Beating the heat: cutting the GCC’s cooling cost by 40% with smart technology

Implementing two technologies for building management and district cooling could reduce by up to 40 percent the energy consumption for cooling during the GCC’s hot summer months. 

“Around 70 percent of the region’s power demand comes from cooling during peak summer months, so it’s extremely important that we evaluate the entire value chain to identify where we can use technology to generate efficiency gains,” said Koen Bogers, Senior Executive Vice President, Building Technologies Division, Siemens Middle East. “Digital technologies have huge potential to make our cities more sustainable, and we have proved it is possible to almost halve the energy used for cooling by applying two technologies to the supply and demand sides.” 

Siemens Demand Flow technology uses specialized algorithms to optimize the entire chilled water system of a cooling plant, delivering energy savings of between 15 and 30 percent. By simplifying operations, increasing the cooling capacity and improving efficiency, the system is able to reduce flow in periods of lesser demand, lowering operation and maintenance costs and significantly reducing energy use. The system is already in place at the iconic WAFI Mall in Dubai. 

The second technology, Desigo CC, is a building management platform which reduces energy usage by controlling and optimizing a building’s systems, including ventilation, air conditioning, lighting, shading, fire safety and security services. The impact on a typical building is a saving of between 10 and 25 percent of the energy required for cooling. Versions of the Desigo building management platform have been implemented in numerous buildings across the Middle East, including Sheikh Zayed Grand Mosque in Abu Dhabi, the Atlantis Hotel and the Office of the Future in Dubai, and Siemens’ own regional headquarters in Abu Dhabi’s Masdar City.
