Generators for Office Buildings

Product Description

In an office building, a power outage can simultaneously affect business operations, IT infrastructure and shared building services. Even if laptops continue running on battery power, network equipment, lighting and technical systems depend on an available power source. Industrial backup generators support priority loads and help maintain operations during utility outages.

What does the generator power in an office building?

The configuration is determined by the services that the building manager and tenants want to keep available. Having a generator does not automatically mean that every space and piece of equipment in the building receives backup power.

Depending on the design, supported loads may include:

• IT and communications infrastructure: local servers, network equipment and telephone systems.
• Priority work areas: dedicated circuits for equipment needed to continue business operations.
• Lighting and security: selected circuits in offices and common areas, video surveillance and access control.
• Building services: pumps, ventilation and air conditioning for areas included in the backup solution.
• Building management systems: controls and equipment used to monitor building services.

In multi-tenant buildings, each tenant’s allocated capacity, supported circuits and outage priorities must be clearly defined. This allows businesses to align their continuity plans with the building’s actual capabilities.

How does the generator work with UPS systems?

When utility power fails, automatic controls can initiate generator starting and transfer the loads once electrical parameters have stabilised. For equipment that cannot tolerate this interruption, UPS systems maintain power during starting and transfer.

The generator and UPS fulfil complementary roles: the UPS provides immediate continuity for connected loads, while the generator enables longer periods of operation. Their compatibility and sizing must be assessed together, including the power required to recharge the batteries.

Maintaining power to local equipment does not, by itself, guarantee internet connectivity or access to external applications. These also depend on the infrastructure of communications and service providers.

How is the backup solution sized?

Calculations start with the loads that will operate simultaneously on backup power. The assessment considers power demand, motor starting requirements, interaction with UPS systems and the load connection sequence. Connecting larger systems in stages can reduce the demand placed on the generator.

Requirements must be reassessed when tenants change, occupied areas expand or equipment is added. A configuration suited to the building at its opening may need adjustments as its load profile changes.

Generator placement must account for noise, vibration, ventilation and exhaust routing, particularly near windows and air intakes. Access for servicing and refuelling is equally important for long-term operation.

Testing and maintenance coordinated with building management

Periodic checks must include generator starting, automatic transfer and the supply of circuits specified in the design. Tests are planned with the building manager and tenants to control their impact on business operations.

Preventive maintenance and alarm monitoring help identify problems before an actual outage occurs. Runtime is determined by the supported load, required operating duration and refuelling arrangements.
