Payback periods calculation for light relamping project

Payback periods calculation for light relamping project

The old cost comparison model is based on the ‘blanket design’ approach. We light an entire room to a particular illuminance for a particular period of time – usually the whole working day. That only requires a simple bit of mathematics to translate the physical situation into a projected kilowatt-hour cost.

Payback periods for better (more expensive) technology could be worked against that model, but now we’re contemplating a high energy-cost future in a low-carbon environment that model no longer serves.

Lighting Calculations

Lighting calculations can initially seem quite simple to perform using today’s computer based calculation programs. But it takes an experienced lighting planner to make correct assumptions and premises, and also to interpret the results. Normally several adjustments have to be made before you receive an optimal result. It’s important to perform genuine calculations for your installation.
