Description

The present invention relates to a building simulation system and a building design method, and more particularly, to an eco-friendly building simulation system and an eco-friendly building design method, and to an eco-friendly building simulation system and an eco-friendly building design method for reducing energy costs.

Conventionally, various measures have been devised to reduce energy consumption of buildings.

For example, there may be a method of monitoring and managing the energy consumption of a building to find a plan to reduce wasted energy of the building.

However, it has not been possible to respond in advance by seeking or reflecting the energy management plan of the building from the design stage of the building. In most cases, the focus is only on energy management after the building is completed.

Of course, in the case of building by applying high-quality or high-performance insulation or finishing materials, a corresponding energy saving effect can be expected, but there is a disadvantage of increasing construction costs, The use of materials is not considered at all. For example, the intensity of wind may be very strong at a place where a building is to be built, and depending on the wind direction, insulation materials or finishing materials of a specific part of a building may vary. In addition, materials optimized for the part of the building exposed to sunlight may be used.

However, since the annual climate of the place where the building will be built is not designed in advance, the energy management of the building remains an ex post response.

On the other hand, in the case of a building as above, the insulation performance may vary depending on the direction or material of the exterior surface, and it may be necessary to review how the energy performance or insulation characteristics of the building are working after the building is actually built.
