WAFI Mall, Dubai
Opened in 1991, WAFI Mall is a gigantic, luxurious shopping, entertainment and leisure complex in Dubai. It includes an upscale shopping mall with over 350 stores and 30 restaurants, a 5-star luxury hotel and an underground market with magnificent Arabian architecture.Challenge
WAFI’s executive management wanted to make operations as efficient as possible and save energy costs. Since 2006 air-conditioning requirements of WAFI Mall have been provided by the 6075 TR District Cooling Chiller Plant 1, which is Middle East's first LEED Gold-rated HVAC plant. The goal was to optimize the performance of the HVAC system and the ability to monitor the performance of the chiller plant over the Internet.
Solution
Thanks to a long and positive partnership, MKM Commercial Holdings, the holding company for the WAFI Mall, decided in favor of the Demand Flow solution from Siemens for its energy optimization project. As a holistic approach for optimizing the entire chilled water system, Demand Flow’s specialized algorithms can deliver chilled water system efficiencies to any existing building automation system.
Implementation of Demand Flow was completed in July 2014. Guaranteed annual savings are $439,000. In addition, the performance of the entire chilled water system has been improved and its operation has been made easier. The web-based service platform Navigator from Siemens is used for system access. Navigator handles data acquisition, outputs energy profiles and displays detailed information about equipment operating parameters. The data is collected and aggregated by Desigo Insight.
Benefits
Lowering the overall energy consumption has allowed WAFI Mall to meet its medium-term goal of reducing primary energy costs and associated expenses. In addition, the project saves 1,800 million tons of CO2 emissions every year.
