Energy efficiency and conservationin the construction and the developmentof green building
ECAP 14 Tokyo 2017

Mr. Nguyễn Văn Long
Energy efficiency and Sustainable Development Department
Ministry of Industry and Trade- In the recent years, the average floor area of new construction in
Vietnam is about 80-90 million m2/year.
- The area of working offices, hotels, department stores has rapidlyincreased.
- In the large cities, the medium and large-sized buildings areincreasing.
- The increasing of numbers of buildings, size of the floor area resultin the energy consumption in this area increasing significantly
every year.
- In 2015, the energy consumption in the civil sector in Vietnam
accounted for 15.1% of total national energy consumption.

The legal documents on energy efficiency andconservation in the construction

In 2010, The Law on Energy Efficiency and Conservation was approved by theNational Assembly

In 2011, the Government issued Decree No.21/2011/ND-CP detailing the Law on
Energy Efficiency and Conservation and measures for its implementation.

In September 2013, the Ministry of Construction issued the TechnicalRegulation on Energy Efficiency Buildings.

The implementation of energy efficiency andconservation in the construction and thedevelopment of green building
1. Implementation of National Regulation on Energy Efficiency
Buildings (QCVN 09:2013/BXD) :- Coordinate with IFC-WB to develop a check list, tool, technicalguideline for applying QCVN 09:2013/BXD- Organize seminars/ workshops, training courses for dissemination ofthe Regulation.
- Select 05 works for pilot applying the energy calculation, work design
aiming to meet the requirements of the Regulation from the design phase (03works under IFC project and 02 works under Danish Project).

The implementation of energy efficiency andconservation in the construction and thedevelopment of green building (Cont.)- Establish the list of more than 400 works with the floor area scale
over 2500m2 in Hanoi, Hai Phong, Da Nang, Ho Chi Minh City andCan Tho.
- Select 225 works for conducting surveys, detailed energy audits.
Propose to conduct surveys in 5 cities: Da Nang, Can Tho, Ho ChiMinh, Hai Phong from February 2015 to 2016.
- Set up the energy use database management software in thebuildings in 5 cities, then replicate to other regions.
- Capacity building for 02 Energy Conservation Centers in Hanoi
Architectural University and Ho Chi Minh City ArchitecturalUniversity.
- Develop the teaching materials on energy saving for teachingdelivery in Architectural University and Civil Engineering
University.

Concrete ceiling and floor, use air pressure concrete block for walls andspilited walls

Cluster of FPT building, Da NangThis 6 storey building has a 1,500L solar hot water system and a solar-powered
generator with capcity of 12kWh/ day. The complex has a football field, basket ballcourt, park, swimming pool. The return on investment of energy efficient technologiesof the facility is less than 3 years due to the reduction of energy costs..

materials usedBarriers related to the implementation of energy
efficiency and conservation in the construcion anddevelopment green building- Shortage of human resources implementing the energy
efficiency program and development of green building. There isno specialized unit in this sector especially in the localities.
- The limitation of financial resources, state budget forenergy efficiency investment;- The limitation of professional capacity of technical experts
in the field of energy efficiency.
- The application and development of green building are justvoluntary, based on the consciousness of the project investor.
- There are no specific and appropriate incentives for energy
efficiency projects and certified green buildings.

Some solutions for promoting the energy efficiency andconservation in the construction and development ofgreen building• Studying, screening, supplementing, formulating and issuingnorms, unit prices, investment rates related to energy
efficiency and green building.
• Formulating and promulgating specific incentive mechanisms
for energy efficiency buildings which are certified as green
building (incentives in tax, fees …)• Strengthening dissemination activities, raising awareness forthe concerned subjects in the energy efficiency, developmentof green building.
• Developing and implementing the regulations on assessment,
certification, labeling, certificate granting for materials,
equipment, energy efficiency buildings, green buildings.

Thank you very much!
