De-Mystifying ASHRAE Standard 170 - Myths VS Truths on Healthcare Ventilation

Описание: rehearsal of a presentation for a national conference in 2025.

MYTH #1: ASHRAE 170’s ventilation requirements are based on evidence related to disease transmission, infection control, and hospital air quality.
MYTH #2: The air change rates specified in ASHRAE 170 are necessary for infection control
MYTH #3: The ventilation rates in ASHRAE 170 are necessary to ensure optimal indoor air quality.
MYTH #4: The ventilation rates in ASHRAE 170 represent a balance between infection control, air quality, cost, and energy efficiency.
