Are you tired of stuffy buildings and stale air? Discover the secrets to creating healthy indoor environments.

Welcome to "HVAC Hacks," a comprehensive course series packed with essential tips, industry standards, and rules of thumb to simplify your HVAC design process. Explore the range of course modules tailored to meet your specific needs.

Module 4, "Breathe Easy with Proper Ventilation and Indoor Air Quality," focuses on the crucial role of ventilation in maintaining good indoor air quality (IAQ). You'll explore ventilation strategies to prevent the spread of airborne diseases and promote healthy buildings. Industrial ventilation prioritizes heat and contaminant control through dilution ventilation and local exhaust ventilation.

In this 6-hour course, you'll receive a thorough overview of ventilation principles, covering design, equipment selection, operation, and maintenance. Practical tips and useful rules of thumb are provided to aid in making informed decisions.

Regardless of whether you work in building design, HVAC systems, or you are simply looking to enhance your understanding of indoor air quality and comfort, this course is suitable for individuals from all backgrounds. No prior knowledge of HVAC systems is necessary.
