SmÄskalig sÀsongslagring av solenergi för uppvÀrmning av bostÀder : Simulering av lagerutformning och konsekvensen av adderade uppvÀrmningsbehov motsvarande en pool och ett atrium
The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.
LinjenÀtsutredning i TÀby kommun.
The public transport network in TĂ€by commune consists currently of two types of bus line of whichboth belong to the category of feeder lines. The first type terminates at Danderyds sjukhus and feedsto the subway whereas the second type terminates at TĂ€by centrum and feeds to Roslagsbanan, asuburban narrow-gauge railway system in northern Stockholm. The trunk bus line that connectsgreater parts of the commune with Danderyd is the ring line 604 and goes both clockwise (604H) andcounterclockwise (604V). The main negative aspect of this structure is the complicity in incorporatingit timetable-wise with other bus lines that share the same route, such as through Enebyberg.The goal of this project is to investigate the possibilities of splitting ring line 604 and connecting theends to two different bus routes that terminate at TĂ€by centrum today. Apart from easing thecoordination with other bus lines through Enebyberg, the extension also creates new directconnections from various areas in TĂ€by to Danderyds sjukhus.
Besökarstudie i Kilsbergens rekreationsomrÄden : en metod för att utveckla rekreationsmöjligheter pÄ Sveaskogs marker
In this Master thesis an effective method is presented to find out what is requested in a forest or outdoor recreation. The aim with the study is to find out how Sveaskog can increase the general interest for experiences in nature and improve the access for recreation. Some questions that have been used to answer this purpose are: Who is visiting/not visiting the recreation area? How is it possible to increase the number of visits? The study is carried out in Kilsbergen and mainly centered around Ă
nnaboda, which is the natural place for people to meet at and undertake recreational activities.
The method that is used is a mail-survey that was sent to visitors and people living in Ărebro. People living in Ărebro represent potential visitors who live close to the recreation area.
Gotland ponies on extensive pastures ? a welfare assessment
Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition.
The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare QualityÂź project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed.
Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.
Undersökning av luftkvaliteten vid smÄskalig biobrÀnsleförbrÀnning i tvÄ kommuner med modellsystemet VEDAIR
An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 ”m) in two Swedish municipalities, VÀnersborg and Gnosjö, is introduced.According to the result, there are areas with poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In VÀnersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 ”g/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Framtidens energieffektiva flerbostadshus
The housing sector of today represents for almost 40% of the energy consumption, an energy consumption of which the major part consists of non-renewable energy sources. This is not sustainable and utilization of new energy-efficient technologies in buildings can be a step in the right direction, towards a sustainable energy society.This report has been made on behalf of and in cooperation with Ălvstranden Utveckling AB in Gothenburg to examine how future energy-efficient technologies can affect the energy demand in energy-efficient multi-dwelling buildings.The report is based on Ălvstrandens passive house, Hamnhuset, a house whose energy consumption is far below the BBR's requirements. The report looks at the opportunities for improvement within windows, insulation, solar energy technologies, as well as white goods. Computer simulations are then made to apply the selected technologies into a reference building. Technologies are selected from an energy efficient perspective and no account has been taken of other aspects such as the economy.

Torvströ till svenska mjölkkor :
Peat litter is a soft material with high absorbency. About hundred years ago many farmers in Sweden used peat litter to their dairy cows. After the World War II the use of peat litter decreased and the farmers used more straw. Nowadays (year 2007), when it is harder to find straw and sawdust to buy, peat litter is advancing again. The purpose with this study is to investigate peat as a litter to dairy cows.
Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64
The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.
Renkavlens biologi - möjligheter till kontroll
Renkavle har under lĂ„ng tid varit ett stort problem för lantbrukare i stora delar av norra Europa och har etablerat sig pĂ„ större arealer Ă€ven i Sverige. Genom sin bio-logi Ă€r renkavle mycket vĂ€l anpassad till odling av höstsĂ„dd spannmĂ„l, speciellt i kombination med reducerad jordbearbetning. Det finns en ökande trend av bĂ„de höstsĂ„dd spannmĂ„l och reducerad jordbearbetning som talar för att problemen med renkavle kommer att öka framöver. Ăven den pĂ„gĂ„ende klimatförĂ€ndringen mot ett varmare klimat i Sverige förbĂ€ttrar förutsĂ€ttningarna för att renkavle ska etablera sig lĂ€ngre norrut. Renkavle Ă€r ett ogrĂ€s som krĂ€ver en mycket hög grad av kontroll för att inte öka kommande Ă„r eftersom fröproduktionen hos renkavle kan vara mycket stor.

Ligghall för utegÄngsdjur ? en sammanstÀllning och analys av domar i djurskyddsÀrenden som handlar om ligghall till utegÄngsdjur Ären 2007-2013
There is currently an ongoing discussion in Sweden about the need for weather shelter for farm animals being kept outdoors during the winter season. Currently, the national animal welfare legislation requires weather shelter providing the animals? with access to a dry and clean place to rest, but under certain conditions exemptions can be granted. The Swedish Board of Agriculture has put forward a hypothesis that there is a difference between judicial decisions in animal welfare cases dealing with weather shelters, as to whether the animal has shown to be suffering or not. The aim of the study was to highlight any weaknesses or difficulties when assessing animal welfare issues associated to the absence of or design of weather shelters.
Inverkan av utfodringsnivÄ och miljö pÄ reproduktion och hÄllbarhet hos rekryteringskvigor :
This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.
LjussÀttning av det lilla trÀdgÄrdsrummet :
Sammanfattning
Eftsom kalla Sverige blir mörkt ganska tidigt pÄ kvÀllen pÄ höst, vinter och vÄr ville jag se hur man kunde förlÀnga anvÀndandet av det lilla trÀdgÄrdsrummet bÄde i tid pÄ dygnet och i tid pÄ sÀsongen. Jag tycker att ljussÀttning Àr en viktig del av gestaltningen, belysningen gör trÀdgÄrden levande. Mitt syfte med arbetet var att skaffa mig grundlÀggande kunskap om ljussÀttning och ljuskÀllor, för att sedan skissa pÄ koncept för det lilla trÀdgÄrdsrummet.
För att lyckas med detta behövde jag ta reda vad ljus Àr och hur det fungerar. Ljuset har mÄnga olika egenskaper, t ex olika vÄglÀngder, och fÀrger.
