Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.

Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.

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.

My Finnish grandfather had a passion for architecture, eventhough he wasn?t an architect. In the end of the 1950s he builta wooden summerhouse on a lot outside of a small villagecalled Lempäälä, close to the city of Tampere. Today the lotbelongs to my mother. Every time I visit our summerhouse, itmakes me want to do as my grandfather did ? to build a smallhouse next to it.My project is a proposal for a wooden house on mymothers lot.

Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment friendly, in same time it´s a financial security using less energy, and saving money. The last 10 years in Germany and all around Europe the concept of passive house been developed, and people aim to know more about these concept that leading the market more attractive for passive houses. A passive house is a well designed building highly insulated and air tight with mechanical ventilated system for the whole building envelope that minimizes the use of energy for heating [1].The housing company Mimer has chosen to invest in low energy consumption in every new housing project.  These future plan projects are decided to use less than 75 kwh per square meter annually in purchased energy [2].This thesis is about new constructed passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist.

Kandidatprojektet Urban Building vid Hornsbruksgatan med undertiteln Hornsbruksgatan 2012 är ett arkitekturprojekt bestående av ett mindre antal sammanlänkade byggnationer i vilka bostäder, kontor samt kommersiell verksamhet inryms. Den övergripande volymen består av en tydligt långsmal kropp som är placerad längs med gatan. Stor vikt i projektet har lagts vid den arkitektoniska upplevelsen, materialval och beständighet. Gestaltningsmässigt har inga hinder funnits för eklektiska och anakronistiska influenser..

If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.

This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern Building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.

This study concerns mapping and analysing two different Supply Chains at Setra Group. Setra Group is Sweden?s biggest producer of solid wood and is primarily owned by Sveaskog, Mellanskog and LRF. The Company consist of twelve sawmills, five planning mills and an organisation for distribution of Building material. This study maps one chain for Swedish Glulam standard beam and one chain for solid pine flooring on export to Japan. The glulam chain is based on spruce as raw material and includes all actors between sawmill and the Swedish Building material retailers.

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

This bachelor?s thesis examines the tradition of half-timbered buildings in V?stra G?taland County as there is a current lack of research on this building category in this region. The lack of knowledge may lead to the loss of potential cultural heritage values if these buildings do not receive attention. Therefore, the study aims to provide a more comprehensive understanding of its role within the region. The goal is to expand and nuance the existing research on the Swedish building tradition, particularly in V?stra G?taland County and the general Swedish half-timbered tradition.

This thesis aims to increase understanding and knowledge of issues affecting the redevelopment of older office buildings to housing. The rising demand for housing in recent years has resulted in a need and an increase in cost housing projects. The need has led property owners wanting to build old office buildings to apartments. The case study is carried out in Lycksele town and in close contact with consultancy TM (Technician Mercantile) ? consulting, which has operations in the area.

Lack of political interest and will to deal with human rights violations carried out under the civil- military dictatorship, has characterized the transition and post-transition in Uruguay. The systematic use of torture, arbitrary imprisonments and forced disappearances in the relatively small country created a culture of fear that has been present through out the post-transition phase. Human rights groups have been central actors in the fight for truth and justice and against impunity. This study analyzes how these groups multiple democracy-building functions have contributed to democratic development. It also analyses how the democracy-building functions have been constrained by the political context.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.
