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 24,879,310 Kilowatt-hours 84,888.21 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 474.23 MMBtu
Imported steam, hot water, and/or chilled water 73,646.30 MMBtu

Total site energy consumption, baseline year:
159,008.74 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
1,463,371 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period Jan. 1, 2015 Dec. 31, 2015

A brief description of when and why the energy consumption baseline was adopted:
JJC's main facility, The New Building, opened fully in 2012. The baseline period selected allowed for time to implement sequence of operations settings. The performance period was selected for before COVID curtailment of onsite operations.

Source energy

Source-site ratio for imported electricity:
3.34

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.07 MMBtu per square foot 0.18 MMBtu per square foot
Baseline year 0.11 MMBtu per square foot 0.24 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
27.81

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
We have “close your sash” signs on chemical fume hoods and explain why during training.

We send out informational emails and post signage about peak energy which explains why this is very important. We ask Sustainability Council members to also disseminate the informaiton.

A brief description of energy use standards and controls employed by the institution:
Our centralized energy management system controls building cooling and heating and based on occupancy schedule. During unoccupied winter period, building temperatures are set back. During summer unoccupied period, cooling and lighting will be reduced.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
John Jay has undertaken a project to replace fluorescent lamps with LED lamps wherever possible. LED lamps are the industry leader in efficiency and have become the technology of choice for our renovation projects. Approximately 50% percent of our fixtures have been replaced with LEDs in our New Building and Haaren Hall.

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

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

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
John Jay College follows NYC's Local Law 87 of the City's Greater Greener Buildings Plan, which requires all buildings over 50,000 sqft to perform an ASHRAE Level II Energy Audit and Re-commissioning study every 10 years. JJC uses these studies to direct it's efficiency projects that focus on operational improvements. These studies frequently recommend setpoint adjustments in buildings, lighting upgrades, existing system upgrades or tuning, and appliance improvements.

Data source(s) and notes about the submission:
Steam from Con Edison is used for heating the buildings. All of the natural gas used on-site is for cooking only. Diesel is used for the monthly generator test.


The site to source EUI conversion factor of 3.34 for electricity is from EO 88 guidelines https://www.nypa.gov/-/media/nypa/documents/document-library/operations/buildsmart-ny-eo88-guidelines.pdf
