The initiatives undertaken post energy audit in 2010 for Energy Efficiency.

• - Replacing efficient tube lights and electronic ballast.
• - Changing Resistance type fan regulator with electronic type.
• - Setting the temperature of AC at 25 - 26^oC as per institute orders.
• - Changing the hot plate in pantry of different offices with gas based stoves.
• - To streets (of maximum density of the students users) have been installed with LED based lamps on experimental basis.
•  

Electric transport system within campus.

•  
• - Over 15 e-rickshaw (private owned) operating within Campus and to City/Bus Stand/Railway Station.
•  

Use of green materials for construction

• - Use of Autoclaved Aerated Concrete (AAC)-a green building material.
• - Porous, non-toxic, reusable, renewable and recyclable.
• - Uses fly ash, cement, lime, water and aerating agent.
•  
•         
•  
• - Low Thermal Conductivity.
• - Superior sound absorption qualities.
• - Reduced Heating /AC Load about 30%
•
