Sustainability In Education Facilities Diac Bfe Mena 2011

  1. 1. Dubai International Academic City Ayoub Kazim
  2. 2. Overview• Dubai International Academic City (DIAC) is the world’s only Free Zone dedicated to Higher Education.• Launched in April 2007.• DIAC aims to develop the regions’ talent pool and transform Dubai to a Knowledge based economy.• DIAC has 27 Academic institutions and more than 20,000 students in 2010/11 Academic Year.• Spread across an 18 million sq. ft. campus.• Academic partners from 11 countries, including the U.S, Australia, India, Pakistan, Canada, Iran, France, Russia and the U.K.• Over 300 Higher education programmes including Diplomas, Undergraduate Degrees and Post Graduate Degrees.• First Silver LEED™ Academic Cluster in the Middle East certified by the US Green Building Council.
  3. 3. Our PartnersDIAC has partnered with some of the most prestigious Higher Education institutions fromaround the world including:• University of Wollongong• Middlesex University• Michigan State University• Hult International Business School• British University in Dubai• Manipal University• Heriot Watt University• Manchester Business School• Murdoch University• University of Bradford• University of Phoenix• SAE Institute• BITS-Pilani
  4. 4. What is a Green Building ?A green building has a design which focuses on:• Increasing efficiency of resource use – energy, water, & materials.• Reducing building impacts on human health and the environment during the buildings lifecycle. Source: USGBC
  5. 5. Why build green? Green buildings can reduce Perceived business benefits of green Energy Use by 24%* - 50%** 3.5% occupancy value increases 6.6% return on ratio increases Water Use 7.5% building 3% rent ratio by investment increases improves 40%** CO2 Emissions by 33%*** - 39%** decreases operating cost 8 – 9% Solid Waste by 70%** LEED Certified project case studies illustrate 2 – 16% increased worker and student productivity ***** Turner, C. & Frankel, M.

  7. 7. View of Phase 1 Development (Buildings 1 ,2, 3 &4)
  8. 8. View of Phase 2 Development (Buildings 5 ,6, 7 &8)
  9. 9. View of DIAC Phase 3 (Buildings 9 ,10, 11 &12)Awaiting LEED Certification
  10. 10. Existing Green and EHS Compliant features of DIAC• District Cooling• Landscaping and water features• Non-smoking buildings• Water conservation efforts• Recycling efforts• Usage of solar energy• Energy management initiatives (BMS system)• Energy Efficient lighting
  11. 11. Green Feature: Water Efficient LandscapingIntent: Limit or eliminate the use of potable water or other natural surface or subsurface water resources available on or near the projectsite, for landscape irrigation (Source: USGBC) Ghaf and Cactii as well as Drip and timer controlled Usage of soil additives to other adapted and low irrigation network reduce irrigation water water consuming plants requirements and NPK used in landscaping Fertilizer usage. 16 million • Reduction in landscape water gallons requirement per year
  12. 12. Automatic Timers and Drip System Used in Irrigation
  13. 13. Water Conservation Measures Moisture Retaining Additives in SoilSave 50 % irrigation water usage because, – Ties up a high amount of irrigation – Reduces the usage of NPK fertilizers drastically by prevention of leaching out – Improves the soil structure – Reduces the percolation rate of the irrigation water in the soil – No pollution to environment
  14. 14. Water Conservation Measures Water cost savings of 32 % achieved by Installation or Retrofitting ofUltra Low (0.5 GPM) Flow Restrictors on 800 faucets
  15. 15. Water Conservation Measures Installation of bags inside the 950 WC flush tanks Displacement = Savings 20 % savings per flush Savings of 6,000 Litres (1,600 gallons) day Less load on sewage networkTotal Savings of AED 92,000 per year (Including DEWA and sewage bills)
  16. 16. Water Conservation by on Site Sewage Treatment PlantsExisting sewage holdingtanks 6,800 m3 capacityare converted into STP’swith SBR technology.
  17. 17. Energy Conservation Measures District Cooling • District Cooling services Proposed Permanent using 0.9-1.0 kW/ton District Cooling Plant • DIAC phases 1 to 3 with a capacity of 5100 RT saves 2,550 KW
  18. 18. Energy Conservation Measures De-lamping in Offices RESULTS • 4 Lamps (4 x 18W) per fitting reduced to 2 lamps . • Saved kW without compromising on lighting quality. • Lighting Energy index reduced from 21 W/ m2 to 10 W/ m2. • 52% savings in lighting power. • Reduced heat load from lighting. • Reduced energy and C02 emissions. • Improved in comfort / indoor climate
  19. 19. Energy Conservation Measures • Use of LED Lights for pavement lighting. • Phasing out of Halogen lighting Results • Huge savings in lighting power. • Reduced energy and C02 emissions.
  20. 20. Potential of Major Renewable Energy in UAE• Wind Energy:- Production of Electricity.- Pumping Water.• Solar Energy:- PV Cells and Solar Collectors.• Biomass Energy:- Solid and liquid waste• Geothermal Energy
  21. 21. Solar Tracker - 2.9 kW of connected load to power 129 lamps. - 6 tons of CO2 saving per year.
  22. 22. Green Feature: Alternative Fuel VehiclesIntent: Reduce pollution and land development impacts from automobile use. (Source: USGBC)Dubai International Academic City (DIAC) is committed to reducing carbon emissions andas part of this DIAC would like to provide preferred parking next to the buildingentrances in the basement for DIAC community using low‐emitting, fuel‐efficient vehiclesand hybrid cars.Selection Criteria• All models of year 2000 ‐ 2009 vehicles that meet the U.S. Green Building Councils LEED criteria by scoring a rating > 40 and listed in the excel sheet provided and can be downloaded at http://www.greenercars.org/news.htm• The first phase of 10 car slots is open for faculty and staff only.• Preference will be given to community member currently not holding an access card.• Applicants are requested to provide relevant details of the cars to prove compliance with the LEED requirements along with the copy of the Car Registration documents to email: prm@diacedu.ae DIAC Phase 3 is one of the first educational organizations in the Region to implement this Credit.
  23. 23. Green Feature: Indoor Air Quality Strategies: • All 5 buildings at DIAC Phase 3 have a ‘NO SMOKING’ policy. In fact, smoking is also not allowed within 25 feet of building entrances. • These facilities enjoy 30% more fresh air compared to ANSI/ASHRAE 62.1- 2004: Ventilation for Acceptable Indoor Air Quality standard requirements, making the buildings very healthy for its occupants. • During construction, an air quality management plan was implemented which ensured dust and particulate matter due to construction did not continue to reside in the air-conditioning ducts. • The HVAC systems comply with ANSI/ ASHRAE 55-2004: Thermal Environmental Conditions for Human Occupancy standard, and thus provides a comfortable thermal environment for building occupants
  24. 24. Green Feature: Construction Pollution ManagementIntent: Reduce pollution from construction activities by controlling soil erosion,waterway sedimentation and airborne dust generation (source: USGBC) Dust Control: Construction activities such as land clearance, earth movement, off- road vehicular traffic etc. generate a lot dust which is harmful. This project employed various measures such as wetting of loose soil, in order to mitigate this impact. HVAC Protection: HVAC equipment such as Fresh Air Handling units & Fan Coil Units were kept sealed during construction and till before use. Source Control: Fans were used to ventilate enclosed spaces with no natural ventilation Pathway Interruption: During construction, site facilities such as offices, canteens & rest areas were segregated from site work area. Perimeter fences were set up to segregate the site from surroundings. Scheduling: Activities such as painting were scheduled at times that minimized exposure of sink materials such as furnishings & false ceilings.
  25. 25. Baseline vs Design Utility Cost Summary Utility Cost Comparison (All figures in AED/ year) 4,418,731 Total annual savings = 4,500,000 AED 2,376,763/- per year. 4,000,000 3,461,747 3,500,000 3,000,000 2,325,000 2,500,000 1,627,500 2,000,000 1,443,105 1,500,000 866,437 1,000,000 189,163 129,595 273,235 187,192 500,000 - Domestic Water Sewage Tanker Cost Irrigation Water Energy Cost District Cooling Cost (temp) Cost Demand Charge Conventional LEED Silver (if LEED was not pursued)
