On December 26, the Department of Industry and Trade of Da Nang City coordinated with the Consortium of Yokohama National University and Osumi Co., Ltd. (Japan) to organize the Closing Ceremony of the Project to Promote Energy Saving for People of Da Nang City, Vietnam.
The project will be implemented from 2020 to 2024 in Son Tra district (Da Nang city) with the aim of improving the quality of life of people in Da Nang city through implementing measures to use energy economically and efficiently. Raising people's awareness of using energy economically and efficiently, contributing to environmental protection.
After 4 years of implementation, the project has surveyed 300 households and 50 non-residential buildings (hotels, office buildings). The survey results show that more than 50% of electricity consumption is for cooling purposes (air conditioning, fans). Actual measurement equipment was installed for 60 households and 8 non-residential buildings (including 4 hotels and 4 offices).
Support the implementation of energy-saving renovation measures for 4 households using air conditioners in their bedrooms (such as applying heat-insulating film to glass doors, applying insulation foam inside the ceiling/wall of the bedroom using air conditioners) and 1 household not using air conditioners (in addition to applying the above measures, the project installed 1 air conditioner for the bedroom and 1 solar panel on the roof). After renovation, electricity consumption has decreased from 6.8% to 19.1%.
Mr. Nguyen Van Tru, Deputy Director of the Department of Industry and Trade of Da Nang City said: "The project has a strong influence and influence on the residential community in Son Tra district. We hope that after this closing ceremony, it will continue to open up new cooperation opportunities in the field of energy saving in particular and the spirit of cooperation in general between Da Nang and JICA, directly including Yokohama city."
Solutions that have been effective in reducing energy consumption include insulating the building envelope to reduce energy consumption by 10% - 15%. Using high-performance double-glazing for windows to reduce energy consumption by 13% - 20%. Switching from fluorescent lights to LED lights to reduce energy consumption by 50% - 67%. Using energy-efficient air conditioners to reduce energy consumption by 20%.
The project also organized 3 model classes for students on home insulation solutions and ventilation and cooling methods. Aiming to reduce the cooling load for air conditioning, save energy, and reduce CO2 emissions.
