How to make historical buildings more energy-efficient

Heritage buildings around the world are typically protected from alterations which would negatively impact their architectural or historic interest. This makes wireless lighting control the perfect way to modernize a property and still preserve its cultural significance for future generations.

Due to their age, historical buildings are certainly not built to meet modern standards for energy consumption. And renovating them to become more energy-efficient without affecting the structural integrity of the property is incredibly challenging.

Lighting control is a common method of reducing a building’s electricity usage but traditionally involves installing new cables to connect all the light fittings to the control box. Since the construction work required to do this entails opening up walls, it is simply not possible to complete such a project if cabling is the only answer.

Thankfully there is one non-invasive solution which combines energy savings and the conservation of culturally important buildings – wireless lighting control.

Renovate heritage buildings without running cables

DALI is the standard protocol which all the different parts of a lighting system use to communicate with one another.

Traditional DALI lighting systems require all of the components to be connected together using DALI data cables for this communication to work, but wireless mesh technology removes the need for all this cabling.

The benefits of wireless mesh for historical buildings

  • Non-invasive installation to conserve interior architecture
  • Modernization of lighting system for greater comfort and better visitor experience
  • Improved energy performance in support of sustainability efforts
  • Enables energy savings through reduction of energy consumption

Quick and simple installation

By installing a DIN RAIL transmitter unit in the electricity cabinet next to the existing DALI control unit and placing receiver nodes for up to ten fixtures at once, a wireless network for lighting control is instantly created. For electricians, the DALI programming is the same, but the difference is: no new cables.

This means the existing lighting systems of old, protected buildings can be modernized without having to install additional cables and without damaging the architecture.

As a result, the building gets a smarter lighting network which allows, for example, the light intensity in a specific room or area to be adjusted and optimized according to the property’s needs for a certain time of the day.

It’s DALI, just without the cable

Wireless is the ideal alternative to installing DALI cables for retrofit or modernization projects.
