•What does Energy Management mean for us?

•It is a range of products able to:

Measure the most important electrical variables like:

Power, Energy, Power factor, Current, Voltage, Frequency,

as well as Gas / Water Consumption

Carry out the control, the supervision of the power supply

and of the loads in various electrical installations

In order to:

▼ Optimize the power consumption

▼ Generate historical files

▼ Save energy and therefore money

Pulse™ EMS Overview

• Pulse™ Connector – Data logger

• Communication Protocols – Modbus & BACnet/IP

• Electrical Energy, Natural Gas, Steam and Water Meters

Building + Pulse™ Connector

Connecting to Carlo Gavazzi Panel Energy Meters

Modbus RTU or Modbus TCP/IP

• The Pulse™ Connector can integrate with any

Carlo Gavazzi Modbus enabled meter.

• All parameters collected in the meter can be

transferred to the Pulse™ EMS.

How is the Pulse™ EMS deployed?

1. Initial Site Assessment / Technical Scope

2. Hardware Installation / Software Integration

3. Account Access and Training

The Landing - Background

• Commercial and residential

complex in downtown

Vancouver

• 200,000 square feet

• 32 tenants, including three

restaurants and 3 retailers

• Consumption: 350-400k

kWh per month

The Landing - Goals

• Reduce annual electrical

consumption by 10%

• Reduce monthly peak

electrical demand by 5%

• Baseline water and gas

usage by restaurants

• M & V tool for capital

projects

The Landing – Installation

• Logistical challenge

– Hardware spans 3 floors,

water/gas meters in tiny

chambers

– Outage Scheduling

challenges

– Wireless Modbus network

for water/gas meters

The Landing – Installation

• Easy part - 8 x EM-26

CG panel meters - easy

and clean installation

– Multiple electrical

parameters (ie.

voltage, current,

power factor)

– High accuracy M&V

The Landing – Expected Benefits

• Occupant Engagement on Conservation Strategies

• More accurate tenant billing

– Incentives to reduce consumption, peak demand

• Preventative maintenance

• $15,000/yr electrical savings

• 70,000 kg/yr of GHG emissions mitigated
