Be green with BIM
The use of the new methodology will serve to make new cities and buildings more eco-friendly
Last April 22 was International Earth Day , a day that raises public awareness of the problems of overpopulation, pollution and the importance of preserving the biodiversity that exists on our planet.
To give us an idea of the current situation, only in the US, the construction sector is responsible for 30% of greenhouse gases discharged into the atmosphere. This country also generates more than 136 million in waste. In China, one of the world’s most populous countries, pollution levels are so alarming that the government has had to raise alarms several times, forcing the closure of roads and canceling of flights. In other parts of the world the situation is not much better, because the increase in soil temperature is causing the melting of the poles and the unevenness of the sea.
The solutions proposed by the Treaty of Paris as climate change in the capital gala signed by over 170 countries seeking to reduce emissions of greenhouse gases, but more work is needed.
The AECO sector, key in the fight against climate change
From the AECO industry several options to make our planet a better place: for example, BIM. According to Ian Sutton, associate director of CBRE Building Consultancy, innovations of this type of methodology used to calculate all the information needed to design a building before construction so that we can make a more sustainable and intelligent approach. Some of its main advantages are:
• Greater decision – making: the ability to generate several designs on the same model allows a comparison to real time what is the best option for each building. To this we also add the data analysis tools such as sunlight, temperature or terrain conditions, serving architects.
• Better analysis: BIM works with 3D models, which help architects to have a much more detailed and complete design of each element, so quantities analysis and conflict detection may be carried out more effectively. This makes important decisions can be taken before construction of the building that save time, effort and money.
• Quick and easy access to information: the collaborative BIM principle is basic for the interoperability of project workers. All information is stored in a common cloud hosted system and to which each of the parties involved in the project can modify and add new items.
• Control lifecycle of the building: with all the digitized data in the cloud, it is easier to control the lifecycle of a building and the waste it generates.
ITWO, the future city of RIB
RIB ITWO has devised a smart city designed with BIM methodology based on the principles of lifelong learning and healthy aging. Its main philosophy is to bring together different generations and cultures to create a space that responds to the needs of modern life at all levels, both personally and professionally.
This process part of a virtual model that will be the basis for 3D BIM, in which all parties can analyze the design and choose which is the best choice for every need physical model. Something similar happens in Seoul, where users have access to the municipal platform called Sharehub , where share how to make cities a reasonable and sustainable living space.
Sustainable and economic initiatives
Knowing the characteristics of our city will allow us to be much more efficient, sustainable and environmentally care. In the case of Siemens, which has created the most economical light in the world that prevents more than 6,000 of harmful carbon emissions per year, significantly reduces pollution once implanted.
Another option is to bet on renewable energies. The Solar Impulse II is the first aircraft powered only by solar energy trying to circumnavigate the world. The device makes no noise, does not pollute and is a revolution in the field of aviation.
The Solar Impulse II, piloted by Bertrand Piccard its creator, departed on 28 June 2015 in the Japanese city of Nagoya and April 25 landed in the city of San Francisco. Your next destination is New York and Europe.
Another philosophy, along with BIM, which can help us turn our city into a more sustainable space is the LEAN because it creates value for the customer and helps reduce waste during the production process.
Its methodology is born in the workshops of Toyota in the 60s and is based on five pillars: organizing, sorting, cleaning, standardization and habit.
Though still an unknown philosophy, there are many cities that are trying to reduce emissions and promote sustainable attitude: Hamburg have banned the use of plastic in the buildings of government agencies in Milan and France companies pay workers who come their working positions bicycle and Oslo is working to prevent cars driving into the city center from here to 2019.
Meanwhile, in Copenhagen “green roofs” are already mandatory in all new buildings whose ceilings with a temperature of 30 degrees. This initiative helps reduce air temperature and absorb up to 80% of rainwater.
