Rätt fönster i olika väderstreck : En undersökning av energieffektiva fönsters påverkan på byggnaders energiprestanda
The Swedish building stock accounts for nearly 40 percent of the total energyconsumption in the country. Properties built today are likely to last for 100 years orlonger. This places high demands on long-term and smart energy solutions that willkeep the future Swedish building stock energy consumption at low levels. This thesishas focused on examining how the energy performance of buildings is affected bydifferent choices of window types in different cardinal directions. The objective wasto obtain a basis for recommendations on how window properties can be optimizedfor different types of buildings and orientations.
Byggnadsminnesmärkning eller varför är det så ont om Q?
This thesis deals with our heritage and the care of old buildings. In order to limit this vast area a specific attention has been brought upon the process of giving buildings a certain level of protection and after decision having it taken away, instead of giving a stronger protection level.Further limitation has been done through the choice of four buildings in Lund, within Lund University campus. These buildings all lost this certain level of protection. The participants in these kinds of cases have a level of power, what argumentation did they use?The methods being used are discourse analysis, phenomenology and the daily methods of the building care field..
PCB i byggnader : Handlingsplan för saneringsarbetet i Eskilstuna kommun
Polychlorinated biphenyls, PCBs, were used in elastic sealants in buildings during the years1956-1973. Studies of PCB have revealed that it is harmful for humans and animals,especially water-living predators and other top-predators. It is also a persistent organicpollutant and remains in the environment for a very long time. To reduce the levels of PCB inthe environment, it has to be removed from the buildings. According to Swedish law, theproperty holder has to decontaminate sealants with a PCB level of 500 mg/kg or above.
Energibalansberäkning
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. .
HARR (THYMALLUS THYMALLUS) I VÄTTERBÄCKARNA : En studie om samband mellan bottenfauna och harrens förekomst
This thesis aimed to investigate how a rising sea level would affect the livable area of the island Fongafale, Tuvalu. Through the IPCC stabilization scenarios it was examined which areas of the island that would be affected by flooding. The local population?s perceptions of the effects of climate change were studied to see how the consequences of a world-wide problem such as global warming affect people's lives. The paper clarified the Tuvaluans place in the discussion of climate refugees, explained IPCC's work and described the results of previous studies concerning people in Fongafales perceptions and concerns about climate-related changes.
Standardiserad tillverkning av nätstationer
AbstractAbetong in Falkenberg manufactures, among other things, small prefabricated concrete buildings for housing various installations, such as electric transformers.The aim of this dissertation is to reduce the time needed to design such buildings, by way of finding a number of standardized buildings. Standardized in such a manner as to incorporate both the needs of the manufacturer (Abetong) and its customers.To analyze the needs of the parties the work has included a market survey and calculations on the strength of these buildings.One survey was a letter questionnaire to all of Abetong?s customers who have, in the past, ordered these types of building. The aim of the questionnaire was to establish how the customers want these buildings designed.Another survey conducted was an inventory of all of Abetong?s previous projects where these types of building were manufactured.
Gröna tak som del i ett hållbart stadsbyggande
Green roofs have seen a revival in the society of today. They provide many functions
of which both society as a whole and the individual can take part. In particular
extensive green roofs, that requires little or even zero maintenance, provides very
valuable functions. Green roofs affect our environment and our economy in a
positive manner as well as the physical expression of buildings.
In this bachelor thesis the impact of green roofs on society has been examined
throughout literature studies. The result as a compilation of contemporary research
in this field is presented together with a discussion about the use of green roofs in
general.
The two major arguments for an extended use of green roofs are, the high
stormwater retention capacity and the cost-benefits seen over time compared to a
conventional roof.
Trädgårdsstaden : från historisk idé till dagsaktuell verklighet
The aim of this study has been to make clear the conception of ?The Garden City?, and also to investigate why and how the garden city has come to be a more frequent and attractive form of settlement in our Swedish community. The essay is supported by a literature study about the garden city from its beginning (1890?s) to present time. To make a distinct explanation of the garden cities progress over time, I have studied the idea behind two garden cities of today, Tullinge and Vistabergs garden city.
Self-efficacy, arbetsprestation och arbetstillfredsställelse på ett callcenter företag i södra Sverige
This essay looks into the concept of self-efficacy and its implications for work performance. The participants in this study work for a call center company situated in the southern part of Sweden. The hypothesis is that a high degree of self-efficacy exerts a positive effect on work performance. Furthermore, the study seeks to identify the factors that give rise to work satisfaction among the participants. The results of the study show that there is a negative correlation between high self-efficacy and work performance.
Byggnadsminnen och dess försvarbarhet över tid
certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.
Miljöcertifierade byggnader Värde för investeraren
This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.
Kontraster eller anpassning?
Should new buildings blend in or contrast from the older buildings around?
Could contrasts even emphasize different characters? This report is a
discussion on that theme. I´ve studied different architects wiev on the
question and studied different of examples of where new buildings contrast to
the context in a successful way. In part two I´ve done a proposal on a new
housing settlement next to Hammarbyhöjden in Stockholm. The new buildings
contrast to the existing and the aim is to emphasize the characters in
Hammarbyhöjden as well as in the new structure.

New production is not the only thing that is important for the city?s growth. It is also crucial to recover existing buildings in order to create attractive areas. There is a school in Va?stera?s city called Wenstro?mska skolan which consists of six high schools that provide different professional specializations and which has an area of about 35000 square meters.
Hisskärna av skalväggar i höga byggnader : Ett alternativ till den platsgjutna kärnan
A common way to stabilize high rise buildings is to use an elevator core built of concrete. Today, we use to build these elevator cores of in-situ concrete. Precast concrete twin wall (double wall) is a semi-finished product that has become more common in recent years. This diploma work studies how the twin wall works out as structural elements in an elevator core. The work also shows some possible ways of designing twin walls and highlights some important parts of the design that will be vital to the stability of the building. The result shows that it is important to think through where the element joints should be placed.
Munksjökajen : Stadsplanering i Jönköping
Munksjökajen is an old industrial estate on the western shore of Munksjön in Jönköping. The purpose of this thesis is to develop Munksjökajen in accordance with the program for Jönköping?s future development ? Stadsbyggnadsvisionen ? drawn up by the city council.Munksjökajens relations to the surrounding areas have been investigated as well as the need for public transport and possibilities for commercial, municipal and private businesses to operate in the area.The final proposal has a relatively high degree of preserved industrial buildings. New buildings vary in shape and expression in order to create an interesting and diverse environment. The proximity to the lake adds character to the neighbourhood and the water is accentuated by the integration of it in the area..
