Electrical Energy Usage Audit

 Electrical energy is used to generate heat or motion 

Electric Heat generated for specific applications such as lighting and other specific application

 Electric Heat generated from applications to generate motion is wasted energy

 Wasted Electric Heat is expensive

1.       The cost of purchasing the power
2.       The degradation of the motors and equipment generating the heat
a.       Motors
                                                                           i.      Rapid deterioration of motor winding insulation (50% of life expectance for every 10 C extra heat)
                                                                         ii.      Motors running at 40 C will have a life of 1/16 of normal expectancy
                                                                        iii.      60% of motor failure are due to overheating
                                                                       iv.      Motor Bearings failure can be attributed to internal motor overheating
b.      Bearings
                                                                           i.      Inadequate or improper lubrication
                                                                         ii.      Incorrect alignment
                                                                        iii.      Source of ignition to surrounding material
3.       Power loss due to overheating of power distribution system
a.       Circuit Breakers /  switches
                                                                           i.      Loose connections
                                                                         ii.      Undersized electrical connectors
                                                                        iii.      Corrosion
b.       Wire
                                                                           i.      Undersized
                                                                         ii.      Compromised by 
4.       Damage to attached or nearby equipment
5.       Downtime required to repair or replace heat compromised equipment
6.        The cost of removing the excess heat from the environment

The Infrared Thermal Imaging instrument is the most cost effective method of identifying equipment generating excess and undesired waste heat. It provides

1.       Thermal Images of the compromised equipment while under load with relationship to the ambient temperature.
2.       Comparison to previous e3xamination showing variations
3.       If the equipment can be seen even at a distance,  abnormalities can be reported. (Problem equipment not visible to the eye will radiate heat that can be observed by the instrument)
Infrared Thermal Imaging is a non destructive testing process that examines equipment under normal operating conditions.  There is no disruption to the production activity.



Energy Efficiency Audit

Will identify sources of energy loss in excess of acceptable limits within the facility such as

1.       Doors, windows, walls, ceilings for air infiltration and insulation effectiveness
2.       Electric motors operating at temperatures exceeding manufacturers specifications
3.       Gearboxes, bearing, bushings, pumps operating at temperatures exceeding manufacturer specifications
4.       Electrical panels, switches, breakers at temperature significantly above ambient temperature
5.       Electrical conductors / wiring with temperature above ambient temperature
6.       Lighting fixture efficiency
7.       Flat roof temperature that is compromised by the presence of moisture within the roof membrane
8.       Piping or ducting where the insulation effectiveness has be compromised
9.       Water heating devices efficiency, calcium buildup, insulation 
10.   Boiler / furnace examination for cracks or deterioration in the combustion unit
11.   Boiler / furnace insulation effectiveness
12.   Steam piping for corrosion, reduced capacity, steam trap contamination 
13.   Chimney / flue temperatures, cracks or deterioration
14.   Refrigeration compressor, condenser , evaporation and pressure line temperatures exceeding manufactures specifications
15.   Leaks (water / steam) from piping that is visible, behind walls or buried in earth or concrete
16.   Compressed air systems , compressor, condenser,  piping, tools  

The energy losses will be recorded with a determination of the estimated lost energy units and value.


Another significant component of energy cost is “demand” charges or Peak Demand for Electricity and Natural Gas which are determined by

1.       Peak usage charges
2.       Contracted minimum and/or maximum usage 
For high voltage services 3 phase, unbalanced usage can be a notable cost
In addition to the measuring of usage and identifying excess consumption the Audit will recommend solutions to the problems.
The solutions may involve recommendations to 
1.       Adoption of more efficient operational procedures
2.       Repair existing equipment, facilities, etc.
3.       Replacement of existing equipment with more cost effect apparatus 
4.       Introduction of new processes
5.       Training of staff to become more energy conscious
To encourage energy efficiency there are a number of programs sponsored by

1.       Natural Resources Canada, Office of Energy Efficiency   (

2.       Ontario Power Authority / Hydro One in association with your local provider (SaveONEnergy ) (

3.       Union Gas   (savemoneyandenergy)  (


These programs may provide funding for

1.       The cost of the Audit

2.       Modifications to existing facilities

3.       Installation of more efficient equipment

4.       Training or hiring staff to improve efficiency


The FIRST step to saving money and improving your efficiency is

1.       Contact Thermal for a preliminary no cost no obligation audit of your facilities to determine if savings are a possibility


(If you desire to have funding support from the above agencies an Energy Audit must be undertaken with the following steps)


2.        An application(s) for funding support will have to be filed with the agencies involved.  Thermal will assist it the preparation.

3.       Upon approval of the application the Audit with required supporting reports will be prepared by Thermal for management and the funding body.

4.       If managements desires to implement any or all of the recommendations then

a.       If funding support is not required the work can commence as deemed appropriate

b.      If funding support is desired an application will have to be made to the funding authority

(upon approval, remediation can be initiated)
