to control their energy …
… main areas is made. Primarily the photovoltaic system is sized based on the electricity consumption in the buildings. Furthermore an assessment is made whether or not the photovoltaic system is a profitable investment. Lastly a comparison between the output of the analysis and …
En kvantitativ studie gällande hållbara uppvärmningsalternativ på en skärgårdsö
… cottages used for overnighting. The cottages now run solely on direct electricity, both for heating and hot water. The purpose of this report is to survey the current energy use of the four cottages with respect to the environmental effect and to propose alternative heating …
jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
… other with non-pasteurized substrate. For the present pasteurization system, electricity and heat demand was surveyed. For the integrated thermophilic sanitation, a process design was developed and dimensioned and the electricity and heat demand was calculated. Thereafter, the …

En studie med syftet att lösa energibehovet för ett specifikt hus.
… to assess as to its environmental impact. This due to the fact that it uses electricity as fuel. This electricity is hard to predict the source of. If the source is renewable it could be argued that the heat pump is the most environmental positive choice. If the source on the …
Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid. One way to …
In electricity markets evolving towards liberalisation and internationalisation, green certificates are seen as an important tool to promote production of renewable energy. In a green certificate market producers sell certificates received per unit of electricity generated from …
- En studie av teknik-, ekonomi- och miljöfrågor
… the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented …
… of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner. The purpose with this rapport was to do a basic study for the specific system at Arvika where it’s possible to see the potential production of electricity that …
… months, when the climate demands our houses to be heated, the relation of 8 % electricity and 90 % heat is very suiteble. Unfortunatly problems can occure during the summer time when we do not need to heat our houses. A result of producing electricity is heat. When wanting …
… Using regression analysis, the authors test for correlation between the electricity prices and the basic industry, defined as the pulp and paper industry, the mining industry, the steel and metal industry and the basic chemical industry. Moreover, five variables found in the …
… the night. 27 stores did not know if their electrical company provided ”green electricity”. Results showed that there is a lot of work to be done in making the stores more environmentally friendly. Changes do not have to be great, however all changes can help protect the …
… for utilization of the biogas werealso compared through LCA, generation of electricity and the use of thebiogas in heavy vehicles.From an environmental perspective production of biogas is a better way totreat OFMSW than incineration. When biogas is used for electricitygeneration …
