How many maximum credits are available for IAQ Acoustic Performance in Healthcare projects?

In healthcare projects, the Indoor Air Quality (IAQ) Acoustic Performance credit allows for a maximum of two credits. This credit focuses on reducing noise in healthcare environments to enhance patient comfort and privacy, which is particularly crucial in settings where healing and rest are essential.

Achieving these credits involves demonstrating compliance with specific acoustic requirements that align with best practices for healthcare facilities. These acoustic standards address elements like sound transmission and impact noise, contributing to an environment that supports better health outcomes. Consequently, the structure of this credit system is designed to encourage projects to exceed standard requirements, thereby promoting overall acoustic quality in healthcare settings.

The other options suggest higher numbers of available credits, which isn't aligned with the established guidelines for IAQ Acoustic Performance in the LEED v4 rating system for healthcare projects.
