LIBRARY // MEP COORDINATION

MEP Coordination in Data Centres

In a data centre, the MEP systems are the building's main job, not a supporting act.

Data centres are dominated by MEP systems. Their main purpose is to power and cool IT equipment reliably. Architecture, structure and MEP must be closely coordinated, as services drive the building's form and layout.

Power

Data centres need large amounts of power, delivered reliably. Typical systems include:

• Utility connections and substations
• Generators for backup power
• Uninterruptible power supplies
• Power distribution to racks

These need significant space, structural support and fire protection.

Cooling

IT equipment produces heat that must be removed continuously. Cooling approaches include:

• Air cooling with computer room air handlers or units
• Hot and cold aisle containment
• Liquid cooling for high-density equipment
• Free cooling where climate allows

Cooling systems drive plant space, roof equipment and pipe routes.

Redundancy

Data centres are designed for reliability, often with redundant equipment and distribution paths. Redundancy levels, sometimes described using frameworks such as the Uptime Institute's Tier classifications or TIA-942 ratings, affect how much equipment and space are needed.

Raised floors and overhead distribution

Some data centres use raised floors for air or cabling, while others use overhead distribution on slab. The choice affects floor-to-floor heights, structure and coordination.

Containment and layout

Rack rows, aisles and containment systems need coordination with lighting, fire detection and suppression and cable trays above.

Fire protection

Data centres often use specialised fire protection, such as gas suppression or pre-action sprinklers, along with early warning smoke detection. These affect room sealing and pipework.

Structural loads

Racks, batteries and plant can be heavy. Coordinate loads with the structural engineer.

Security

Physical security affects access routes, entry points and perimeter design.

Separation of systems

Redundant power and cooling paths often need physical separation to avoid single points of failure.

Expansion

Many data centres are built in phases. Plan for future capacity in plant, routes and space.

Commissioning

Data centres undergo extensive commissioning to verify that systems work under different scenarios.

Architecture's role

Architects coordinate the building envelope, layout, access, security and integration of services, often working closely with specialist engineers.

Coordinate with IT layouts

Rack layouts, power densities and cooling approaches depend on the client's IT plans. Get this information early and plan for changes, because IT equipment evolves faster than buildings.

Plan maintenance routes

Equipment needs replacing without disrupting operations. Plan routes and space for replacing large equipment, such as UPS units and chillers, while the facility stays live.
