Energieffektivisering av arbetsbodar på byggarbetsplatser

Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.

Skriftliga omdömen : Om åttaåringars förmåga och möjlighet att förstå sina omdömen

Syftet med studien är att öka kunskapen om elevers förståelse av sina skriftliga omdömen och om vilka faktorer som påverkar förståelsen av dokumenten. Forskningsansatsen är starkt inspirerad av grundad teori. Studiens resultat utgår dels från analys av intervjuer av elever i år två och dels från dokumentanalys av elevernas skriftliga omdömen. Dessa båda har i den avslutande analysen relaterats till varandra, vilket har resulterat i en teoretisk modell, EFO-modellen som står för Elevers Förståelse av sina Skriftliga omdömen. Vid intervjuerna framkom att eleverna förstår omdömena på olika sätt och i olika utsträckning. Förståelsen påverkas av elevens motivation och koncentration, deras behov av bekräftelse samt deras språkliga förmåga.

Fjärrvärme - ny lokalisering av kraftvärme i Enköping

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Att låta tusen blommor blomma. - Lärares syn på relationens betydelse för elever med koncentrationssvårigheter.

The aim of this bachelor's thesis is to investigate how teachers view the way they build their relationships towards students, both in general and, more specifically, towards those students with some type of attention deficits. The focus of this thesis has been on how great an importance teachers place on this relationship. Especially when it comes to working with students with attention deficits. We also want to know to which extent this relational perspective is rooted in teachers' practice. The theoretical basis of this study is the relational perspective formulated by Aspelin and Persson (2011).

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

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.

Nu är det dags! En kvalitativ studie om när socialsekreterare institutionsplacerar ungdomar

The purpose of this study was to examine social workers apprehensions about institutional placement of youths and what determines when these proceedings are used. When research not always shows that institutional placements lead to positive changes for youngsters, we wondered how social workers act on their assessment to institutional placement. We wanted to find out if the social workers meet any dilemmas along the way. To find out about that we used qualitative interviews with ten social workers, who worked in social service and came from different places in the southern parts of Sweden. To analyze our material we used the theory of human service organization and street-level bureaucrats work situation.

Beräkning av massbalanser för metaller i vatten samt miljöriskbedömning av Nerån vid Österbyverken i Östhammars kommun

Österbyverken is an industrial estate in Östhammars municipality in Uppland, Sweden. Many different activities have taken place on the estate the last 600 years. During the last 15 years both health and environmental studies have been made by different companies. At the most recent study a great increase of metals in Nerån, a river that runs partly through and partly next to the estate, was identified with mass balances. The purpose of this thesis is to accomplish a deepened study about the reasons for the increase of metals in Nerån.

"Det är så lätt, det är bara att gå in och trycka på ett par knappar." En rättssociologisk utvärderingsstudie av lagen om upphovsrätt (Lag 2005:359) och de viktigaste orsaksmekanismerna bakom fildelning

The purpose of this study was to find out why the law that regulates downloading copyrighted material does not work and which of the most important main reasons lies behind downloading behaviour. The phenomenon being well investigated earlier has actualized a new demand for normative investigation in connection with the hot debated IPRED-law.Using qualitative method comprising of interviews with three typical file sharers and anchored in Max Webers action typology, rational choice theory and the norm model followed by two assessment models, we found that four important reasons lies behind downloading behaviour: 1) economical reasons was the most central and frequent determinant followed by 2) accessibility and comfort, and 3) social acceptance and moral and also 4) habits. Although the content of the law was correctly provided by the interviewees, it was clear that they did not perceive the impact of the law as meaningful or threatening.The results, being compatible with previous research, are discussed in terms of the named theories and assessment models. We suggest further research to take into account peoples norms as the new IPRED-law soon will be functional as well as studies from a perspective of the legal rights of the individual..

"Man nöjer sig med att prata med föräldrarna" : En kvalitativ studie om socialtjänstens bedömningsprocess efter inkommen 14 kap. 1 § SoL anmälan.

The aim of this study was to reach a deeper understanding of the process that occurs within the social services after receiving a notification according to Chapter 14, section 1, The Social Services Act. More specifically the focus of this study was to illustrate how social secretaries reason about children?s participation in the process, as well as to examine whether the legislative change, Chapter 11, section 1 a, The Social Services Act, has affected the process in any way.

Organic material used for biogas production can also undergo other treatments. The emissions and impact from the different treatments are evaluated in this environmental assessment, with a focus on energy and climate. The materials included in the study are organic household waste, slaughterhouse waste and liquid manure. Other than biogas production, the possible treatments for organic household waste and slaughterhouse waste are incineration and composting, and for liquid manure storing and spreading. The analysis is based on data and information from current and relevant literature, and relates to the conditions in the Swedish energy system.

En skattemyndighet : Balans mellan maktutövning och relationsbyggande

Background: Power by force and threats used to be the common way to collect taxes, but this procedure is today completely different. It?s now more about building a mutual relationship and with help of laws and controls steer citizens and companies to pay the tax they owe. Thus the way to collect taxes have changed over the years, the collecting of taxes aren?t a popular task to do.

Kirunametoden-Jämförelse emot en konventionell injusteringsmetod

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

Investeringskalkyl baserad på ett flerbostadshus energiprestanda

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

Framtagande av riktlinjer för arbetsplatsbesök enligt nya Plan- och bygglagen

A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.

Kv. Draken : En studie i kostnadseffektivt byggande

Den bostadspolitik som förts de senaste två decennierna har gett oss en alltmer segregerad stadskärna i Stockholm. Byggsubventionernas avveckling på 90-talet har lett till en historiskt låg byggtakt och ett byggande som ensidigt riktat sig till resursstarka grupper i samhället.Parallellt med detta har stora delar av hyresbeståndet ombildats till bostadsrätter vilket medfört att många relativt billiga hyreslägenheter i äldre fastigheter har försvunnit ur beståndet. Dessa är svåra att ersätta med nyproduktion, då dessa är dyrare.Kärnproblemet är förstås att det är dyrt att bygga hus och om man antar att den nuvarande bostadspolitiken består är det ytterst angeläget att utveckla kostnadseffektiva byggmetoder för att möjliggöra lägenheter med överkomliga hyror som kan bidra till att motverka boendesegregationen på sikt.Vårt förslag består av ett bostadshus i Stadshagen. Fastigheten är indelad i två byggnadskroppar som länkas samman via ett system av loftgångar kopplade till ett trapphus. Husen är uppbyggda av volymelement som staplats på en platsgjuten sockel.
