View of Phase 1 Development

Existing Green features of DIAC • District Cooling • Green landscaping • Non ‐ smoking buildings • Water conservation efforts • Recycling efforts • Laptops & Energy star labeled equipment • Energy management initiatives (BMS system) • Daylight access • Energy Efficient lighting • Shaded/ basement Parking • RTA (Roads & Transport Authority) bus lines • Adjacent retail & services • Use of local materials

Automatic timers and drip system used in Irrigation

Desert plants /Cactus and Local rock materials included in the Landscaping

Native “gaf” trees which require no irrigation / maintenance planted

Water Conservation Measures Water cost savings of 32 % achieved by Installation or Retrofitting of Ultra Low (0.5 GPM) Flow Restrictors on faucets

Water Conservation Measures Installation of bags inside the WC flush tanks Displacement = Savings 20 % savings per flush Savings of 6,000 Litres (1,600 gallons) day Less load on sewage network Total Savings of AED 92,000 per year (Including DEWA and sewage bills)

Water Conservation Measures Moisture retaining additives in soil Save 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 of environment

Water Conservation Plans for future • Construction of STP for DIAC ‐ under progress ‐ expected completion Q3 2009 • Use of treated water ( TSE) for Irrigation

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

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.

What is a Green Building

Why Design Atrributes ?

Why Buildings

LEED Certifications Pursuing LEED (Core and Shell) Certifications for DIAC Phase 3 Buildings Target Score Silver Final certifications expected by May 2009

Dubai International Academic City (DIAC) ‐ Phase 3 Green Building Certification LEED Score Card Under Evaluation by USGBC

LEED Certifications Energy cost saving of 21.7 % over ASHRAE 90.1-2004 has been achieved using • Energy efficient lighting • Optimized control on air handling units • Waste heat recovery • Reduced glazing area • Improved insulation over ASHRAE 90.1-2004 .

LEED Certifications Environmental • Refrigerants used in chillers is R134a which has zero Ozone Depleting Potential. • Recycling initiative at DIAC that is currently being studied. • No smoking buildings.

Certifications ISO 9001 : Quality Management System ISO 14001 : Environmental Management System OHSAS 18001 : Safety Management System LEED certifications : 1. Phase 3 buildings under evaluation – Silver Rating 2. Phase 1 & 2 buildings LEED EB in progress

Total Energy Savings Achieved in DIAC Jan.08 to Dec.08 Energy costs ( AED) AED 104,000 MWH of Energy 314 CO2 Emissions Tons 245 % Monthly savings ( Avg.) 7%

Energy Consumption Comparisons

Sustainable Business For most organizations energy management and conservation measures makes very good business sense
