Fifteenth Symposium on Improving Building Systems in Hot and Humid Climates, Orlando, FL, July 24-26,

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 by Mike Kinghttp://www.pr-inside.com/kuwait-s-thermal-power-generation-is-r1724985.htm

Buildings account for…

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 RADIATIONSOLAR RADIATION

• 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.

Radiation Exposure

SOLAR RADIATION

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

• 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.

Kuwait Declaration

http://www.da.gov.kw/eng/articles/arab_economic_summit_2009_speeches.php?p=summit_declaration

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

QuestionsCan 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?

"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 theCool Roof Rating Council

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.

What is the difference between a paint and a coating?

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

Benefits of Acrylic Roof Membrane

vs. Paint

An aqueous liquid suspension, applied to roofing

substrates, which dries to a seamless, resilient,

durable membrane which is flexible across a

broad temperature range.

Definition of an Advanced Roof Coating

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.
