Odour & Grease Neutralization System for Commercial Kitchen Exhaust
Ozone is one of the strongest commercially available oxidizing agents, and is commonly
used in the neutralisation of heavy cooking smells in commercial kitchens and removal of
grease in the kitchen exhaust air ducts. The system is manufactured in Sweden and is also
used as decontaminant and disinfection agent in hospitals and to kill smells and VOCs in a
variety of applications.

Company Profile
13
As shown in this Figure, ozone consists of three Oxygen
atoms. Under normal conditions the gas is unstable and
thus very reactive. The free Ozone molecule reacts quickly
with a number of organic and inorganic compounds and
anything with the potential to oxidize.
Ozone is used up completely by this oxidation process and
breaks back down into Oxygen (O2). Any remaining
Ozone in the off-gas is converted back to Oxygen. This
oxidizing ability is used to eliminate odours, bacteria and
viruses.
Ozone has a characteristic chlorine-like smell that is already noticeable at 0.01 ppm. While
Ozone is very powerful, it has a very short life cycle. When it is faced with cooking smells,
grease, bacteria or viruses the extra atom of Oxygen destroys them by oxidation.
Besides the overriding characteristics of acting as an unprecedented purification agent
when injected in air, ozone has several other advantages over other chemical alternatives.
For example:
1. Ozone oxidizes rapidly and decomposes equally fast to Oxygen leaving no traces.
2. Ozone reactions do not produce toxic compounds.
3. Ozone acts rapidly, and more completely than other common disinfecting agents.
4. Eliminates the use of high costs UV tubes.
5. Eliminates the use of heavy ecology units requiring large space and
Shown overleaf is a comparison between ozone systems versus ecology units and UV-
lamps for commercial kitchens.

Wet-wall Evaporative Cooling System
®
Our Wet-wall Evaporative Cooling System®
is the product of our vast experience and long
research into innovative energy conservation systems. Our Wet-wall Evaporative Cooling
System®
has been especially designed to improve the efficiency of air cooled chillers by
reducing considerably (up to 14 o
C) the ambient dry bulb temperature to the condenser coils
of air-cooled chillers.
Since air cooled chillers work more efficiently at lower air temperatures, the Wet-wall
Evaporative Cooling System
®
results to a considerable reduction in energy consumption of
air-cooled chillers and hence monetary savings.

LEED (USGBC) Certification for Existing Buildings
In addition to Green Building Certifications for new Buildings, we also undertake LEED
Certifications for existing buildings under LEED vers 4 O+M where the emphasis lies in the
Operation and Maintenance of existing buildings.
Using our combined knowledge on Sustainability and Energy Auditing and Energy
Conservation we deal with a number of issues relevant to an existing building such as:
 Location and transportation available to the occupants
 Sustainable sites
 Water efficiency
 Energy and atmosphere, including optimisation of energy consumption and
commissioning of electro-mechanical equipment at set intervals.
 Materials and resources used in the running of the building
 Indoor air quality.
In this aspect and among others, we have successfully executed a LEED-O+M certification
program for GASCO Administration Office in Ruwais, Abu Dhabi.

ISO 50001 Energy Management System (EnMS)
Apart from our Sustainability and Energy Conservation work, our services extend to the
implementation of ISO 50001 Energy Management System (EnMS) for large organisations.
Contrary to ad-hoc energy conservation programs, an Energy Management System (EnMS)
benefits from the inherent, continual improvement process of an EnMS that follows the Plan
- Do - Check - Act or PDCA approach. Figures 1 and 2 below show the operating cycles of a
typical energy conservation program versus an EnMS program.
Fig.1 A typical ad-hoc approach to energy efficiency
Fig.2 An EnMS systematic approach to energy efficiency
From the graphs above, ad-hoc energy conservation programs “oscillate” about some
average energy performance value with only marginal energy improvements over time. On
the contrary the EnMS approach allows for consistent energy improvements, year after year
due to the inherent, continual improvement action in the ISO 50001 energy standard.

Company Profile
23
Greenfield has been preparing the EnMS program for ADNOC in Abu Dhabi, including
various facilities such as Ruwais Housing Complex, ADNOC HQ, ATI Training Complex and
many more.
The EnMS process in such projects follows the Plan – Do – Check – Act approach (Plan-Do-
Check-Act, PDCA) which is shown below.

Energy Value Analysis
Value analyses for new projects
has the advantage of reducing
initial capital cost, improving
operating cost in the long term
and avoid flaws at design stage.
Our engineers have been
involved in Value Analysis
projects since the early 2002 with
the development of the Green
Community and later the Burj
Development in the UAE.
Using our envelope design
expertise and building modeling
tools, we review the cooling load
calculations and optimize the
size of chilling equipment
avoiding unnecessary
redundancy. We calculate the
energy consumption for any
building at design stage to help
the Client to set the correct
service charge and predict the
energy expenditure.
In case of infrastructure projects, we run parametric studies of the orientation, construction
materials, glass, external shading and more to optimize the cooling load for each typical
building. We then optimize the electrical and cooling loads in totality taking into account the
diversity factors for the various buildings, depending on their physical location, height and
nature.

Energy Modelling
Our team members have in excess of 25 years experience in thermal modeling, which dates
back to 1986 in the UK with the use of the Thermal Admittance Method, SERI-RES, HTB2
and ESP-r. Currently, much of our modeling work in relation to LEED-USGBC or Estidama
rating systems takes place using Design Builder, Visual-DOE and e-Quest.
We are presently handling several energy model projects under the Estidama Pearls rating
system for Abu Dhabi Urban Planning Council. They include, among others, the Danat Al
Emarat Hospital, Borouge Innovation Centre, Petroleum Institute, Al Maqta ADNOC
Residential Development, Al Forsan and many more.
Whether simple or multi-storey
buildings, our modeling work involves a
series of parametric analyses on the
effect of orientation, massing,
construction materials, glass and
shading on the cooling load. For each
run, the cost implications are also
assessed, thereby enabling us to
calculate the initial cost and long-term
energy budget in each case.

Greenfield routinely runs thermal
simulations of complex of buildings in totality
taking into account the diversity factors of
the various buildings. It is well known that
the location and height of buildings can
impact the degree of shading to each other
and buildings of different nature meet the
peak chilled water demand at different times
of the day. By exploring these differences
Greenfield can calculate the optimum chilled
water plant to reduce initial cost by applying
the proper diversity to minimize equipment
redundancy.

LEED & ESTIDAMA Commissioning Agents
In addition to LEED Certification, Greenfield also offers its services as LEED Commissioning
Agents which is a pre-requisite in LEED and ESTIDAMA Certification projects. Our
experience in commissioning of energy systems in building goes back in excess of 15 years
and covers equally well the areas of air-conditioning, ventilation, daylight and artificial
lighting and renewable energy systems. Working on behalf of the Client, we strive to ensure
that the design themes are correctly carried through the construction and the systems are
properly commissioned to produce the expected energy reduction and indoor air quality.
Given our experience as LEED
Assessors, we are acutely aware
of the intricacies of the
documentation that is needed in
LEED Certification projects in
relation to commissioning of
energy systems. Our work
begins with a review of the
Owner’s Project requirement and
Basis of Design documents. We
make sure that the
commissioning requirements are
reflected correctly in the
construction documents and
prepare the commissioning plan.
After the verification of
installation and performance of
the commissioned systems, we
complete the commissioning
report for USGBC. For
Enhanced Commissioning in
particular, we review the building
operation within 10 months after
substantial completion of the
building and advise on any
shortcomings.

CFD for Building Applications
Over the last 3 years, our Computational Fluids Dynamics (CFD) team has been very active
in the study of air flow movement in office buildings and also the design of intricate building
envelope designs using double skins glass structures to mitigate solar gains into the
occupied space.
Other times, our CFD experts
simulate car park ventilation
systems to ensure that the
mechanical ventilation system is
not liable to pockets of high CO
levels, which could put in danger
the life of car park users. Along
with such studies we also
investigate the dispersion of
smoke in the event of fires in
underground car parks and the
control regimes of ventilation
fans under such conditions.

Indoor Air Quality
Under Indoor Air Quality, Greenfield offers a complete solution involving both monitoring of
the quality of the indoor environment but also mitigating any identified problems. In
collaboration with CamFil International, Greenfield is equipped to undertake in-situ
measurement of many types of indoor air pollutants, be it gases, particles or others. At the
end of the measuring process, Greenfield can provide a series of solutions to suit different
environments. These solutions differ from stand-alone high efficiency HEPA filters for small
to intermediate size projects. For larger projects, such as hotels, hospitals or airports
Greenfield is collaborating with a Swedish Company whose IonAir patent technology
neutralizes smells and VOCs and kills germs. Its unique technology creates ion levels in the
occupied environment that mimic the air conditions after thunderstorms to rejuvenate the air,
and hence improve comfort and human energy levels.

Energy Auditing & Energy Conservation
Greenfield has over 30 years of experience in energy auditing and energy benchmarking of
energy consumption for commercial buildings, offices, shopping malls, government
institutions, hotels, residential buildings, different types of industries and more.
We are the pioneers of energy conservation in the UAE and continue to lead the way in
energy optimization projects to this date. We have carried out in excess of One Hundred
Energy Audits for existing buildings including some of the largest Hotel chains in the UAE,
residential towers and shopping malls.
Our energy conservation programmes achieve on average energy savings between 13 to
30% of the annual energy bill with payback periods between 1 and 2 years.
 Energy consumption data gathering and analysis: It is the first step in the energy
auditing and review process. In addition to the soft data collection from the engineering
department we also log and measure the data as shown below;
The data analysis leads to establishing an energy baseline consumption and
identification of major energy users.

 Financial Analysis& Projections :
For the informed decision making by the CFO, various key indicators such as; simple
payback; cash flow; NPV; IRR; life cycle analysis and cost of not doing the project are
worked out. Also the future consumption pattern is projected for easy comparison as
shown below;
 Economic Evaluation
Methods for Evaluating Energy Cost Reduction Projects:
 Simple Payback
 Internal Rate of Return (IRR)
 Return on Investment (ROI)
 Net Present Value (NPV)
 Life Cycle Cost Analysis
 Consider total cost of ownership, not just upfront cost (operating cost usually
significantly outweigh first cost.
 Pay more now, save year after year
 Cost of Doing Nothing
Once recommendations have been quantified the forgone savings start to accrue.
Previous Example:
Initial Cost: AED 500,000
Annual savings: AED 125,000
Lifetime 20 years

Company Profile

 Implementation of Energy Conservation Programme
Greenfield’s outstanding experience in Energy Conservation extends beyond Energy
Auditing and Benchmarking and into the actual implementation of the energy saving
measures. For this, Greenfield combines the project management and technical skills to
steer successfully an energy conservation programme through its entire process, which
typically involves the following stages.
 Preparation of tenders
 Selection of suitable energy saving equipment and contractors
 Procurement of equipment
 Supervision of installation of equipment
 Supervision of commissioning of equipment
 Measurement and Verification of the energy savings
 Energy conservation project management
Particular attention is paid to the correct installation and commissioning of the equipment,
followed by the Measurement and Verification process (M&Vs) to verify and measure the
actual energy savings in line with the calculated savings in the Energy Audit Report.
 Management of Energy Conservation Project
This is an additional service provided by Greenfield. Under this the energy conservation
activities of the project are managed after implementation of energy saving measures. The
minimum duration of this service is for one year and extending to any length of time as
decided by the client.
The core activities of this service are to ensure that;
 All energy saving equipment are functional
 The energy saving is achieved continuously
 Fine tuning of these equipment is done as required
 Timely maintenance of these equipment is carried out
 Monthly report on energy performance improvement is produced.
