Öhler, SvenSvenÖhlerKoehler, MarkMarkKoehler2025-08-292025-08-292025https://publica.fraunhofer.de/handle/publica/49472110.71568/dasdaga2025.607Sustainability in building acoustics is increasingly important in the architectural and construction industries, addressing the need for environmentally responsible design that enhances human comfort and ecological balance. As urbanization accelerates, managing noise pollution becomes crucial, leading to adverse health effects and reduced quality of life. This article explores the relationship between sustainability, acoustic performance, and costs in actual building practice. The study examines traditional acoustic design practices that often overlook the environmental impact of materials. By using sustainable materials, such as recycled resources, architects can minimize the ecological footprint while ensuring effective noise reduction. Innovative technologies like green facades and rapidly renewable materials provide solutions for enhancing acoustic comfort without compromising sustainability. Additionally, the article discusses building regulations that promote sustainable acoustics, encouraging stakeholders to prioritize noise management in their projects. It also questions why sustainable building systems are rarely used in modern construction despite growing social demand. The findings highlight the necessity of a holistic approach that considers both affordable acoustic and environmental performance. A commitment to sustainability in building acoustics contributes to healthier living environments and supports broader goals of reducing carbon emissions and conserving resources.enconference paper
