Det kan vara farligt att ligga lågt - om stadsplanering inför stigande vattennivåer : Exempel från Göteborg, Kristianstad och Arvika

In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.

Utvärdering av VAV i nybyggt kontorshus

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Biogas på Wapnö : Analys av framtida energisystem

Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.

Organisationskultur i förändring ? Subkulturers inverkan och respons på förändring

AbstractBackground: The company that this report addresses is, at time for investigation, in the midst ofa change in organizational culture, where two departments with different core competencies arebrought together into one. The purpose of this study is to review the potential problems that mayoccur in the change process when one or more subcultures come into conflict with organizationalgoals.Purpose and methodology: The reason for performing this study and the objectives are toexamine how subcultures influence and respond to organizational changes. The survey isconducted with a bottom-up approach in which participation in daily activities with thesubgroups is the foundation. The management's perspective has been omitted in consideration ofpast literature in the field where focus most often has been on their thoughts and views on theprocess of organizational change. The method used is participant observation and interviews.Results and Conclusion: Subcultures exist and they do affect an organizational change.

Den svenska regeringens förvirrade klimatarbete

The aim of this study is to clarify the Swedish government?s purpose of participating in theEuropean Union Emission Trading Scheme. Taking as its departure point state-centricinternational political economy this study presents three plausible hypotheses on what thepurpose might be. Either it is to promote consumers interests, or to promote the Swedishnational climate goal ?Reduced impact on climate?, or to promote the profit of Swedishcompanies.

Gaspotentialen i en deponi, idag och i en framtid :

Deposited waste material degrades within a short period in anaerobic environments. The methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of methane gas that might be produced in the landfill in the future.

Organisationsförändring ? hot eller utmaning

Working life changes, just like the rest of today?s society, at an accelerated pace. It is through changes and challenges that human beings develop, personally and professionally. Changes are often met by resistance. The purpose of this study is to see how different factors influence individuals? experiences of change.

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..

Förändring som styrmedel  : En studie av implementering av nya rutiner på IKEA Örebro

This paper aims to study the Armenakis´ theory of readiness, "are they ready?", which consists of five key components affecting the outcome of an organizational change. In this case study, the intention is to investigate if any component is important; alternatively if it is possible to discern a pattern between components, i.e. how they correspond to each other. During the past 30 years have a research group lead by Armenakis has studied organizational change and how resistance to change can be avoided by preparing employees in the introductory phase of change. The main object for Armenakis is the question "what determines whether the employees (change recipients) adopt and support, or reject and resist a change".

Om samspel och gruppklimat i arbetsgruppen : En kvalitativ studie om samspelets och gruppklimatets betydelse för arbetsgruppens gemensamma psykosociala arbetsmiljö

The purpose of this paper is to identify significant factors of influence for the co-existence and team climate within working groups, and to examine their impact on the psychosocial work environment within a group. Team climate and interaction affect every individual in a group. The manager, however, is the one formally accountable for the psychosocial climate in a working group, which is the reason why this study uses the management perspective.As an introduction to the empiric study, an overview of the existing literature within the field was made. A qualitative method is used and the empiric data is based on semi-structured interviews. The study comprises six interviews with department managers within the Social Services in the City Council of Stockholm.

Termohalin cirkulation i Nordatlanten

Den termohalina cirkulationen är en global havscirkulation driven av densitetsskillnader, som gör att varmt vatten transporteras mot polerna och kallt vatten mot ekvatorn. Densiteten påverkas av temperatur och salinitet (och tryck, som vanligtvis ignoreras). Därför heter cirkulationen termohalin. Saliniteten minskar när vatten tillförs genom nederbörd, havsissmältning eller landavrinning. Saliniteten ökar genom avdunstning och isbildning.

Den främsta förändringen i vardagsarbetet: en studie av bibliotekariers syn på förändring och stabilitet i arbetet

The main purpose of this Master?s thesis is to examine what librarians in seven public libraries experience as major change in their work tasks. We are also interested in exploring how these changes influence librarians? ways of working. In addition to this we want to explore if librarians have experienced change in relation to user?s expectations and demands and if so, how they are met.

Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.

Ekonomi i Passivhus : En studie av två verkliga byggnader

The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.
