Our technical team services diverted around 3 million AED worth of penaltiess and resulting in annual saving of that said amount
The building is recognized as one of the most iconic structures in the United Arab Emirates (UAE). It is an 80-story skyscraper located in the Dubai International Financial Centre (DIFC) and is a mixed-use building designed for offices, residential, and retail purposes. Given the condition and capacity of the tower at the time, there was an opportunity for significant improvements through the integration of advanced, contemporary technologies and upgrades to the current equipment and systems.
With the goal of reducing their overall energy consumption, the client contacted Ark Energy to implement an Energy Efficiency Retrofit Program, as well as Delta-T Rehabilitation. The objective of this program is to reduce the client’s energy consumption, lower their operational costs, eliminate Delta-T surcharges, and digitize their energy management through our platform, arkEMIS.
From the conducted investigations, several sources of problematic energy consumption were identified. Firstly, the building’s chilled water network required a few enhancements. These modifications would involve optimizing the control of pump speed, improving the fresh air exchange rate of the existing Fresh Air Handling Units, and replacing the existing direct expansion air conditioning system (DX Units) with more efficient units.
In addition, the tower’s Building Management System (BMS) was found to be out of tune and in need of certain enhancements. These enhancements would include modifications in monitoring and controlling energy-consuming equipment, as well as providing access to override commands for building personnel. Furthermore, the electrical meters in use were not synchronized with a comprehensive energy management system, as they did not meet the minimum threshold.
As previously stated, the overarching goal of the program is to reduce the client’s energy consumption, lower their overall operational costs, eliminate their Delta-T surcharges, and digitize their energy management through our platform, arkEMIS. The data collected and analyzed over the past 12 months revealed clear figures indicating the specific sources of energy consumption aggregation. As shown in the figures below, the majority of the energy cost in 2018 amounted to 15.1 million AED. Within these costs, the tower incurred annual Delta-T surcharges of 2.63 million AED:

As the client’s consultant, Ark Energy provided the following implementations to achieve the main objectives of this project and address the specific sources of energy consumption:
The results that were generated from the project include the following:
