The emeralds of the Emirates

We profile the only three LEED certified buildings in the Middle East.

We profile the only three LEED certified buildings in the Middle East.

Pacific Controls - platinum rated

Name of building:Pacific Controls

Headquarter - Techno Park

Architect:Kersey Modi, RIBA

Developer:Pacific Controls Systems LLC

Consultant:Orion Engineering Consultants

Contractor:Condor Building Contracting Co LLC

Condor Electro - Mech Contracting Co LLC

Interior designer:La Arch Plan PVT Ltd

Completed:November 2006

Specs of building:100,000 sq ft. The green rating process has been supervised and supported by CII (Confederation of Indian Industry). CII has been appointed as a consultant to ensure maximum possible green rating

When was it first certified:7 Jan 2006

What level rating does it have now:LEED- NC, LEED Version 2 Certification level-Platinum

In-house or outsourced FM team:In-house

What costs savings are being made:Energy saving 50% less than same non-green building

Waste use saving 90% less than non-green building

Water efficiency 40% less than non-green building

Pacific Controls is the first LEED platinum rated building in the Middle East. It is also listed as number 16 in the world.

It installed solar PV (photovoltaic) to use energy from the sun to create electricity to run appliances and lighting. PV requires only daylight - not direct sunlight - to generate electricity.

A 50kw solar photovoltaic system powers 16.3% of Pacific Control's energy requirement.

On the ground, solar panels capture the sun and provide constant, free of charge, energy. The panels heat water for the absorption chillers and it is used for both heating and cooling.

There are a total of 240 solar panels installed in the building.

Absorption chillers use heat instead of mechanical energy to provide cooling. These chillers can substantially reduce operating costs because they are powered by low-grade waste heat.

A non-polluting closed circuit cooling tower cools by dripping water over pipes containing the hot refrigerant. The cooling tower fans are each provided with variable frequency drive to economise on fan motor energy usage. Efficient chillers contribute significantly to the overall 66% energy saving in the building.

The sewage treatment facility eliminates the need for connection to and use of, the UAE public sewage treatment system. It reduces drinking water use and because it is used for irrigation purposes, it helps recharge the local groundwater system.

The building has a single high-speed IP-network backbone providing an open-standard protocol platform for the IT infrastructure.

The IP backbone integrates enterprise applications seamlessly onto a single information exchange to carry out enterprise-connected building management. For example, tenant billing, maintenance management, energy profiling and benchmarking of building equipment.

The building management system (BMS) enables the building to simplify FM and help the building become more cost-efficient, comfortable and safe.

Water saving devices such as waterless urinals, tap aerators, low flow toilets and water saving shower heads, reduce potable water use and reduce wastewater production.
Wafi Distrcit Cooling Plant - gold rated

Name of project:Wafi City District Cooling Chiller Plant DCCP ONE

Client:MKM Commercial Holding L.L.C.

Engineers and project managers:Green Technologies

LEED consultant:Green Technologies

When was it first certified:7 June 2006

What level rating does it have now:Gold, achieved on 29 November 2006

Wafi City achieved LEED Silver for its District Cooling Chiller Plant ONE (DCCP ONE) building on 7 June 2006.

Engineers and project managers for DCCP ONE, Green Technologies FZCO, who were also the LEED consultants, successfully achieved the gold rating in August 2006, making the project one of the first utility buildings to receive such recognition.

The LEED rating system attributes 25% of the credits to energy, 22% to indoor environmental quality and the remaining to water conservation, sustainable site and application of renewable materials.

As far as Energy and IEQ are concerned, the LEED standard is based on ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers) 90.1 and 62 respectively. The DCCP ONE's energy rating surpasses the ASHRAE 90.1 standard energy benchmark by more than 30%.

The project also used low VOC (volatile organic compounds) materials, waterless urinals, reduction of light pollution, high efficiency cooling towers, alternative transportation system and waste management to name a few, among many critical steps to achieve the Gold Award.
Metito Head Quarters - gold rated

Name of building:Metito Head Quarters

Architect:Vogue Etoile


Consultant:Serve U

Contractor:Sands Construction

Interior designer:Vogue Etoile

Completed/expected completion date:8 July 2007

What level rating did it achieve:Gold

In-house or outsourced FM team:In-house

Metito's new headquarters in Technopark is the third building in the Middle East to be LEED certified by the US Green Building Council (USGBC). The building incorporates several green features such as:

• Efficient use of water;

• Energy efficient & eco friendly equipments, renewable energy;

• Use of recycled and recyclable materials;

• Efficient use of landscapes;

• Effective control & building management systems;

• Indoor air quality for human safety and comfort.

Metito worked with a specialist LEED consultant, an accredited professional to guide and supervise the certification process and registration to USGBC to obtain the Green Building Certificate.

The objectives of the rating exercise are to lead in energy and environmental design, reduce operating costs (energy and water), facilitate good indoor environmental quality, create a sustainable design and improve life-cycle cost.
