Climates, Orlando, FL, July 24-26,
2006

Due to heavy use of air conditioning,
reliance on desalination for water,
and highly subsidized electricity
prices, Kuwait's per capita electricity
consumption is amongst the highest
in the world.

ENERGY CONSERVATION PROGRAM IN KUWAIT: A LOCAL PERSPECTIVE
Ali E. H. Hajiah, PhD; Kuwait Institute for Scientific Research

In Kuwait, nearly 300-350 MW
power is added every year only to
satisfy the growing demand of the
A/C systems


Kuwait
• Seven months of summer
• Temperatures over 50 C.
• “Air-conditioning of buildings is the single
largest consumer of electricity and accounts
for nearly 75% of nation’s peak power
demand and over 50% of annual energy
consumption. “


• MEW is spending nearly 80 million
Kuwaiti Dinars at 400 KD/kW every year
to add additional power generation and
distribution.

• The amount spent annually on fuel to
generate electricity for the operation of
the A/C systems is well over 90 million
KD (MEW, 2002).


• Power demand is expected to continue
increasing at 7-9 percent a year, necessitating
construction of new generating capacity.

• According to government estimates, roughly
$3.6 billion in further investment is needed by
2010.

September 14, 2009

GE Energy announced that the Kuwait Ministry
of Electricity and Water signed a $2.65 billion
USD contract for a new power plant

Kuwait’s robust business and residential growth
has strained the country’s power generation
capability, resulting in power outages during
the hot summer months.

From the Energy Information
Administration:

Kuwait seeks to significantly increase
its use of natural gas in electricity
generation, water desalination, and
petrochemicals to free up as much as
100,000 barrels per day of oil for
export.

http://www.eia.doe.gov/emeu/cabs/Kuwait/Full.html

Kuwait Consumption & Imports

In 2006, an annual basis - natural gas consumption
matches production.

Kuwait’s electricity demand, has outpaced natural
gas production during the summer months.

Result is the shutdown of refinery and
petrochemical operations to meet the increased
demand in electricity.

http://www.eia.doe.gov/emeu/cabs/Kuwait/Full.html

By 2014 regional energy demand is
forecasted to have a 25.1% growth over
the period since 2009.

Kuwait's thermal power generation is forecast to rise 70.2% between 2009 and 2019

Heat Transfer

Where there is a temperature difference
between objects in proximity, heat transfer
between them can never be stopped; it can
only be slowed down.

SOLAR RADIATION
Infrared (thermal) heat rays travel…

•With the greatest intensity
perpendicular to the surface.

•With the least intensity parallel with
the receiving surface (zero intensity).

SOLAR RADIATION
Radiation Exposure
• A 7 story building is exposed to more radiation on
the walls than on the roof.

• A single story building receives 70% of it’s solar
radiation on the roof.

Environmental Factors

Cannot be manipulated:

• Ambient air temperature
• Solar radiation
• Wind

Building Material Factors

Can be manipulated:

• Material resistivity (r-value)
• Surface Solar reflectivity
• Surface Solar absorptivity
• Surface Thermal radiation emissivity

Heat Transfer and Buildings

The best way to reduce heat transfer:

 Prevent it from entering the building.

The best way to manage heat transfer:

 Re-emit it quickly.

Solutions That Require
Large Scale Investments

Kuwait Declaration

• Calls for…
 taking the necessary procedures to preserve
environment & natural resources, & the optimal
use of it to achieve sustainable development.
 …and take action to limit the impact of climate
change & its repercussions on Arab societies.

History
• In 1995, the Kuwait Environment Public Authority (EPA) was created.

• With the help of the ESCWA (the Economic Commission for Western Asia
(ECWA) in 2005 set forth an environmental strategy with three types of
objectives:

 the reduction of the rate of pollution;
 introduction of the environmental dimension in policies, plans and
national programs;
 the protection of the national resources and the biodiversity in the
context of sustainable development. (LEED)

“The adoption of such strategies can hardly be considered as a luxury in all Gulf countries;
in which environmental problems are somewhat similar”.

http://www.escwa.un.org/divisions/pptcdadvisors.asp?id=12

Questions
Can Kuwait avoid the need to build new power plants?

Can economic competitiveness be increased?

Can health conditions be improved ?

Can building maintenance and operation costs be
decreased?

Can green house gas emissions be reduced?

• Many buildings are eligible for improvements
completed within the normal course of
business.
• For municipal buildings, benefits are passed
through to the primary designers/architects in
an attempt to encourage innovative municipal
design.

• Cool roof standards are designed to reduce a/c
demand, save money, and save emissions.

• In Los Angeles they will eventually save $100,000
per hour.

• Each 25m2 of cool roof offsets 1 ton of CO2

REDUCE PEAK DEMAND

A reflective roof can reduce peak
cooling demand by 10-15%.

Net Savings

• Since 2005 California has required most flat-
roofed buildings to be white.

• 75% of Wal-Mart stores in the US have
installed “cool roofs”.

• Washington, D.C. will require new flat roofs on
commercial buildings to be covered in
vegetation or a reflective material.

Hashem Akbari

"It buys us precious time" to figure out
ways to limit greenhouse-gas emissions or
remove the gases from the atmosphere. “

"It basically buys us time until we come up
to our senses."

1998 US established the
Cool Roof Rating Council

First products rated in 2003.

2009 EU established its Cool

What is the difference between a
paint and a coating?

Paint: An aqueous liquid continuous film applied at
film thickness' of less than 10 wet mls.
Coating: An aqueous liquid continuous membrane
applied at film thickness’ greater than 40 wet mls.

Benefits of
Acrylic Roof Membrane
vs.
Paint
Remain Flexible
Resist standing Water
Excellent Adhesion to a variety of substrates
Resist UV exposure
Applied at greater film thickness for increased flexibility
Resistance to Foot Traffic…tensile strength
Higher Reflectivity and increased emissivity

Definition of an
Advanced Roof Coating

An aqueous liquid suspension, applied to roofing
substrates, which dries to a seamless, resilient,
durable membrane which is flexible across a
broad temperature range.

What is the
difference in coatings?

White coatings have good solar reflectance, but…..
 Chalks, talc and clay can be added to make the
coating white and increase solid content.
 They have a higher rate of erosion over advanced
roof coatings using titanium and ceramics.
Ceramics dramatically reduce erosion.

 Premium resins are superior for adhesion,
flexibility and durability.

So what makes a quality
Roof Coating?
Binder
Volume Solids
PVC

High Quality Coating Lower Quality Coating

Pigments Pigments

Resin Resin less
60% or than 50%
