Dubai Airports to save 20% on annual energy

bill with Siemens solution
· Siemens guarantees power and water savings for seven years
· Data analytics from automation systems used to design tailor-made energy
conservation measures

Dubai Airports will use Siemens’ data analytics and smart building technology to
guarantee annual energy savings of almost 20 percent per year at Dubai Airports’
facilities, by implementing energy efficiency measures at Terminal 1, Terminal 2,
Terminal 3 and Concourse B at Dubai International (DXB). Focusing on air and
water systems, the seven-year project is expected to reduce CO2 emissions by
approximately 25,000 tons, with annual electricity savings of approximately 50
gigawatt hours (GWH), and water savings of around 21 million gallons. The initiative
is part of Dubai Airports’ comprehensive energy-saving strategy and program
designed to limit the environmental footprint at both of its airports.

A tailor-made energy optimization solution has been designed for the project by
Siemens, comprising a range of physical and digital technologies including variable
frequency drives, panels, sensors, intelligent controls, energy metering and efficient
water fixtures. These will be deployed to the air and water systems to optimize the
air-handling units, chilled water system, fresh air plant and the secondary fresh air,
supply and exhaust fan systems.

“Sustainability underpins our facility management strategy and these energy and
water savings have the double benefit of limiting our environmental footprint and
improving our bottom line,” said Michael Ibbitson, Executive Vice President,
Infrastructure & Technology at Dubai Airports. “As longstanding partners, Siemens
understands our business, our systems and has the expertise and technology
needed to help us deliver our vision.”

“By optimizing technical infrastructure at Dubai International and providing enhanced

control and data analytics, we are able to guarantee significant resource savings
with sustainable environmental and financial benefits,” said Markus Strohmeier,
Senior Executive Vice President, Building Technologies, Siemens Middle East. “We
recognize that Dubai Airports operates mission-critical infrastructure, and we are
committed to using technology and expertise to ensure it is functioning at its most
efficient.”

Siemens will be responsible for the project’s design, supply, installation,

commissioning and maintenance, and also the measurement, verification and
guarantee of energy savings for seven years. The customer is Etihad ESCO
(Energy Service Company), a venture by Dubai Electricity and Water Authority
launched in 2013 to promote a performance contracting market for energy service
companies. Etihad ESCO aims to jumpstart the creation of viable performance
contracting market for energy service companies by executing building retrofits,
increasing penetration of district cooling, building capacity of local ESCOs for private
sector and facilitating access to project finance.

In October 2017, Etihad ESCO signed an agreement with Dubai Airports for the
retrofitting of Terminals 1, 2, 3 and Concourse B of Dubai International Airport.

Siemens is a pioneer in digitalized buildings in the Middle East, having implemented

smart building technology in key landmarks including Abu Dhabi’s Sheikh Zayed
Grand Mosque, Dubai’s Atlantis Hotel and 3D-printed Office of the Future, and the
recently-launched Dubai Opera.

 Siemens Delivers Infrastructure
Improvements and Energy Savings
for Crittenden Regional Hospital
Client Objectives
Serving the citizens of West Memphis, Arkansas Crittenden Regional Hospital (CRH) has provided
quality healthcare for over 50 years. As with all aging hospitals, it needed several infrastructure and
capital improvements to continue to provide an environment conducive to quality care and service
for its patients. Faced with rising energy costs and operational expenses, finding room in the capital
budget to make these improvements was a major obstacle and challenge.

Siemens Solutions
In October 2006 CRH issued a Letter of Intent to investigate the opportunity for reducing its utility
usage while improving occupancy comfort and staff productivity. In a proactive effort, CRH’s staff
selected Siemens Building Technologies (SBT) to perform an energy and infrastructure analysis of
their facilities. Over the course of several months, SBT interviewed staff, conducted site evaluations,
took measurements, and came up with creative and innovative ideas to reduce energy costs,
increase productivity, and improve infrastructures, all while working within CRH’s current operating
budget. Through this process, the Siemens team was able to propose a performance contract that
allowed CRH to make several infrastructure upgrades and energy efficient retrofits designed to save
more than 1.8 million kilowatt hours per year. The capital improvements, totaling $2.57 million, will
be paid for through guaranteed energy and operational savings equivalent to $3.9 million over
15 years. The CRH project included a multitude of improvements including:
• Lighting Retrofits
• New Chiller and Chilled Water Piping
• New Chilled Water Pumps and Variable Frequency Drives
• New Cooling Tower
• New Heat Exchanger
• New Boiler
• New Energy Management Controls System

Lighting
Siemens replaced existing lighting with new 30 watt energy saving T8 lamps and high efficiency
electronic ballasts that utilize low ballast factors, both provided by leading lamp manufacturer
Osram Sylvania (a Siemens Company). The lighting retrofit is expected to save more than 656,000
kilowatt hours per year. Also, due to the long life of the new bulbs and ballasts, additional material
savings will be realized with the lighting retrofit.

Heating and Air Conditioning

In regards to patient and staff comfort, Siemens replaced the older inefficient 500-ton chiller located in
the main mechanical room with a 700-ton McQuay variable speed chiller. The new chiller is more
efficient than the older unit and provides the hospital with much needed back-up for its cooling system.
This measure will save over 120,000 kilowatt hours per year in energy. In addition to the chiller,

 water pumps and piping. Siemens installed a new high efficiency boiler coupled with a plate frame
heat exchanger. The plate frame heat exchanger provides “free cooling” in the winter months by
using the cooling tower to directly lower the temperature of water used for cooling the
building.

Energy Management Control System

In an effort to increase productivity and occupancy comfort, Siemens installed an APOGEE® energy
management controls system (EMCS) in the hospital. The addition of the APOGEE EMCS allows for
remote monitoring, control, scheduling and operation of the facilities mechanical equipment. The
new EMCS, complete with a graphical user interface, gives CRH staff greater control of the central
plant and all of its equipment, as well as control of air-handlers located throughout the hospital and
the adjacent professional office building. Not only will staff have a greater control of the building’s
environment, but will save money by controlling HVAC equipment to tighter standards.

Client Results
James Carter, Jr., Chief Executive Officer of CRH, was very satisfied with Siemens and it’s overall
performance, quick response time, and ability to resolve issues with positive results. He explains,
“I have been in this business for over 15 years now, and John Hemenway (Siemens Project Manager)
is wonderful to work with. His attention to detail and responsiveness was beyond my expectations.”
In conjunction with his staff, Mr. Carter was actively looking for ways to enhance the image of the
hospital, improve services, and reduce rising operating and energy costs. Carter explains, “We are
excited about the anticipated annual savings that the upgrades and new technology installations
will provide. We have already seen the morale of the staff improve and heard the positive feedback
from patients. This creative and innovative concept of performance contracting allowed CRH to
provide a more comfortable and healthier environment for all its occupants.” The total project
guarantees an annual energy and operational savings equivalent to $260,000 per year for 15 years.
