Part 1

This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 71,000.81 MMBtu 49,551.11 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 50,593.12 MMBtu 68,084.10 MMBtu
Total 121,593.93 MMBtu 117,635.21 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year April 1, 2017 March 31, 2018
Baseline Year April 1, 2009 March 31, 2010

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
UWinnipeg began a major energy retrofit process in 2009. Key initiatives include a series of building controls retrofits, a major ventilation retrofit (ongoing), a series of boiler replacements for buildings that are not connected to the University’s main heating system, and the installation of a hybrid heating system that uses lower-emitting electricity for heating at off-peak times. A single year was chosen instead of a three-year span b/c during this time, the physical footprint of the campus has grown year over year.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 144,166.88 Gross square meters 103,592.96 Gross square meters

Source-site ratio for grid-purchased electricity:
2.05

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.08 MMBtu per square meter 0.11 MMBtu per square meter
Source energy 0.13 MMBtu per square meter 0.15 MMBtu per square meter

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
16.93

Part 2 

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 5,629 Degree-Days (°C)
Cooling degree days 133 Degree-Days (°C)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 7,095.28 Square meters
Healthcare space 0 Square meters
Other energy intensive space

EUI-adjusted floor area, performance year:
1,704,545.32 Gross square meters

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
6.88 Btu / GSM / Degree-Day (°C)
