Their main business is new housing and development of residential areas. God quality and low impact on the environment is a part of great importance in the company?s long-term goals.
Förfädernas berg? : en tolkning av fornborgen på Halleberg
The essay deals with the hill-fort on the mountain Halleberg, Sweden, its wall design, functionality, dating and its possible function as a central location and a place of worship of the ancestors.The Halleberg hill-fort consists of a 1500 meters long at times cohesive stonewalls which together blocked the mountain from its surroundings. Hallberg's natural vertical scree and cliffs along with the masonry blocked the whole mountain from the surroundings.The hill-forts, with few exceptions are largely not investigated archaeologically and its functionality and role in the ancient society is based on outdated research on the subject. The current archaeological interpretation is that hill-forts served as temporary defense in times of unrest or served as center of power for a social elite. The prevailing view in the archaeological sphere is that the hill-forts had a variety of functions and that its functionality and role in ancient society has varied.Halleberg´s strongest wall sections are at the mountain's south-eastern part where the natural driveway, Storgårdsklev is located. Along with the massive masonry of the walls in Bokedalen Storgårdsklev functioned as the hill-forts main entrance.
Ytterväggar : En jämförelse och livscykelskostnadsanalys
This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment. However, when wallssimilar insulation properties are beingcompared, the study proves that lowerinvestment cost is more profitable.The report introduces requiredconstruction techniques of walls inorder that the reader should understandwall constructions with different layersand properties. The essay shows theimportance of properly constructed wallsto avoid air leakage and moisturedamage.The essay has been implemented byliterature studies, contacts with NCCand Skanska and by energy calculationsmade by hand and using the software VIPEnergy..
Ombyggnad av lägenheter i ett 1950-tals flerbostadshus till kontorsbyggnad
The report aim to increase awareness of factors that have a major role whenremodelling an apartment building from the 1950s to offices.The thesis can be used for future projects when remodelling apartments to offices.The report can provide ideas and inspirations on how this can be done in aneffective way, ie . A way that does not require rebuilding the supporting structure,but only non bearing walls. The thesis also gives insight on the parts that will needto be supplemented from Boverket?s requirements in terms of accessibility,acoustic and fire requirements.The methods used in this thesis are literature studies, case study and sketch work.In the literature studies, the primary sources were Boverkets byggregler BBR, andArbetsmiljöverkets föreskrift AFS 2009:2 but other literature were also used. Theprimary items were chosen from the literature studies and they were furtheranalysed in the sketch work.
Prefabricerade passivhusväggar
Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.
"Prata högre! Jag hör inte vad du säger" : En kvalitativ studie om elevers och pedagogers upplevelser av Södertäljes nya skolmodell
"Speak up! I can?t hear you"This qualitative study is built on an investigation of a newly instated model that is used when building or renovating schools. The principles of the model are based on building schools with an open plan design where the walls are made of glass and the classrooms are not shut closed by walls, instead the classrooms are completely open except from screens that are used to indicate the ambit of the rooms. This model has been well debated and that is the reason why we chose to do this study.The purpose of this study is to find out how students and teachers experience this model. To do this we have done interviews and observations.
Stenmuren i landskapet : bevarandet av ett kulturarv
The landscape with its associated historical tracks and remains are an important part of our cultural heritage that we consider important to conserve. The stone walls are an example of historical remains that helps to build up this cultural heritage. It is a landscape element that today usually is being associated with the old cultivated landscape, where they mainly functioned as boundary markings and fences. Today, the stone wall is a valuable element in the landscape with ecological, culture-historical and aesthetic values. Since the stone walls arose as elements in the landscape a lot has been changed within the agriculture.
Norrberga Skolmodell- En ny modell av skola : Vad några elever i sjätte klass tycker om sin skola
This study titled School Model of Norrberga- a New Model of School. Some opinions that six pupils in the sixth grade have of their school is an explorative study. The purpose of this study is to some extent explain the ideas behind this quite spectacular model of school and the intentions of the City Council of Norrberga as they decided that all the schools that were to be renovated or built in the town of Norrberga had to follow a specific script. As I first visited The Moonlight School I was puzzled. How do the teachers work it out? But, above all: Do the pupils work it out? What do they think about their school? When I was to write my final essay I wanted to try to sort this school out in more scientific terms. There is a nice, warm atmosphere at the school and the pupils make good results.
Intelligent remuneration in the knowledge economy
Talented people are recognised as being the most important corporate resource over the next twenty years and a competitive compensation system is an important tool in attracting and retaining talent. Traditional pay systems are recognised as being neither cost effective nor motivating people to do more. Often these systems do not contribute to strategic objectives. This study outlines what constitutes an intelligent remuneration system that will enhance the mind value added by knowledge workers, reward knowledge creation, and contribute to organisational strategies..
Platsgjutet eller Skalväggar?
I och med det enorma användningsområdet av datorsystem i dagens samhälle finns många typer av användare och uppgifter att designa för. Genom designriktlinjer kan utvecklare få referenser och guidning för att skapa användbara applikationer från början. På så vis kan tid sparas i utvecklingsprocessen. Från och med puberteten då människan kan anses vara vuxen ändras förmåga till andraspråksinlärning, trots detta finns det människor som lär sig andraspråk i vuxen ålder. Kunskap kring vad dessa skillnader beror på måste användas i designen av en andraspråksinlärningsapplikation för att tillgodose människans kognitiva förmågor.

The analysis then forms the basis for the discussion of the similarities and differences observed. These five cairns along with the cairn Uggarderojr are presented in detail and compared. Major similarities were found between four of the five cairns.
Miljövärdering av resurssnål betong med införande i BIM
This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.
Uttorkningsmöjligheter i ett fuktskadat badrum med hjälp av spaltmetoden
Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.
