Reopening schools is always a challenge, made even more difficult this year by the pandemic. Now schools must also consider how to create a safe environment for both students and staff to use. SEEM Middle School was looking to do just that. SEEM is a collaborative school, meaning their students come from several communities because they were not making enough progress in either their previous placement or home district. With such a variety of students, SEEM is considered high needs and thus is staying open as their students benefit from in-person classes.

The dental industry is currently one of the most at-risk industries during the COVID-19 pandemic. Since dental procedures create significant aerosolized particles, the risk for contracting COVID-19 or other airborne diseases is high, and thus many dentists are looking for ways to make their offices safer for patients and staff. DCAA Dental was searching for a simple, accurate, economical, and highly visible method to visualize whether or not a room was safely negatively pressurized.

To effectively manage energy consumption and develop plans for cost savings, it is crucial to understand your electric bill. Once you understand your electric bill, you can leverage that information to make changes to electrical consumption and ultimately save money.

Monitoring air quality is crucial for maintaining the safety of the population during wildfires. Although a proper air quality measurement requires several calculations, monitoring one of the parameters contributing to air quality can be a useful indicator. One such parameter is PM_2.5.

Power meters are used in a wide variety of applications to measure electricity use on a more granular level than the main utility meter. Power meters, or submeters as they can sometimes be referred to as, can tell you where, how, and how much electricity is being used in the building.

I²C stands for an integer-integrated circuit. This is a commonly used communication protocol that is flexible enough to be used for a wide variety of applications. Specifically, I²C is a serial communication method with bi-directional two-wire communication. Any sensors and secondary devices only communicate when asked to by the primary.

Revenue grade power meters are defined in the American National Standards Institute (ANSI) standard C12.20-2010 Class 0.2. The intention of such a standard is to establish the requirements for power meters so the meters in question accurately and reliably provide monitoring. This ANSI standard has 3 accuracy classes: 0.1, 0.2, and 0.5. These classes correspond to accuracy at full load and include CTs.

In the wake of the coronavirus, it is imperative for hospitals to be prepared for future outbreaks of infectious diseases. For these situations, the safest method for treating patients is isolation rooms. The safety and effectiveness of such rooms is contingent upon proper control of the room's differential pressure.

Power meters measure utilities like electric, gas, or water to increase building performance. With a power meter, users can get granular data on the use of energy of a building. Such granularity can reveal any equipment or systems adding to energy waste. Submeters can be used in any type of building, from manufacturing to apartments. Meters make it easy to visualize and optimize energy usage.

During a disease outbreak, there are several risks dentists encounter. One serious risk is contracting an illness from aerosol particles created during a procedure. Aerosols are splatters, mists, or droplets in the air, and can include saliva, blood, and plaque. Three main sources of airborne contamination in dental offices are dental instrumentation, saliva and respiratory sources, and the operation site. Aerosol particles can be generated with:
