Comprehensive Ventilation
+ Cooling Solutions

Energy savings depend on building airtightness and operating hours. In well-sealed buildings, MVHR can significantly reduce heating demand by recovering waste heat from exhaust air, lowering overall HVAC energy consumption and improving EPC ratings.

Yes. Continuous filtered ventilation reduces CO₂ levels, Volatile Organic Compounds (VOCs) and airborne contaminants. This supports occupant wellbeing, productivity and compliance with workplace ventilation standards.

Routine filter changes (typically every 3-6 months), annual inspection of heat exchangers and fans, and periodic airflow balancing. Planned preventative maintenance (PPM) ensures sustained efficiency and protects SFP (Specific Fan Power) performance.

Evaporative cooling is most effective in large, open-plan environments such as warehouses, manufacturing facilities, logistics hubs and workshops. It is especially suited to spaces with high heat gains or frequent air changes.

No, not always.

Evaporative cooling systems can operate either as ducted or direct-to-space (standalone) units. In large warehouses or manufacturing environments, roof-mounted direct units often discharge cooled air straight into the space with minimal ductwork.

Where zoning, controlled air distribution or integration with existing HVAC systems is required, ductwork may be specified. The level of ducting depends on building layout, airflow strategy, occupancy patterns and whether the system is supplementing or replacing existing cooling infrastructure.

Operational costs are generally low due to the system’s simple mechanical design. Evaporative cooling primarily uses fans and water pumps, resulting in significantly lower electrical demand than compressor-based cooling systems.

Key cost considerations for facilities managers include:

• Electricity consumption (fan motors and pumps)
• Water usage, which varies by climate and operating hours
• Water treatment and hygiene management to maintain system efficiency
• Routine maintenance, including pad replacement and seasonal servicing

When assessed on a lifecycle basis, evaporative cooling offers a cost-effective solution for large-volume spaces with long operating hours.

Efficiency can be improved through a combination of optimisation and maintenance. This includes refining controlss and sequencing to match demand, maintaining correct refrigerant charge, and using variable speed drives (VSDs) to reduce part-load energy use.

Yes, in many commercial, high-rise and multi-occupancy buildings. Requirements are set out in Approved Document B, alongside BS EN standards such as BS EN 12101. These systems are critical for maintaining safe escape routes and supporting firefighting operations.

Regular testing is essential to ensure reliability in an emergency. Weekly functional checks are typically required to confirm system readiness, with more comprehensive periodic inspections and servicing carried out in line with fire safety regulations, system type and maintenance contracts.

Yes, smoke control systems can interface with a BMS for status monitoring, alarms and fault reporting. However, they must remain fully independent and fail-safe as life-safety systems, ensuring compliance with fire regulations and preventing any compromise to emergency operation.
