Acoustics is a critical component in providing a comfortable listening environment for users and is recognized by several building rating systems for sustainability and health including LEED, WELL, Fitwel, and Passive House. We will overview of acoustic principles and various ways in which sustainable design can be applied to acoustics to extend green design concepts. We will discuss the ABCs of architectural acoustics and the importance of proper acoustic design to the comfort and wellness of occupants across different types of building uses. We will discuss design strategies to help achieve the acoustics requirements of various building rating systems throughout the design and construction process. We will discuss synergies of acoustical design with other green building strategies – such as environmentally friendly materials, smarter use of energy, water and material resources and improved indoor environmental conditions – and potential tradeoffs.
