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

Baseline and performance energy was developed from actual utility company bills. baseline of 2009 was chosen because the major energy conservation measures were implemented beginning in 2010 to end of 2015. SJU has a web-based Utility Tracking System for all 220 utility accounts.

A brief description of any building temperature standards employed by the institution:

Cooling season 73 to 78 degrees F. Heating season 68 to 72 degrees F.

A brief description of any light emitting diode (LED) lighting employed by the institution:

(132) 25 foot pole roadway and parking lot fixtures were retrofitted with 85 watt LED kits in 2010. And presently the entire campus is undergoing a LED upgrade for all interior lighting amounting to 55,000 lamps / fixtures to be completed by mid August 2016.

A brief description of any occupancy and/or vacancy sensors employed by the institution:

SJU install occupancy sensors in 90% of all interior offices, classrooms, some corridors in the year 2011.

A brief description of any passive solar heating employed by the institution:

A brief description of any ground-source heat pumps employed by the institution:

A brief description of any cogeneration technologies employed by the institution:

A brief description of any building recommissioning or retrofit program employed by the institution:

Staten Island campus is currently being re-commissioned as per the Local Law 87. Queens campus Local Law 87 filing for re-commissioning is required by 2020. Queens campus operations is being re-commissioned system by system to be ready for the LL87 deadline.

A brief description of any energy metering and management systems employed by the institution:

27 buildings on the SJU Queens Campus are on the Lucid Design / Building Os dashboard.

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

All Laundry Rooms have been fit with water/energy efficient washers and dryers. Upgrades to high efficiency chillers has been on-going since 2010.

A brief description of any energy-efficient landscape design initiatives employed by the institution:

The University campus includes outdoor shade areas for gathering,site lighting and parking garages have been upgraded with energy efficient lighting, roadway and parking lot lighting has been upgraded with LED, and most of all roofing systems incorporate reflective coatings.

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Most all vending machines have sensors and LED lighting.

A brief description of other energy conservation and efficiency initiatives employed by the institution:

The most current energy conservation measure is the campus-wide conversion to LED lighting which is cost shared with the local utility company. All renovation projects employ energy efficient equipment. Re-commissioning systems is on-going. Training staff is on-going, most recent is the two day workshop where SJU hosted the Boiler Efficiency Institute.
