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

This baseline year was adopted due to the new construction that was to be completed on JJC's main campus over the next few years. JJC had the desire to monitor the energy consumption and mark the changes, as we added new buildings that were designed with new energy savings guidelines.

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

During occupied mode, spaces are generally set to 68F in heating season and 74F in cooling season. During unoccupied modes, temperatures are reset to 62F for heating and 82F for cooling.

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

Approximately 60% of the campus space is served by LED fixtures including nearly all of the lighting in recent campus additions.

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

Approximately 60% of the campus spaces is connected to occupancy sensors including nearly all of the lighting in recent campus additions. Vacancy sensors are being added to new projects as Energy Code dictates.

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

The Facility Services building has a passive solar heating system on its outside air system. Exterior ductwork is mounted on the roof of the building and during periods with cold and sunny ambient conditions, outside air is routed through the ductwork to pick up heat prior to entering the air handler.

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

Three new projects completed within the last couple years include the use of ground-source heat pumps. The Campus Center renovation and addition and the Facility Services building implement water-to-air heat pumps connected to a geothermal loop. The Health Professions Center uses water-to-water heat pumps to generate heating water and chilled water that is distributed to a chilled beam and centralized air handling unit system. The water-to-water heat pump are also served by a geothermal loop.

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:

A comprehensive retro-commissioning study was performed by Illinois Smart Energy Design Assistance Center (SEDAC) and recommendations are starting to be implemented for Building T and C-G. Additional studies are currently being performed on Buildings H, J and K.

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

The entire campus is currently connected to a Building Automation System (BAS). Some areas of campus have greater monitoring capability than others, however, all recent additions and renovations have provided significant metering and alarming capabilities of the HVAC systems. Additional upgrades are planned for areas that have less BAS capabilities.

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

JJC completed a Facility Condition Assessment in 2008. This assessment is a living document that provides total useful life of mechanical equipment and interior space elements. When energy consuming equipment has reached its useful life, Facility Services works with the Business office to specify energy efficient replacements and procure those pieces of equipment.

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

The 2008 Master Plan developed a landscape master plan. All landscape is now native drought resistant landscaping. Integrated Pest Management was also employed at that time.

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

JJC has required in the vendor contracts that energy efficient machines must be provided. We have also required the vendor to turn off the lighting on these machines and have place placards on the machines to communicate the machines are still on even though the lighting is off to save energy.

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

We are currently retrofitting all interior and exterior lighting to LED. We are approximately 50% completed across all campuses. We have installed water misers on all of the sink faucets, low flush toilets/urinals, and motion sensors on all classrooms and all offices. We are also implementing two stage lighting on all stairwells. We converted one building from pneumatic to DDC and are planning to retrofit the remaining buildings. Carpet is standardized with Interface recycled carpet tiles throughout all campuses. We also replaced 90% of all roofs with white EPDM roofing systems.
