1. Back to basics: How to design medium-voltage distribution systems

When designing a medium-voltage electrical distribution system, the end user’s safety, system reliability and equipment maintainability are key components for the designer to consider.

2. Best practices: Ensuring NFPA 20 compliance with diesel-driven fire pumps

To meet NFPA 20, existing buildings must upgrade fire pumps. Learn how.

3. Your questions answered: How to design electric vehicle charging stations

Are your clients asking for electric vehicle charging stations? Learn more from these answered questions

4. Definitions, codes and standards for medium-voltage systems

Understand the definitions related to medium-voltage (MV) systems, as well as other voltages

5. Hydronic heating systems: How can you save by lowering the water temperature?

Lowering the temperature of heating hot water systems is a key step toward decreasing energy used to heat buildings, and toward decarbonization and electrification.

6. Germicidal UV lights could be producing indoor air pollutants

While useful for killing pathogens such as COVID-19, the lights may cause unwanted chemical reactions and should be used with ventilation, according to an MIT study.

7. How to prevent shock and arc flash hazards in electrical systems

This article serves as a guide to understanding electrical hazards and establishing electrically safe work environments.

8. How to use best practices to illuminate a NICU

New guidelines address the complex lighting needs of newborn infants, birthing women, family members and hospital staff.

9. Important considerations from the history of modern building control systems

Building controls technologies, open communication protocols and networked internet protocol evolved to create a relatively easy means to integrate multiple control systems.

10. Back to basics: Control systems, drives and motors

This presentation will discuss control diagrams, coordination with trades and power outage concerns. Applications of dampers, valves, contactors and sensors will also be discussed.
