Green materials are interested by consumers not only for the purpose of protecting the environment but also for practical benefits for users. Green materials being used to replace “unclean” materials can be mentioned as: Low VOC paint, artificial wood, concrete bricks, lightweight bricks, safety glass, soundproof glass, insulation. heat, unburnt bricks…

In the past time, the State has completed a number of standard frameworks on safety and energy saving for construction works and there have also been a number of prohibitions on with materials that are harmful to health such as asbestos or with limited manual kiln fired clay bricks. However, there are still some investors who use or intentionally use “unclean” materials when building works for profit purposes, ignoring environmental issues.

In order to improve management efficiency, save and use energy efficiently, the Government has issued Decree 10/2003/ND-CP on “Using energy savings and efficiency”. In the content of the Decree, there is a chapter referring to the issue of economical and efficient use of energy in construction works. Then, on November 17, 2005, the Ministry of Construction issued Decision No. 40/QD-BXD promulgating Vietnam Construction Regulation QCXDVN “Construction works using energy efficiently”. However, since then, many construction projects have continued to use unsafe and non-energy-saving materials, including those that have been put into operation since 2007 (since the Law on Housing and Construction). in effect). These are some of the great shortcomings of project planning consultants, design consultants, design verification consultants, and construction quality inspection and certification consultants.

For example, the use of construction glass in construction works and social life. Many apartment buildings in Hanoi, especially residential houses today, the glass used is still single-layer glass, clear glass does not meet the requirements of heat transfer coefficient and safety. Therefore, when receiving and using apartments in these buildings, the above mistakes are very difficult to overcome, or homeowners cannot know that the above materials are not clean to still accidentally throw money through the window. Because if you use unsafe glass, it will be easy to fall in a storm and cause injury, or spend money on air conditioning when the aluminum frame door still transmits heat from the outside…

With these works, if people buy houses to sue in court, the above consulting organizations must pay money to the temple in accordance with the provisions of Government Decree No. 209/2004/ND-CP dated 16/12/2004 on quality management of construction works. It is time for homebuyers to ask the investor to publicly announce the application of standards on building materials for products sold on the market. Require investors to publicly and transparently frame contracts on house purchase and sale, which commits to the use of clean materials for homebuyers. At the same time, the local State management agency in charge of construction also needs to upgrade the quality in reviewing and improving the quality of using clean materials that are required in the national regulations. Inspection and certification of construction materials in accordance with the quality of construction works must be one of the mandatory regulations.

Deputy Minister of Construction Nguyen Tran Nam:

In Switzerland, green buildings have saved 3/4 of electricity, reducing electricity consumption/m2 of construction to 25% (compared to buildings) normal) and in our country it is also necessary to have policies to encourage “green building”, “green architecture” development. Go to green certification for standard works and consider it as a standard for sales. The reality is that the State management agencies must urgently issue guiding and mandatory standards and regulations for practical application. beneficial to society, users and investors. In the second quarter of 2011, the Ministry will fully issue the above legal documents to help design, construction, inspection, supervision, acceptance, payment and settlement of works.
