How is Stability Related to ASHRAE 62.1 Standards?

Jonathon Jachura — Wed, 27 Jan 2021 15:46:06 +0000

ASHRAE 62.1 Standard for Ventilation for Acceptable Indoor Air Quality provides recommendations for minimum ventilation rates and other parameters to ensure good indoor air quality (IAQ). Keeping the IAQ at a safe level will help to minimize any adverse health effects caused by air quality factors. The 62.1 standard is intended for both new building …

Moisture Control for Indoor Air Quality

Andrew Goldschmidt — Wed, 05 Aug 2020 15:40:01 +0000

As buildings continue to become more and more energy efficient, we continue to see updates and recommendations to building designs. For example, ASHRAE recently published an update to Standard 62.1 Ventilation for Acceptable Indoor Air Quality that covers changes to how we monitor and control humidity in occupied spaces. To better understand why these humidity …

Characteristics of Thermal Anemometers & Why They’re Well-Suited for Low Flow Applications

Andrew Goldschmidt — Wed, 08 Jul 2020 12:38:42 +0000

There are two common ways to measure air velocity: by using pressure-based instrumentation or by using temperature-based instrumentation. Before we discuss the different technologies available for measuring velocity pressure, it is important to understand the basics of air velocity. Air velocity is the area of air movement measured in distance traveled relative to time elapsed. …
