Green building development needs an overall strategy

This comment was shared by Associate Professor Ph.D Hoang Manh Nguyen, Director of Vietnam Green Urban Research and Development Institute, at the Green Cafe talk with the theme of Green School in the morning of June 12.

According to Mr. Nguyen, green construction helps minimize the negative impact of the construction environment on people and the environment by selecting the location, area of ​​use, construction materials, construction process.

These projects are highly effective in using energy and materials, minimizing adverse impacts on the environment, taking advantage and saving energy and natural resources such as water and wind, at the same time, wasting treatment and renewing energy.

Looking at the experiences of other countries, Mr. Nguyen said that green buildings in Vietnam need to be recognized and applied comprehensively on the environmental, the social, the cultural and the economic aspects to be suitable to Vietnamese conditions.

Accordingly, it is necessary to develop an overall strategy for green products to be deployed across cities, buildings, materials and construction products. Green building products are a closed process, minimizing the inputs of urban and architectural (raw materials), minimizing the outputs of urban and architectural (pollution, waste, water waste ...). Use the "origin return" philosophy to make reusing old materials as much as possible.

With green schools, we consider and assess the quality of a school in terms of: physical conditions of the environment, facilities, subjects, curriculum and internal habits.

“Concerned about these issues will help guide those in the environment with the right definition of Green. Since then, in the new life, there is a green standard thinking about the environment”, Mr. Nguyen said.

According to him, the extra costs such as in-depth design and analysis, green consulting costs, equipment and green materials, assessment and certification ... are quite small, not as we imagined if we applied the green standard from the beginning.

While the tangible benefits of green buildings can be seen as increasing selling prices, selling faster and being easier to transfer, reducing operating costs, increasing asset value. The invisible benefit of this type is the advantage of the leader, brand, competitive advantage, corporate social responsibility.

In addition, green buildings have great benefits along the life cycle, including reduced operating costs, increased construction values. This is also a creative base for marketing and branding campaigns, and creating a comfortable and healthy living environment.

According to experts, if using green architectural design measures combined with modern interior equipment, the investment cost for a green building is higher than the average of the same type of average construction of about 5%, highest about 15%.

But the cost of operating and using green buildings will be 20-30% cheaper than normal ones because of saving energy, clean water and other costs. Accordingly, after only 4 - 5 years of operation, the savings can offset the investment capital and the total savings of operating costs are growing.

Mr. Nguyen said that in Vietnam, there are a number of projects that have been evaluated and certified by green building evaluation systems such as: LEED of the United States Green Building Council; Green Mark of Singapore Green Building Council; LOTUS of Vietnam Green Building Council and an evaluation system for effective use of resources – EDGE: Excellence in Design for Greater Efficiences –by the International Finance Organization, a member of the World Bank group. The above four evaluation criteria systems are recognized by the World Green Building Council.

In addition, there are a number of other criteria for evaluating Green buildings developed by local organizations such as: Ministry of Green Building (evaluation of testing) of Construction Environment Association, Green Building Evaluation Criteria to ensure energy saving of Vietnam Institute of Architectural Planning (2009), Green Architecture Criteria of Association of Architects.

Mr. Nguyen also said that there are some difficulties in implementing the green projects. Awareness of the community, a team of experts such as architects is weak and inadequate for deep expertise. Meanwhile, the number of projects is booming, the investors are also interested in often towards the closer, immediate benefits, and less interested in long-term benefits.

Finally, as the management unit, Vietnam has no policy to encourage the green buildings. According to him, to develop this type of movement requires policies from the managers.
