1. Project Background

Al Manara Tower located in Business Bay, Dubai, is facing low chilled water Delta T issues. This has led to inefficient cooling performance and a notice from EMPOWER regarding potential penalties from 2023, 2024 & 2025.

The tower is equipped with:
- NETIX ODS BMS System
- FAHUs, AHUs, and FCUs serving common and retail/commercial areas
- Chilled water supply by Empower, with submetering via Aquacool

2. Consultancy Objective

To appoint a qualified MEP or Energy Efficiency Consultant to:
- Analyze the current Delta T issue
- Diagnose technical and operational inefficiencies
- Develop detailed engineering solutions
- Prepare tender documents for implementation
- Provide support through tendering, evaluation, and supervision

3. Scope of Consultant’s Services
