Energy management is a growing practice among companies that operate large buildings, campuses, and other complex facilities. Successful energy management requires detailed information on how energy is being used. However, this valuable information is not available in facilities being actively monitored. For effective energy management, facility engineers need to understand exactly how and where energy is being consumed on their properties.

Why Invest In Tenant Billing?
The goal of any commercial property owner is to attract tenants while also still being profitable. Operating a large building often means having a lot of expenses and other overhead costs, whether they be for maintenance, repairs, utilities, or the multitude of other expenditures any business could incur.

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

How are power meters used in LEED projects?
LEED, the Leadership in Energy and Environmental Design, is the largest driving force behind the increased development of green buildings in the world. One of the most important factors that LEED uses in their certification process is energy consumption and the owner’s ability to track usage and identify potential savings. While most conventional buildings have simple meters provided by the utility company for billing purposes, the advanced standards for LEED certification require more robust and more precise monitoring capability.

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.

What is the difference between NEMA and IP ratings?
In manufacturing, there are two standards used to measure the different grades of electrical enclosures and how resistant they are to the ingress of certain materials. NEMA ratings and IP ratings both define degrees of protection against substances such as water and dust, but use different test methods and parameters to define their enclosure types (NEMA 250 and IEC standard 60529).

How To Measure Velocity And Flow
In HVAC/R applications it is helpful to understand the methods used to determine air velocity. Air velocity (distance traveled per unit of time) is most often expressed in feet per minute (FPM). Multiplying air velocity by the area of a duct allows you to determine the air volume flowing past a point in the duct per unit of time. Volume flow is generally measured in cubic feet per minute (CFM).

Capacitance & Inductive Pressure Sensors
Setra’s capacitive pressure transducers are expertly designed adaptations of a simple, durable and fundamentally stable device...the electrical capacitor. In a typical Setra configuration, a compact housing contains two closely spaced, parallel, electrically isolated metallic surfaces, one of which is essentially a diaphragm capable of slight flexing under pressure.

The Importance of Maintaining Building Humidity
While it is important to maintain proper relative humidity levels in office buildings for worker comfort and productivity, it is also just as important to maintain proper levels in factories, production facilities and art galleries to protect industrial, commercial and artistic products.

Guide for Establishing Relative Humidity Levels in Operating Rooms
Successful surgery depends not only on the performance of medical professionals, but also on the integrity of the environment. Relative humidity is a critical component in maintaining the safety and performance of an operating room (OR).
