Low energy and maintenance costs for lighting are especially important in training facilities. While municipal sponsors of training facilities usually seek to avoid increased initial investments due to a scarcity of budget resources, an overall economic efficiency calculation for refurbishments of old lighting installations is the best argument for sensible capital expenditure, which pays off within a short period of time due to energy and maintenance cost savings. An overall cost calculation provides ample proof (see chapter “Light and economic efficiency”).
The high luminous efficacy of LED luminaires as well as bright, clean room equipment and simple operation of the installation in terms of maintenance reduce lighting costs.
Expedient use of daylight also contributes to this effect (see chapter , “Light and the environment”).
Energy-saving lighting systems using the latest technology in combination with a light management system that provides presence and daylight-dependent lighting regulation often only require less than 20% of the energy older installations consume.
