How to optimise the energy efficiency of buildings with BIM?

On Tuesday 15 November 2022, the number of people on Earth passed the eight billion mark. According to UN estimates, this curve will continue to climb until it reaches a peak of 10.4 billion people in the late 2080s. 

With more and more people migrating to the same regions, and more and more people living in the same cities in the coming decades, the challenge of preserving the health of our planet is therefore considerable. 

What can be done about it? BIM, Building Information Modeling, is already helping to improve the energy efficiency of our buildings and cities on the environment, and will continue to do so in the coming years. A solution for sustainable construction.

Let’s find out how this methodology will help reduce our environmental impact.

BIM : a solution to reduce environmental impact

So if BIM is becoming widespread in the construction sector, how can this methodology help optimise the energy efficiency of buildings? 


First of all, using BIM allows for the collection and storage of information and the monitoring of consumption in real time. By keeping track of the materials used, digital project management tools are very effective in gaining more control over the negative impacts of a construction project. 


The construction industry uses significant amounts of natural resources to manufacture materials. And much of this is often lost, wasted, in project redesign, inaccuracies or overestimates.  According to the French Building Federation, the sector generates around 46 million tonnes of waste per year! 51% of building waste comes from demolition sites, 36% from renovation and 13% from new construction.

Careful monitoring of each operation, in real time and using BIM, would greatly reduce this waste. Indeed, better quality in buildings would mean fewer mistakes. And thus, fewer demolitions and buildings that would last longer over time.
