This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight Timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.

Omorganiseringar sker ofta när organisationer stöter på motgång och därför är tvungna att göra någon form av förändring. Det saknas i dagsläget forskning hur en förändring uppfattas ur en medarbetsarutgångspunkt. Denna studie har utförts vid SCA Timber ABs fem markandsavdelningar och syftet med denna studiehar varit att ge en multidimensionell bild av en förändringsledning ur ett medarbetar- och ledningsperspektiv samt att ta reda på hur de kan kontrasteras. De teorier som har använts har verkat som en grund för, och har väglett analysen. Studien har varit av kvalitativ typ och den metod som har använts bygger på en narrativ ansats.

In Sweden, large scale planting of Lodgepole pine (Pinus contorta var. latifolia) started in the beginning of the 1970?s. At first, the aim was production of pulpwood, but later, also production of Timber became considered realistic. Today, Sweden has more than 520 000 ha of Lodgepole pine.

Sweden is a country with few native tree species. According to Govt. 2007/08: 108, exotic tree species may be seen as an opportunity to increase the growth of tree volume in Sweden. Potential areas where explored In this work for cultivation with Pinus contorta var. latifolia Engelm., Larix sukaczewii Dylis, Abies lasiocarpa (Hook.) Nutt., Populus × wettsteinii Hämet-Ahti (tremula x tremuloides) and Picea mariana (Mill.) Britton et.al.

Det övergripande syftet med denna studie är att bidra till kunskap om hur dagens urbanamänniska använder sig av skogens ätliga resurser, såsom svamp och bär. Dessa resurser kallas iforskningssammanhang ofta för non-Timber forest products (NTFP). Användningen av NTFP harbelysts ur ett kulturellt perspektiv och undersökts som tradition, det vill säga kunskap somtraderas mellan generationer. Fokus har legat på hur vanor förändras över tid och rum, vad debetyder för personer i gruppen och hur de vidareförmedlas. För att avgränsa studien är detgruppen Personer med polsk bakgrund boende i Stockholm (PPBS) som har undersökts.

SUMMARY Establish a pasture There is many valuable nature and culture landscapes in Sweden that has developed during a long period of time, throw natural processes or human use. Unfortunately lot of these are disappearing. My thought with this work is to explore the possibility to establish new areas with similar qualities. The motive for this is that attractive countryside biotopes are well worth to use as model to enrich the urban landscape. Another thought has concerned the people that establish, build and manage landscapes and parks. They often have varied views, both coming from a difference in background and previous experiences.

Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northernhemisphere, including Sweden. New results indicate that pre?commercial thinnings could be at riskfor Heterobasidion spp. infections.

Den hårda konkurrensen på trävarumarknaden har tillsammans med en tuff valutasituation gjort att svenska sågverk drabbats mycket hårt. SCA har tvingats stänga sina sågverk i Vilhelmina och Holmsund bland annat på grund av valutasituationen. Enligt Jonas Mårtensson (VD på SCA Timber) befinner sig svensk sågverksindustri i den värsta situationen på fyrtio år. Huvudsyftet med examensarbetet var att jämföra olika logistiklösningar för att på ett kostnadseffektivt sätt transportera frigjorda grantimmervolymer i samband med nedläggningen av Vilhelminas sågverk. Problemet löstes i tre faser: ? Kalkyler uppdaterades och skapades för de ingående kostnadsparametrar som behövdes för att räkna ut hanterings- och transportkostnad av skogsråvaran från främst Vilhelminatrakten.

Pellets produceras av sågspån som är en restprodukt från sågverk. Tillverkningen av pellets är en energiintensiv process. Mest energi används för att torka det fuktiga sågspånet från ca 50 till ca 11 % fukthalt. Torkningen är inledningsvis effektiv men vid torkning av sågspån under 20 % fukthalt minskar torkningens energieffektivitet. Efter att det torkade sågspånet malts i en kvarn konditioneras det med överhettad ånga innan det pressas till pellets.

The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting Timber. The method was tested in a case study at a district. The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.

This study is commissioned by the Swedish University of Agricultural Science (SLU - Department of Forest Resource Management) in coorporation with Sveaskog and Vilhelmina Norra Sami reindeer herding community. The purpose of this study is to analyse movement patterns and habitat use of reindeers during two winter seasons (2005/2006 and 2006/2007) in areas affected by forestry activities such as clearcutting. This study examines the possibilities of analysing information from Reindeer husbandry plans and forest variable data from kNN and SMD, in relation to GPS collar points from reindeers by using Geographical Information System (GIS). Lack of knowledge and understanding between the reindeer industry and the Timber industry has often led to heated debates. The possibilities of using this type of technique are very interesting and could increase knowledge concerning land-use issues to different resource users. The main results from analyses comparing SMD, kNN, data about clearcuts, and GPS collar points from reindeers indicates that clearcut areas, younger forest, coniferous forest on lichen-dominated areas and areas dominated by pine was preferred by reindeers during the winter period.

SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies.During the years 1996-2005 first commercial thinning of lodgepole pine at SCA took place.The goal of the hereby presented study was to investigate the growth and stability in thosefirstly-thinned lodgepole pine stands a few years after thinning. Furthermore, the objectivewas to investigate the relationship between stand stability and different stand parameters.Additionally, lodgepole pine stem quality was estimated.The study is mainly based on the data collected during an inventory project carried out atSCA in 2008. Altogether 91 lodgepole pine stands in northern Sweden were measured afterthe first thinning.

Sedan marknaden för lantbruksfastigheter avreglerades i början av 1990-talet så har priserna på skogsmark ökat kraftigt. Då priset på timmer och massaved inte ökat i samma takt råder år 2014 en situation där priset på en skogsfastighet är högre än dess avkastningsvärde. Detta gör frågor som rör skogsägarnas värdering inför köp av skogsmark högintressant. Tidigare studier inom samma område har haft som mål att fastställa vilka faktorer som har en inverkan på fastighetspriset. Bonitet och produktiv skogsareal är två grundläggande faktorer som beskriver fastighetens karaktär. Ändå har det ibland visat sig svårt att hitta ett statistiskt samband mellan dem och fastighetspriset.

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.
