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.

This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.

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.

Not enough attention has been paid to the correlation between the failure of peacekeeping operations and the actual source of civil wars. This text is an attempt to fill that gap. Hence the question: under which conditions is it possible for peacekeeping operations to replace the responsibility of the state concerning the security aspects of the social contract? The outset of the text, using the theories of Robert Nozick, is a theoretical approach towards the founding of states, described as the merging of entities. The theory serves a purpose since it, in combination with identity, illustrates in what manner the glue of society occurs and the rallying around other kind of loyalties like clans and ethnicities.

The UN was established after the Second World War. The organization?s primary goal was to maintain peace among all nations. When the UN intervenes in other states affairs, it is violat-ing the principles it is set to defend, principles of non-intervention and respect for sover-eignty. The outcome from such interventions is very important, a result that can legitimize the action.

This diploma work was performed because the company Sveriges BostadsrättsCentrum, with the abbreviation SBC, had a need to gain insight into how changes in the Work Environment Act and related regulations which took effect January 1, 2009 affecting their work with the work environment. The changes mean that the client may hand over his work environment responsibilities to a contractor and that he has to select so-called building work environment co-ordinators. At SBC they are working as representatives for tenant-owner's association when a construction is about to be carried out. The purpose was to ascertain how changes may affect the work at SBC. The diploma work intends to educate the staff at SBC how work with the work environment would look like if they met the regulatory requirements.

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

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.

By using industrialized building, pre-installed modules can be delivered to the construction site where they are easily mounted. This method has many advantages compared to on-site manufacturing, for example, the precision during the production process should be much higher than building each wall and floor on site. Furthermore, the quick erection procedure when using prefabricated elements and the possibility to use weather protection has the advantage of not being dependent on weather conditions, and many other factors.Masonite Beams AB is a Swedish company (a member of the Norwegian company, Byggma ASA) with a relatively new technology using light weight beams as bearing elements in the walls and a certain stiff board lamella slap which is mounted on the top of the floor structure creating an integrated stiff beam / board floor structure. The elements are flat which make it much easier to transport the elements from the factory to the building site where the building parts are easily mounted with special mounting stud.One of the main drawbacks of lightweight structure is the sound transmission. The main topic is low frequency annoyance, however the complex structural elements and their mutual sensitive connections other acoustical problems might appear.

Syftet med det här examensarbetet är att undersöka om det är möjligt att överföra hallbyggnadsteknik till produktion av småhus för att sänka produktionskostnaderna. Studien visar att hallbyggnadsteknik enkelt går att överföra till en villa. Dessutom blir det billigare att bygga klimatskalet med vårt byggsystem jämfört med ett traditionellt prefabricerat småhus. Genom detta system kan den totala byggkostnaden för villan i jämförelsen sänkas med 3-10 % beroende på vilket fasadmaterial som väljs..

There are many factors in a building project that has to collaborate with one another in order to reach the desired end result, how you work with moisture issues in timber is a very important one. While constructing Varbergs Hospital, the building company Skanska came in contact with the issue of extra high demands on the moisture content in timber. What they requested from us was a moisture program in which you clearly could follow the routines regarding work with moisture in timber. The aim is to use this program as a help during the work, in order to achieve a good result.We have developed this study in addition to the moisture program. The aim is that this study will give you a deeper understanding of the important factors to consider.

AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses. This property currently has a high energy con-sumption and therfore it is desirable to improve the efficiency. In ordet to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss.
