The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

Byggsektorn står för en stor del av de emissioner som påverkar klimatet negativt. Byggmaterial baserade på trä påverkar den globala miljön mindre negativt jämfört med alternativa byggmaterial som betong. Trähusindustrin kan därför anses ta ett miljömässigt ansvar eftersom deras produkter har en lägre klimatpåverkan, vilket bidrar till att minska byggsektorns totala miljöpåverkan. Informationen om träbyggandets klimatfördelar behöver också kommuniceras för att skapa möjligheter för kunden att göra miljömedvetna val vid köp av hus. Idag tenderar trähusindustrin att marknadsföra kostnadseffektiva fördelar i större utsträckning än miljömässiga sådana.

A lot of houses built during the Million Homes Programme are in need of major renovation. Today?s technology and materials are better than in the 60?s and 70?s. Both Swedish government and the European Union have set climate goals regarding energy consumption by 2020 and 2050. Achieving these goals would require better standards in buildings than the Building regulations demands, such as Umeå municipality?s construction requirements for new buildings.The report aims to investigate if a renovation of apartment buildings from the Million Homes Programme can reach Umeå municipality?s construction requirements.

Coastal areas are popular for housing, both for permanent living and holiday houses. At the same time, thin sediments and small storage capacity in the bedrock makes the ground water resources limited. The limited ground water resources combined with too large withdrawals of ground water makes salt water intrusion a problem in many coastal areas. This study examine the risk of salt water intrusion in drinking water supplying wells on the island Södra Finnö in S:t Anna archipelago, Östergötland, Sweden. A calculation of the relation between ground water recharge and withdrawal is obtained to analyze the ground water balance in the area.

The concept of domestic violence pertains to different definitions of violence, one of which is the concept of honour related violence and oppression. This paper looks at honour related violence and oppression, as defined in policy documents at a central political level, and how various discourses stand in relation to social categories and power relations. Consequently, the theoretical and methodological premise of the paper has been based on discourse analysis and an intersectional perspective has been applied to gain further depth and breadth in the analysis of the material. The intersectional perspective houses various approaches to the understanding of specific phenomena based on factors of gender, ethnicity, sexuality and class. The analysis concludes that the concept of honour related violence and oppression is a concept without a single scientific definition. There is, however, a general consensus in the political context that honour related violence and oppression is a collective force that can be directed at both sexes.

Abstrakt -  As energy prices rise, energy-saving in buildings is becoming increasingly important. By applying different construction and installation technologies, to new buildings the energy consumption can be reduced effectively, compared to similar existing buildings. These technical measures are often an investment in the long term and will reduce energy costs significantly. The purpose of this report is to show how to reduce energy consumption in a small house. It is presented in this report that both building's technical saving arrangements (the sealing of a building) and an installation technical arrangement (changing from the F-system to the FTX-system) would reduce energy consumption in newly built detached houses, if compared with a similar existing house but without these technical measures. The report presents also detailed calculations showing how much energy an existing 2-storey house, built in the year 2007 in Eskilstuna, consumes and how much energy would be saved if these corrective measures were applied to a new building. It is also reported how much money would be saved each year over a 10 year period if the measures were applied. The results show that both solutions are a good investment in the reduction of energy consumption and hence the cost involved. Keywords: energy, heat energy, infiltration, FTX-system, free temperature effectively. .

Negativ miljöpåverkan i form av föroreningar och koldioxidutsläpp är enorm idag. Men också de stora kostnader som tillkommer när man ska försöka bygga miljösmart. Framtiden kräver av oss att börja utnyttja förnyelsebara råvaror för en hållbar utveckling. Trä anses vara ett miljövänligt material och bör användas som stommaterial i höga byggnader i större utsträckning än det görs idag. De vanligaste stomsystem som förekommer i träbyggnader är pelar-balksystem, skivsystem av massivträ och regelsystem. Dessa tre stomsystem kan sedan kombineras i tre olika byggmetoder: platsbygge, prefabricerade planelement eller prefabricerade volymer.Det finns flera aspekter som påverkar valet av stomsystem och byggmetod, t.ex.

This master thesis is based on the sociocultural perspective. A qualitative research study was conducted to investigate children's attitudes towards reading, texts and libraries.The theoretical background is constituted by ideas from the new sociology of childhood, literacy-studies and reader-response theory.The study was conducted with 23 children, 13 girls and 10 boys, participating in focus groups.The results of the study reveal that children's literacy-activities in school are strongly influenced and limited by adults. Children's interest in pictures and non-fiction-reading do not correspond to the school institution that favors traditional media and fiction. The study also reveals a gender division between children's literacy-activities that tends to grow with age. All the children in the study regard libraries as book-houses and wished for libraries that combine activity and serenity.The thesis shows the importance of being aware of, and engage in, children's reading-interests and reading-practices if the reading stimulating activities in schools and libraries are to be successful.

During the years of development in the 60s and 70s the need for new housing in Sweden arose. Sweden was going to be the most modern country in the world. This period has later been called ?the time of the big programmes?. One of the parts in this building of a welfare society was a large policy of building politics with few counterparts in history.

Många byggnader är idag fuktskadade. Fuktskador uppstår på så väl nya som gamla byggnader. Idag provtrycker man hus för att få ett värde på dess täthet, men många hus som klarar täthetskraven drabbas ändå av fuktskador. Detta beror på att otätheterna är lokala på en eller flera delar av klimatskalet bortsett från otätheter vid anslutningar.  En studie har gjorts på två väggtyper; en standardvägg och en passivhusvägg.

Syftet för den här undersökningen är att försöka se och belysa vad som utmärker verksamheten i en barngrupp på en mångkulturell förskola. Detta syfte har delats in i tre frågeställningar-     Vad har pedagogerna för pedagogiska tankar kring sin verksamhet?-     Hur arbetar pedagogerna med språk?-     Hur ser samarbetet mellan förskola och hem ut?Undersökningsmetoden för arbetet har varit kvalitativa intervjuer med fem pedagoger som arbetar med mångkulturella barngrupper.Resultaten jag har fått fram kring vad som utmärker sig under de olika frågeställningsrubrikerna visar att pedagogerna menar att de;-     arbetar mer konkret än i icke mångkulturella förskolor, och att de försöker vara mer närvarande i barnens lek, för att hjälpa barnen med sin tvåspråkighet;-     upplever att personal med annat modersmål än svenska är en stor tillgång i verksamheten, likväl som resursen modersmålspedagog, som finns i de rektorsområden jag gjort min undersökning i. De uppger även att de uppmuntrar barnen att använda olika språk i förskolan;-     tycker att samarbetet mellan förskolan och föräldrarna fungerar bra, och att föräldrarna är delaktiga i verksamheten. De poängterar även att kontakten med föräldrarna är viktig, och att man måste vara tydlig, då det kan vara språkförbistringar..

Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.

The private sewage systems in Sweden releases around 600 tons of phosphorus per year, compared to about 350 tons from municipal sewage treatment plants, and they account for approximately 21% of the total anthropogenic discharge of phosphorus into Swedish waters. About 40% of Sweden's nearly 1 million private sewage systems are inferior with respect to emissions to surface and groundwater. The technology of small sewage plants is under development and knowledge of treatment effects for different solutions is poorly consolidated. Municipal authorities lack resources to keep up with the technologic development and assess the reliability of the treatment performances that suppliers report for their products. The thesis aims to conduct a market review and evaluation of wholly or partially prefabricated small sewage plants, to make it easier for municipalities and property owners to assess different technical solutions. The goal is a compilation of the products on the market, evaluated on the basis of the reliability of specified degrees of reduction.Information on sampling procedures and test results were collected through a questionnaire to all active suppliers and the responses were then used to classify the products.
