Commercial building in Malta gets smart, secure and green

SmartCity Malta (SCM01), a commercial building covering 2.96 acres (12,000 square meters) of office space spreading over seven stories in Ricasoli Estate in Malta, integrated its security system, which comprises intruder detection, video surveillance, card readers, and controllers with building management system to achieve Leadership in Energy and Environmental Design (LEED) green building certification. SCM01, is the first LEED certified building in Malta. System integrator Engineering for Science and Industry (ESI) Malta was the system integrator that managed, designed and installed the system, which integrates Honeywell's security management system with Tridium building management system (BMS).

A key element in optimizing SCM01's efficiency was enabling the security management system to share signals with the BMS. As a result, SmartCity Malta required a mechanism that would integrate the two systems. A Honeywell corporate edition security management system was installed to control the access of 30 doors and ESI Malta integrated the system with the Tridium BMS by producing a specific adapter using the Honeywell software development kit. This adapter enables the security management system and the BMS to efficiently share each other's input and output signals.
 
MIFARE card readers are also installed to monitor when an access control card is presented at door entry and exit points. Using Honeywell intelligent controllers, the security management system sends signals to the BMS whenever an access control card is presented to one of the readers. The access control cards can be programmed with cardholder's credentials including their personalized preferences for temperature and lighting settings. Due to the integration with the BMS, these settings are then applied based upon the person's location within the building.
 
The BMS also receives inputs from other security and safety related systems which are now displayed and recorded via the security management system too. Such systems include; fire alarm (where the individual ‘fire zone' is identified), emergency lighting, uninterruptible power supply (UPS), back-up power generator, water leakage alarm, IT infrastructure and voice alarm system. For example, when an emergency event such as a fire alarm is triggered, the system automatically records and displays video images of the specific zone. Equally, in the event of a failure with the UPS, an alarm is shown via the security management system interface.

Video surveillance of the public areas is carried out with Honeywell IP PTZ mini domes and box cameras. The HD images are captured and managed by the VMS which also integrates with the security management system. Intruder detection is also integrated via the security management system. Sturdy and reliable motion sensors and door contacts are installed throughout the building. Alarm outputs triggered from these are managed by VMS and live video instantly shows the area in question on the video wall. Operators are quickly and clearly alerted to alarm events and incidents, and video pursuit is possible via motion detection using a set of surrounding cameras. At the same time, the BMS sounds a siren and increases the brightness of the lights in the area where the intruder is located.

Via the security management system, the BMS assesses the occupation levels of the building 24/7. At night time, to optimize security, additional footpath and car park lighting can be turned on when any cardholders working late leave the building. The security team manages and controls the system via a dynamic, graphical user interface- the ‘Alarm and Event Monitor', which displays clearly all alarm statuses and conditions from the BMS and Pro-Watch. For added convenience the interface is integrated with computer tablets and smart phones for access away from the control room.
 
Providing a state-of-the-art Information and Communications Technology (ICT) infrastructure with a converged BMS and security system within a technologically-advanced green building not only underpins SmartCity Malta's corporate responsibility towards the environment, but it allows it to differentiate itself from other commercial buildings and developments to help attract worldwide ICT brands as tenants.
