ZEnA (Z3 Controls Energy Analytics) is an interactive web -based energy analytics and business intelligence tool.

Data from NetMeters or other sources such as Utility Interval Meters or other sub-meters, can be processed and displayed in a variety of colourful and intuitive formats that provide insight into patterns and trends.


ZEnA Applications

  • General tool for energy management in industrial and commercial facilities
  • Measurement and Verification (M&V)
  • Monitoring and Targeting (M&T) reporting
  • Energy auditing
  • Measuring true building performance
  • Business case analysis of proposed conservation projects


ZEnA Key Differentiators

  • Data integration

Incorporate live data from NetMeters and online weather feeds

No need to hand massage files

  • High productivity

Simple automated workflow for fast results

Interactive and intuitive

  • High quality results

Weather/production normalization

  • Data control and ownership

Data is completely controlled by the customer

  • Web-based

No need to install and maintain software

Always the latest version

  • Embedded


Scenario Comparison

  • Flexible scenario-based filtering capabilities of ZEnA allow true A-B comparisons such as:


Year over year, quarter over quarter etc.

Weekend versus weekday

Any custom time ranges

  • Key performance indicators calculated and compared, such as:

Base/average/peak load, duty cycle

Energy per sq. ft.

Max, min, average daily energy


Load/Demand Profiles

  • Load profile displays aggregate statistical representation of how energy demand varies over the course of days or weeks
  • Load profiles are displayed for each scenario and includes:

Maximum/minimum energy demand by hour

Average energy demand by hour

Standard deviation band shows how tightly distributed the aggregate data is

  • Load profiles are useful to determine the daily/weekly cycle of a facility. For example, startup/shutdown times, peak hours, and overall load shape


Trend Charts

  • Plot the trend and linear regression for many useful variables including: base, peak, average, standard deviation, duty cycle
  • The trend reports allow key parameters to be visualized over time such as:

Peak demand, average demand, base load

Duty cycle, standard deviation

Daily, weekly, monthly yearly energy

  • Trend charts include a linear fit trendline that help determine if parameters are increasing or decreasing over time.


Energy Heat Map

  • Colour “Heat Map” display

Intuitive colour-coded display of energy over time

Easily spot patterns and anomalies

  • A visual heat gradient colour coding that is applied to the energy data where blue (the coldest colour) represents minimal energy and bright red represents maximum energy.
  • Layout and colour coding of the heat map make it easy to spot anomalies such as facility shut down (horizontal band of dark blue). Regions of bright red clearly indicate high energy use, green is in between.


Weather Normalization

  • To properly measure and compare the operational efficiency of a facility that is temperature sensitive, it is important to normalize the energy data to a reference or “normal” weather pattern.
  • If energy manager compares year-over-year energy data, the results may be disastrous if the baseline year was particularly cold and/or the post retrofit year was particularly hot.
  • ZEnA incorporates data from automated weather feeds to perform weather normalization.
