All around the world more and more people move from rural areas to live in the cities. Because of this, the urban areas have become an important part in the debate about the effects on the environment and sustainability. In many countries word wide initiatives have been taken to build sustainable cities and eco cities, the Stockholm Royal Seaport is one example. The vision for the district is to become a world class sustainable city based on the three dimensions of sustainable development: social, economic and ecologic. The municipality of Stockholm has set requirements for the buildings? energy usage, emissions and amount of waste generated during the building process.

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.

Poorly maintained forges are a common sight in the province of Gästrikland. Because of their changed appearance, possible move from the origin location and poor items related knowledge they will rarely qualify for the range of funds available through Länsstyrelsen. Therefore this study deals with the problems associated with the forges in southern Gästrikland, i.e. Hedesunda and Österfärnebo parishes.The aim of the study is to increase the items related knowledge of forges and perhaps form the basis for restoration projects in the area. Eleven forges have been examined and the changes they have undergone have been highlighted.A forge was erected on the farm and was used for the households needs such as producing and repairing tools.

This thesis tries to clarify why more houses such as passive houses is not built and at the same time the differences is described with the conventional construction as a starting point. Sweden has set environmental objectives to reduce energy consumption in buildings by 50 percent by the year 2050 compared to 1995. The passivehouse concept could have a significant role, particularly in the reconstruction of buildings with high energy consumption. For sustainable building the passivehouse technology is an economically viable concept while benefiting the environment. Initially an introduction is given of the background to the problem, purpose and objective of the thesis.

The purpose of this paper is to analyse and discuss clinch-nails found at an excavation at terrace II in the Garrison of Birka, on the island of Björkö in Sweden. This type of clinch-nails is common in Viking age Sweden and is usually interpreted as coming from boats. The study will try to show that these types of nails could have been used in several kinds of wooden constructions. It will also show how the nails were made and what kinds of tools were used by the Viking smiths. The study has shown that this type of nails were used in several different types of wooden constructions such as boats, sleds, cart bodies, coffins, Birka's ramparts and buildings.

Construction companies in Sweden have for recent years seen an increase in the numbers ofwarranty complaints associated with the market of resident buildings and the cost for this hasbeen measured to over 1.2 billion SEK per year. Working with poor quality cost as a way ofcreating insight about defects within the company?s processes is a method developed and usedby the manufacturing industry for decades, but have not yet reached the construction industry.This study has been performed in collaboration with a Swedish construction company, wherethe author has been stationed at the aftersales division for residential buildings. Owing tocircumstances, this published report has been made anonymous regarding the company whowill further on be namedthe Company. The Company is aware that warranty claims producegreat costs and has requested a way of putting cost and cause to specific claims in order ofreceiving a more specific cost view and to make the reuse of knowledge more efficient.

The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.

The author has, with the help of AK Consultancy Indoor Air AB, formed a series of questions regarding moisture problems in buildings and how these are handled in extreme climates with high temperatures and a high relative humidity. Furthermore to analyse and indentify key material that makes a construction safe against moisture problems. Ventilation, AC and the choice of materials have in a later stage of the thesis been investigated to enhance the knowledge of moisture protection. The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.

Energy and environmental demands regarding buildings have become an increasinglydiscussed topic, both in Sweden and in Europe as a whole. The general trend indicatesthat greater efforts are being put into the energy efficiency of the built environment.There are already numerous examples of houses with a low energy demand, and thenumber of low energy buildings is constantly growing.At the time being, the maximum level for energy demands for housing in Stockholm is110 kWh/m2year, but as soon as next year the limit will be changed to 90. The Swedishagency Energimyndigheten is currently conducting a project to interpret the EU Directiveon the so-called Nearly zero energy buildings, and the preliminary results indicate thatthe level of requirements for purchased energy will end up with about 55 kWh / m2year,which is in line withtoday?s recommendationsfound in FEBY's Kravspecifikation förPassivhus.Starting with a low-energy house in Henriksdalshamnen in Stockholm, we have analyzedvarious energy-efficiency measures and their influence on power and energy needs. Thefinancial aspects associated with the measures have been studied using a model of lifecycle costs.The measures were initially studied individually to give an idea of how much impact theyeach had.

In June 2006 the Swedish government decided that the use of energy in buildings should be reduced by 20 percent until 2020, compared to the level of energy used in 1995. To contribute to this goal, the real estate company ?Eskilstuna Kommunfastigheter AB?, set up own goals for their buildings. In 2009, the goal for schools was to have a maximum energy use of 118 kWh/m2year for heating and hot water.The school ?Hållsta skola?, just south of Eskilstuna, exceeds the limit since it used 270 kWh in 2008.

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.

Kulturvårdscentrum was a project that had great significance for local folklore societies in Bohuslän.Bohusläns museum was i charge of the project that lasted from 1987 until about 2001 when most ofthe original staff have retired. The staff was mainly recruited from a large shipyard, Uddevallavarvet,at it's closure due to recession. Financing was largely made by the government to help outthose unemployed who otherwise should have a hard time finding a new job. At start there was about25 employees who where trained for one year by staff from Swedish museums, conservation studios,and teachers the university. The education was aimed at serving local folklore societies, and dealingwith their special problems.

Climate change is an increasingly widely known concept. In the EU the construction sector is responsible for more than a third of the carbon dioxide emissions and 40 % of the total energy use. In Sweden, measures have been taken to prevent this climate change. By 16 targets, three of which can be linked to the construction sector, Sweden will reduce the negative trend. None of the three goals with relation to the construction sector will however be achieved before 2020.
