Thedraft is expected to be an important step forward in improvingstandards and reducing energy consumption for public and privatebuildings, such as offices, hotels, hospitals, schools with more than2,500 square metres of total floor space.
The number of buildingssuch as houses, shopping centres and hotels has increased rapidly inrecent years. In these buildings, poor energy efficiency measures haveled to huge energy waste.
"The building sector is one of thelarge energy users, accounting for 25 percent of total national energyconsumption. Therefore, applying energy efficiency solutions forbuildings is so important," Nguyen Trung Hoa, head of the Ministry'sDepartment of Science, Technology and Environment, told Xay Dung(Construction) newspaper.
To encourage buildings to save energy,the ministry will grant the Building Energy Efficiency Certificates tobuildings that successfully meet QCVN 09:2013/BXD standards.
Thecompulsory technical requirements will be applied to buildingcomponents such as building envelopes, lighting, ventilation systems andair conditioning, lift and escalator, and heating.
The potential of energy efficiency in constructions including both old and new buildings is very high, experts said.
"Applicationof energy efficient technologies and materials, architectural designscan save around 30-40 percent of energy consumption for new buildings,"said Tran Dinh Thai, from the construction ministry.
"Forrenovated buildings, if energy audits and energy saving solutions areapplied, about 15-25 percent of energy consumption will be saved," headded.
However, the amount of energy consumption in buildingsremains high because Vietnam still lacks detailed regulations andexperts that can promote energy efficiency and conservation, said NguyenCong Thinh from the department.
"The consultant units which havecapacity in building energy efficiency are still few in number. Themost advanced design technology is energy use simulation software forbuildings which have are not yet," said Tran Thanh Vu, Energy EfficiencyConsulting experts at the World Bank Group's International FinanceCorporation (IFC).
The Ministry of Construction will alsoprovide training courses for energy managers and energy auditors toimprove the knowledge of energy conservation. In the future, this workshould be strongly promoted to meet the needs of human resources of theunits engaged in energy efficiency.-VNA
