Sammanställning och utvärdering av små avloppsanläggningar utifrån tillförlitligheten hos angivna reningsgrader
The private sewage systems in Sweden releases around 600 tons of phosphorus per year, compared to about 350 tons from municipal sewage treatment plants, and they account for approximately 21% of the total anthropogenic discharge of phosphorus into Swedish waters. About 40% of Sweden's nearly 1 million private sewage systems are inferior with respect to emissions to surface and groundwater. The technology of small sewage plants is under development and knowledge of treatment effects for different solutions is poorly consolidated. Municipal authorities lack resources to keep up with the technologic development and assess the reliability of the treatment performances that suppliers report for their products. The thesis aims to conduct a market review and evaluation of wholly or partially Prefabricated small sewage plants, to make it easier for municipalities and property owners to assess different technical solutions. The goal is a compilation of the products on the market, evaluated on the basis of the reliability of specified degrees of reduction.Information on sampling procedures and test results were collected through a questionnaire to all active suppliers and the responses were then used to classify the products.
Erfarenheter från flerbostadshus som passivhus : En handflata och sex värmeljus
All new households were to be constructed with "near zero energy house standards" (NZE-house) by the year of 2020. The ambition to construct energy-efficient buildings had to increase rapidly in the spring of 2013.The purpose of this report was to increase the interest for building contractors to construct apartment buildings with passive house standards. By locating and evaluating experiences from an existing passive house a case study including interviews, field visits and document analysis was made. Research of literature regarding other passive houses in Sweden also helped to answer the following questions:- What positive and negative experiences have the study of the passive house meant to the involved stakeholders and residents?- What improvements can be made based on identified experiences?- How can an apartment building be designed as a passive house based on possible improvements?By collecting good and bad experiences, as well as improvements and potential design proposals, a diagram was created designed as a tool for developers when constructing apartment buildings with passive house standards.
Prefabricerade Passivhus
European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket?s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report?s issues, including Anebyhus?s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements.
Logistikcentra
International Marine Group, IMG AB, was established in year 2000, and became the parent company of the three sister companies, Momec AB, Isolamin AB and Premec AB. The IMG ? group supplies complete marine/offshore interior accommodation and tailor-made system supplies to the Building/Industrial sector. With a starting point to develop IMG AB?s logistic and distribution the company has decided to survey the present logistic at their subsidiaries, mainly concentrated on the goods for delivery.
Toleransproblem vid produktion och montering av prefabricerade betongelement
The idea with constructions made out of Prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.
