Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	30,483,494.30 Kilowatt-hours	104,009.68 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	74,724 MMBtu
Imported steam, hot water, and/or chilled water	11,587 MMBtu

Total site energy consumption, baseline year:

190,320.68 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

219,147.10 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	April 1, 2015	March 31, 2016

A brief description of when and why the energy consumption baseline was adopted:

---

Source energy

Source-site ratio for imported electricity:

2.05

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.76 MMBtu per square meter	1.16 MMBtu per square meter
Baseline year	0.87 MMBtu per square meter	1.37 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

15.15

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Green Citizen Symposium 2022: This sustainability symposium had a keynote regarding making your home more resilient that included some energy efficiency practice.  

Keynote – Achieving Resilience in a Changing Climate 

Speaker – Paul Kovacs

A brief description of energy use standards and controls employed by the institution:

Most Seneca systems have been designed or retrofitted to run at variable speeds and can be throttled based on control sequences. Buildings are controlled by occupancy-based schedules, or in many cases off a sequence of operation that takes a combination of occupancy sensor data, CO2 sensor data and temperature sensor data into account.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Seneca’s main buildings have transformed most of building lights to LED lighting and a good portion of the main campus buildings use occupancy sensors as controls. In many cases, where sensors are not installed, BAS schedules are in place.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

How best to include and reward passive heating and cooling is being discussed as part of Seneca’s sustainability standards and new building requirements.

Seneca’s King campus runs a geothermal loop under one of it’s parking lots that provides heating and cooling to one of the campus’ main buildings.

A brief description of co-generation employed by the institution:

CHP has not been considered due to its implications on GHG emissions.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

ASHRAE Level 2 audits were undertaken for all campuses to better understand current operations and effective energy conservation measures. 

A steady approach has been taken to retrofit existing large pieces of equipment that are not near end of life to make them more energy efficient. The biggest initiatives have been installing VFD’s (e.g., VFD on S@Y chiller #1 in 2022 and chiller #2 in 2023) and establishing BAS control (e.g., BAS expansion to all of King campus and implementation of proper schedules for equipment)
