Suggestions from diagnosis

Energy saving diagnosis for air conditioning equipments could be assumed very valuable for universities which are located in very warm climate.


very valuable for universities which are located in very warm climate.

• Energy saving for air conditioning and lighting is efficient for classroom and public space for university

– Air conditioners electricity consumption share is large at classroom buildings and it differs from factory or data center. Also for university located in very warm climate, air conditioner has significant impact.

• Energy saving by efficient operation on air conditioners are also importantIt is expected to have great effect by managing strictly on setup value of temperature– It is expected to have great effect by managing strictly on setup value of temperature

– Automation will be possible by installing BEMS (same for lightings). Especially for public space.

• Scheduled control of equipments should be implemented to turn off the equipmentsequipments

(School curriculum and student behavior usually take place by schedule and therefore it is rather

easy for schedule control and effect is large compared to other facility. )

– At the beginning start with turning off all of air conditioner and lighting at specified time

S– More detailed energy saving automated control is capable by improvement of controlling technology such as BEMS

• Since some includes large investment, it is important to improve on equipment update schedule

Unreasonable invest for equipment should be avoided and renew the equipments to energy saving equipments


– Unreasonable invest for equipment should be avoided and renew the equipments to energy saving equipments according to equipment lifetime from aging degradation.

– It is crucial to judge balance between energy loss by aging degradation and technology development on energy saving
