Bullerskydds integrering : en fallstudie i Borås / Integration of noiseprotection : a case study in Borås

Sandén, Gustav, Hedenström, Jonas January 2012 (has links)
En av de största miljöstörningarna i Sverige är trafikbuller. Över 1,4 miljoner människor uppskattas vara exponerade för buller överskridande 55 dB. Buller är ett hälsoproblem, inte livshotande men påverkar både hälsa och livskvalité. Buller kan till exempel störa sömn, skada hörsel, skapa koncentrationssvårigheter och vid exponering under lång tid, leda till problem med hjärt- och kärlsystem. Syftet med detta arbete är att utreda bullerskydd som kan integreras i fasad samt vidare utreda hur dessa i så fall kan användas vid utformningen av en byggnad. Rapporten är utredande och utgår från två frågeställningar.1-vilka typer av bullerskydd kan lämpa sig för integrering i byggnadens yttre skikt?2-hur kan bullerskydd integreras som en del i byggnadens utformning och design? Frågeställningarna i denna rapport är besvarade med hjälp av litteraturstudie, analys och skissarbete. Litteraturstudien innehåller information angående olika typer av bullerskydd. Exempel på sådana skydd är bullerskärmar, vegetation och loftgång. Studier av referensobjekt samt detaljplan är de delar som utgjort analysmomentet. Utifrån dessa två moment har sedan ett skissarbete genomförts där lämpliga lösningar integrerats samt illustreras i form av handskisser samt 3D modeller. Fristående bullerskydd t.ex. bullerskärmar kräver ofta mycket plats och kan vara svåra att integrera i ett tätbebyggt område. För att motverka buller är det av stor vikt att redan i planeringsskedet ta hänsyn till buller och möjliggöra för en god ljudmiljö. Hänsyn till klimat och exponeringsgrad bör tas vid val av bullerskydd, detta då vissa förhållanden inte är gynnsamma för alla typer av skydd. De bullerskydd vi utrett har utvärderats angående dess möjlighet till integrering och lämplighet för fastigheten som arbetet är grundat på. Efter utvärdering valdes loftgång med glasfasad, grönt tak samt val av en utformning på byggnaden som gav goda förutsättningar till tyst sida. / One of the major environmental disturbances in Sweden is traffic noise, over 1.4 million people are estimated to be exposed to noise exceeding 55 dB. Noise is a health issue, not life threatening but it affects both health and the quality of life. Noise can for example disturb sleep, cause hearing problems, create difficulty in concentration and longtime exposure can lead to problems with the cardiovascularsystem. The purpose of this rapport is to investigate how noise protection can be integrated in the facade and the design of a building. The report is based on two questions.1-what types of noise protection may be suitable for integration into the building's outer layer?2-how can noise protection be integrated as part of the building’s design? The questions included in this report are answered with the help of a literature study, analysis, and sketching. The Literature study contains information on the different types of noise protection. Examples of such protection is noise barriers, vegetation and exterior corridors. Studies of reference objects and the detail plan are the parts that formed the analysis. Based on these two elements, sketches with appropriate solutions were illustrated both in form of hand sketches and 3D models. Noise protection such as noise barriers often require a lot of space and can be difficult to integrate into an urban area. To counteract noise, it is important that already in the planning stage consider noise problems. This to enable and provide a good acoustic environment. Consideration of climate and level of exposure should always be taken when selecting noise protection, this when certain conditions are not favorable for all kinds of protection. The noise protection we investigated was evaluated regarding its ability to be integrated and its suitability for the property to which the work is based on. Following evaluation, exterior corridors with a glass façade, green roof and a design of the building which provides good opportunities for a “tyst sida” were chosen.

BULLERPROBLEMATIK I BOSTADSOMRÅDE VID NÄRLIGGANDE MOTORVÄG : Södra Källtorp i Västerås

Dusky, Karez, Ahmed, Dania January 2022 (has links)
Purpose: This degree project has investigated the problems Södra Källtorp has with noise due to the nearby highway E18. The purpose of this work is to investigate whether Södra Källtorp meets the guideline values and also whether the implemented noise protection measures in the neighbourhood have caused a change regarding the noise level. Method: The method for carrying out this degree project consisted of a literature study and a case study. The case study was carried out through own measurements and calculations. Four measuring points were chosen. The first two are located in Södra Källtorp and are covered by the noise protection, while the last two are not covered by any noise protection and are located in Råby. Based on the measurement results, the daily equivalent sound level was calculated based on the annual average daily traffic for each measurement point. In addition, interviews were held in order to get a picture of the noise experience among the residents in the neighbourhood. Results: According to the measurement results, the daily equivalent sound level was 55 dBA and the daily maximum sound level 61 dBA for measuring point M1. For measuring point M2, the daily equivalent sound level was 46 dBA while the daily maximum sound level was 53 dBA. Measuring point U1 had a higher noise level than measuring point M1 and measuring point U2 had a higher noise level than measuring point M2. Conclusions: Conclusions that can be drawn are that the noise protection measures have made a change regarding the noise level in Södra Källtorp and that the noise levels in Södra Källtorp do not exceed the guideline values. However, most noise levels that occur in the neighbourhood are not approved according to WHO. More noise protection measures may need to be taken in the future in order to meet WHO’s recommendations.
