Environmental Impact of Buildings: How to Calculate and Communicate It

The architecture and construction sector is undergoing a profound transformation, driven by the need to design buildings with a low environmental impact. Understanding, measuring, and communicating the impact of buildings is no longer merely an ethical choice, but a fundamental technical requirement demanded by international regulations and modern certification protocols.

In this article, we will explore the methodologies used to assess, manage, and transparently mitigate the ecological footprint of buildings, helping to protect projects from the risk of greenwashing.

How Do Buildings Impact the Environment?

The environmental impact generated by buildings is among the most significant on a global scale, as it affects ecosystems through various stages and mechanisms. According to the European Environment Agency (EEA), the construction sector accounts for approximately 30% of total material consumption in the European Union and represents one of the main sources of waste. This information is reported in the publication Addressing the Environmental and Climate Footprint of Buildings.

The environmental impact of a building is primarily manifested in three phases:

  • Extraction and Construction
  • The EEA reports that approximately one-third (33%) of all materials extracted and used within the European Union are absorbed by the construction sector. The extraction of raw materials and their transportation generate substantial quantities of greenhouse gas emissions.
  • Operational Phase
  • The daily use of buildings accounts for 42% of Europe’s energy consumption and 35% of greenhouse gas emissions, largely driven by heating, cooling, ventilation, and lighting systems.
  • End-of-Life and Land Consumption
  • Building demolition generates the largest waste stream by weight within the European Union. Furthermore, land occupation and soil sealing alter surrounding ecosystems, impacting water cycles and local biodiversity.

How Is the Environmental Impact of a Building Calculated?

Conducting an accurate assessment of a building’s environmental impact requires quantifying greenhouse gas emissions through Carbon Footprint calculation, an essential indicator based on internationally recognized frameworks such as the GHG Protocol and ISO 14064. These standards enable objective and transparent environmental evaluation.

The primary tools and methodologies used for this purpose include:

Life Cycle Assessment (LCA)

Life Cycle Assessment is the scientific foundation for calculating emissions. LCA evaluates the overall environmental impact of a product or building throughout all stages of its life cycle, from raw material extraction through manufacturing, use, and final disposal.

Environmental Product Declaration (EPD)

Particularly important for construction materials, an EPD is a third-party verified document that translates Life Cycle Assessment data into transparent and comparable environmental information, including indicators such as Global Warming Potential (GWP).

EPD data are essential for earning credits within sustainability certification systems.

 

The New UNI 11973:2025 Standard and ISO Standards

Recently introduced, UNI 11973:2025 provides updated and specific guidelines on how to calculate the contribution of buildings to sustainability performance. It complements established international standards such as ISO 14064 for emissions management and ISO 50001 for energy management systems, the latter also being adopted within Artigo’s production facilities.

EPD: Distinguishing Recycled Content from Renewable Content

Recycled Material

Recycled material originates from pre-consumer or post-consumer waste streams (for example, calcium carbonate derived from marble processing waste) that are reintroduced into production cycles, reducing the need for virgin resource extraction.

Renewable Material

Renewable material comes from natural sources capable of regenerating within a relatively short period of time, such as natural rubber obtained from rubber trees.

Clearly documenting these percentages within Environmental Product Declarations ensures complete transparency for designers, architects, and facility managers.

Why We Are So Proud of the “Back Side” of Our Flooring

The incorporation of recycled and renewable materials requires significant technological innovation.

While many resilient flooring products are homogeneous, meaning they consist of a single material layer throughout their thickness, Artigo has adopted a heterogeneous two-layer technology.

This technical solution makes it possible to incorporate high percentages of recycled material directly into the “back side” of the flooring—the lower layer—while ensuring excellent acoustic insulation, impact absorption, and a high level of sustainability.

At the same time, it preserves the aesthetic versatility, design freedom, and long-term durability of the upper wear layer.

How Can the Environmental Impact of a Building Be Reduced?

Reducing the carbon footprint of a project requires a holistic vision from the earliest design stages.

Creating low-impact buildings involves adopting an integrated approach that combines environmental performance, efficiency, and occupant well-being.

Design for Disassembly

To address the enormous volume of construction waste generated at the end of a building’s life cycle, sustainable architecture increasingly focuses on designing buildings whose components—including flooring systems—can be easily dismantled, separated, and recycled, thereby supporting a genuine circular economy.

Adoption of Green Building Protocols

Designing according to international certification frameworks, or following emerging approaches such as the Green Plus Building model developed by the University of Milano-Bicocca, maximizes environmental performance while ensuring high standards of comfort and well-being.

Selection of Sustainable and Healthy Materials

Giving preference to products equipped with Environmental Product Declarations and compliant with Minimum Environmental Criteria (CAM) is essential.

In innovative companies such as Artigo, this commitment translates into the development of flooring manufactured with bio-attributed rubber, incorporating recovered materials and ensuring extremely low Volatile Organic Compound (VOC) emissions.

These performances are certified by internationally recognized organizations such as Blauer Engel and Greenguard Gold, significantly improving indoor air quality.

Passive and Active Energy Efficiency

The use of high-performance insulating materials, intelligent shading systems, and the integration of renewable energy sources contributes to the development of nearly Zero Energy Buildings (nZEBs).

Durability as an Environmental Parameter

A sustainability-oriented design strategy should prioritize longevity, reducing the need for future renovations and limiting the consumption of additional resources and materials over time.

Renovation of Existing Building Stock

Consistent with EEA recommendations, prioritizing intelligent renovation over new construction is crucial for reducing land consumption and minimizing emissions associated with construction activities.

Choosing partners and materials that guarantee rigorous measurement methods and transparency is the first step toward creating efficient, healthy, and future-ready spaces, transforming regulatory requirements into genuine opportunities for strategic development.

ROI, Greenwashing, and Carbon Storytelling

Investing in sustainability is not only a way to protect the environment; it also generates a clear economic return on investment (ROI).

Green buildings benefit from what is commonly known as the “Green Premium”: they achieve significant reductions in operating and maintenance costs, increase their market value, and enjoy preferential access to financial incentives and funding opportunities.

However, the value generated by sustainability initiatives must be communicated correctly.

As highlighted by the international architecture firm Gensler, the ability to develop effective Carbon Storytelling has become an essential competency.

This narrative approach transforms complex technical data—such as the Global Warming Potential (GWP) values reported in Environmental Product Declarations (EPDs)—into meaningful stories that clearly illustrate tangible benefits for both communities and the environment.

Grounding Carbon Storytelling in rigorous scientific data provided by tools such as Life Cycle Assessment (LCA) and Environmental Product Declarations (EPDs) represents the most effective safeguard against greenwashing.

Communicating sustainability through verifiable certifications builds trust among stakeholders, encourages responsible investment decisions, and transforms regulatory compliance into a powerful competitive advantage.

The Role of SBTi Validation

This is where SBTi Validation (Science Based Targets initiative) comes into play.

Promoted by international organizations including the United Nations Global Compact and the World Wildlife Fund (WWF), SBTi certification verifies that a company’s emissions reduction targets—covering Scope 1, Scope 2, and Scope 3 emissions—are scientifically aligned with the objectives of the Paris Agreement, particularly the goal of limiting global warming to 1.5°C.

Artigo has recently obtained this rigorous validation for its decarbonization plan through 2031.

For architects, designers, and facility managers, choosing business partners certified by SBTi means incorporating materials into their supply chain whose “carbon story” is supported by unquestionable data and a concrete commitment to global climate action.

Design the Future Responsibly

Choosing sustainable materials, rigorously measuring their environmental impact, and communicating the results transparently are the first steps toward creating healthier spaces that are prepared to meet the climate challenges of the future.

By doing so, regulatory requirements are transformed into a genuine competitive advantage.
