Energy saving
Do you know that return on investment in lighting may be less than 3 years?
- Do you know that up to forty percent from the total costs of power consumption is spent on lighting?
- Do you know that by optimizing the illuminating system you may achieve up to 70% of decrease in consumption of power for lighting?
- Do you know that LED technology lights may also replace a relatively new illuminating system with fast return on investment?
We will prepare a study of energy savings and return on investment for you.
How can we help you to achieve savings?
- We will carry out an analysis of the existing state of the illuminating system
- We will propose appropriate technology for new illuminating system
- We will make energy balances and calculate return on investment
- We will provide a project support
- We will carry out a new illuminating system
What risks are involved? How to proceed?
- Consult us where it is suitable to use LED lights. LED lights are not appropriate for all spaces yet.
- Unfair companies offer tendentiously proposed projects with distorted results. Be circumspect: some companies compete with each other in data concerning rate of return!
- Technical quality of lights is not the same. Unfair companies deliver non-quality LED sources and lights - in case of unresolved temperature management of LED lights, LED life-time is significantly shortened.
- Be careful with the choice of a partner for savings in lighting. References, company history, financial background and stability, these are important indicators. It could happen to you that there would be no person to deal with a possible complaint.
