Description

  The present invention relates to a wood simulation system for calculating a necessary amount of wood from the number of housing sales plans and the number of construction plans.

  In recent years, awareness of environmental issues has increased, and companies have been reviewing factories and product production lines to reduce carbon dioxide emissions. In addition, there is a movement for consumers not to use shopping bags by bringing an eco bag when shopping.

In terms of carbon dioxide absorption and fixation, trees absorb carbon dioxide and do not release it to the atmosphere. And the trees are cut into timber and used as building materials such as pillars, beams, foundations, outer wall materials, inner wall materials, roofing materials, etc. Carbon dioxide absorbed by wood and not released to the atmosphere is fixed in the building material, so it is effective as a means for fixing carbon dioxide.
There are also building materials that are manufactured using thinned wood. For example, Patent Document 1 discloses a method of manufacturing an outer wall material using a thinned material, and when a house is constructed using such a building material, the thinned material can be effectively used and absorbed by the thinned material, Carbon dioxide that has not been released into the atmosphere will be fixed in the building material, and the growth of trees will be promoted in the thinned forest, so the amount of carbon dioxide absorbed will increase.
On the other hand, some building materials do not use wood at all. For example, Patent Document 2 discloses a lightweight cellular concrete board, which is formed after placing a raw material slurry mainly composed of a siliceous raw material and a calcareous raw material on a molding form. It is manufactured by curing an autoclave. In this case, it does not contain wood at all, so that the carbon dioxide absorption amount and carbon dioxide fixation amount of the building material are zero.
Thus, the amount of carbon dioxide absorbed and the amount of carbon dioxide fixed by the building material differ greatly depending on whether or not wood is included.

Therefore, in terms of carbon dioxide fixation, it is effective to construct a house using building materials made from wood. Among them, thinning materials are effectively used when building materials made from thinned materials are used. Therefore, it is preferable because thinning of the forest proceeds, and as a result, tree growth proceeds and carbon dioxide absorption increases.
In addition, timber is supplied from the forest, and if the forest owner can grasp the amount of timber to be used in the future, especially the amount of thinned wood, it can be reflected in the logging of trees, especially in the thinning plan. However, companies that start and sell houses do not calculate the required amount of timber from the sales plan or the start plan. In addition, the amount of thinned wood is not calculated.
