Energy Savings With Short Payback in Commercial Spaces

Key Results:

• 33,100 kWh saved per year

• 7,400 kg CO₂ emissions reduced annually

• £8,200 saved each year

• 60% reduction in fan energy consumption

• 1-year payback period

The Challenge

Energy prices keep rising, but most ventilation systems still run the same way they did 20 years ago - constant speed, all day, regardless of actual demand.

For commercial buildings with catering facilities, this creates a significant and controllable cost. But many energy-saving solutions require expensive system overhauls with long payback periods that don't make financial sense.

Our client needed a different approach: meaningful energy reduction without ripping out existing infrastructure.

The Solution

Cheetah demand-controlled ventilation integrates with existing EC fans, inverter drives, and Building Management Systems. No major retrofit required.

The system monitors real-time activity and adjusts fan speeds automatically - delivering full ventilation when needed, reducing energy consumption during quieter periods.

This means substantial savings without the capital expenditure and disruption of a complete system replacement.

The Results

Single site performance:

• 60% reduction in fan energy consumption

• £8,200 annual savings

• 33,100 kWh saved per year

• 7,400 kg CO₂ reduced annually

• Payback achieved in just 1 year

Across four commercial installations (British American Tobacco, Eaton Mission Systems, National Grid Training Centre, and UAL St Martins):

• 132,700 kWh saved annually

• £33,190 total annual savings

• 29.8 tonnes of CO₂ reduced each year

Why It Works

Cheetah turns ventilation from a fixed cost into an optimised system. By matching fan speeds to actual demand rather than running at maximum constantly, the technology delivers immediate savings that compound year after year.

For commercial spaces with existing ventilation infrastructure, this approach provides proven ROI without the risk and expense of complete system replacement.

Following these successes, we've continued installations in major commercial buildings including BMW Oxford, Société Générale, and Oracle -

helping businesses achieve energy efficiency goals while working seamlessly with their existing systems.
