Client Profile
Wasl Properties is one of the leading and largest property management firms in Dubai. It was established by Wasl in October 2008 to manage an extensive real estate portfolio of over 40,000 residential and commercial properties within the Emirate of Dubai.
Project Profile
- Project Name: 4 Multi-use super high rise buildings comprises of (2 x 3B + G + 5P + 28F and 2 x G + 5P + 21F) including Retail, F&B outlets, Gym, Multi-purpose Halls, Play Areas, Sky Villas, and Penthouses.
- Location: Al Kifaf, Sheikh Zayed Road, Dubai
- Project Duration: 2017-2020.
- Project Brief: High-end residential and commercial complex having a total built-up area more than 2 million sq. ft. in a prime location.
The Al Kifaf residency is situated on the Sheikh Zayed Road in the heart of Dubai overlooking the famous attractions of Dubai like Dubai frame, Zabeel park and Zabeel palace.
Project consists of 12 high end retails including F&B’s at ground floor and upper floors consist of 786 modern state-of-the-art luxurious residential apartments, which includes sky villas and penthouses.
Energy Optimization, Space Optimization and Building Aesthetics
- MEP services risers and space allocation for services considering super high rise building above 100m height.
- Location of cooling towers to avoid visibility from lower towers in center from aesthetic point of view as well as mitigation of any possible spread of legionella from public health point of view.
- Due to complexity of project, multi-party coordination in limited time, i.e. IT, Security, Green building, fire life safety, vertical transport, ID, Lighting, Façade, Landscape etc.
- Lack of infrastructure design, resulting in changes in infrastructure tie-in points and challenges for coordination with local authorities
Design Approach & Solutions
- Integrated design approach
- Life cycle cost analysis between various design strategies to optimize the initial as well as operational cost.
- Precise MEP space planning, mechanical plant room coordination and shaft coordination carried out during schematic design stage.
- Selection of materials is with a sustainable approach with Zero Ozone Depletion Potential (ODP) & minimal Global Warming Potential (GWP).
- Application of horizontal louvers/shades, orientation of glass façade has been evaluated for reduction of air conditioning loads.
- All adhesives specified are with toxicity levels in-line with Green Building guidelines.
- The underground car-park lighting has been provided with timers and sensors.
- Ventilation with energy recovery for maximum indoor air quality and energy optimization.
- Detailed analysis to establish diversity factor of 0.65 for electrical load.
- Maximum Usage of daylight as well as maximizing external views.
Designing for Energy-efficiency
- High voltage centrifugal water cooled chiller selection with COP 7.0.
- All pumping and fans operating on VFD and VSD
- Cooling tower makeup water using grey water treatment plant.
- Integrated Building Automation & Chilled Water Plant Optimization.
- Demand control ventilation for highly occupied spaces like Gym, Multipurpose halls, etc.
- Advanced Energy Monitoring for Lighting, Power and HVAC System.
- Building envelope with 20% lower heat transfer coefficient as compared to authority requirements.
- Electric Vehicle Chargers for 5% of Total Parking Spaces.
- Advanced Power Factor Correction and Harmonics Mitigation Measures.
- Maximum lighting power density (LPD) of 3.8 W/M2.
- Fresh air handling units with heat recovery.
- Demand control ventilation for densely populated areas.
- Energy modeling and simulation during design stage to establish:
Efficient wall construction assembly
Efficient Roof Construction assembly
High Performance Glazing
Reduced Interior Lighting power Density
Water Cooled Centrifugal Chiller
FAHU with Heat Recovery Wheel
- The proposed building is able to achieve 23.88% energy savings when compared to base case in accordance with DM Green Building Regulations.
The Difference We Made
Successful implementation of design and selection of equipment in line with baseline as well as client project requirements.
