Energiberäkningar för passivhus
AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.
Kan implementering av Lean leda till effektiviseringar i skandinavisk sjukvård?
AbstractOur purpose for making this study is to study the implementation, the use of and the effects of Lean within our case objects. We chose to make this thesis by case studies. The three themes mentioned above is also the main research questions that we aim to find an answer to by this study. We have chosen to do a cross section analysis where we conducted structured interviews to find answers to these questions. The theoretical reference frame consists partly of traditional theoreticians within Lean but also more recent research within the subject as well as theory specifically for Lean within the Health Care sector.The result of this study shows in all our case studies that the Management has been supporting the implementation, but that the implementation process proceeds faster if also the professionals are involved in the process. To succeed with the implementation there is a great need for good reasons and strives that can benefit the professionals. By the use of Lean our case studies have evaluated its processes, with the main intentions being to reduce waste activities and to create flows with ?pull systems?.
Konstruktionen av företagare som diskursiva subjekt : en diskursanalytisk studie av hur kvinnor och män representeras som företagare i tidningen Eget Företag
Given the possibility that the world, as we know it, is a consequence of human interaction and verbal communication our understanding of the world can be seen as contingent rather than essentially given. Conceptions such as "entrepreneur", "woman" and "man" can then be understood as socially constructed subjects. Departing from poststructural and social constructionist perspectives I will examine medial representation of women and men as entrepreneurs. My main purpose is to examine how the entrepreneur is constructed as a discursive subject in the journal Eget Företag. Drawing upon Ernesto Laclau´s and Chantal Mouffe´s Discourse Theory and the poststructuralist feminist theoretical perspective of Judith Butler I will discuss both the construction of the entrepreneur as well as the more explicit question; is gender significant for the construction of the entrepreneur and entrepreneurship in Eget Företag? In this study I come to the conclusion that the discourse of entrepreneurship, as well as the journalistic discourse, draws upon discourses of femininity and masculinity but also upon discourses of ethnicity.
En kvalitativ studie om hur chefer i socialt arbete ser på sitt ledarskap
The aim of this study was; from a group of boys and girls description and interpretation of interaction with other young people, personnel and the environment of the youth centre illuminate how the social gender are constructed and maintained at the youth centre. In this study we have tried to analyse the phenomena from an intersectionalistic perspective. Except gender, the analytic category social class have been tried to capture. Our theoretical standing point is social constructivism. Institutionalized structures in our society are constructed by humans, gender is not only a biological construction it is also a man created construction.
Problemrepresentationen av arbetslöshet och arbetslösa : En diskursanalys om problematiseringen av arbetslöshet och arbetslösa i nationella policydokument åren 1979/80 och 2006/07
This essay is about the problematization of uneployment and unemployed in national policy documents of the years 1979 and 2007. The purpose of this essay is to illustrate and analyze the problematization of unemployment as a construction. My overall aim is investigating how the unemployed and unemployment are represented and constructed in the Swedish political debate the years of 1979/80 and 2006/07 by analyzing national policy document. The analysis will consist of questions about the problemrepresentaion made by unemployment and the unemployed, the assumptions behind this problematization and what kind of impact it could generate for the unemployed. In this way, the study aims to investigate the changes that may have occurred in how unemployment is problematized in the Swedish policy documents and highlight citizenship conditions on the basis of labor market policy.
Lean Construction i teori och praktik
Höga byggkostnader, kvalitetsproblem, dyra kostnader för omprojektering och
låg lönsamhet för entreprenörer är exempel på problem inom byggbranschen.
Statistik pekar på att byggkostnaderna för att producera byggnader har
stigit kraftigt under de senaste åren. Byggnadsentreprenörer har börjat
utveckla alternativa metoder för att genomföra kostnadseffektiva projekt.
Denna studie kan delas upp i två delar, en teoretisk och en empirisk del.
Den teoretiska delen utgörs av litteraturstudier för att få djupare kunskap
och förståelse om Lean konceptet. Den andra delen avser en empirisk studie.
Grönskande balkongkonstruktioner : Jämförande arkivstudie av balkongkonstruktioner anpassade för urban odling
Urban agriculture is a current topic and this study examines the possibility of cultivating on balconies in the city. The study was performed at Uppsala University and examines, from a structural engineering perspective, how different existing balcony/terrace structures are affected by cultivation. A cultivation balcony defined in the study as a balcony/terrace which is specifically designed for cultivation. Three units of study have been selected according to this criterion. Four factors were examined, these were loads, moisture/water, economy and cultivation.
Uppvärmningssystem - En analys av valmöjligheter för småhus
When constructing a new house many questions appear, from architecture to decisions regarding installations. Sweden is situated in a cold part of the planet and questions regarding which heating system to install face everyone who decides to build a new house. This thesis describes a construction solution of a villa in Kiruna. The extended essay analyzes which heating system is most suitable for the construction. The options are geothermal, district and pellet heating systems.

Förutsättningar och hinder för att använda offentlig upphandling som styrmedel för en hållbar hantering av entreprenadberg
Large volumes of excavated soil and rock are generated in building- and construction projects. These materials need to be transported longer and longer distances due to the densifications of cities. The transportation affects the environment in terms of noise and emissions, but also makes high demands on road infrastructure. To reduce the transport distances an increased responsibility for the excavated rock generated needs to be taken. Responsibility can be increased through an introduction of means of control.
Bergvärme och solenergi i flerbostadshus : En förstudie över Kv. Uppfarten
The society strives for sustainable development, in the construction industry it is expressed through sustainable building. Energy and LCC analyzes increases the ability to make conscious decisions in the process. A problem in the construction industry is that energy and LCC analysis is not used to the desired extent, as they are perceived as complicated and time consuming. The report aims to achieve a more sustainable building through increased use of energy and LCC analyzes.The goal is to show how BIM can be used to improve the efficiency of the energy and LCC analyzes.The study was conducted with a literature review and a case study to answer which information that is required in a BIM model to perform energy and LCC analyzes. The study also shows which software can be used in BIM based energy and LCC analyzes and how the analyzes can be carried out efficiently.The result shows that effective analyzes may be performed if the BIM-model contains the relevant information for making analyzes.
Samhällsekonomisk analys av ett djupförvar för använt kärnbränsle i Forsmark :
This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark.
Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it.
The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.
IMPLEMENTERING AV ARBETSMILJÖLAGENS ÄNDRINGAR, GÄLLANDE FRÅN 090101, PÅ BYGGARBETSPLATSER
In the EU there are EC Directives that Member States of EU should follow. Sweden has undertaken to transpose EC Directives regarding the working environment to Swedish Provisions. In 4 April 2006, the European Commission had some criticism against the Swedish implementation of the Construction Sites Directive. The Swedish Work Environment Authority has in response to this criticism reworked the Work Environment Act and related provision about building and civil engineering work. The changes came into force 1 January 2009.These changes have resulted in some working methods and even new responsibility subjects must be reviewed. The purpose of this exam project was to investigate if contractors and clients in the construction sector, had have time to update themselves on this front and adapt to these changes.
Konstruktionen av en "invandrare" - I mötet mellan tillskrivandet och behovet av en kollektiv identitet
The way society categorize different people into groups is problematic in the sense that the categorization can seem stigmatizing and have social consequences for those being categorized. Immigrants are one of those problematic categories.The following essay studies this categorization of ?immigrants? based on a governmental investigation of structural discrimination that took place in 2002-2008. The aim is to study the use of the category ?immigrant? and the consequences that follows such a categorization.
Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet
Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.
