BOSTADSUTVECKLING & SOCIAL HÅLLBARHET : JM AB:s projektutveckling och dess sociala effekter
This report tries to discuss the concept of social sustainability; what it means and how residential development can be made more socially sustainable. This is done by interviewing several and various representatives in JM AB, the municipality of Uppsala and residents of Åriket to explore how JM AB as a housing developer and the municipality are working with issues regarding social sustainability and what the residents in one of the new housing projects themselves think of these issues. The result of these interviews will be compared and analyzed with the prospect of finding common variables and hopefully ways of improvement.This will result in our own recommendations of areas of improvement either by broad initiatives or specific actions to increase the social sustainability. Areas such as meeting places, sustainable functions and joint efforts between different parties. During the work on the report we come in contact with several other areas of interest that we are not able to process ourselves and therefore recommend them for future studies..
Energisparläge i automationsindustrin : Potential för att minska tomgångsförluster med industriella styrsystem

The main part of the thesis consists of a case study performed on machine tools at a Scania production site in Södertälje. Through load measurements the potential for energy savings was determined.The results show that there is a great potential for energy savings during idle times at the site.
Effektiviseringsåtgärder i tryckluftsystemet hos Vattenfall Värme Uppsala
In this work an assessment of the compressed air system in the facilities of Vattenfall Heat Uppsala has been conducted. The facilities constitutes, among others, a combined heat and power plant, and two waste incineration plants. The compressed air is supplied primarily by seven rotary screw compressors and yearly electric energy consumption in these has been determined. Furthermore, the usage of compressed air has been mapped in order to find processes with energy savings potential. Several suggestions how to reduce the usage of compressed air have been presented, resulting in decreased need of electric energy and reduced CO2-emissions.The results show that total need of electric energy in the compressors, during a standard production year, amounts to 5.83 GWh.

Har energidryck någon kognitiv effekt i kombination med alkohol? : Med fokus på komponeneten koffein
Background: Energy drinks have been found in everyday-stores since 1997 and their popularity have increased over time. Consumtion of energy drinks takes place because of their ability to increase concentration and to decrease fatigue but also because of the popularity the drinks have got. Target groups for these stimulating beverages are adolescents and young adults. Energy drinks contain caffeine, taurine, glucuronolacton, carbohydrates and B-vitamins and voices have been raised about the eligibility for young people to ingest large quantities of these kinds of substances. Because of the properties of these substances it has become popular to mix energy drinks and alcoholic beverages to make up for the negative effects of alcohol and to be able to drink larger quantaties.Aim: The aim of this literature work was to investigate cognitive effects of the combination of caffeine in terms of energy drinks and alcohol and to determine if these effects could be harmful.Method: This literature work is based on five scientific articles retrieved from PubMed.
Förnybar energi ur ett kvinnligt och manligt perspektiv : En attitydundersökning med avseende på att kartlägga hur synen på fönybar energi påverkas av om individen är kvinna eller man
Abstract The extraction and usage of energy give rise to immense environmental problems which helps to accelerate climate change. Energy is an important resource for the community and there are a variety of different types of energy sources available, that are either classified as renewable or non-renewable energy sources. The usage of renewable energy sources cause less environmental impact than the usage of non-renewable energy, which in turn means that the energy?s strain on the environment is strongly affected by the type of energy source used.The aim of the study is to describe to what extent attitudes towards renewable energy are affected by whether the individual is male or female, by examining the hypothesis regarding how women have a closer connection to nature and to a larger extent shows on an pro-environmentally friendly behavior than men, and if it also can be detected on issues related to renewable energy and thus imply that women have a friendlier approach towards renewable energy than men. A number of ecofeminist believe that women have a stronger bond with the nature through her embodiment as a woman and by her maternal role, which according to previous research also leads to the fact that women shows on a more extensive environmental behavior.Through a qualitative research method in the form of semi-structured interviews has three female and three male respondents been asked questions with regards to the environment, individual responsibility and energy.
HÅLLBART BYGGANDEMED HJÄLP AV BIM : Effektiva energianalyser och LCC
The society strives for sustainable development, in the construction industry it is expressed through sustainable building. Energy and LCC analyzes increases the ability to make conscious decisions in the process. A problem in the construction industry is that energy and LCC analysis is not used to the desired extent, as they are perceived as complicated and time consuming. The report aims to achieve a more sustainable building through increased use of energy and LCC analyzes.The goal is to show how BIM can be used to improve the efficiency of the energy and LCC analyzes.The study was conducted with a literature review and a case study to answer which information that is required in a BIM model to perform energy and LCC analyzes. The study also shows which software can be used in BIM based energy and LCC analyzes and how the analyzes can be carried out efficiently.The result shows that effective analyzes may be performed if the BIM-model contains the relevant information for making analyzes.
Hållbar utveckling-en studie av små- och medelstora företag i Sverige
Sustainability has become more interesting to several companies through the last years, the trend attracts lots of attention around sustainability. Sustainable development means different to different people. The most frequent definition that we have found and which we believes compare with our definition of sustainable development.?a social change which satisfies daily needs without endanger next generation?s possibilities to satisfy their needs?.We have in this project commence from the English word sustainability and establish our own apprehension of its meaning, in the Swedish translation we have chose to call it sustainable development.This study is a part of an extensive project which is going on around the world and the material of the empirical study is designed after the international variation.Our study on over fifty small and medium sized enterprises has got the conclusion about what they think of sustainable development. We have compiled their answers and then the answers have been divided in three main categories.These main categories are:? Environmental-? Social-? Economic sustainabilityWe have also described what kind of obstacles which can be considered as standstill?s in the work with sustainable development, we have been summery them in three main categories:? Time? Cost? KnowledgeWe have seen that enterprises mostly see it as an competitive advantage to work with the main categories which is included in sustainable development, but the three standstill?s makes it difficult fore them to reach right up to sustainable development..

Infallsvinklar och angreppssa?tt fo?r en svensk livsmedelsstrategi : En utredning av angreppspunkter och betraktelsesa?tt hos livsmedelsstrategi-intressenter samt ha?llbarhetsaspekter av dessa.
Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.
Smarta lokala energisystem, Vision-Teknik-Tillämpning
The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
Hur påverkar energi- och proteinrik kost intaget av energi och makronutrienter?
Today 70 percent of the people residing in nursing homes are undernourished. One way to avoid that an individual is affected by malnutrition it is a necessity that the meals is customized after special needs current among other things as energy and protein. Food record is a method that can be used to examine and evaluate if an individual is getting sufficient nutrition and energy to cover the daily needs. For those suffering from malnutrition it is recommended to eat energy and protein enriched diet.AimsThe aim is to compare the intake of energy and macronutrients in a group of elderly people living in a nursing home in southern Sweden before and after the introduction of an energy and protein enriched diet based on newly developed recipes.MethodsFood record was made during four days. Food record means that everything that is consumed by an individual is noted precisely.
