Lighting modernization in the technological process area

The modernization of lighting in a construction industry plant showed that even without major investment outlays, significant results can be achieved. Through simple measures such as using natural light, installing motion sensors, or repositioning fixtures, the company reduced energy consumption by more than 103 MWh annually and gained an additional benefit in the form of White Certificates.

The challenge

In many companies, a significant potential for electricity savings lies in the area of lighting. These are often low-cost measures, based on good organizational and technical practices, which make it possible to reduce energy consumption without costly investments in new infrastructure. In a production plant from the construction industry, an analysis of the lighting system was carried out, which showed a potential reduction in energy consumption of more than 100 MWh per year.

Our approach

The DB Energy audit team thoroughly analyzed the lighting conditions in the production hall, taking into account both the technical parameters of the installation and the organization of the plant’s work. A practical approach was crucial – identifying areas where light was used inefficiently, while at the same time adjusting solutions to avoid reducing comfort and work safety. Recommendations included both technical and educational measures, enabling lasting changes in the way lighting is managed.

Solution

DB Energy engineers implemented a set of simple yet effective measures:

cleaning and repairing roof skylights, which increased the use of natural daylight,
training employees on good lighting practices,
installing motion sensors where the type of fixtures allowed – eliminating unnecessary lighting of unused areas,
repositioning selected lighting fixtures, which improved working conditions while reducing energy consumption,
additional organizational measures, supporting the optimal use of light.

Effects

Thanks to the measures taken, annual electricity consumption was reduced by 103.564 MWh, which translated into tangible cost savings. The plant also gained the opportunity to obtain White Certificates, confirming the effectiveness of the actions and providing an additional source of financial benefits. It is worth noting that most of the applied solutions were cost-free or low-cost, making the investment deliver a very quick return.

Conclusions

This project shows that improving energy efficiency does not always require large investment outlays. Even simple measures – such as better use of daylight or automation of lighting – can bring significant results. Involving employees in the process through training and building energy awareness further increases the durability of the achieved effects. The example of the construction plant confirms that well-chosen good practices are an effective way to reduce costs and improve working comfort.
