Green building development needs an overall strategy

This comment was shared by Prof. Dr. 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 minimizing 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, making use of and saving energy and resources such as water and wind and waste and recycling energy.

Looking at the experiences of other countries, Mr. Nguyen said that green buildings in Vietnam need to be recognized and applied comprehensively on environmental, social, cultural and economic aspects 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 urban and architectural inputs (raw materials), minimizing urban and architectural outputs (pollution, waste, water waste...). Use the "origin return" philosophy to make reusing old materials as much as possible.

Prof. Dr. Hoang Manh Nguyen.

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 applied green standards 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.

There are not many green buildings in Vietnam.

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 US Green Building Council; Green Mark of Singapore Green Building Association; LOTUS of Vietnam Green Building Council and an evaluation system for EDGE effective use of resources 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 green projects. Awareness of the community, a team of expert experts such as architects is weak and inadequate for deep expertise. Meanwhile, the number of projects is booming, investors are also interested in, but often towards closer, immediate benefits, but less interested in long-term benefits.

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