The Project

Cost savings – A builders merchant approached Capricorn to enhance the lighting in all of their depots by switching to energy-efficient LED lighting, not only to reduce their carbon footprint but also to cut down on their energy expenses.

Based on initial assessments, the client was told that they could expect to save roughly £1100 per month as a result of the lighting changes, with an estimated payback period for the client’s investment of approximately 8 months. The poor efficiency of the existing lighting system, made the switch to more energy-efficient options a smart financial decision.

However, the documented savings since installation are £2,000 per month – reducing pre-installation costs from £5,000 pcm to £3,000 pcm post installation and the ROI expectation has been reduced to just 6 months.

How does this Project demonstrate the diversity/flexibility of KNX?

Capricorn chose the SA/S8.16.6.2 Switch Actuator, 8-fold, 16 A, C-Load, Energy Function, MDRC. This was the optimal solution for our LED lighting system, as it efficiently managed inrush current while being compatible with the existing cable infrastructure. Additionally, we installed the TA 8 S KNX to facilitate binary inputs for light switches, and the Power Supply 160 mA MDRC – SV/S to ensure a reliable power source.

How does KNX add value and ease of use for building owners/occupiers

One of the main challenges they faced was the placement of the light switches, which had to be situated 30 meters away from the main panel. Additionally, the client expressed a desire for the potential addition of switches in new locations. To meet these requirements, Capricorn opted to use KNX devices instead of traditional wiring. KNX offered greater versatility in accommodating the client’s needs and future plans while still providing reliable and efficient lighting control.

How has this project resolved an identified need for the building user ?

Savings in electricity consumption due to the installation of LED lighting and KNX technology. Additionally, the carbon footprint of the building has been reduced, which aligns with the client’s sustainability goals.

Building users now have a more energy-efficient and sustainable lighting system, which also provides a comfortable and convenient user experience with the ability to control the lighting from multiple locations. Overall, the project has been successful in meeting the client’s requirements and delivering a positive impact on the environment and building users.
