Hot & Cold Aisle Containment Solutions

Introduction

Environmental Product Declarations (EPDs) and Environmental, Social, and Governance (ESG) reporting are becoming foundational elements in modern data centre construction and operations. 

As global clients and hyperscale operators push for transparency and sustainability, contractors and suppliers must demonstrate measurable environmental performance across their product lifecycle. 

For teams involved in hot and cold aisle containment, understanding how materials are assessed, declared, and reported is critical to aligning with client sustainability targets and corporate commitments such as net zero carbon goals. 

This section bridges the technical understanding of EPDs with the broader ESG frameworks that guide responsible procurement, reporting, and performance benchmarking. 

It continues the discussion from Section 11.2 on energy and carbon tracking, expanding from system efficiency to material and corporate accountability. 

By mastering these principles, containment professionals can help data centre clients achieve compliance with environmental standards while also strengthening their own corporate reputation and competitive edge in tenders.

‍

11.3.1 Understanding Environmental Product Declarations (EPDs)

An Environmental Product Declaration (EPD) is a verified, standardised document that quantifies the environmental impact of a product throughout its life cycle. 

It follows principles set by ISO 14025 and EN 15804, offering transparency about materials, production processes, transportation, installation, and end-of-life management. 

In data centre environments, EPDs are increasingly used for containment systems such as aluminium framing, polycarbonate panels, glass doors, and steel fixings.

‍

Key attributes of an EPD include:

• Life Cycle Assessment (LCA): 

Evaluation of resource extraction, manufacturing, transport, use, and disposal.

• Declared Unit: 

Defines the product measurement basis (e.g., 1 kg of aluminium extrusion).

• Environmental Indicators: 

Metrics such as Global Warming Potential (GWP), Ozone Depletion Potential (ODP), and Water Consumption.

• Verification: 

Independent third-party validation ensures reliability and comparability.

By reviewing EPDs during design and procurement, engineers and project managers can make data-driven decisions that reduce the embodied carbon footprint of their containment systems. 

For instance, choosing an aluminium supplier with a recycled content EPD may result in a 60 % lower GWP than one using virgin material. 

These decisions have both immediate sustainability impacts and long-term operational value, especially when data centres pursue certifications like BREEAM (Building Research Establishment Environmental Assessment Method) or LEED (Leadership in Energy and Environmental Design).

‍

11.3.2 Integrating EPDs into Data Centre Procurement and Design

Integrating EPDs into the early stages of procurement and design ensures alignment with the client’s environmental goals. 

During tender or RFP (Request for Proposal) phases, many operators now mandate EPD submission for major material categories, including metal framing systems, cable trays, and polycarbonate panels used in containment.

‍

A structured approach should include:

1. Specification Review: 

Ensure that all containment materials specified by design consultants are accompanied by valid EPDs or equivalent documentation.

2. Supplier Prequalification: 

Verify that selected vendors participate in recognised EPD programmes (e.g., The International EPD System, BRE Global).

3. Document Verification: 

Confirm that the EPD is third-party verified, current, and applicable to the correct product category.

4. Carbon Comparison: 

Evaluate multiple EPDs for similar products to select the lowest-impact option that still meets structural and fire safety requirements.

5. Digital Records: 

Maintain EPD files in the project’s document management system or BIM (Building Information Modelling) environment for traceability.

These processes not only support compliance but also prepare data for ESG disclosure and lifecycle cost analysis. 

When integrated correctly, EPDs can influence material selection, supplier engagement, and logistics decisions, ultimately reducing embodied carbon across the entire build.

‍

11.3.3 ESG Reporting Frameworks in the Data Centre Sector

Environmental, Social, and Governance (ESG) reporting refers to the systematic disclosure of a company’s sustainability performance, covering energy use, emissions, materials, and social responsibility. 

For data centres, ESG reporting is not just a compliance activity but a strategic necessity for investor confidence and client trust.

‍

Key reporting standards include:

• GRI (Global Reporting Initiative): 

Provides a globally recognised framework for environmental and social impact disclosure.

• SASB (Sustainability Accounting Standards Board): 

Defines sector-specific metrics, including energy intensity and materials management for technology infrastructure.

• TCFD (Task Force on Climate-related Financial Disclosures): 

Focuses on governance and risk management around climate impacts.

• CDP (Carbon Disclosure Project): 

Collects and publishes data on organisational carbon footprints and energy usage.

For containment-related operations, ESG reporting translates into measurable actions such as:

• Recording embodied carbon data from EPDs into the company’s ESG software.
• Tracking supplier diversity and labour compliance under the “Social” pillar.
• Demonstrating governance through robust QA/QC (Quality Assurance/Quality Control) and responsible procurement.

A mature ESG approach allows companies to showcase leadership in sustainability and opens doors to clients with strict environmental prequalification requirements, including global hyperscalers and colocation providers.

‍

11.3.4 Linking EPD and ESG Data for Performance Measurement

The connection between EPDs and ESG reporting lies in data integration. 

While EPDs provide product-specific metrics, ESG reports aggregate this information at an organisational or project portfolio level. 

Linking the two creates a powerful feedback loop where material choices directly influence corporate sustainability performance.

‍

Effective linkage can be achieved through:

• Centralised Data Systems: 

Using platforms such as ISO 14001 Environmental Management Systems (EMS) or digital construction tools like Autodesk Insight or One Click LCA.

• Carbon Accounting: 

Translating EPD data (e.g., kg CO₂ e per kg of material) into total project carbon emissions for Scope 3 reporting.

• Supply Chain Collaboration: 

Encouraging suppliers to submit verified EPDs and share material data in compatible formats (e.g., XML, Excel templates).

• Continuous Improvement: 

Using data trends to reduce embodied carbon over successive projects by favouring lower-impact materials.

By integrating EPD results into ESG reporting dashboards, organisations can demonstrate year-on-year progress, justify sustainability investments, and align with client reporting cycles. 

This alignment is increasingly demanded by investors, regulators, and data centre clients seeking transparent performance evidence.

‍

11.3.5 Regulatory and Market Drivers

Governments and industry bodies are tightening regulations to ensure environmental accountability. 

In Europe, the Construction Products Regulation (CPR) and the EU Taxonomy for Sustainable Activities both encourage the use of EPDs as evidence of responsible material selection. 

Similarly, the UK’s Building Regulations Part L and initiatives like the Net Zero Carbon Buildings Standard are pushing firms toward full material disclosure.

‍

Market drivers include:

• Client Sustainability Requirements: 

Large operators such as AWS, Google, and Microsoft require suppliers to align with their carbon reduction pathways.

• Investor Expectations: 

ESG performance influences access to capital and affects corporate valuation.

• Tender Competitiveness: 

Bidders demonstrating EPD-backed materials and ESG credentials often score higher in technical and commercial evaluations.

Understanding these drivers ensures that containment professionals not only comply with evolving standards but also remain competitive in a rapidly changing marketplace.

‍

11.3.6 Practical Application in Hot and Cold Aisle Containment

In practical terms, EPD and ESG considerations translate into material and process choices on site. 

‍

Examples include:

• Selecting recyclable aluminium with verified EPD data instead of non-certified alternatives.
• Using polycarbonate panels manufactured with renewable energy sources and documented low GWP values.
• Implementing modular containment systems designed for disassembly and reuse to support circular economy objectives.
• Recording material use in project carbon trackers linked to corporate ESG databases.

By embedding these practices, containment specialists contribute to tangible sustainability outcomes without compromising functionality, aesthetics, or fire safety performance. 

The focus moves beyond compliance to leadership, where each design and procurement decision becomes an opportunity to reduce environmental impact.

‍

With a clear understanding of how Environmental Product Declarations and ESG reporting underpin sustainable construction practices, the next step is to explore the practical tools and systems that enable consistent delivery. 

Section 12 examines the digital platforms, management software, and monitoring systems used throughout the data centre lifecycle. 

From BIM integration and QA tracking to commissioning tools and live monitoring dashboards, this next section bridges sustainability commitments with operational execution, ensuring that every action on-site aligns with measurable outcomes and continuous improvement.
