In the quest to create more sustainable and comfortable buildings, researchers have turned their attention to an often-overlooked component of indoor climate control: noise. Kęstutis Miškinis, from the Institute of Architecture and Construction at Kaunas University of Technology in Lithuania, has led a groundbreaking study that could redefine the future of building ventilation systems. The research, published in the journal ‘Buildings’ (which translates to ‘Pastatai’ in Lithuanian), introduces a novel textile diffuser designed to reduce noise while maintaining flexibility, sustainability, and ease of installation.
The ventilation system is a critical element in ensuring indoor climate parameters, but it often comes with an unwelcome side effect: noise. As buildings become more energy-efficient, the demand for effective, low-energy ventilation solutions grows. Textile ventilation systems have emerged as a popular choice, but the increased air movement can lead to higher noise levels, affecting occupant comfort and well-being.
Miškinis and his team set out to address this issue by designing a diffuser that meets stringent noise regulations, is lightweight, flexible, and sustainable. “The aim was to create a diffuser that not only reduces noise but also integrates seamlessly with interior design and is easy to install and maintain,” Miškinis explained. The team developed three types of diffusers, each designed to meet specific criteria: noise reduction, lightweight construction, flexible geometry, aesthetic design, easy installation, and sustainability.
The results were impressive. The diffusers successfully reduced noise levels to below the regulated 45 dBA, making them suitable for use in various indoor environments. The square and rectangular diffusers weighed just 1.7 kg and 2.8 kg, respectively, making them lightweight and easy to handle. Additionally, the diffusers were made from recycled materials, aligning with the growing demand for sustainable building solutions.
The commercial implications of this research are significant. As the energy sector continues to prioritize low-energy buildings, the demand for effective and sustainable ventilation solutions will only increase. Miškinis’s diffuser offers a promising solution that addresses both noise and sustainability concerns, making it an attractive option for architects, builders, and property developers.
The research also highlights the potential for further innovation in the field. As Miškinis noted, “This is just the beginning. There is still much to explore in terms of materials, design, and integration with other building systems.” The development of noise-reducing textile diffusers could pave the way for more advanced and efficient ventilation systems, ultimately enhancing the comfort and sustainability of buildings worldwide.
In conclusion, Miškinis’s research represents a significant step forward in the quest for sustainable and comfortable buildings. By addressing the often-overlooked issue of noise in ventilation systems, the study offers a practical and innovative solution that could shape the future of the energy sector. As the demand for low-energy buildings continues to grow, the need for effective and sustainable ventilation solutions will become increasingly important, and Miškinis’s diffuser is poised to meet that need.
