The change in the Speicherstadt historical warehouse district, Hamburg’s only UNESCO World Heritage site, is obvious. The former beating heart of the Port of Hamburg – where goods from all over the world were once brought in by boats and barges and stored in the hatches of the largest warehouse complex at the time – has been developing into an attractive and diverse urban district ever since the area was separated from the free port in 2003.
The transformation is being driven forward by the Real Estate segment of Hamburger Hafen und Logistik AG. The warehouses thus shine in new splendour while preserving their original features as closely as possible and under the strict eyes of the landmark protection office. However, technology’s progress cannot be stopped by thick red-brick walls.
Christian Stange from HHLA Real Estate oversees the technical equipment of all HHLA properties in Hamburg. He ist member a ten-member team, responsible for maintenance, inspection and repair of hundreds of technical facilities. Legal requirements and modern standards regarding fire protection, building energetics, heating and air conditioning technology, security systems and much more also apply to World Heritage sites.
In the past year, the technicians in Stange’s team set a new project in motion in order to make their jobs easier and therefore more effective. At the same time, the service offered to HHLA’s tenants was improved further. The name “Digital building control system” (GLT in German) stands for the visual networking and remote-capable control of all technical facilities through a central software system.
Stange sums it up using a practical example: “If a heating unit stopped working today, the tenant would call and report the disruption. One of our technicians would then first assess the situation on-site. In some cases, we have to commission specialists who might realise that they do not have the adequate replacement part with them. And until the disruption has been resolved, the tenant will have no heating.”
GLT will considerably simplify this process. “The software will proactively notify us if something’s wrong with the heating system – preferably before the tenant starts feeling cold,” Stange explains, describing the future. “Ideally, the notification will also include information about the type of disruption and required spare parts.” A specialist company will then be commissioned automatically by the system.
Stange sees great potential in digital building control systems: “Even though GLT will initially have no influence on the number of disruptions, solving them will be much faster and more efficient.” Furthermore, the coordination of repair efforts will be easier. This can help to avoid double-booking specialist companies and to optimally bundle orders. And we cannot forget the economic advantage: fewer complaints would also mean less rent reductions because repair work will be accelerated.
According to Stange, the optimal monitoring of the efficiency and energy consumption of the technical facilities with the help of GLT would also be decisive. “This would allow us to reduce our energy consumption by ten to twenty percent,” the specialist estimates. That would be a good contribution to the HHLA Group’s goal of becoming climate-neutral.
We plan to connect the first Speicherstadt buildings via a central GLT system in 2021. Further HHLA properties at the port will also be integrated. The process will continue gradually after that. Achieving this will partially require establishing the network technology demanded by the technical facilities in older buildings. This has already been included in the plans for new renovation projects.
The member of the Executive Board responsible for the Real Estate segment, Dr. Roland Lappin, is enthusiastic about the project: “The establishment of a central digital building control system is a key requirement to position the Speicherstadt historical warehouse district at the forefront of sustainable buildings. The required expertise and skills to achieve this are firmly anchored in our real estate strategy.”
HHLA Real Estate has opened up the Speicherstadt for attractive inner-city use. To ensure that the quarter is transformed, HHLA developers are sensitively renovating the historic building fabric.
