Description

A system for evaluating the amount of carbon dioxide emissions per unit of building.}

The present invention relates to a system for evaluating unit carbon dioxide emissions for each material of a building. In particular, the present invention relates to a system for evaluating unit carbon dioxide emissions for each material in a design statement of a building using an inter-industry table.

As greenhouse gas emissions from industrial activities are drawing attention as a cause of global climate change, efforts to save energy and reduce CO2 emissions are being developed worldwide. In the case of Korea, “a 30% reduction compared to the predicted greenhouse gas emission by 2020” has been set as the national greenhouse gas target, and accordingly, various policies related to building greenhouse gas emission reduction are being rapidly established.

As described above, as various policies related to building greenhouse gas reduction are promoted, various studies for energy saving are being conducted in academia and industry, and research for practical application of the results is also being promoted. In the construction industry, various efforts have been made to reduce energy consumption in buildings. For example, in the process of designing a new building or improving an existing building, among the various design alternatives proposed for selection, in order to select the design alternative with the least environmental impact, quantitative environmental An evaluation technique is performed.

For environmental assessment, the technique that is mainly used is the Life Cycle Assessment (hereinafter referred to as LCA) methodology. The LCA methodology is a methodology to evaluate the amount of environmental pollutants generated during the life cycle. Through analysis of all raw materials input to produce a product, products made from them, and other emissions, environmental pollutants get evaluation results for LCA methodologies include industry-relevant analysis (input-output LCA; hereinafter referred to as I-O LCA) and process-based LCA. Process-based LCA is a method of analyzing the elements input and output in the production process through direct investigation of the production process, and a lot of time and effort must be invested in the actual investigation. I-O LCA is a method of analyzing environmental pollutants from a comprehensive point of view by using the inter-industry table announced by the Bank of Korea. This LCA method has the advantage of presenting results considering all industries and obtaining evaluation results for all products. For this reason, I-O LCA is used for environmental assessment of the entire building.

However, in the existing LCA-related studies or LCA evaluation systems, only one building material was evaluated or only a simplified evaluation was performed that included only a few simplified building materials. For example, rather than total CO2 emissions from all materials used in a building, CO2 emissions from concrete, a representative building material, were evaluated. On the other hand, in order to evaluate the environmental pollution emitted from the design alternatives proposed in the building design stage, a method capable of conducting an environmental impact assessment for all building materials included in the design specification is required. In other words, CO2 emitted from the entire building must be evaluated by reflecting all items included in the design specification in the evaluation process. And this evaluation methodology should be designed so that design participants can use it easily.

Therefore, in order to evaluate the eco-friendliness of the design alternatives, a methodology to evaluate all CO2 emitted from the design proposals must be presented. In addition, as described above, the CO2 evaluation model needs to be developed as a model that can evaluate all items of the statement submitted along with the building design drawing, and it must include convenience of use so that design participants can directly evaluate CO2. do

The system for evaluating unit carbon dioxide emissions by material of a building according to the present invention was developed to evaluate the eco-friendly value and select the optimal design alternative from the environmental point of view.
