What is the required maximum sound level for vacuum cleaners to meet LEED sustainability criteria?

65 decibels or less
70 decibels or less
75 decibels or less
80 decibels or less

The correct answer is: 70 decibels or less

In the context of LEED certification, particularly for Operations and Maintenance, one of the key aspects of building performance and occupant comfort is indoor environmental quality, which includes acoustic properties. To align with these sustainability criteria, vacuum cleaners should operate at a sound level that minimizes noise pollution and enhances the overall indoor experience for occupants. The requirement for vacuum cleaners to operate at a maximum sound level of 70 decibels or less is based on ensuring that noise levels are kept within a range that is generally perceived as acceptable in most building settings. Operating at this level helps reduce distractions and potential discomfort that excessive noise could cause to building occupants, aligning well with LEED’s aim to promote health and well-being. This choice aligns with established standards for commercial and residential environments, where noise control is essential for maintaining productivity and a positive environment. Adhering to this standard enables building managers and maintenance teams to contribute to a more sustainable and occupant-friendly facility.
