Energy efficiency and GHG emission standards for NFB production

The objective of the NFB project is to reduce the annual growth rate of GHG emissions by displacing the use of fossil fuels and the usage of good quality soil for brick making through the increased production, sale and utilization of non-fired bricks in Vietnam. The assignment is part of project’s component 1 “Policy support for NFB technology development”.

Implementing team fulfilled all outputs and requirements set by the project management unit and donor, which responded to two key objectives as follows:

• Comparison of energy consumption and GHG emission performance of Concrete Brick and of Fire Clay Brick production in Vietnam;

• Develop product-based standard for energy efficiency and GHG emissions for Concrete Brick in Vietnam.

The deliverables including two final reports corresponding to the two objectives and company assessment reports were submitted and approved by project management unit and donor by September 2018.

Company site survey and data collection: Questionnaires were developed for collecting data relating to brick production. here were 6 and 7 companies participating in the site survey activity under objectives 1 and 2, respectively, in the period of December 2017 – January 2018. This served to identify and collecting all data related to energy consumption and GHG emissions from different stages of a brick’s life cycle.

Data analysis and reporting: The implementing team conducted data analysis based on practical data from survey and recognized factors and calculated the energy consumption and corresponding GHG emission for each stage and accumulated “cradle to gate” for functional unit of FCB and CB. Report on objective 1 discusses and highlights the advantage of reduced energy and GHG emission from CB over FCB production in Vietnam, while the report of objective 2 delivers the product based standard for energy efficiency and GHG emissions for CB in Vietnam.
