Structures with low carbon emissions have been an emerging topic in the civil construction scene, aligning with the global urgency for more sustainable solutions. These structures are designed to minimize environmental impact through a reduced carbon footprint, both in construction and operation. O Global Status Report 2020 for Buildings and Construction from the UN Global Alliance for Buildings and Construction, shows that the need to adopt greener practices in construction has become a direct response to global climate goals, aiming to substantially reduce greenhouse gas emissions by 2050.
According to the website ArchDaily, the construction sector is one of the largest contributors to carbon emissions, with energy used for lighting, heating and cooling buildings accounting for approximately 28% of global carbon emissions. Another 11% comes from embodied carbon, which includes emissions related to building construction, transportation of materials, manufacturing, installation and end-of-life impacts. Carbon-neutral buildings, therefore, are not only an environmentally friendly choice, but also an imminent necessity to achieve global climate goals.
However, achieving carbon neutrality in buildings presents significant challenges, mainly in terms of costs. The initial investment in innovative technologies and materials tends to be higher compared to traditional construction methods. For example, photovoltaic panels, advanced insulation systems, energy-efficient HVAC systems, and other sustainable technologies can significantly increase upfront costs. However, it is important to consider that although initial costs are higher, long-term operating costs can be substantially lower due to energy efficiency and lower carbon emissions.
In addition to economic challenges, carbon-neutral buildings present significant opportunities, both environmentally and socially. They can generate higher revenues as tenants are willing to pay more for space in environmentally friendly buildings, with reports showing rent increases of 6% and sales increases of 8%. Furthermore, the transition to carbon-neutral works has the potential to create millions of jobs, with Europe and the United States expected to see a substantial increase in jobs in this area.
Anicio Moreira Cabral, Managing Director of Novemp, a company specializing in electrical systems and engineering solutions, highlighted the importance of this transition: “The adoption of carbon neutral buildings is not only a response to environmental demands, but also a significant economic opportunity. Companies like Novemp, which provide electrical panels and integrated solutions for civil construction, play a crucial role in supporting this movement, driving technological innovations and contributing to the green economy”.
In short, carbon neutral buildings represent a crucial step towards a more sustainable future. While the challenges, especially in terms of initial costs, are significant, the opportunities in terms of environmental sustainability, economic benefits and job creation are immense. As society moves to meet the demands of a low-carbon world, the construction of carbon-neutral buildings will increasingly be seen not just as a choice, but as a necessity.
