Konsumentvänlig Energibesparingsmodell : Ett verktyg som hjälper småhusägare att sänka sina energikostnader

Energy awareness is growing among the Swedish population and a one­?to­?two-family dwelling can save energy. The purpose of this paper is to design a tool that helps these home owners reduce their energy costs.The paper develops a model that gives them an indication of how much energy they can save. For the majority of homeowners, the next step in the quest to reduce theirs is most likely an energy audit. Therefore, information to help home owners to get a good energy audit performed is included in the model.A prototype running the operating system iOS is created and validated against existing models, as well as an energy audit. .

OLJEKRISEN 1973 - En studie i politisk ekonomi kring förlopp och effekter i Sverige och Danmark

ABSTRACTThis thesis focuses on the OPEC oil crisis of 1973 and its impact on the Scandinavian countries of Sweden and Denmark. Starting from Walter Carlsnaes theory of energy vulnerability, the concepts of vulnerability and national security are tested on the selected cases and an array of policy alternatives are assessed. Posited available options like oil stockpiling, conservation, renewable energy and international coordination are evaluated as means for ameliorating the vulnerability of the nations. The theory chosen is further expounded with a consensus element to reinforce its explanatory power. The thesis utilizes a wide range of material from parliamentary records to daily newspapers in an attempt to shed some light on the interplay between economics and politics.Sweden and Denmark evince diverging developments despite their common starting point with exceptionally high oil dependencies and can be located on different ends of the energy policy gamut.

Energieffektivitet och kvalitet på inomhusluft i radon förorenade bostadshus

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

Internationell fred och säkerhet ur ett genusperspektiv: En diskursiv studie av Säkerhetsrådets resolutioner för kvinnor, fred och säkerhet

The Security Council?s resolution 1325 addressed the major negative impact that armed conflict has on women and children. This in turn complicates the Council?s work on maintaining international peace and security. The resolution therefore highlights women?s rights as participants in peace- and conflict processes.

En energiutredning och miljöklassning av Hemsta 12:16

The purpose of this study was to implement an energy analysis and environmental evaluation of the property Hemsta 12:16 in Gävle. Based on two different methods, Energy Balance calculation and Environmental Building, the result of the property's energy use, energy performance and environmental impacts are presented. Except that, measures to reduce final energy consumption are presented.      The proposed measures can reduce energy usage by 100 400 kWh / year, which represents a decrease of 18% of the present energy usage. This would represent a total savings of 63 000 SEK per year. In addition, the environmental performance is improved by adopting the suggested measures..

Energikartläggning och energieffektiviseringsåtgärder i Zoologen på Göteborgs Universitet

The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated to the building sector and to reduce the total energy consumption real efforts need to be made to make buildings more energy efficient.The aim of this study was to investigate how energy is used in one of Göteborg University?s buildings and to find measures that can be taken to improve its energy efficiency. The chosen building Zoologen, is used for research and education.The main method of the study is computer simulations of the present building and of possible energy reducing measures to be made in the future.

När Arktis isar smälter tinar världen upp? : En kvalitativ analys av det vidgade säkerhetsbegreppet i den svenska strategin för den arktiska regionen

This study is called When the ice of the Arctic melts is the world defrosting? and written by Rebecca Fröling.The purpose of the study is to investigate how the concept ?security? is used in the Swedish arctic strategy and why the concept is described in that way. The debate of the concept ?security? has been going on for years, but the debate is still present today. What we put in to the concept is operative for how we regard and discuss security and security politics.To analyze the strategy I used two theories, one with a traditional approach and one with a critical approach to security: Realism and Copenhagen School.The method that has been applied to the study is qualitative content analysis, to be able to analyze the text on the depth.

En energieffektiv byggarbetsplats : En studie av Skanskas bostadsprojekt

The construction industry has demands on energy use in permanent buildings. How much energy that is permitted to use during the time the building is produced has no requirements. The purpose with this study is to learn how far Skanska has come with the work of making the building site more energy efficient.A literature study has been performed in the beginning of the study to survey what energy efficient arrangements that can be applied and how they operate. Using site visits and interviews the situations on the building sites have been studied as well as the energy efficient measure that are in use.Skanska has come a long way with the work of energy efficient building sites and they keep improving. They have improved half of their cabins so they use 50 % less energy.

Livsmedelssäkerhet, konflikt och hållbar fred - en teoriutvecklande studie om matens makt

In our world, more than two billion people are living under insecure food conditions and more than eight hundred million people are estimated to be starving. The majority of these people live in developing counties which are poor and often subject of civil war. The past fifty years the main subject of security analysis has been the sovereign and rational state and the threats have been viewed in terms of military and weapons of mass destruction. This has come to change over the last decades and security as a concept has broadened, which better represents the reality of today. Within this broader conceptualization of security the main referent of security is the individual, rather than the state, and threats are not only analyzed from a military point of view, but also seen as threats against human rights and freedoms.

Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder

The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..

Human Security in Serbia: A Case Study of the Economic and Personal Security of Internally Displaced Persons

The aim of this study was twofold; firstly it sought to describe the human security situation of Roma IDPs and IDPs living in collective centers, secondly it tried to create an understanding for how the human security situation can affect IDPs capabilities to develop. The findings of the study were mainly based on a field study conducted in Belgrade, Serbia for two months. The results of the study were that IDPs in collective centers have a poor human security situation regarding basic income, employment, adequate housing and experienced personal security. Roma IDPs suffer from the same insecurities, but in addition also has poor human security in basic education and personal safety. Their stagnant human security situation proved to be the result of the inability to help IDPs by the actors involved in the relief work.
