En jämförande analys av projekterade nybyggnationer i Östra Salabacke, ur ett energi- samt fuktperspektiv
… to consider. This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new …
This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for …
Utvärdering av ByggaF
För att efterleva Regeringens miljöpolitik har Boverket tilldelats ansvaret för miljömålet God bebyggd miljö. Boverket är en myndighet som arbetar för Riksdagens miljömål och skall vid behov förslå åtgärder för miljöarbetets utveckling. I Boverkets Byggregler finns krav som …
Analys med simuleringsprogrammet Wufi 2D
Idag ökar man isoleringen alltmer i takkonstruktion för att spara energi. Ökad mängd isolering minskar temperaturen över takets yttre delar och höjer den relativa fuktigheten där. Dessutom finns risk att fuktigt material byggs in mellan alltmer täta skikt vilket leder till att …
För lager-, industri- och kontorsbyggnader
… in roof structures for industrial buildings has been investigated from a moisture standpoint. The analysis shows that without a functioning vapour barrier the moisture content in the construction increases over time, which leads to increased heating costs. The conclusion of this …
… how to make the basic design of the slab on ground more energy efficiency and moisture proof. The study covers four representative flooring types in the Gavlega?rdarnas million program area in Sa?tra. This study aims to investigate and evaluate proven methods for adding …
… In addition, more pine than spruce was incorrectly planted. Without soil moisture maps, the proportion of improper pine and spruce was 66 % and 34 % respectively, and with soil moisture maps, the proportion of improper pine and spruce was 55 % and 45 % respectively. This shows …
… fibers has shown advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced, which can be advantageous for more sensitive paintings. These lining techniques have been included in several studies where reversibility, minimal intervention …
… storage prospects. In addition, transparent paper can be very sensitive to moisture and reacts by deformation or loss of transparency. Due to the volume of these works and the necessity of treatment, there is a call for simple and efficient conservation methods. A common …
… establishment in the thinner humus layer, such as lower competition, more moisture and higher nutrient concentration. However, the average seedling height was the same for both microhabitats. The deep-burned patches constituted only 0,3% of the reserve area. This means that …
… Sludge from sewage treatment works have a high nitrogen level, high ash and moisture levels and thereby a low heating value. It also contains a lot of mercury. This type of sludge is, unlike the other wastes in this study, homogenous and differs only between sewage treatment …

… is that the wood is knotless and without bark. Even the right amount of moisture in the timber is more important than the "right length". Most companies lacked relevant information from the wooden industry. Among the companies who brought the timber from the timber yard …
… of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in …
