Description

  The present invention relates to a housing simulation system.

  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 terms of absorption and fixation of carbon dioxide, trees can absorb carbon dioxide. The trees are cut into timber and may be used as raw materials for building materials such as pillars, beams, foundations, outer wall materials, inner wall materials, and roofing materials used when constructing a house. In this case, the carbon dioxide absorbed by the wood is fixed in the building material and is effective as a means for fixing the 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. 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 is not released into the atmosphere will be fixed in the building materials, and in the thinned forest, tree growth will be promoted and carbon dioxide absorption will increase.
On the other hand, there are building materials that 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 autoclaving and does not contain wood, so the amount of carbon dioxide absorbed and the amount of carbon dioxide fixed 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. In addition, the carbon footprint of building materials varies greatly depending on the material transport distance and manufacturing process.

  However, when choosing a house, carbon dioxide fixation amount, carbon dioxide absorption amount, carbon credit, carbon footprint, etc. are not taken into consideration, design drawings are created, floor plan, roof shape After determining the position of the opening such as a window, the construction of the inner wall and the outer wall is stopped by arranging a plurality of building materials having various shapes, dimensions, patterns, patterns and colors.

  For example, Patent Document 3 discloses a system that realizes a simulation for creating an exterior design of a house between a server and a client connected via a network. According to this system, by using a client device, data such as building material images necessary for simulation is acquired from the server device, and pasted on house image data or the like that is held in advance in the client device. However, it is not possible to calculate and take into account carbon dioxide fixation, carbon dioxide absorption, carbon credits, carbon footprint, etc.
