Simuleringsprogram som verktyg vid projektering av solvärme
The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.
Surhetstillståndet i bäckar uppströmskalkdoserare i Dalarnas län
The acid deposition of sulphur- and nitrogenoxides from combustion of coal and oil cause acidification that lowers pH and gives increased contents of metals and altered aquatic biodiversity in the stream. The liming of lakes and streams, which was introduced to resist the acidification, demand large economic resourses despite of the decreased deposition of the acidifyng substances. Some of the streams are influenced by the acid deposition, while others are naturally acidic. It is therefore importaint to separate the anthropogenically acidified waters from the naturally acidic, in order to optimize the use of governmental fundings for liming. This thesis aims to estimate the acidity status and impact of acidification on 24 catchments upstream liming dispensers, which is part of the liming activities at the County of Dalarna.The acidity status of the streams was classified according to the Swedish Environmental Protection Agency old classification system (Naturvårdsverket 1999) as very acid to acid, with small ability to withstand a pH-change (alkalinity) due to acid deposition.
Communication of CSR activities : a case study in the dairy sector
Recent corporate challenges require effective communication in order to secure a company?s reputation. Companies as a result, need to be committed to a series of corporate social and environmental practices along with their financial commitments to their shareholders and investors. In fact, businesses are required to go above their ordinary operations and involve all potential stakeholders that can be affected by their strategies. Companies also need to communicate social, environmental and economic consequences of their activities along with their CSR commitments to their internal and external stakeholders in order to make a better corporate image and improve their market opportunities.
Indirekta ekonomiska följder av miljödiplomering
Titel Indirect economic impacts of a national environment certification as financial business strategyAuthors Ida Antonsson, Emma Hellberg and Linn RingströmAdvisor Arne SöderbomCourse Bachelor thesis ? business administrationSeminar date 2013-05-27Purpose The main aim of this study is to describe and analyze how private corporations use national environment certifications as a business strategy to gain power and financial benefits.

Regressionsmodellering av dynamiska råemissioner från statiska mätningar
By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
Livscykelanalys av sex olika fiskodlingssystem : Fiskens miljöpåverkan för konsumtion i Stockholm
This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.
MILJÖCERTIFIERINGSSYSTEMET MILJÖBYGGNAD I PRODUKTIONEN : En fördjupning inom området ?Material?
The environmental assessment system Miljöbyggnad is a Swedish system initiated by Bygga-Bo-Dialogen to assess buildings with regards to three main areas; ?Energy?, ?Indoor climate? and ?Materials?. A building can obtain three different classifications depending on how well it manages to meet the demands. GOLD is the highest classification and is followed by SILVER and BRONZE. The majority of the measures needed to comply with the demands are done during the design phase.
Visuellt berättande i spelmiljöer
Abstrakt I den här uppsatsen undersöks hur ett narrativ kan drivas inom digitala spel enbart med hjälp av spelmiljön. Syftet är att få förståelse för vad miljöberättande behärskar som en självständig form av berättande och vad författarna kan göra för att uppnå detta mål. För att undersöka problemområdet genomfördes en spelproduktion där metoder framtagna under undersökningens gång applicerades. Produktionen testades av utomstående studenter i medieteknik och resultaten sammanställdes med reflektioner kring vad som uppnåtts och de metoder som applicerats. Undersökningen beskriver arbetsprocessen och metoder och visar hur dessa kan driva ett narrativ med en spelmiljö.
Miljöcertifierade kommersiella byggnader : Undersökning av ekonomisk ansvarsfördelning mellan hyresgäst och fastighetsägare
The Swedish commercial real estate market is in the current situation globally affected and is actively interacting with the rental and capital markets through international tenants and investors who are setting new demands on the property owners. The European Union has set new requirements as well in purpose of reducing humanity?s negative effect on the climate and therefore the international real estate market has introduced Green Building-certificates in order to decrease the real estate industry?s environmental impact.Certificated buildings with low energy consumption are a more common sight in Sweden these days. The development, however, could go even faster if there was not certain difficulties between property owners and tenants. Previous research has revealed that tenants do not always have knowledge about, or may have access to the economic benefits that a green building can provide.
Utvärdering av koldioxidmätaren Vaisala GMP343 samt sambandet mellan grundvattennivå och koldioxidavgång från torvjordar
The research group Soil and Water Management at the department of Soil and Environment at theSwedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical reasons,they plan to acquire a new type of automated field meter. The aim of this study is to evaluate thepresent meters to see how environmental conditions and instrument settings affect the results,which is meant to facilitate the introduction of the new field meter when the meters needs to becompared. As a part of the study the relationship between groundwater level and carbon dioxideemissions from peat soils will be investigated.The evaluation of the two carbon dioxide meters was made by connecting them to one single airtightsystem, with the aim of creating identical measurement environments.
Samspelet mellan ekologi, produktionsförhållande, politik och sociokulturella faktorer gällande Östersjöns torskbestånd från 1970-talet till 2003
The study begins with a historical background over the fisheries development in North America and in the Baltic Sea area in Finland and Sweden. As we can see the fisheries development depends on the interaction between ecology, state of production, politic and also social factors. In Sweden the fishery politic has changed over the period of the study. In the 1970: s the main politic focus was on the fisheries progress, expansion and rationalization. The State in Sweden took a vast part in this development and gave economic support.
CEEQUAL : Ekonomisk, social och miljömässig hållbarhet i produktionen
CEEQUAL är ett klassningssystem utvecklad av ICE, den brittiska Institutionen för Civilingenjörer, för att bättra på anläggningsbranschens sociala, ekonomiska och miljömässiga hållbarhetsarbete. Systemet utvecklades år 2003 och användes fram till år 2011 endast i Storbritannien och Irland. År 2011 utvecklades en internationell version för organisationer som är intresserade av att certifiera projekt i andra delar av världen.Syftet med rapporten är att utvärdera konsekvenser för ett projekt som skall miljöcertifieras. Detta sker med hjälp av tre fallstudier från Skanska Sverige AB:Projekt Skarplöt, exploatering av en åkermark i Västerhaninge.Projekt Folkparksvägen, ombyggnation av en 1500 meter vägsträcka.Projekt Tyresövägen-Simvägen, en avsmalning av Tyresövägen från motorvägsstandard till stadsväg. Målet med rapporten är att:Identifiera förbättringsåtgärder för att främja hållbarhet och resurseffektivitet i produktion.Uppskatta vilka resurser förbättringsåtgärderna för certifiering kräver.Resultat från fallstudierna visar att Skanska har väl inarbetade rutiner i företagets ledningssystem, dock finns det förbättringspotential som kan uppnås med integrering av CEEQUALs krav i dagens arbetssätt.Merkostnaden av förbättringsåtgärderna består mestadels av tjänstemannatid för ett utökat samhällsengagemang, planering och bevakning av åtgärder som främjar hållbarhet samt insamling av bevismaterial för certifiering.

Background and problem: Higher and other demands are made on management control systems in organizations which have a superior non-financial objective. Systembolaget, a state-owned company with monopoly to sell alcoholic beverages in Sweden, combines two main objectives which can be considered as conflicting, one financial target and one superior non-financial public welfare target. The research questions are focused on the translation of information through the organization?s levels and if the management control system makes it possible to run the organization according to both of the two main conflicting objectives.Purpose and Delimitations: To describe, analyze and evaluate how management control can be used in an organization, which is not profit maximizing and has both non-financial and financial objectives. The essay does not try to describe or draw generalized conclusions regarding general perspectives on Systembolaget?s assignment and objectives.Method: A qualitative and evaluative case study based on interviews with five employees at different levels in Systembolaget has been carried through.
Hållbar utveckling i högre utbildning : Miljöledningssystem användbart för akademin?
The purpose of this report was to investigate how the Umeå School of Business and Economics at Umeå university can work to increase the share of courses and programmes that discuss sustainable development. Furthermore the purpose was to develop an action plan that can be used to increase that share. Methods used were a questionnaire directed towards the educators at the Umeå School of Business and Economics and an assessment of the content of courses and programmes connected to the Umeå School of Business and Economics. There was no clear structured way of working with education for sustainable development, but at the same time there was a will to integrate sustainable development in the education. Curricula were according to the educators an important tool to achieve this integration, their experience were that there are not enough time, people and money to work with sustainable development in the education and they would like to see more clear directions from the management.
