At the construction site which will eventually become Berlin's new international airport, there are no dark corners as the lights of the terminal building burn 24/7, due to an inability to turn off the lights.
The project has been plagued by a series of setbacks, however this latest technological obstacle seems to be more bizarre than most.
According to SpiegelOnline, in a rare public appearance last week, Horst Amann, airport technical director, admitted: "It has to do with the fact that we haven't progressed far enough with our lighting system that we can control it."
Officials daren't officiate a completion date for the project for fear of missing yet another, as due to design glitches and concerns about safety - to name just a couple - the teams have already missed so many.
Rainer Schwarz, the airport's chief executive, was fired off the back of the failings in January and since Wilhelm Bender, former head of an airport in Frankfurt, declined the position at the beginning of February, little progress has been made in finding someone to helm the project.
While it may seem somewhat amusing that nobody can find a light switch in such a technologically advanced institution as an airport, it has been met with public scorn due to the colossal amount of electricity that is being wasted.
Brought down to a smaller scale, the principle still remains that lights left on mean not only unnecessarily high energy bills but also an excessive amount of carbon emissions - something which everyone should be taking responsibility to avoid.
Outdoor lighting can be the most common culprit when it comes to unnecessary electricity usage as people flick it on during the hours of darkness in order to feel safe, despite remaining inside the house, or perhaps in anticipation of returning home much later in an evening.
If this is a behaviour with which you are familiar, it may be time to consider a retrofit lighting project for the outside of your property, comprising lights which will switch on and off automatically using the help of motion sensors. Accordingly, there will be light when it is needed - but not at other times.
