    Lipton - Det smarta trähuset: Energieffektivisering av Dalahus lägenhetskomplex i trä2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Earth's climate is affecting all countries and Sweden is no exception. With agrowing global environmental problem everyone needs to contribute to change.The project's contribution to the environment is to show how energyconsumption of a multi-family apartment block can be reduced. By calculatingUm for the house Lipton's current building envelope and identify the parts whereimprovements could be made, and compile the elements of design which aremost promising for improving the building envelope. Technical measures witch isnot directly related to the building envelope, such as demand controlledventilation, electrically efficient fans and other energy-smart solutions will beutilized to reduce Lipton specific energy consumption.Buildings lose heat through the building envelope but by harnessing the sun'senergy, think carefully about the building's placement, increase insulationthickness and use smart ventilation solutions, the project aims to reduce thehouse Liptons specific energy consumption to at least half of Boverkets energydemands in 2014 for new buildings in climate zone 2 which is set to110 kWh/m2 year.To calculate the specific energy consumption in use phase, a simple calculationprogram, TMF-Energy 2.3, will be used. In the project, the heating system,water/sewer and use of household energy is not to be included.The original design of the house Lipton has a specific energy consumption of56.9 kWh/m2 year which is relatively low and almost half of Boverkets energyrequirementsThe energy consumption of Lipton will be decreased by:• Improving Um for Lipton's building envelope.• Using a double-shell technology.Högskolan Dalarna• Plan where the house is located for favorable outer conditions• Using demand-controlled ventilation with energy efficient fans

    Tillbyggnad av miljonprogramsvilla: Olika tillbyggnader anpassade för miljonprogramsvillor2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Many villas built under the "miljonprogram" is in need of extension due to being too narrow in addition of being worn out. For this reason, many families chose to move out of these villas in favor of buying a bigger and more modern house. This means that the "miljonprogram" villas are in need of refurbishment to not lose too much value and popularity. Refurbishment of these villas can be done in many ways. One being a extension of the house, changing the truss or just a flat overall refurbishment. The method varies depending on the build of the house, as most if not all houses are constucted in different ways. A purpose of this report is to present a variety of how these villas can be rebuilt in favor of higher standards and a bigger living area. Various proposals will be presented where each development is made in different ways. Another purpose of the report is to compile the material costs for the various additions.

    This is done in order to gain an economic perception of the various additions and which add-on option is most economically sustainable

    The test object used in the report is stationed in Falun. The building is a typical miljonprograms villa with a pitched roof. The façade material for the villa consists of non-bearing façade pointers. The various additions to the project are based on the test object's original drawings. The new blueprints for the villa is drawn in the architectureprogram Revit.

    In the results section, various supplementary proposals are presented and finally an economic comparison is made.

    This is made to get an economic view of the various additions proposed in this report. Where the prices are compared in SEK per square meter.

    The discussion section discusses, among other things, the various additions suggested earlier.

    How the surfaces of the test object are trying to be preserved and the though process behind the new additions.

    Finally, economic aspects are discussed in the results part of the report. Four different conclusions are included in the report.

    One conclusion is that a mansard chair creates many new surfaces upstairs, and that it is also economically advantageous from a material cost perspective.

    Tekniskt samråd: Studie av likvärdighet i utförandet2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A new planning- and building act was applied the 2nd may 2011. The intention was to simplify the planning- and building process as the control of constructing where tightened. In the new act there has been introduced a deadline for the building permits of ten weeks. To be allowed to begin the constructing you will need a starting clearance. The clearance is preceded by a technical consultation.

    The purpose of this study was to survey if the technical consultation is performed equivalent between different municipalities in the county of Dalarna. Other purposes was:

     To create a basis for improvement regarding the technical consultation.

     Examine how to facilitate or improve the consultation.

     Illustrate why the technical consultation is so important in the building process.

     Clarify the differences in the new and the old act regarding the consultation.

    To understand what a technical consultation is and how it should be performed the work began with a literature study. A literature study was also performed to pick a method for the work. These studies resulted in a method based on the semi-structured interview form. A number of interviews were conducted in five building committees in Dalarnas County. To study the technical consultation in practice a visit during a consultation were conducted at Mora – Orsa and Falun municipalities.

    This thesis was delimited to examining how technical consultation is performed and works in various building committees in Dalarnas county. The work was delimited to only process opinions from building inspectors and a control manager.

    The results have been compiled and are reported in the results chapter. All respondents in this thesis have the opinion that complete documentation is essential to carry out a technical consultation. The developer should be well-informed and familiar with the project and an experienced developer could simplify the building process. A technical consultation is of great importance to ensure that the society’s conditions upholds. It is particularly important to hold a consultation when the developer is inexperienced.
