Abstract [en]

Noise exposure is a considerable environmental problem. Noise management is of increasing importance to human health and quality of life. Over two million people in Sweden are exposed to traffic noise exceeding 55 dB. The Swedish municipality of Lerum is divided by major transport thoroughfares for both road and rail traffic. In addition to tackling noise pollution, the municipality aims to invest in energy-saving and renewable energy technology in order to cut the emissions of greenhouse gases by 2050. The project will demonstrate innovative noise barriers producing solar energy for distribution to local district heating systems, hence an environmentally sound technology. This will be achieved by installing and evaluating specially adapted solar collectors at a major transport thoroughfare for both road traffic and rail in Lerum, which has been identified as the most suitable location. The noise barrier effect will be evaluated by measurements and a questionnaire on perceived noise annoyance both before and after the barrier has been built. The number of properties and people with noise levels above the guideline value of 55 dB is expected to reduce by 60-90 percent and noise levels are expected to reduce by 5-10 dB. Solar collectors are expected to produce somewhat 250 000 kWh of heat at 75 °C to the district heating per year. Reduction of costs associated with noise of SEK 630 000 - 945 000 per year and an increase in the value of properties of 5% is expected.
