AbstractThe indoor environment affects the human performance. Noise pollution, poor lightning and coloring are some of the factors that affect our work performance. The human is also affected by the air change and temperature, these factors are in most buildings possible to adjust and through this make economic savings. To find out about the indoor environment in the O-building a questionnaire was handed out, measurements/surveys and an interview was also made. 108 questionnaires where handed out to employees and students.

The purpose of this investigation is mainly to study if pupils have enough knowledge concerning the water cycle and the life of the plants?, and what kinds of household word they have, to discuss pollution within these areas. I also studied how the pupils? knowledge are holding up against what the course-plans says, since it have come to light by other investigations that knowledge are insufficient within the nature-oriented (No) subject in school.The survey has carried out on 28 pupils in a 5th grade, with help of a questionnaire survey. Their teacher has been interviewed and I have studied their local course-plans and also the pupils? schoolbooks in No.The result of the questionnaire survey indicates that the pupils had insufficient knowledge within the areas of plants? life and pollution, something their teacher had a presentiment about.The conclusion is that they need to go out more often in the nature and see how the plants and the environment are affected by different factors.

The goal with this examination thesis is to investigate the difference in carbon dioxide emissions between a building with a wooden versus concrete carcassing from a life cycle perspective. The huge amounts of carbon dioxide released into air from human activities must be reduced to prevent serious consequences. A way to limit this issue is through performing a comparative study where the result shows which of two products with the same function has the lowest emission of carbon dioxide, whereof the product with the lowest carbon dioxide pollution can be chosen.To be able to perform a study like this an object has been chosen and studies about life cycle analyses have been done. The rental square meter, the thermal conductivity value, the energy requirements and the placement of the building has been set equal in both framework types. There were solely dissimilarities of the two buildings taken into account when this comparison study was performed.The result of the study is that a building constructed with a wooden carcassing has the lowest amount of carbon dioxide emissions.

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to Noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Landscape architects has many ways of transforming our cities and landscapes. Traditionally, most attention has been put to visual qualities. Pen and paper are well established as the way to present proposals and to analyse in the landscape architects profession and training. But are we perhaps missing out on other ways of seeing the landscape? The purpose of this paper is to present sound as a tool of transformation. Sound in public spaces has long been treated just as noise and therefore unwanted.

The main purpose of this study is to clarify the underlying reasons as to why people choose to travel by car or taxi, and to do so by using people´s choice of transportation to and from Arlanda Airport as an example. Furthermore it is also in our interest to see what changes are needed to make more travellers use the available public transportation.Because of the increasing pollution rate from the means of conveyance headed to and from Arlanda Airport, Luftfartsverket is attempting to decrease the amount of emission from the connecting transportation sources. Luftfartsverket has a pollution limit which is about to be reached in a few years, based on a prognosis made by Arlanda´s office of environmental issues. In order to investigate people´s travel mode choice a survey was conducted at Arlanda Airport, Stockholm. 82 travellers were interviewed on a three day basis inside terminal 4 and 5.

A controlled recording in a studio is the basis of all voice treatment. However, this controlled way of recording voice patients' voices can be questioned. The voice use may be different in a natural environment. In children noise related voice problems are investigated in a study about voice and its development (BUG ? Child voice and noise).

Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.

City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise barriers.

Stormwater from trafficked areas often contains high pollution levels. In traditional stormwater management design, stormwater is first transported away through piped networks, and then in most cases passes through oil separators before finally reaching the recipients. While this traditional method removes certain pollutants from the stormwater, it does not reduce the total flow, as in the case of ecological stormwater management. In the ecological method the stormwater is not simply transported away, but is recirculated through infiltration, percolation, and detention. The aim of this study is to investigate possible advantages of ecological management designs, in contrast to traditional management.

The EU's Water Framework Directive aims to a long-term and sustainable use of our water resources and wants to ensure good water quality in Europe's water bodies. Discharge of polluted stormwater into receiving waters can be a threat to their ecological and chemical status. Municipalities are responsible for supervision of the environmental quality standards (EQS) and therefore need to gain knowledge of current stormwater management, the expected level of pollution emissions and possible appropriate purification steps to ensure that the goal of good water quality is achieved.This master thesis aims to provide this knowledge in the example case of Vallentunas urban area and wants to prepare future oversight so that it can be assessed how much the discharge of polluted stormwater into the local receiving water is a threat to its status. With the help of maps, aerial photographs, site observations and individual discussions those areas are mapped where appearance of moderate to highly polluted stormwater could be suspected. The degree of pollution at the discharge points is determined based on land use upstream and uses standard values according to the administrators assistance "Tillsyn av dagvatten" (MSL 2014).The study identifies 100 areas in need of supervision regarding their stormwater management.

This thesis aims to increase understanding and knowledge of issues affecting the redevelopment of older office buildings to housing. The rising demand for housing in recent years has resulted in a need and an increase in cost housing projects. The need has led property owners wanting to build old office buildings to apartments. The case study is carried out in Lycksele town and in close contact with consultancy TM (Technician Mercantile) ? consulting, which has operations in the area.

Den bullerreducerande beläggnigen har en porös struktur som förbättrar dräneringen och reducerar buller vid källan men egenskaperna orsakar ett snabbt slitage och portäppning. Detta medför att beläggningen måste omläggas och rengöras oftare än en konventionell beläggning som t.ex. ABS 16. Kritiken mot den bullerreducerande beläggningen riktar sig på de höga drift- och underhållskostnaderna, detta gör att många väghållaren satsar på bullerskärm som bulleråtgärd.  Syftet med arbetet är att jämföra bullerreducerande beläggning med bullerskärm, för att reda på vilken bulleråtgärd är mer kostnadseffektivt under 20 år. Ett teoriavsnitt kommer att förklara och beskriva på ett tekniskt sätt: väg, ljud och buller, bullerskärm och bullerreducerande beläggningar.Kostnadsjämförelsen mellan bulleråtgärderna omfattar investering, drift och underhåll.

There are a lot of different sounds in our sound saturated time. Noise is an unwishable soundand a high sound level can give short- or lingering problems for both children and adults.The purpose was to find out if and in that case why children and the activity at the pre-schoolaffects by a high soundlevel. Another purpose was to examine what the effects would be if thepedagogues set about the work to get a good sound environment at pre-school.The investigation was accomplished in shape of qualitative interwievs where six pedagoguesfrom different pre-schools answered questions about a high soundlevel.All of them have been educated to hearing pilotes.The result of this investigation shows that some pre-schools have a high sound levels but notall of them. In those cases where there is a high soundlevel are there often too many childrenat the same place on the same time. That makes the soundlevel even higher and both childrenand adults are getting tired.By improving the sound environment at the pre-school both children and adults often gets abetter activity.Keywords: high soundlevel, hearingpilot, noise, affects on children..
