How can hospitals reduce energy costs?

Like most businesses, hospital administrations constantly look for ways to improve their bottom line. One of the most effective ways a hospital facility manager can help is by lowering building operating costs and running their building more efficiently. But because healthcare facilities are extremely sophisticated and specialized buildings, this task is often easier said than done.

What do electrical contractors look for in a power meter?

User-side energy submetering is becoming increasingly popular in new commercial construction and renovation projects alike. The latest advanced LEED certification requires operator-owned submeters to be installed in high consumption areas and facilitate continuous tracking of total consumption for an entire structure.

How to Select a Power Meter

What Are You Monitoring?

One critical consideration when searching for a proper power meter is to determine what you're measuring. Is the monitored load signal-phase, split-phase or three-phase? What voltage/current ranges are going to be monitored? 

If you're interested in a power meter for residential or light commercial applications, then typically a single or split-phase meter would be the best cho

What is Total Harmonic Distortion?

Imagine a tone being played by two musical instruments -  let’s say middle-C (261.63 Hz). While the pitch played on a piano may be the same as on an electric guitar, its timbre is very different. The sound wave generated from a piano or a simple synthesizer is relatively simple and clean, but the sound wave coming from an electric guitar is often very distorted for effect and contains natural harmonic overtones.

What is the difference between Rogowski Coils and conventional CTs?

Understanding specific job requirements, such as performance, installation, amperage load and environmental factors is critical to selecting the proper current transformer for an application. Conventional current transformers (CTs) do come with their limitations as they are difficult to install and are lacking in performance and measurement range. Rogowski coils have significant advantages with regards to installation, cost and performance.

What is Submetering?

Submetering is the installation of metering devices with the ability to measure energy usage after the primary utility meter.  Submetering offers the ability to monitor energy usage for individual tenants, departments, pieces of equipment or other loads individually to account for their actual energy usage.  With submetering, a clear and accurate picture of how and when energy is being consumed inside a facility is created.

Is Building Automation and the Internet of Things Related?

The Internet of Things (IoT) is changing the way people run their homes. More and more devices are becoming available to consumers that allow them to automate their thermostats and regulate their power consumption, often-times controlling these systems from the phone in their pocket. Products like the Nest thermostat and the Sense home energy monitor provide homeowners convenient tools that also help save utility costs.

Building Automation

In commercial and industrial buildings, there are similar (albeit far more robust) systems and protocols used for the same purposes called building automation. Building automation is the automatic and centralized control of a building’s heating, ventilation, air conditioning, security, electrical, and other systems through a Building Automation System (BAS).

What is peak demand?

Looking at your electric bill can be a daunting task. There are many factors that can affect your bill’s total — factors that are only amplified in large commercial and industrial sites.

One such consideration is peak demand. Peak demand is the largest instance of power usage in a given time frame, typically a rolling fifteen minute window. Measured in kilowatts (kW), peak demand is different than consumption. Total consumption  is measured in kilowatt hours (kWh) over a given period of time (e.g. monthly, quarterly, etc.).

What is power factor?

The power flowing through an alternating current (AC) load isn’t always pulling its full weight. Every AC circuit has some degree of non-working power as part of its total power reading and this can affect the amount of power a system is truly drawing.
