BREEAM Pass

Data centers must establish and document a formal environmental management system (EMS) meeting ISO 14001 principles or equivalent, covering energy, water, waste, and emissions monitoring with defined responsibility structures.

This requires appointment of an environmental management representative, establishment of environmental policies specific to data center operations, and quarterly reporting of key performance indicators including PUE (Power Usage Effectiveness), water consumption metrics, and waste diversion rates.

The EMS must include procedures for regular audits of cooling systems, power distribution efficiency, and IT equipment lifecycle management.

BREEAM Pass mandates installation of Building Energy Management Systems (BEMS) with sub-metering capability to track energy consumption across distinct data center zones (cooling, IT equipment, power conversion, lighting, and ancillary systems).

Data centers must establish baseline PUE measurements, set reduction targets of minimum 5% improvement over 12 months, and maintain continuous monitoring with data granularity enabling identification of efficiency degradation.

Monthly energy audits must verify actual performance against benchmarks from comparable facilities, with documented corrective actions for underperformance.

When procuring new infrastructure components, materials, and equipment for data center operations, organizations must source a minimum 80% (by cost value) from suppliers meeting BREEAM-recognized responsible sourcing standards including FSC-certified timber, recycled content declarations, and embodied carbon assessments.

This extends to cooling systems, cable management infrastructure, structural components, and even server hardware, requiring suppliers to provide Environmental Product Declarations (EPDs) or equivalent third-party verified environmental data.

Data centers utilizing water-cooled systems or evaporative cooling must implement sub-metering to track consumption, establish baseline water usage intensity (liters per kilowatt-hour), and demonstrate minimum 10% reduction targets.

BREEAM Pass requires documentation of water source (mains, recycled, rainwater harvested), treatment protocols, and discharge quality monitoring.

Facilities must investigate alternative cooling technologies or water-efficient designs, with preference given to dry cooling systems or advanced analytics-driven cooling optimization.

Data centers must implement comprehensive waste segregation protocols achieving minimum 65% diversion from landfill across all waste streams (IT equipment, construction/operational waste, consumables).

This requires documented partnerships with certified recyclers for server decommissioning and e-waste management, separate collection streams for organic, packaging, and hazardous materials, and monthly waste tracking reports.

BREEAM assessors verify waste contractor credentials and audit disposal pathways to confirm actual diversion rates.

While data center computer rooms have specific thermal requirements precluding standard comfort criteria, BREEAM Pass requires that all office spaces, control centers, and occupied facilities meet Health & Wellbeing criteria including thermal comfort (within 2°C band during occupied hours), daylight access to minimum 95% of regularly occupied areas, and mechanical ventilation with CO2 monitoring.

Low-VOC paints and finishes must be specified in occupied spaces, and facilities must provide clearly documented emergency egress lighting and thermal refuge areas.

Data center sites must demonstrate commitment to reducing transport-related emissions through documented policies encouraging staff use of public transport, with evidence of proximity to transit (maximum 400 meters to nearest station or equivalent public transport access point).

Facilities must provide secure bicycle parking for minimum 5% of workforce capacity, designated low-emission vehicle parking spaces, and car-sharing scheme partnerships.

For geographically isolated facilities, documented shuttle services or remote work policies offsetting commute requirements satisfy transport requirements.

Data centers must implement controls preventing fugitive refrigerant leakage from cooling systems through quarterly inspections of sealed connections, maintenance of refrigerant inventory logs, and use of low-GWP (Global Warming Potential) refrigerants with documented phase-out schedules for legacy high-GWP substances.

Light pollution from external lighting must be controlled through installation of directional fixtures and timers preventing unnecessary illumination.

NOx and particulate emissions from on-site generation equipment must be monitored against baseline, with records demonstrating compliance with local air quality regulations and annual emissions reporting.
