En ekonomisk jämförelse vid upprustning av miljonprogrammetsflerbostadshus
As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor …
En jämförelse mellan ett passivhus och ett konventionellt hus
As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor …
The aim of this study is to find a method to incorporate the energy demand of a building in the investment cost estimate. The study is based on an actual apartment block. The significant energy aspects are identified, and changed to more energy efficient options. These are then …
en lönsam investering för ett lantbruk?
… slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The …
… was to compare productivity in first thinning of birch stands, when either energy- or pulpwood was harvested. The systems total profitability was also compared by including forwarding and chipping costs. A Gremo 950 HPVR harvester was used and the same driver was used under the …
… with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the …
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a …
… nitrogen utilization and profitability. Feed efficiency is defined as kg energy corrected milk per kg dry matter intake in the present study, while nitrogen efficiency represents the nitrogen used for salable product in relation to total nitrogen intake. Separate feeding is …
a study on production conditions and international competitiveness
… led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production. The Baltic States have emerged as one of the largest wood pellet …
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 …
… dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high …
a sunny story?
In Sweden there is a large interest in renewable energy but the market for solar power is still small compared to other countries such as Germany. Here many farmers produce their own electricity. The Federation of Swedish farmers have acknowledged the potential for Swedish …

… no only growth as in heifers but also to produce a calf. The heifers must have energy for both the fetus and the milk, if the calf is with the mother during the summer before slaughter. Heifers are good in extensive production because they obsess fat at a low weight and are easy …
… global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the …
