Siemens proves that by implementing two primary technologies for building management and district cooling, energy requirements for cooling can be reduced by up to 40%.

According to Koen Bogers, senior executive vice-president, Building Technologies Division, at Siemens Middle East, cooling is responsible for approximately 70% of the GCC’s electricity demand during peak summer months.

He said: “So it’s extremely important that we evaluate the entire cooling chain to identify where technology can generate savings.”

Bogers outlined how digital technologies have the potential of making cities more sustainable and added that Siemens, by applying two technologies to the supply and demand sides, has made it possible to almost halve the energy used for cooling.

Siemens' Demand Flow technology uses specialised algorithms to enhance a cooling plant’s entire chilled water system, delivering energy savings of between 15 and 30%.

The system is able to reduce flow in lesser demand periods by simplifying operations, increasing the cooling capacity and improving efficiency. This lowers the operation and maintenance costs while significantly lowering energy use.

The system is already in place at the Wafi Mall in Dubai.

The second technology is a building management platform, Desigo CC which, by controlling and optimising a building’s systems, reduces energy usage. This included reducing ventilation, air-conditioning, lighting, shading, fire safety and security services. The system can make a saving of between 10 and 25% of the energy required for cooling a typical building.

Building with earlier versions of the Desigo building management system include Sheikh Zayed Grand Mosque in Abu Dhabi, Qatar’s Tornado Tower, the Atlantis Hotel in Dubai and Siemens’ own regional headquarters in Abu Dhabi’s Masdar City.

Bogers said: “Cooling amounts to some 70% of an average building’s electricity bill in the GCC, and aside from the clear environmental benefits there is also a very strong business case for these types of technology.”

He added: “For example, at Dubai’s Wafi Mall our Demand Flow solution achieved a 30% saving on utility costs in its first year, representing an annual cost saving of some $439,000 (QAR1.61m) with a guaranteed payback period of two-and-a-half years.”
