Why it matters for the HVACR and construction sectors

Life Cycle Assessment (LCA) has quickly become one of the most trusted scientific methods for understanding the environmental implications of materials and building systems. As Europe intensifies its decarbonisation goals, both the construction and HVACR sectors face rising expectations for transparent, standard based sustainability reporting. Regulations, tenders, and buyers increasingly ask manufacturers and designers to justify choices through verifiable data rather than marketing claims, placing methodologies like LCA at the centre of modern decision making.

Regulatory and market pressures are accelerating the adoption of LCA across HVACR and construction. At EU level, policies such as the recast Energy Performance of Buildings Directive (EPBD), the Corporate Sustainability Reporting Directive (CSRD), and the Ecodesign for Sustainable Products Regulation (ESPR) are driving demand for verified life-cycle data at product level and across supply chains. In parallel, market frameworks such as LEED, BREEAM and other green building schemes, together with corporate ESG commitments, increasingly rely on Environmental Product Declaration (EPD) and LCA results to support design choices, procurement decisions, and sustainability claims.

What is a Life Cycle Assessment?

At its core, LCA evaluates how a product (goods or service) or building affects the environment throughout its entire existence: from raw material extraction all the way to end-‑of-life processing. This approach, grounded in the ISO 14040 and 14044 frameworks and supported in construction by the widely adopted EN 15804, allows professionals to understand not just how a product performs in use, but the full environmental burden associated with producing, installing, maintaining, and eventually disposing of it. For energy-related building products, including HVACR equipment, the general LCA rules are given by EN 50693 but not completely in contradiction to EN 15804. EN 50693 standard provides additional modelling rules for products whose environmental performance is strongly influenced by energy use, operational behaviour, maintenance, and, where applicable, refrigerants or other working fluids.

Why is LCA data important?

What makes LCA particularly powerful in the building context is the precision with which it can track environmental impacts, with EPDs widely adopted at product level, and whole building LCA and carbon footprint becoming the norm in both regulatory and voluntary landscapes. Carbon footprint remains the best-known indicator, but LCA extends far beyond that, considering water scarcity, particulate matter emissions, resource consumption, and even flows related to circularity and waste. All these indicators are usually expressed relative to a clearly defined “functional unit,” such as the performance of a building or product system over a given lifespan. This should theoretically ensure that results can be meaningfully compared and integrated into procurement processes, ecolabels, and sustainability frameworks.

The evolution of environmental data

EPDs are becoming the cornerstone for evaluating and tracking environmental impacts in buildings, a sector that, according to the International Energy Agency (2022), is responsible for nearly 40% of global annual emissions. Hence, accurately tracking the environmental impacts arising from construction materials and the building's use phase should be imperative at the planetary health level.

In recent years, sustainability thinking has broadened further with the emergence of Life Cycle Sustainability Assessment (LCSA), which extends the environmental scope of LCA by incorporating economic and social dimensions. This more holistic approach combines LCA with Life Cycle Costing, standardised (for the building sector) under ISO 15686-5 and EN 16627, and with Social Life Cycle Assessment, standardised in ISO 14075. When these three dimensions are evaluated together, stakeholders gain a more balanced understanding of the trade-offs between environmental impact, economic viability, and social value.

This broader perspective is becoming increasingly important because the HVACR industry within the building sector is expected to expand significantly in the coming decades, bringing with it substantial environmental pressures. While buildings account for nearly 40% of global greenhouse gas emissions, they also play a crucial role in improving quality of life, safety, and social wellbeing, factors in which HVACR equipment plays a very important role. LCSA therefore helps project owners and policymakers determine whether a project is not only feasible but genuinely beneficial for communities and the environment.

Evaluating the environmental, social and economic performance of HVACR products

A key theme emerging from LCA practice is the role of sustainability indicators to provide the backbone of transparent environmental evaluation. Yet, their selection can vary depending on the scope, standards applied, and the stakeholders involved. For construction products, environmental KPIs are often aligned with the impact categories featured in EPDs, which usually follow EN 15804 rules and offer a harmonised, publicly accessible way to communicate environmental data. For HVACR products on the other hand, sustainability KPIs have been so far linked to energy efficiency mainly. However, given the demand from clients/consumers for more environmentally aligned data for sustainability reporting or for construction rating schemes, KPIs such as carbon footprint, water footprint, cumulative energy demand seem to be gaining momentum.

Economic indicators, by contrast, follow the structure of Life Cycle Costing, capturing operational and maintenance expenses, replacement cycles, and total cost of ownership. Social indicators remain more flexible, adapting to the product’s characteristics and its potential effect on occupants, workers, communities, and supply chain actors. This adaptability is especially relevant in buildings, where many materials or equipment, such as insulation, or HVACR components can influence different and multiple groups.

Translating these sustainability considerations into the day-to-day reality of construction and HVACR requires a clear understanding of how environmental, social, and economic impacts materialise throughout the life cycle. Environmental effects may stem from refrigerant leakage, embodied carbon in insulation or ducting, but mainly from the energy required to operate equipment over decades. Some social impacts may touch on indoor air quality, accessibility, worker safety, or the effect of construction operations on neighbouring communities. Economic performance, meanwhile, depends not only on upfront costs but on long term durability, maintenance schedules, replacement intervals, and energy consumption.

To conclude

While LCA offers a powerful framework, several challenges remain. Data availability and quality can hinder accurate assessments, especially in complex supply chains. The digitisation of EPDs, the emergence of Digital Product Passports, and advances in Building Information Modelling (BIM) can support more accurate sustainability reporting and help fix the data problem. As regulations converge and market expectations rise, companies that commit early to transparent lifecycle methodologies will be better positioned to demonstrate leadership and compliance.

Ultimately, LCA framework is reshaping how the construction and HVACR industries define sustainability. They replace generalised claims with verifiable data and offer a foundation for designing, selecting, and promoting products that contribute meaningfully to Europe’s climate and social objectives. For manufacturers, consultants, and designers, adopting these practices is no longer optional, it is essential for remaining competitive, credible, and aligned with the sector’s future.
