The Gate Development, located at west bay; Doha – Qatar, is owned and managed by Salam Bounian, one of Salam International Group companies. The Gate (150,000 m²) developed and built as Core and Shell building which offers retail shops and offices for leasing, and includes the following:
1- Gate Mall; with approximate total area of 44,000 m², and four floors (GF to 3rd floor) is offering a luxurious shopping experience with the world leading brands. The mall working hours are from 9:00 AM to 12:00 AM
2- Three Towers; with total area of 57,000 m², each of 13 floors (4th to 16th floors) are leased to a well-known companies in Qatar including Qatar Petroleum. Companies start working at 8:00 AM to 6:00 PM.
3- Three basement levels of about 49,000 m² total area as parking and electromechanical infrastructure and services rooms.
Common areas (about 86,000 m²) represents about 57% of the total area in the Gate Development, and include three basements, common areas in the mall, stair cases and elevators lobbies in the three towers.
This project (ASHRAE Level II Energy Audit) was conducted to cover electrical systems in common areas and the total cooling services system serving the Gate. Following are the systems covered in this audit:
1- Electrical Power System
2- Lighting system in common areas
3- HVAC system including Chilled Water Pumps, Air Handling Units, Fresh Air Handling Units, Fan Coil Units in common areas and Split Air Conditioning System.
4- Building Management System (BMS)
Other systems such as lift system and domestic water pumping are considered as others, since they share about 2% to 3% of the annual electrical consumption.
Some actions and measures observed, that were taken during building development, and have contributed in energy efficiency, as all Fans in parking found controlled by VFDs (Variable Frequency Drives) and double speed controls, also chilled water pumps found controlled by VFDs.
All electrometrical equipment are monitored and controlled by BMS (Building Management System) which will help to implement some of EMOs easily.
