The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

Together with NCC and Sweco we measured the air-flow on a semi-detached house in Jönköping. When a pressure measurement is made, the house gets exposed to over- and under pressure. This is done in order to examine the houses climate shell. The climate shell of the semi-detached house we tested exceeded the required air thickness in BBR-2002, hence, measures have to be taken.This report also displays the importance of building air thick houses and what consequences a non air-thick house can have for the ones residing the house. A discussion of different measures is on for the addressed problems with the flow-measurement and the alternative construction-solutions.Furthermore we have described in this report of how to account for the performance of the air pressure, what kind of equipment we used and how we came up with the results.

Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.

The world is in a stage of climate crisis where the average temperature is rising, with consequences such as, melting ice sheets, increasing sea levels, and floods. The climate panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis.The increasing emissions of carbon dioxide are connected to human consumption patterns. This puts pressure on the earth, as humans demand more and more resources. Today the earth needs one and a half year to regenerate the resources humans? demand of it, by the year 2030 we will need two planets in order to cope with this increasing demand of resources.At a global level it is established that richer countries have a stronger consumption pattern than poorer, and thus generate higher levels of carbon dioxide emissions.

Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.

This paper examines what affects the demand for five Swedish ethical funds between the years 1997-2007. The purpose of this study is to examine if there is a relation between fund value and other values than just financial. This study examines if the number of conflicts in the world and the media?s coverage of the climate change debate could have an impact on the demand for ethical fund. A multiple linear regression shows that we don?t have a significant result from the examined variables except for household wealth.

AbstractTitle: A changing climate? A study on the changes of the communicativeclimate. Klimat i förändring? En studie om det kommunikativaklimatets förändring.Author: Anne BjörckAim: The aim of this essay is to study changes in the area of the communicative climate and link that to Karl Weicks thoughts on communication and change. Karl Weick is famous for his contribution to organizational theories and he is still very well used around the world and that is the main reason to why his theory is served as a base in this essay.Method: The essay has a theoretical base with elements of qualitative explorative research method.

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

This thesis examines the ways in which adaptation and vulnerability are framed in national and sectorial policy-documents dealing with expected societal impacts of climate change. By using theories of discourse and ideology, the analysis aims to find and understand important ideas and presuppositions that are explicitly or implicitly expressed in these documents in order to make possible and tangible the institutional production of policy within the potentially far-reaching problematique of climate change adaptation and vulnerability. The analysis shows that there are two main perspectives through which vulnerability and adaptation are framed; one focusing limits to societal robustness; and one contesting the institutional capacity to implement adaptations. The author understands these framings as complementarily optimizing preconceived social and economic relations, something that might, in fact, reduce the response capacity of people..

South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.

This study was carried out at a company within the computer industry, a sector that is expanding and is facing scarcity of competent personnel. The purpose was to examine factors that are crucial for being an employer of choice. To get a profound picture of the employees' comprehension of their work situation, a qualitative method with semi-structured interviews with ten of the employees were conducted. To examine factors that are important for future employees a survey was created and handed out to fiftysix civil engineering students majoring in computer science. The results from the interviews showed that the organisation's culture was of great value to the employees.

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

 Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.

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.

AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.
