Discover the first KNX LED lamps, by Arcus! There are two models:
KNX-LED2: warm white / cold white
LED wall light with clear and smooth illumination up to 700 lm.
Main features:
• KNX-LED2 is a warm white / cold white LED lamp controlled via KNX- Bus and powered by KNX-auxiliary voltage.
• Change the color temperature to create individual moods and/or fit in the course of natural day-light. A spherical and a hemispheri¬cal shaped variant provides a wide beaming, diffuse and smooth backlight for walls and ceilings.
• A flat and compact design allows a space saving integration.
• Parameters and configurations can be optimized and adjusted subsequently via KNX bus.
KNX-LED4: RGBW
Flat wall light with light in a wide range of colors, illuminated sign.
• KNX LED4 is an RGBW LED lamp controlled via KNX- Bus and powered by KNX-auxiliary voltage.
• Choose and arrange the color via the KNX bus and set for warnings, information and/or presentation. This opens up the possibilities of a professional access control to conference rooms, switch rooms, treatment rooms or hotel rooms.

KIF Conclusions and Energy Efficiency star projects
We had the highest expectations regarding the KNX International Forum which took place last April in Madrid (Futurasmus KNX Group actively participated with our own booth). But, what should have been an international referent for the KNX standard market worldwide was unfortunately a mere regional congregation of Spanish KNX integrators. The lack of international visitors and exhibitors was a bit disappointing and some organizational deficiencies made the rest.
Anyway, there were also interesting conferences, like the applauded intervention from manufacturer Intesis, who talked about HVAC and saving methods.
But what we found especially interesting was the contribution of two private companies who shared their experiences in the field of Energy Efficiency and which we have extracted here:
Project: Hotel Condes de Barcelona
David Blanco Pérez from the company IJT S.L. presented at the KIF a very interesting project. They integrated the different systems (illumination, technical alarms, hot water supply, HVAC, pumps, tanks…) of the hotel Condes de Barcelona situated in the Paseo de Gracia in Barcelona. IJT achieved the main objective of the KNX integration which was to reduce the energy costs of the Hotel, even though the Hotel was expanded with another 56 suites, by up to 28% (corroborated by real invoices over the years 2007, 2008 and 2009). The energy savings was mainly achieved by the efficient control of the HVAC system by applying different modes and set-point temperatures depending on the usage of the rooms and outside temperatures.
Project: Heathrow T5
Maria La Chica from the English company ATL (Andromeda Telematics Limited) presented at the KIF the impressive 2006 KNX Award Project of the new Airport terminal, Heathrow T5. This is the Largest KNX Project and also the largest DALI lighting Project ever realized in the UK. The whole extension of the project included 2 major terminal buildings, the new flight control tower, major rail & road infrastructure, the energy centre, car parks, 120.000m sq of taxiway designed for A380 Super Jumbo.
The KNX Infrastructure includes 236 IP worlds, 910 KNX lines, 7.000 KNX devices, 64.000 DALI luminaries, lighting control, daylight dimming control, emergency lighting testing & monitoring, lamp failures, lamp hours energy calculation, control & monitoring of central batteries, LV monitoring, main plant monitoring, disabled WC alarms, lift & escalator monitoring / alarms, etc.
The most remarkable part of the presentation was the Final Conclusions: With a total CO2 emissions saving of 6,821 tons per year, a total cost saving of £1,362,498 saving per year, which leads to a final payback period of only 2.8 years for the whole project.
Please, contact us if you would like to receive more information about these remarkable projects.
As for the KNX International Forum, we wish them the best of lucks for the following editions.

The evidence we have been waiting for: KNX does save energy and now we proof it
Studies revealed by the KNX Association show how networked home and building control based on KNX allows up to 50% energy savings.
These are the achieved conclusions:
1) Institute for Building and Energy Systems at Biberach University of Applied Sciences: “Particularly automation functions, which present a high degree of energy-saving potential by combining various individual trades, can today only be achieved using modern building system technology based on bus and communication systems.”
2) Bremen Univesity of Applied Sciences: based on a four-year series of measurements, the use of KNX control was found to reduce energy consumption by an impressive 50%. It is thus clear that the expenditure in building automation system has quick payback.
The research project conducted at this University shows Energy saving with KNX on the extent to which energy savings based on the example of heating energy. The newly constructed Centre for Informatics and media Technologies (ZIMT) has been fitted with KNX controls and equipment for regulating heating and lighting. The data collected has been evaluated, and comparisons made between “normal” operation and “automation” mode. The building has a specific energy consumption of 60-75 kWh/m2a. Two identical classrooms were selected as test rooms. One was fitted with a conventional installation, and the second with KNX control.
The above mentioned University calculated that, with an annual energy consumption of 230,000 kWh for lighting alone, the investment would pay itself back after just one year with a KNX bus control. Ultimately it is not just the owners/operators and investors who benefit from the reduced energy consumption: the climate does as well.
In summary, KNX allows the following energy savings to be made:
up to 40% with KNX shutter control
up to 50% with KNX single room control
up to 60% with KNX lighting control
up to 60% with KNX ventilation control
