Facing Global Warming with Innovations in Civil Construction

The rising heat waves, exacerbated by phenomena such as El Niño and climate change, have led to record temperatures in Brazil, surpassing 44.8ºC. In light of this challenging scenario, the Civil Construction Industry emerges as a fertile ground for innovations aimed at sustainability and thermal comfort. Thermal insulators are being increasingly adopted to reduce the sensation of heat, consequently decreasing the dependence on appliances like air conditioners, which raise energy consumption.

Emerging Technologies and Materials in Sustainable Construction

Various innovative alternatives are emerging in the market to meet this need for environmental cooling without impacting the energy bill. Among them, the following stand out:

EPS Isopor (Expanded Polystyrene): This material, composed of 98% air and recyclable, is recognized for its effectiveness in thermal insulation, offering protection and lightness to constructions.
Glass Wool: A high-performance thermal insulator, glass wool is versatile and can be applied in slabs, ceilings, and walls, significantly contributing to more comfortable and energy-efficient environments.
PIR and PUR Boards (Polyurethane and Polyisocyanurate): These thermal insulating boards, made of rigid foams, have excellent thermal resistance properties and low moisture absorption, making them ideal for civil construction.
Cellular Concrete Blocks and Special Ceramic Bricks: With thermoregulating properties, these materials are effective in retaining heat, providing cooler indoor environments.

The Role of the Private Sector and Science in the Pursuit of Sustainability

Beatriz Luz, from Exchange 4 Change Brazil, and the Brazilian Association of Metallurgy, Materials and Mining (ABM), highlight the importance of developing these materials in the global context of the climate crisis. World Bank reports emphasize the urgency of transitioning to sustainable practices, stressing the crucial role of the private sector and public policies in this change. The involvement of technical committees from ABM and support for scientific development have been fundamental in fostering the circular economy and sustainability across various sectors, including civil construction.
