Fuktstudie av en klimatvind på ett äldre småhus : En utredning av effekterna på vindsklimatet vid utvändig takisolering

Laiti, Pär-Henrik January 2017 (has links)
Mögelpåväxt orsakat av fuktproblem är vanligt förekommande på kallvindar i det svenska småhusbeståndet. Enligt en rapport från Boverket har var femte småhus en fuktskada på vinden orsakad av hög relativ fuktighet. Statistik från samma rapport visar att äldre hus med självdragsventilation är drabbade i större utsträckning. Luftläckage av fuktig inomhusluft till vind uppges vara en orsak bakom förhöjd luftfuktighet. Äldre hus är oftast inte lika lufttäta som moderna vilket gör dessa kallvindar mer utsatta. Att tilläggsisolera yttertaket utifrån har visat sig vara en åtgärd som sänker den relativa fuktigheten på kallvindar. Detta brukar kallas för att bygga om kallvinden till en klimatvind.   Denna studie baserar sig på en klimatvind på ett äldre småhus beläget i Skellefteå kommun. Den tidigare kallvinden var drabbad av fuktskador och byggdes därför om till en klimatvind 2014. Sedan dess har ingen utvärdering gjorts om detta är tillräckligt för att fuktsäkra vinden. Syftet med denna studie är därför att ta reda på om klimatvinden på detta hus är fuktsäker till följd av ombyggnaden. Resultatet kommer att användas som ett underlag för att besluta om fler åtgärder är nödvändiga för att fuktsäkra vinden.   För att bedöma fuktsäkerheten har mätningar av temperatur och relativ fuktighet på klimatvinden utförts. Under samma period utfördes även likadana mätningar på en traditionellt uppbyggd kallvind belägen 150 meter från klimatvinden. Genom att jämföra mätresultat mellan dessa vindar kan slutsatser om den utvändiga isoleringens effekt på vindsklimatet göras.   Resultatet av klimatmätningarna visar att den relativa fuktigheten på klimatvinden har legat långt under kritisk nivå för mögeltillväxt. Under samma mätperiod har relativ fuktighet på referensvinden varit i närheten av kritiska nivåer. Klimatvinden har i jämförelse med referensvinden ett varmare och torrare klimat och påverkas inte i lika stor utsträckning av svängningarna i utomhusklimatet. Slutsatsen är att klimatvinden anses vara fuktsäker under mätperioden. Rekommendationen är att fortsätta med klimatmätningar under en helårsperiod för att kunna bedöma fuktsäkerheten ur ett helårsperspektiv. / Mold growth caused by moisture are common in cold attics in small houses in Sweden. According to a report from the National Board of Housing - Boverket, a fifth of all attics in small houses in sweden has moisture problems caused by increased levels of relative humidity. Statistics from the same report show that older houses with natural draft ventilation are affected to a greater extent. Air leakage of damp indoor air into the attic space is said to be one cause of increased humidity. The construction of older houses are usually not as airtight compared to modern houses. This makes the attics in old houses more vulnerable to this problem. Additionally insulation with eps insulation at the outside of the roof has been shown to reduce the relative humidity in cold attics. This report refers to attics with this type of construction as a ”climate attic”   This study is based on a climate attic of a older house located in Skellefteå municipality. The former cold attic had mold problems caused by moisture and was therefore converted to a climate attic in 2014. Since then, no evaluation has been made of the moisture saftey in this climate attic. The purpose of this study is therefore to find out if the climate attic in this house is moisture safe due to the conversion. The results will be used to determining whether more actions are necessary to make the attic moisture safe.   In order to evaluate the moisture safety in the climate attic, measurements of temperature and relative humidity has been made. During the same period measurements were made in a traditionally cold attic. By comparing measurement results between those attics conclusions of the effect from the external isolation can be made. The results from the measurements made in the climate attic shows that the relative humidity has been far below critical levels for mold growth. During the same period the relative humidity in the traditional cold attic has been close to critical levels. In comparison with the traditionally cold attic, the climate attic has a warmer and drier climate and is not affected to the same extent by the fluctuations in the outdoor climate. The conclusion is that the climate attic are considered to be moistureproof during the time measurement was made. The recommendation is to continue with climate measurements over a full-year period to assess moisture safety from a full-year perspective. / <p>Kull H14</p>

Novostavba bytového domu / Newly built Apartment house

Pícha, Libor January 2018 (has links)
Diploma thesis „ Newly bulit apartment house“ deals with a proposal of block of flats in Veselí nad Lužnicí. The block of flats has got four storeys with no celler, and is in a rectangle shape. It is independently built house on a flat terrain. Bricked construction consists of ceramic constructuion blocks Heluz and reinforced concrete ceilings. The building is based on foundation belts and is roofed by a single-coat flat roof. There are 29 housing units designed in the building.

Horský hotel / Mountain hotel

Jurčo, Pavel January 2013 (has links)
The Master's thesis dealt with the project new construction hotel in the village of Kvilda, district Prachtice. Mountain object is used for accommodation and meal serving of guests and its accommodation capacity is 50 reviews. The building is partly basement with three floors. The support system is made up in the basement of formwork blocks and in the overhead floors ceramic blocks, which are supplemented by insulation system Porotherm with Styrofoam. Object is an irregular floor plan and is covered with a single layer flat roof. In addition to fire safety, the work addresses the project documentation as well as an assessment of the proposal of concrete constructions and solves the heat heating object too.
