… roof area which is available according to the solar irradiance map. In a life cycle perspective, photovoltaics purchased on the global market are expected to cause greenhouse gas emissions of 45 g CO2-eq/kWh.
… of the winding robots. This could reduce about 20 % of the total winding cycle. If this preparation were to be carried out manually it would take about five hours and ten minutes for each stator.
En balans mellan hållbar utveckling, klassisk design och unikitet kan bidra till att minska dagens konsumtion. Begreppet ekodesign innefattar en produkts miljöpåverkan genom dess livscykel utan att äventyra med andra komponenter som kvalité, kostnad och formgivning. Att skapa en …
Där värme- och elproduktion samt lönsamhet studeras och avfall är huvudbränslet
… and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the …
This thesis concerns how Sweden relates to life cycle assessment (LCA) in the construction process. LCA means analyzing a products impact and the analysis includes the whole life span of the product. A building has a high complexity and the combination with its unique shape will …
… was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction …

… analysis is done by calculating the total cost over 20 years with an LCC (Life Cycle Cost) in present value. This calculation is done by using three possible scenarios, where the discount rate, inflation and price rise of energy are varied from a normal case, which is considered …
… of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production. The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the …
… the dependence between fiscal policy on municipality level and business cycles has only recently sparked a debate among Swedish economists. Studies point out that a law which came to force in 2000, balanskravet, may have caused municipalities to lower expenditures, alternatively …
