Most local regulations for indoor air quality are designed around ASHRAE Standard 62. This standard specifies the minimum amount of outdoor air flow into an occupied space to be between 15 to 60 CFM per person, but more commonly building regulations require 15 to 20 CFM per person. Besides actually measuring the air flow, ASHRAE also defines indoor air quality using the concentration of carbon dioxide gas in the air. Carbon dioxide is recommended to be less than 1000 PPM. When sizing the air handling unit for a building, engineers will make the design exceed the maximum occupancy in the building or space to ensure that they will always be able to meet the minimum air requirements. In most cases, buildings or mix used spaces rarely are occupied at these maximum levels, thus the amount of conditioned air supplied is usually much greater than what is required. As building owners aim to reduce energy costs and operate buildings more efficiently, wasted energy of conditioning unneeded outside air has been a good place to start.

Energy Savings from On-Demand Ventilation
There are several different component parts that go into a dust collector for monitoring and control purposes. In this article, we are going to focus on timer boards. We will be comparing and contrasting a few of our timer boards, as well as discussing how we could help you to better protect your equipment in the most cost-effective manner. 
In the world of metrology, measurement uncertainty and its level of impact on calibration plays a huge role in decisions about what products to purchase, along with who to receive calibration services from. Minimizing measurement uncertainty is key for anyone making critical measurements, but many may be confused about what measurement uncertainty is and how to determine the significance of an assigned value.
