Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme

In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.

Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början

This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.

Cassava as an additive in biomass fuel pellet production :

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

Teknik för egen foderberedning :

There is an uncertainty in the market for grain forcing the meat/milk producers to review alternative feeds to a larger extent, in order to get control over the feed costs. This has led to that the meat/milk producers need to have a good knowledge regarding how the different feeds influences the animals and which technical equipment to use for handling. For those that produce their own feedmix, there is a need to put interest in new crops and their characteristics to be able to get the knowledge of what is required for their own production. It is beneficial to keep an open dialogue with advisors to be updated in new crops and new technology for feeding. When mixing feed at farm level, the legislation is not very clear since it the target group is large scale mixing plants. We have brought up the most important rules and regulations from the EU parliament Council as well as the ones from the Swedish Board of Agriculture (SJV), regarding feed mixing on farm and factory level. We have studied beans and pea at two different moisture levels, in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill.

Passivhus med prefabelement : En jämförelse mellan en platstillverkad konstruktion och prefabelement från Masonite Lättelement AB

This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..

Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Biomass losses during short-term storage of bark and recovered wood

Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).

Upprättande av mall för fuktsäkerhetsbeskrivning : Genom granskning av projekt ur fuktsäkerhetssynpunkt

During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.
