Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn
The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.
Jakten på miljömässig effektivitet : - en fallstudie av miljöarbetet på tekniska förvaltningen i Växjö kommun och Södra Timber
Bakgrund: För att bedriva ett framgångsrikt miljöarbete kan företagen använda sig av olika hjälpmedel och verktyg. Ett exempel på ett sådant verktyg är ett miljöledningssystem. Det har diskuterats om miljöledningssystem i sig leder till miljömässig effektivitet. Det som anses vara av större vikt är på vilket sätt företag arbetar med miljöledningssystem.Syfte: Vårt syfte är att beskriva hur miljöarbete bedrivs och förklara om det bedrivs på ett sätt som gör att den miljömässiga effektiviteten i våra fallföretag kan förbättras. Ett delsyfte är också att undersöka om det finns någon skillnad i arbetssätt gällande miljöfrågor beroende på om verksamheten är offentlig eller privat.Metod:.
Trädetaljer i exteriör arkitektur : En rapport om hur arkitekturen kan tillåtas framhäva trä som byggnadsmaterial i utvalda exteriöra detaljer för ett äldreboende med massiv trästomme
Arkitektfirman Kolman X Boye Architects har fått uppdraget att upprätta bygglovshandlingar för ett äldreboende. Det är ännu ej bestämt i detalj hur byggnaden skall uppföras men beställaren önskar att byggnaden uppförs i träbyggnadsteknik. Äldreboendet projekteras för 54 stycken lägenheter fördelat på sex stycken våningsplan och en total bruttoarea på strax under 6000m2. Ingen lika hög träbyggnad med denna verksamhetsklass avseende brand har tidigare uppförts i Sverige.Vår uppgift och utmaning i detta arbete har varit att reda ut problematiken kring projekteringen av exteriöra detaljer för höga hus i trä. Utifrån kända problem avseende brand, akustik och fukt har sedan ett antal detaljer som påverkar det estetiska uttrycket projekterats.

Mortalitet och skottskjutningsförmåga hos ek (Quercus robur) efter brand :
In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study
consisted of two separate field tests; in the first, two 300 m2- plots in western oak
dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height). At the end of the season almost 50% of the oak seedlings had resprouted while the beech seedlings had 100% mortality. An attempt to investigate the effect of the burn of artificially sown acorns was totally ruined by wild boar grouting before any conclusive results could be seen.
In the second test the resprouting ability of oaks of varying diameters (average BHD 7-9 cm, range 2-42 cm) was examined one season after a prescribed burn in southeastern Sweden.
Utvärdering av CTI på virkesfordon : ? CTI-projekt Holmen Skog/Örnfrakt 2005-2006
The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility
Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure.
The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.

Åtgärdsförslag och känslighetsanalys vid energieffektivisering ur ett fuktsäkert perspektiv : En fallstudie på timmerhuset Sofiedals herrgård
This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.
Skogsbrukets erfarenheter av Poppel Populus sp. i Skåne :
In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species.
The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.

Privatskogsägarens nettoinkomst vid avverkning under perioden 1952-2008
During the period 1952-2008, real prices of wood before taxes and charges declined. However, the actual net income has not changed by the same percentage as the price list, because taxation, driving costs and the ability to make deductions has changed. This report considers the inflation by using the Swedish consumer price index. Net income refers to the remaining income when relevant costs, taxes and fees have been paid.The purpose of this study was to examine how the private forest owner's real net income has evolved over the period 1952-2008 for three categories of forest owners. These three categories are1.

covering one month consumptian of timber in a large sawmill.
County Branding : En studie i kommuners marknadsföring mot företag
There is a mutual dependency between the business world and the country?s municipalities. The municipalities are dependent on the companies to create work and tax income while the companies are dependent on the municipalities they are located in to provide good infrastructure among other things.Apart from this the municipalities can work activly with creating a strong brand in the eyes of the companies and many researchers in marketing agree that marketing of places will be more common in the future. Marketing of municipalities is however still a rather new and unexplored area and it is uncertain how and to what extent the municipalities work with this.The thesis is formulated:How are the municipalities working to market towards companies and is it possible to make out any positive change from these marketing efforts?The goal of this study is:Our goal is to examine how the view of marketing of places differs from different municipalities in the Stockholm region, how some of these municipalities work with this and how far they have come in this work.
