23.4 % Savings with lighting controls

This is a modelled estimate; actual savings depend on your operation.

Total investment excluding VAT ≈ 500,000 CZK
Simple payback including installation ≈ 4 years

Indicative estimate excluding VAT for prepared lights and straightforward installation. The final price will be confirmed in a quotation.

How we calculate

Assumes previously uncontrolled lights suitable for controls. Savings from LED replacement are excluded.

Application Default hours/year Estimated light energy reduction
Industry & warehouses 4,000 25 %
Offices 2,500 30 %
Retail 4,380 15 %
Street lighting 4,100 30.4 %

Annual consumption (kWh) = number of lights × power per light (W) × annual lighting hours ÷ 1,000. We assume the lights run at full power.

Savings are estimated by application; street lighting uses a modelled Savee dimming profile. The result is indicative and depends on actual use and the controls the lights support.

We deduct estimated controls consumption: 1 W per light and 20 W for a server, powered continuously all year. We multiply the saved kWh by the electricity price.

Payback = system cost including installation / annual electricity savings. We assume a constant electricity price and exclude maintenance, servicing and financing. All amounts exclude VAT.

Further recommendations

Consider replacing older lights with LED luminaires. Potential savings from replacement are not included in this estimate.

We can also assess potential servicing and maintenance savings from remote monitoring. These benefits are not included in the calculator.
