Client Profile
One of the pioneers in the education field; Amity established its university in Academic City, Dubai. It is one of the largest educational institutes in the Middle East region designed to cater 6,000 students.
Project Profile
The project comprises main university block, service blocks, hostel block, recreational facilities, sports facilities (indoor & outdoor), etc. The total built-up area of the project is approximately 75,800 sq. ft. The University was designed to create an environment that enthuses studying, inspires excellence and encourages physical and mental health and happiness. The campus includes top-of-the-range facilities and several wellness centres.
The design of the project started in January 2016, while the ambitious project was supposed to be operational in September 2018.
In order to meet the challenging timelines, the project was constructed in phases, however; the complete design of the project along with infrastructure coordination was handled to mitigate any construction related challenges.
Design Approach
To meet the challenging timelines, it was agreed to proceed further with University block, while; infrastructure details were not available. The designs were developed considering contingency as well as flexibility in the MEP design. Provision of STP, mobile generator interface, extra water storage capacity was planned.
The corridors for services were carefully planned to avoid any interfacing of services with future construction. Hostel block services provisions were planned along with infrastructure which reduced the construction costs.
Energy Efficiency in Design
The air-conditioning for the project was catered by a district cooling facility. The total cooling load was optimized to 8500 kW (110 W/m2) by using multiple techniques.
- The heat transfer coefficient for walls, windows and roof is selected for 10% reduced values as compared to authority regulations.
- Requirement of fresh air was reduced considering occupational diversity and time averaging method (ASHRAE 62.1)
- Considering non-simultaneous peaks of hostel block and university campus, the diversities on cooling load were enhanced to 0.7.
- All public areas were provided with fresh air based on Demand Control Ventilation (DCV).
- All fresh air handling units (FAHU), AHUs, pumps, fans were provided with VFD.
- Control systems were provided to increase the temperature to 27oC in no occupancy area.
- Fresh air handling units (FAHU) were provided with dual heat recovery wheels along with heat pipe resulting in heat recovery to almost 75%.
- All lighting was with LED having LPD 20% lower than ASHRAE 90.1 - 2013.
- All external lighting was controlled using photo sensors and timers.
- All indoor lighting was controlled using timers and occupancy sensors.
Other Design Measures
- Library premises were designed with humidity control to maintain humidity less than 50%.
- Condensate drain from all FAHUs was diverted to irrigation tanks and used for landscape purposes.
- Savings of 18% energy and 10% of water achieved with respect to baseline.
- Treated water was utilized for irrigation and landscape purposes.
- The swimming pool was provided with a canopy and shed to avoid losses due to evaporation as well as to impart comfort conditions for the pool users.
The concept of night cooling was considered in design where the fresh air having lower temperature at night was supplied through FAHU to take advantage of ambient conditions and save energy.
Rain water harvesting for the complete campus was planned with multiple soak pits, perforated crates and perforated piping to increase water retention within campus.
Hot water calorifier was considered with gas operation having efficiencies better than stipulated in ASHRAE 90.1-2013.
The Difference We Made
Successful implementation of design and selection of equipment in line with baseline as well as client project requirements.
Overall energy performance was established as 18% reduction in energy and 10% in water with respect to baseline of ASHRAE 90.1-2013.
