【4】Topics of the Activity
in Brunei Darussalam< Topics >(1)Minister of Energy attended the Seminar/Workshop(2) The lectures about the energy audit was implemented
and many trainees attended the training(3) Follow-up survey was successful (14.5% improved)

【4】Topics of the Activity (continued)
Activity in Philippines< Topics >（1）Energy Conservation Measures in Government
Buildings (Grading System) are very effectively implemented.
(2) Pre-audit on the office building to be audited was implemented
by the focal point and it made the audit successful.
(3) The Price of Darkness: The top management forced
the employee to implement EE&C for saving lighting energy.

【4】Topics of the Activity (continued)
Activity in Vietnam< Topics >(1) Pre-audits on the two buildings to be audited in PROMEEC
had been implemented and it made the audit activity
successful.
(2) University of Tech. of HCMC participated and supported
the PROMEEC activities(3) ECC-HCMC is very active for the promotion of EE&C in theregion.

Estimated Saving (kWh) by the Recommendation

ECCJ【7】 For Future Activities(1) For the Improvement of Energy Audit OJT Activities for the Local
Engineers• Sufficient Information and Data for Fruitful Energy Audits(1) Sufficient information and data to be provided with to the experts in advance of theenergy audits(2) Pre-audits were very effective for the successful audits(3) Excellent preparation by Philippines (one office) & Vietnam for the energy audits

・ More involvement of the local participants to the energy audit work
(1) The participants to carry out the analysis of the results of the audits (measurement,calculation, analysis, making recommendations and to make presentation of the audit
results for the building owner)(2) The pre-audits should be carry out before the activities.
(3) More detail and exact data should be collected before the audits(2) For the Improvement of the Seminar/Workshop・ More Local (Host-country) presenters(1) Two successful cases were presented in Philippines.
(2) The audit results obtained from the their own audits to be presented

【8】 Conclusions
To remove the identified barriers step by step through thePROMEEC （Building) Activities

Main identified Barriersin Buildings••••

Lack of awareness of theowners and the architects on
EE&C
Inadequate Information anddata of EE&C
Limited technical andmanagerial capability of thelocal engineers andmanagers
Financial barriers

PROMEEC Activities••
Step by Step•
Continued

Continuous Cooperation !
