1. Understanding and Using Charts in the UCD
UCD Training
March 1, 2018

2. UCD Charts vs Reports What’s the difference? same data in both
some charts also contain weather normalized data
only meters having 92% data completeness in a fiscal year will be included in the charts
Why Use Charts?
quick way to visualise trends
immediate comparison of year-over-year energy data
facility
board
easy to spot opportunities for potential energy savings

3. Background Information Glossary of Chart Terminology
Actual
the quantity of energy consumed
also known as “raw” data
also known as “metered” data (Min of Energy – Green Energy Act reporting)
Adjusted Baseline
calculated value of energy consumption based on a formula using
the quantity of energy consumed per HDD and CDD in the baseline year multiplied by the number of HDD and CDD in a selected year, plus baseload
allows users to determine if they are consuming more or less energy when the impact of weather is removed from actual consumption values
represents weather-normalized consumption

4. Background Information Glossary of Chart Terminology
Baseline Year
the baseline year is the fiscal year that the UCD uses to calculate the quantity of energy consumed per HDD and CDD
the current baseline year is FY 2013
over time the baseline year will change
Normalized
short-form terminology for “weather normalized”
see definition of weather normalized on next slide
Raw Data
the quantity of energy consumed
appears in the charts as “actual”
also known as “metered” data (Ministry of Energy – GEA reporting)

5. Background Information Glossary of Chart Terminology
Typical Year
calculated value of energy consumption based on a formula using
the quantity of energy consumed per HDD and CDD in the baseline year multiplied by the average number of HDD and CDD during the past 10 years, plus baseload
allows users to view a specific fiscal year’s consumption based on the average, normalized weather over the last ten years
Weather Normalized Data
a calculated value of energy consumption data where the difference in weather patterns across specific time periods (fiscal or calendar years) has been removed
allows apples-to-apples comparison of energy consumption
typically the baseline fiscal year’s weather is used
25-35% of energy consumption related to heating and/or cooling (where applicable) is impacted by weather

6. Background Information – Setting Preferences
Units of Measurement
users determine the unit of measurement
How to set the Unit of Measurement
go to the toolbar on the top right hand of the site
select the “wrench” icon
select the “Set Your Unit Preferences” tab
select “Unit Type” from the drop down list
select “Preferred Unit” from the drop down list
click on “Save Preference” button
when all applicable units have been selected, click on the “Done” button

7. Background Information – Setting Preferences
Units of Measurement cont’d 2. 3. 4. 5. 6.

8. Information Available in Charts
Five categories of information
Utilities
data shows the consumption of each utility by type (electricity, natural gas, fuel oil, propane etc.) on its own
Energy
data shows the total consumption of all applicable utilities
Energy Intensity
data shows the total energy consumed divided by the total floor area
Emissions
data shows the total emissions of CO2 produced
Emissions Intensity
data shows the total emissions produced divided by the total floor area

9. Types of Charts Five types of charts: Performance Line
Performance Annual Columns
Year vs Year Lines

22. Raw Data Charts Raw Data
is the quantity of energy consumed (also known as metered)
in the UCD charts it appears as “Actual”
When to use Raw Data
when comparing consumption data
in one fiscal year
for a single facility
all facilities within a board
Rationale
pure consumption data based on meter readings
meter readings as back up
no weather normalized process has been applied
Note
Raw data charts do not have the words “Performance or “Normalized” in the title

23. Weather Normalized Charts
see definition on slide 5
represented in the UCD charts as Adjusted Baseline
When to use Weather-normalized data
when analyzing consumption data for …
1. more than one fiscal year
same facility
all facilities within a board
Rationale
weather can impact consumption significantly from one year to the next
Note
Weather normalized charts have the words “Performance or “Normalized” in the title

24. Weather Normalized Charts
When to use weather-normalized data
when analyzing consumption data for …
2. more than one site
multiple facilities within a board across multiple weather stations
Rationale
weather can be significantly different from one facility to another within a board
particularly relevant for boards that cover a large geographic area

25. Weather Normalized Charts
When to use weather-normalized data
when analyzing consumption data for …
3. Multiple boards
multiple facilities across more than one board
all facilities in multiple boards
example, Peer Inventory
Rationale
weather will be significantly different from one board to the next

26. Impact of Weather on Consumption
the chart below shows the number of HDD and CDD per fiscal year at Toronto Pearson International Airport

27. Impact of Weather on Consumption
Heating Degree Days (HDD)
primarily impacts natural gas consumption
extended period of HVAC use (for heating)
electricity consumption will be impacted for those facilities with portables/portapak and all electric schools
FY 2014 was the coldest year
largest number of HDD (FY 2013 – FY 2017)
Cooling Degree Days (CDD)
will impact only electricity consumption
extended period of HVAC use (for cooling)
facilities with air conditioning (AC)
FY 2016 was the hottest year
largest number of CDD (FY 2013 – FY 2017)
