How exactly do you or your project contribute to making STRABAG more sustainable?
The electricity produced by our PV system is 100% sustainable and directly supplies our construction site with green energy every day. This is how we use the hours of sunshine to build our structure. On a good weather day, our construction workers are more motivated, and our cranes and equipment work more sustainably. By measuring electricity consumption using smart meters, we can visualise and evaluate the electricity consumption curve of a large construction site for the first time and draw conclusions from it.
As a result, we have found out that in winter the biggest electricity consumers are not the cranes or construction equipment, but the electric convectors in our containers. This awareness, combined with user behavior, enables us to reduce our consumption and thus save energy and costs.
With several hundred thousand lighting hours of the container lighting and the crane spotlights, the switch to LED lighting fixtures pays off. The energy savings per diffuser luminaire in our container were 45%, and 65% for an LED crane spotlight. These adaptations required little effort and can be easily implemented on any construction site.
