AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor Passive houses, given by FEBY?s1 ?Demand specification for Passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for Passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

This report is the product of the course AF101X, a bachelors degree in Samhällsbyggnad atKTH. The task of the course is to design a small house at a given location and also implement adeepening study. The house in this report is located in Kiruna in the north of Sweden, where theclimate is much colder than in the rest of the country.The deepening study of this report is to evaluates how realistic passive housing north of thePolar Circle is based on those facts. The house will to some extent be designed to fit the passivehousing standard.

This is a work about the relationship between cult houses and halls. In my essay I will go through four different places were cult houses and halls both exist. I will look at the findings and the landscapes were the settlements are located in. The places I have chosen are Lunda in Södermanland, Slöinge in Halland, Uppåkra in western Skåne and Järrestad in southeast Skåne. Because of that the cult houses and halls are occurring during the late Iron Age, it is during this time period that I will work in.

The purpose of this study is to examine how employees in an organization using flexible work practices, experience that passive face time influences the evaluated of them. Further, the study aims to understand to what extent that perception of passive face time motivates the employees to spend more time at the office than is necessary for their work situations. The study concludes that employees in general perceive that passive face time does influence how they are evaluated and that this perception motivates employees that are relatively newly employed by the company to spend more time at office..

During the Nordic Bronze Age, houses were not exclusively connected with profane contexts, but did also feature in burial places, a peculiar fact when considering the careful separation of settlements and graves. What kind of houses do we find in these sacred contexts? What did these houses stand for? Why was the house symbolism chosen to accompany the dead? And why did the house symbolism flourish during the Nordic Bronze Age? To answer these questions three representatives for the house symbolism in Sweden are discussed in more detail, such as the burial in longhouses, peculiar houses called cult houses and house urns. Further, the phenomenon has been put in its temporal, geographic, social and ideological context, where aspects such as trade and settlement structure are presented. The house symbolism is, however, not confined to northern Europe.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on Passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

The problem with passive farmers has arised as an effect of the European Union´s common agricultural policy (CAP) and the decouplement from production-based payments. Payments to passive farmers contradict the purpose of the single payment scheme and constitute a great cost for the EU. The new contractual period after 2013 has given rise to discussions on the direction of the CAP with a purpose of increasing the efficiency of the single payment scheme, and reducing passive farming. The aim of the study is to increase the knowledge about a few factors? influence on passive farmers? attitudes towards land use and the CAP.

The purpose of this thesis is to examine a selection of ideological publishing houses in Sweden today. We want to examine where they are situated in the literary society, their terms and prerequisites. This is achieved through interviews with informants from each of the publishing houses, which we analyze with concepts from the culture sociologist Pierre Bourdieu. The publishing houses are also put in context through information from other actors in the literary field, together with previous research and other material about the Swedish book market. The main research problem in the thesis is to examine the relations between the selected publishing houses ? which profile themselves as ideological ? and the literary field where they exist.

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.
