Smart lighting control is becoming the key to energy efficiency in buildings – Lichtwart shows how intelligent retrofit solutions save energy, make use of subsidies, and drive forward the building transition.

According to a recent article in Handelsblatt, lighting is increasingly becoming a focus of energy efficiency in buildings: in addition to the switch to LED, intelligent lighting control is playing a particularly important role. In the future, presence and daylight sensors as well as networked systems will ensure that light is only used when and where it is needed, thereby saving energy.

The planned EU Buildings Directive (EPBD) sets clear targets for the energy consumption of buildings and calls for comprehensive modernization of existing buildings. According to the article, around 85% of today's buildings will still be standing in 2050 – the pressure to renovate is enormous.

Why Lichtwart starts right here

  1. Efficient lighting control
    Our Lichtwart solution enables automatic adjustment of light intensity and operation depending on daylight, presence, and usage scenarios. The result: lower energy consumption with the same or better comfort.
  2. Sustainability & verifiability
    The Lichtwart system allows consumption and savings values to be transparently recorded and documented – an advantage in view of increasing requirements due to EU regulations and interested real estate investors.
  3. Flexible retrofitting in existing buildings
    While many buildings require costly renovation, Lichtwart offers a simple solution: existing lighting is intelligently supplemented instead of completely replaced. This means that modern technology can be quickly utilized without major disruption to day-to-day business.
  4. Strategic contribution to the building transition
    The Handelsblatt article describes light as “not static,” but as an active part of the energy transition. Lichtwart transforms this statement into tangible solutions – companies, operators, and owners can use it to reduce costs and improve their carbon footprint.

Lighting is thus evolving from a simple “ON vs. OFF” light switch to a digital energy management tool. The article highlights how relevant this topic has become and how we can actively shape change in existing buildings: efficiently, measurably, and easily retrofitted.

Act now – with Lichtwart and funding support

In combination with the introduction of an energy management system, there is the opportunity to receive government subsidies – a decisive advantage in reducing investment costs and implementing projects more quickly.
