The environmental benefit of modular building

In an era where sustainability is a top priority, modular construction offers a powerful solution.
Through efficiency, reusability, and significant reductions in CO₂ and nitrogen emissions, this method makes a substantial contribution to lowering the ecological footprint of the construction industry.

Up to 50% less CO₂ emissions

Studies show that modular construction methods generate 43–50% less CO₂ emissions on average than traditional construction. For example, a Canadian study reported a 43% reduction during the construction phase, while analyses by Daiwa House Modular Europe found reductions of up to 50%.

Up to 90% less construction waste

Building in a controlled factory environment minimizes waste. According to WRAP, waste can be reduced by as much as 90% compared to traditional construction, thanks to smart material usage and effective recycling management.

Reduced nitrogen emissions

Field measurements (via AERIUS) show that modular housing construction produces less than half the NOₓ emissions per m²—on average 16 g/m² compared to 36 g/m² in traditional methods—resulting in over 55% reduction.

Energy-efficient production facilities

Factories provide better insulation, more efficient energy use, and less need for on-site heating. Studies show that energy consumption during construction can drop by up to 67%. Additionally, modules protect the site from weather exposure, resulting in extra CO₂ savings during colder seasons.

Circular design and reuse

Modules are designed to be disassembled and reused, extending material life cycles and reducing demolition waste. Research shows that modular construction produces up to 75% less wood and gypsum waste than traditional methods.

Controlled build quality = less waste

Thanks to factory-based production, modules are built with precision. This significantly reduces errors and leftover materials—issues often encountered on traditional construction sites.
