In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept which is far more complicated than measuring how much built surface that needs to be covered. It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.

Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

Ett branschanpassat affärssystem är avsett för organisationer verksamma inom samma bransch. Syftet med denna typ av affärssystem är att ge högre passform än standardiserade affärssystem och vara billigare än skräddarsydda affärssystem. Det råder dock brist på kunskap om hur dessa ska utvecklas. Genom vår litteraturstudie presenteras en kravinsamlingsmodell med utgångspunkt i Requirements Engineering som ska ge stöd för utvecklare vid insamling av krav för branschanpassade affärssystem. Utöver det identifierades ett flertal aktiviteter relaterade till modellen.

The purpose of this study is to investigate how much of the estimated annual electric energy production from Swedish wind power that actually was produced, as well as the history of this agreement over time. The aim is to also examine if there are properties that have caused some group of wind power plants to produce more or less, compared to their estimated production. Operational data on wind turbines collected by the Swedish Energy Agency was analyzed. A survey was made among owners of wind power plants with a nominal power of at least 2 MW. Two different methods for normal year correction of production data were used and compared.

ABSTRACT The potato has had an important role in the Swedish dietary customs for quite some time. However, during the last forty years, consumption has decreased from 87 kg/year and person to 46 kg/year and person. Other products such as pasta, rice and bulgur are competing with the potato. Many of the competitors have been developed and refined while the potato has not changed much. The potato is still a bulk product while competing products have been differentiated. Stakeholders within the potato market has realized that something has to be done and today there are a number of organizations and networks that all actively work to preserve the Swedish agriculture and specifically the potato as a product. The purpose with this essay is to examine how store managers in the Swedish grocery stores view the handling of the potato in the store, the quality and packaging, marketing and future consumption.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

För att minska energiförbrukningen i Sverige krävs att befintliga byggnaderen ergieffektiviseras. Det finns även befintliga lokaler i landet som är i behov av en sänkt energiförbrukning. Det sker ständigt initiativ kring arbete med energieffektivisering av framför allt bostadshus. När energiförbrukning ska sänkas i industrilokaler läggs fokus på att minska energiåtgången i de invändigaprocesserna men inte i det omgivande klimatskalet där transmissionen utgör en stor del av energiläckaget. Syftet med arbetet är att öka kunskapen om energieffektiva åtgärder vid renovering av klimatskal hos industrilokaler.

The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.

Entrepreneurial firms face unique challenges in attracting and acquiring human resources due to difficulties associated with resource constraint and organization legitimacy, often described as liabilities of "smallness" and "newness". The aim of this paper is to examine the "smallness" and "newness" challenges met by small entrepreneurial firms, which strategies they apply to counter these challenges, and if these strategies can be explained by the firm's HR philosophy. Since few studies on Human Resource Management (HRM) in small entrepreneurial firms exist, a framework combining theory from the research fields of HRM, entrepreneurship and small firms has been developed. Employing a qualitative case study design of five small Swedish entrepreneurial firms, our findings demonstrate four "smallness" and "newness" challenges and seven strategies that either counteract or prevent them. Furthermore, results showed that the strategies applied seemed to have no significance with regards to the firm's HR philosophy.

Dagens samhälle är präglat av materialism och dagens konsumtionsmönster är ohållbara ur miljömässig synpunkt. Konsumtionen skapar därmed miljöproblem och ett viktigt styrmedel för att göra den mer hållbar är miljömärkning. Miljömärkta produkter produceras på ett miljöansvarigt sätt utan kemiska bekämpningsmedel och gödsel som är skadliga för både människa och miljö. Syftet med denna studie var att undersöka den nuvarande medvetenheten kring miljömärkningar hos unga vuxna på Möckelngymnasiet. Metoden för studien var enkätutdelning till skolklasser som går sista året på gymnasiet.

We examined why file sharing is such a widespread phenomenon and what drives the persons that using file sharing, and what consequences it has on their consuming and ownership. We reached our goal by interviewing ten people who download files, using a qualitative method. We present the internet community where sharing files, copyright and the IPRED law are important ingredients for how the new generation consumer?s patterns look like. Today you can travel all over the world with a push on a button in just a few seconds.

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.

Denna magisteruppsats handlar om vilken betydelse Human Resource arbetet har för kompetensutvecklingen inom två olika organisationer. Under senare år har relativt stora satsningar gjorts på personalutbildning och andra kompetensutvecklingsinsatser i arbetslivet. Forskning har visat att kunskapsproduktionen i samhället ökar ständigt och för att finna en lösning på detta har många företag valt att satsa på kompetensutveckling. Det bakomliggande antagandet har varit att det i allt högre grad är kunskap och kompetens än kapital som växer i framtiden. Därför bör såväl privata som offentliga organisationer satsa på kompetensutveckling både kortsiktligt och långsiktligt för att kunna möta de framtida kraven.

Human Resource Management (HRM) handlar om att leda mänskliga resurser. Det blir det allt vanligare att personalansvaret delegeras till linjecheferna i organisationen eftersom de arbetar närmast de anställda. Syftet med denna studie var att med kvalitativ metod undersöka på vilket sätt chefers arbetssituation skiljer sig åt mellan de som har, respektive inte har, en HR-avdelning att tillgå. Studien baserades på nio enskilda intervjuer vilka tolkades enligt induktiv tematisk analysmetod. Resultatet visade att personalarbetet var mer integrerat i det dagliga chefsarbetet på företag som hade HR-avdelning, och dessa chefer kände sig inte stressade av personalansvaret i sig.
