Building safety – protecting people and assets
Making a building safe is a complicated task. Increasing safety demands and certain laws and regulations must be observed. Add to this insurance company requirements and the complexity of the technical possibilities. A prudent safety concept ensures that as little as possible ‘happens’.
What are the risks of building operation?

Every building is different. Just like the people who use it. And the goods that are manufactured or stored there. The risks and hazards thus also differ. Anyone who is responsible for the safety of a building need to consider all the risks and protection goals in an analysis. A safety concept for the building takes legal provisions and insurance requirements into consideration.
The security measures for special buildings such as public buildings, kindergartens, industrial buildings, office complexes, high-rise buildings, hotels, shopping centres, schools, as well as hospitals and nursing homes are different from those for private buildings. It also always depends on how many people are in the building, whether they have restricted mobility and whether they are familiar with the building.

Safety concepts for buildings – what does it mean?
A safety concept includes all preventive or damage-reducing measures tailored to the needs, demands and protection goals. These are mainly fire protection measures, emergency exit protection, smoke extraction systems, access control and burglary protection. The safety concept for the use of the building must be aligned with the organisation’s overall safety concept and updated regularly - especially when changes occur in the use of buildings, for example following organisational changes.
If buildings have automatic doors and windows, the operator is responsible for their traffic safety. According to the European standard EN 16005 on safety in use for automatic doors, measures are needed to protect hazardous areas by:
- using sensors to avoid crushing, shearing and impact during opening and closing (sensors for presence detection)
- maintaining safe distances to prevent crushing and being drawn in
- limiting the leaf forces
According to German Federal State building regulations, structural systems must be planned, erected and maintained to provide sufficiently fire protection. Structural fire protection primarily involves the use of components and building materials, as well as the planning and construction of adequate escape and rescue routes for people and animals.
People use escape routes in the event of danger – for example in there is a fire or a situation of panic – to leave a building safely and quickly. These routes must already be defined during the planning of a building. A smaller building with less through traffic has different demands than, for example, a large shopping centre with a lot of through traffic. Masses of people need more space and flee differently than just a few people.
All doors along escape and rescue routes must be designed as escape doors or emergency exits. They must be marked accordingly and fitted with escape door locks in accordance with European standards. They must be fully usable at all times. Escape routes must be clearly and visibly marked and signposted for orientation.
The building regulations and special building specifications regulate whether and where fire protection closers (fire protection doors) are necessary in buildings. Their key task is to secure openings in fire-retardant or fire-resistant walls against the ingress of fire. They must therefore always be closed, or at least be closed in a controlled manner in the event of fire.
If fire protection doors are also to serve as escape routes, they must be able to be opened at any time. To simultaneously fulfil their function as fire protection closers, they need special locks that automatically close the doors after opening and also keep them closed – even without electricity - to prevent them from failing to open and thus making escape impossible. Or all of them opening and allowing access to burglars.
Escape and rescue routes must be as smoke-free as possible in the event of a fire so that people can move to safety and the fire-fighters can tackle the blaze. In the event of a fire, smoke and heat extraction systems (RWA) remove heat, smoke and toxic combustion gases from the building and keep them away from escape routes. Mechanical smoke extraction systems discharge the flue gases via fans. Natural smoke extraction systems use the thermal buoyancy principle to transport smoke directly to the outside via openings or windows.
Building safety also means protecting buildings, rooms, data and property against unauthorised access. It means granting only authorised persons access to certain areas in buildings or protected areas, usually sensitive areas such as computer centres, clean rooms, company areas, airports, banks, etc. The operator determines who is allowed to go where and when – even at specific times.
In an emergency, everyone must also be able to get out – but not everyone must be able to enter. This is where emergency exit protection systems come in: they manage the balancing act between controlled access and emergency opening with alarm (via emergency button) in the event of an emergency.
Although access control already keeps many unauthorised persons out, building safety is also about mechanical burglar resistance. Doors and windows must provide adequate protection against burglary, for example. Depending on the goal in protecting a particular area, decisions can be made in terms of the appropriate design of doors and windows.
According to DIN standard EN 1627:2011-09 "Doors, windows, curtain walls, lattice elements and closures - Burglar resistance - Requirements and classification", the components are classified in resistance classes (RC). Doors according to the RC1 to RC4 classifications offer higher protection against burglary due to their stability.
A safety concept is completed by detecting and monitoring measures. These ensure that both damaging events and accidental or intentional attempts to overcome protective and safety measures are detected as early as possible. For example, smoke detectors can detect fires at an early stage and trigger corresponding alarms. Burglar alarm systems, for example, show break-in attempts, while door guards at emergency exits draw attention to unauthorised use by means of an alarm signal.
Doors as the most important aspect when it comes to building safety

Doors can serve as building access, emergency exits and protected connections to other rooms with different functional areas. They have an important job to do in terms of building safety. They also meet other technical demands in terms of fire protection, sound insulation and accessibility.
As a result, automatic doors in particular have developed into complex systems with intelligent drives. Multifunctional doors fulfil the following functions:
- access control
- fire and smoke alarm
- escape door control system
- Protection by sensors, e.g. presence and movement detectors
If the door systems are integrated into building automation or building management systems, their operating status can be displayed and controlled remotely.

GEZE SecuLogic emergency exit systems
The GEZE SecuLogic emergency exit system is a complete and reliable system solution, especially for public buildings such as hospitals, schools or discotheques. In the event of fire or panic, it provides personal and fire protection as well as building safety. Various GEZE system components work together here: e.g. automatic door drives, door closers, motor locks and escape door electric strikes as well as fire or danger alarm systems and access control systems. The TZ 320 door control unit serves as the ‘brain’. The SecuLogic emergency exit system complies with the EltVTR (Directive on electrical locking systems for doors in rescue routes).
Self-locking panic locks provide uncompromising safety for both people and property in the event of an emergency. On the one hand, people must be able to leave a building in a matter of seconds to flee danger. On the other hand, owners and operators need to protect sensitive areas from unauthorised access.
GEZE offers self-locking panic locks (IQ locks) for this purpose. They ensure insurance-compliant locking, protection against burglary and controlled access, but also quick opening in an emergency.
GEZE SecuLogic access control systems
As compact, web-based ‘all-in-one’ system solutions with all the components relating to doors, the GEZE SecuLogic access control systems satisfy the demands of modern identification systems. Whether with a biometric fingerprint recognition or a card-based system – GEZE SecuLogic access control systems can be used for single doors as well as for networked door systems. GEZE SecuLogic access control systems are adapted step-by-step to the size and the demands of the safety concept.
The simple operation ensures the GEZE SecuLogic access control system is also suitable for private homes. Access control at the front door, bell signalling, sabotage monitoring or electric strikes make private buildings safer and protect privacy.
GEZE SecuLogic building technology management system
With the building system, system solutions for door, window and safety technology from GEZE can be integrated into building safety and control. A central control and visualisation system monitors various automation components in the building and offers security through many different networking possibilities: It ensures safe smoke and heat extraction (RWA), closes off fire sections, opens rescue routes or controls access.
It takes over the simultaneous monitoring of
- automatic door systems
- door closers on fire and smoke protection doors
- window drives for smoke and heat extraction (RWA) as well as for daily ventilation
- emergency exit systems and panic locks
- third-party products (e.g. light controls)
GEZE door systems with increased burglar resistance
GEZE safety doors make life difficult for burglars. They protect building entrances with more stringent safety demands (component resistance class 2). The transparent appearance of the systems is maintained regardless of the RC2 functionality.
