In a broad sense, BIM not only includes multi-dimensional data information model, but also two-dimensional CAD parametric design pattern is a form of BIM.
Due to the shortage and price increase of oil resources, energy conservation and efficiency has become a problem that many industries need to consider.
Digital implied carbon is a concept not well known by the general public.
Nearly 8% of the world’s carbon dioxide emissions come from traditional concrete, and up to 80% of the implied carbon in buildings comes from structural materials.
The model is considered to provide information on the integration of construction products from concept, design, construction to the whole life cycle of construction.
The second is simulation, which simulates the process of architectural design, construction and operation.
The ultimate application of BIM is to improve the quality and efficiency of design and construction and change the business model of architecture.
Through digital design, BIM simulates the construction progress and cost control of construction, integrates the Design Institute, the owner, construction, suppliers and equipment manufacturing, and makes it possible for the complete and integrated delivery of engineering projects.
Through simulation analysis, increase the utilization of natural resources and renewable energy.
Some people also translate this into plastic mold.
For example, through passive means, reduce building load and fundamentally reduce carbon emissions in building construction and operation.
With the carbon peak in 2030 and the carbon neutralization policy in 2060, low-carbon technology is an important guarantee for the establishment of a low-carbon society.
One is the model, which is a working mode rather than a simple physical model.
In order to meet the growing needs of mankind, it is expected that by 2060, the global construction area will have an amazing growth of 230 billion square meters.
According to relevant data, the construction and operation of buildings account for 36% of global energy use and 39% of energy related carbon dioxide emissions.
The application of BIM Technology, digital construction, intelligent operation and maintenance and IOT technology make low-carbon buildings possible.
The construction industry is also one of the largest sources of emissions in the world.
It refers to the total amount of greenhouse gases released by products or services in the whole supply chain in addition to the carbon generated in the actual production process.
The core value of BIM lies in information, which is the product of the era of big data.
I stands for information.
The use of information technology makes low-carbon development a simple and sustainable development, and forms an ecosystem coupled with the natural environment.
That is, before the commencement of the project, the owner shall convene the designer, constructor, material supplier, supervisor and other parties to make a BIM model, similar to the “model to be completed”.
As one of the industries with the largest amount of data and the widest application range, the construction industry is bound to promote the arrival of the era of big data and intelligence in the construction industry with the maturity and popularization of BIM Technology.
In 2002, Autodesk connected the initials of building information modeling and became the well-known “BIM” today.
Background of BIM Technology in 1973, the first global oil crisis broke out.
B stands for architecture, which can also be considered as the whole civil engineering category, including urban planning, civil engineering, architecture, building environment and equipment engineering, building energy-saving technology and engineering, etc.
Many people are not unfamiliar with it, but their understanding of BIM only exists in 3D mold turning or project display.
In addition, ventilation, lighting and air quality are simulated and optimized to reduce the use of fossil fuels in buildings.
In 1999, building product model was proposed.
On the other hand, the materials used in the construction industry account for more than 30% of the global exploitation of natural resources.
In 1975, professors of Georgia Institute of technology proposed building description system to realize the visualization and quantitative analysis of construction engineering problems and improve the efficiency of engineering construction.
The application of BIM Technology will be the cornerstone of low-carbon buildings* The picture comes from the network BIM: the gene genealogy and source code of the construction industry refer to BIM.
As an implicit carbon calculator, BIM will map various materials with a single element after the completion of detailed architectural design..
However, this is only the tip of the huge iceberg of BIM.
Therefore, sustainable development must rely on low-carbon options.
Introduction as one of the oldest industries of mankind, architecture is facing great challenges.
On the one hand, there is a huge demand for the construction industry by global urbanization and population growth: since 2007, more than half of the world’s population has lived in cities; By 2030, this figure is expected to rise to 60% .
The carbon emission in the whole life cycle of buildings includes five parts: acquisition of building materials, project planning and design, construction and installation, building use and maintenance, demolition and cleaning.
Therefore, B represents the breadth of architecture and the whole construction field.
M has two meanings.
BIM Technology integrates the source code of the whole construction industry through digital information means.
In the design stage, BIM Technology is used to analyze the building energy consumption simulation data, and advanced technical means are used to achieve low carbon and high comfort.
It can not only carry the basic data of the whole project, but also integrate a large amount of data in the whole life cycle.
The long-standing problem of the construction industry is the fragmentation of information and the low degree of digitization.
That is, the implied carbon can be traced back to the pre production stage of obtaining raw materials.
BIM represents a new concept and practice, that is to reduce all kinds of waste in the construction industry through the application of information technology and innovative business model, so as to reduce the carbon emission of buildings* The picture comes from the calculation and construction of implied carbon in network buildings.
Low carbon technology is the guarantee for the whole society to enter the low-carbon development, and BIM Technology is the source of the construction industry entering the era of low-carbon technology.
