Energy efficient building is critical to respond to the fact that buildings account for more than 30 per cent of total energy use in emerging economies like Vietnam. The green building development seems like a sensible answer to put achieve the government’s goal to reduce greenhouse gas emission by 8 – 10 per cent between 2011 and 2020.
According to the World Bank, Vietnam’s energy consumption has quadrupled within the last decade, resulting in a 12 per cent increase of carbon dioxide emissions.
According to Nguyen Cong Thinh, the Deputy of Director of the Department of Science, Technology and Environment, the Ministry of Construction focuses more on facilitating more projects resource-efficient.
Thinh stated that the raise of energy consumption in buildings is due to increasing fuel prices, rising living standards, urbanization and the growing number of the building. Energy consumption in the civil sector accounted for 22.4 per cent by 2003 and is estimated to have increased 37 – 38 per cent last year.
Debunking green building myth
According to Autif Sayyed, a green building specialist for East Asia and Pacific in IFC, emerging markets including Vietnam has huge yet untapped potential for energy saving, due to false belief of green buildings that are considered to be more costly compared to the conventional ones.
To cope with the issue and help the market players implement the optimum green building practices, IFC released Excellence in Design for Greater Efficiencies (EDGE), a new green building certification system that empowers developers to reduce the use of energy and water by 20 percent.
EDGE offers free software for designers to choose technical solution whilst showing the extra costs to build green as well as the payback period.
