Smart Buildings – Networked buildings with a future
Modern buildings should be safe and comfortable to use and control and consume as little energy as possible. These demands can be met with automation and intelligent networking of the technical equipment. Building networking is the largest growth market in the construction industry.
Buildings become safer, more comfortable and more energy-efficient
What constitutes a ‘smart’ building? Simply putting in a lot of ‘smart’ electronics for technical operation isn’t really enough. A building becomes truly intelligent only when all components work together in a coordinated way – across all manufacturers, centrally and easily operated. In fact, this applies to all product groups: lighting, heating, air conditioning, shading, ventilation and safety technology as well as door and window technology.
Thanks to their automated, networked building technology, Smart Buildings adapt dynamically both to the environment and to user behaviour. This makes them safer, more comfortable and more energy-efficient.
Communication via networks
The technical systems interact via modern electronic network communication. The programme for companies with respect to technical building equipment and building automation provides customers with both proprietary (manufacturer's own) as well as open systems. Open systems (e.g. BACnet, KNX, LON, SMI, DALI) are supported by many manufacturers: their components are thus ‘interoperable’ and can communicate with each other in a system.
What is ’Smart Building’?
Smart Building describes the automation and central operation of the technical equipment of functional buildings such as office buildings, airports, shopping centres or production halls. Core topics are the safety of the building – e.g. by fire alarm technology or dynamic escape route planning – as well as the energetic optimisation of the building operation, which saves operating costs on a large scale.
The electrical industry supplies Smart Buildings with numerous innovative products and solutions that have already been tested and are common in new buildings. The field of energy efficiency in particular has already achieved great success: energy consumption in an office building can now be reduced by up to 30% through automation.

Doors and windows also play their part
Smart ventilation: GEZE window drives, integrated in a KNX building system
Doors and windows are now also multifunctional, intelligent and networked. Because they have to fulfil many different functions: ensure accessibility, provide natural ventilation and ward off burglars. In addition, in the event of fire or panic, they must open escape and rescue routes, at the same time permit controlled access, ensure smoke and heat extraction and protect against fire.
GEZE offers KNX and BACnet interface modules as well as a building automation system for the integration of GEZE products in networking solutions. It allows automated GEZE products from the fields of door, window and safety technology to be monitored precisely and operated reliably. This enables the complete ‘intelligence’ of the products to be integrated into the building network: for example, setting the opening width of a door or opening and closing a window depending on the outside temperature in conjunction with temperature sensors and heating systems.

GEZE IQ box KNX – The specialist for natural ventilation
The GEZE IQ box KNX interface module is particularly suitable for implementing flexible solutions for natural ventilation in smaller buildings. The IQ box KNX enables the direct integration of the window drives of the GEZE IQ windowdrive series into KNX building systems. This facilitates dialogue with other KNX-capable components, such as push buttons and sensors. The IQ box KNX is easy to install, can be flexibly adapted to building use and can be combined with the entire KNX product world.
In schools, for example, building automation with the GEZE IQ box KNX ensures better air quality and energy efficiency through controlled, automatic ventilation. In the event of air deterioration during lessons, the windows open automatically (and close again). Night-time back cooling in summer ensures that the classrooms are cool in the morning. A sensor measures the inside and outside temperature and opens the windows at night when the outside temperature is cooler and closes them again automatically when the temperature is reached.
GEZE IQ box KNX product features
- open windows to any desired position (in %)
- reliable status report from any automated window (window open/closed/% of opening or drive state such as, e.g. malfunctions)
- integrated ventilation functions turn the IQ box KNX into a small ventilation centre (time ventilation, gap ventilation, automatic closing and locking in the event of rain or wind alarm, with activated air conditioning)
- dialogue with other KNX-capable components such as push buttons and sensors
KNX was developed as the ‘European Installation Bus’, EIB for short, by the electrical installation industry in the early 1990s. It is an open, decentralised bus system for building control. All devices use the same transmission method and exchange data via a common bus line. KNX is assigned to the field and automation level and also provides basic functions at the management level. More than 400 manufacturers worldwide offer KNX products for functional and private construction. Interoperability is ensured by mandatory third-party testing. Anything is possible - from a small ventilation solution for one room to building solutions with up to 50,000 KNX devices.
GEZE BACnet interface module IO 420
With the GEZE IO 420 interface module, GEZE networks products from the areas of door systems, emergency exit protection, window technology and RWA (smoke and heat extraction) as well as safety technology in buildings. The smart module is suitable for fast, simple and standardised integration into networking solutions with BACnet. IO 420 enables the central visualisation and control of all automatic door systems via the building management system.
BACnet solutions for multifunctional door systems: During the day a barrier-free automatic door – during the night a secure emergency exit. The TZ 320 door control unit controls and monitors automatic products such as the Powerturn swing door drive and enables integration into the building management system via the IO 420 interface module, thus enabling the door system to be controlled centrally via BACnet. If necessary, a different mode of operation can be quickly set and the door can be monitored remotely – including the receipt of possible fault reports.
GEZE interface module IO 420 product features
The new GEZE IO 420 interface module allows GEZE products in the fields of automatic door systems, window technology and RWA (smoke and heat extraction) as well as safety technology to be integrated into buildings via the BACnet communication standard.

BACnet (Building Automation and Control Networks) is a high-order protocol for building automation. It is developed under the auspices of ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) to create a manufacturer-independent communication protocol for intelligent components and systems in building automation. The protocol has been documented in ISO 16484 Part 5 since 2003.
BACnet allows devices from various manufacturers to exchange information with each other without incurring license fees for special data transmission hardware. BACnet is mainly used for building automation in functional buildings. Since BACnet is mainly used at the management and automation level, this system does not need its own transmission technology, but is based on existing technologies. The Ethernet or MS/TP transmission medium is usually used here.
Ideal for shopping centres: smart networks with GEZE Cockpit
GEZE Cockpit building automation system
GEZE Cockpit closes the gap in building automation with the first building automation system for smart door, window and safety technology. It can be used as an independent building automation system (stand-alone solution) or integrated into a higher-ranking building management system. The data exchange between GEZE Cockpit and the drive technology or safety systems takes place via the IO 420 interface module. GEZE Cockpit enables comprehensive visualisation, control and monitoring and displays (VISU) and monitors (VISU+) all events and activities.
GEZE Cockpit is the first smart networked door, window, and safety system.
Whether PC, tablet or smartphone: the applications on GEZE Cockpit are browser-based and can be operated on any IP-capable terminal device. For example, all connected doors and windows are displayed here at their exact location.
In addition, the current operating mode and the functionality of the doors or windows can be displayed on a graphical user interface and changed at the touch of a button. So-called ‘scenarios’ enable the simultaneous operation of several products – also at the touch of a button or time-controlled. Individual monitoring functions are equally possible, such as e.g. the evaluation of access frequency and alarms with e-mail reporting.
Building managers can control doors and windows without a visual inspection, get information from any location about changes in mode, and alarm or malfunction reports from individual doors or windows, and respond immediately. For example, if the emergency push button on an emergency exit is activated in a retail store, if a door in a nursing home is opened during the night without authorisation, or a door in a public building is not locked after closing in the evening.
