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

Initiating an Energy Saving Awareness Campaign in November 2019, which consist of:
• Notifications for energy efficiency tips on air conditioning equipment usage by new employee orientation booklets, posted messages around the spaces, announcements, acg blackboard and site.
• Collaboration with the IT department for implementing good practices on pc usage.
• Collaboration with a/c maintenance contractor and technical team to shape a note of succinctly stated instructions for a/c equipment proper operation in terms of energy saving and comfort conditions.


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

Energy use standards & controls employed by ACG :
• Notifying the acg community for the appropriate temperature for all spaces during summer or winter conditions, according to the applicable T.E.E. directives Τ.Ο.Τ.Ε.Ε.2423/86.
• Controlling temperature through BMS in approx..80% of acg spaces.
• Implementing restriction policy on a/c operation for the middle season period according to T.E.E. directives Τ.Ο.Τ.Ε.Ε.2423/86


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

Use of led technology lights for all cases on spaces renovation, or new construction, or replacement of burned lights in existing rooms.


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:

2012- Upgrade swimming pool heating system through Hybrid system application
2012- Upgrade Pierce- Communication building heating system through Hybrid system application
2016- Library & Main Deree Building led lights replacement

Furthermore, all the spaces renovation projects include replacement of energy consuming equipment (heating & cooling system, lights, pc etc) with high efficiency alternatives.
