Very Little Insulation Good Level Of Insulation
First Step is to Achieve a Good Level Of Insulation
How To Achieve This?
Increase insulation in housing by installing an envelope of insulation, and better on outer wall to improve thermal inertia of cooled walls inside which will allow easily the reduction of energy consumption for air conditioning by more than 50%.

Even after using insulation to bring the energy consumption from 300 kWh/(m2.yr) down to about 140 kWh/m2/year, it is still possible with existing and proven technology to reduce the energy consumption by more than 80%.

Passive Houses
• Design housing as below :– Improve air-tightness of buildings to prevent hot air
from entering the building.– Improving glazing frames to reduce thermal
bridges.– Manage heat exchange between outgoing colder air
and incoming hot air with mechanical ventilation system.
• KSA climate limits the use of– Night ventilation factors– Therefore, KSA houses will always have a small cooling
load to be managed but we can still approach the passive house standard
How Much Can We Still Save ?
Buildings Under Construction In GCC
• It appear that new houses under construction in GCC are not properly insulated. We are seeing this situation in Kuwait where R is 10 for the walls and R is 13 for the roof according to the Kuwait Building Code of Practice.
• In fact ,we calculated the R value for the walls and find out that it was only 7.2 due to conduction through concrete beams (55% white blocks, 25% concrete beams and 20% windows / door).
• There is a clear need for more insulation, and therefore for stringent Building Code of Practice.

Additional Benefits With Insulation.Important to Choose Insulation Contributing to Fire Protection and Safety
Stone wool is by nature not combustible and remains so for the life of the product without the addition of harsh and potential dangerous chemical fire retardants.
Passive fire protection in many buildings such as 2 hours fire rating required fire stop
Euroclasse:– A1 or A2 (non combustible)– s1 no smoke– d0 no droplets and particles
BS 476 (parts 6 & 7): Class 0
ASTM E84 as to Surface Burning Characteristics:– Fire Spread Index:
< 25– Smoke Development Index:
< 50

Additional Benefits With InsulationOne Of The Major and Cheapest Solution For CO2 Reduction
What Can We Do In GCC and in Particular in KSA
• Make public buildings energy efficient role models
• Provide one-stop energy efficiency packages for new construction
• Always make building renovations energy efficient using intelligent incentives
• Start with ETICS and more roof insulation (R-value at 24) for easy application including the existing houses since all walls are basically flat
• Ensure good quality of workmanship• Enforce all these practices for the energy savings, the fire safe, the acoustic insulation, the comfort of life as well as sustainability.
Flat walls for easy insulation of ETICS

Kuwait signs $2.65bn electricity agreement to boost power capacity
Source: www.ameinfo.com
Kuwait Ministry of Electricity and Water and GE Energy yesterday announced the signing of a turnkey contract that will help address the growing demand for power in the State of Kuwait.
Kuwait: Monday, September 14 - 2009As per the $2.65bn contract, GE and Hyundai Heavy Industries will develop a
new, 2,000-megawatt (MW) power plant in Sabiya. The Government of Kuwait-owned plant will add much needed power to the grid, allowing Kuwait to boost electricity production to help meet growing demand. When completed, the plant will raise Kuwait's power capacity from current levels of around 11,000 megawatts. Kuwait's robust business and residential growth has strained the country's power generation capability, resulting in power outages during the hot summer months.
"This will be the largest combined cycle power plant in Kuwait and it is an important step in our plans to boost power capacity to meet continuing demand, which is projected to grow at about 8% a year,“ said His Excellency Dr. Bader Shabeeb Al Shriaan, Kuwait's Minister of Electricity and Water.
"A reliable supply of electricity is critical to avoid future power shortages and to support the continued economic and social development of Kuwait. GE's technological capability and strong local service support will help meet the need for responsible, efficient energy in Kuwait," he added.
….GE will begin shipping equipment by the middle of 2010. The Sabiya power
plant is scheduled to come on line in two phases. The first phase will add 1,300 MW of capacity to the Kuwait electricity grid in 2011, with the second phase adding the remaining 700 MW in 2012. Primary fuel will be natural gas, with distillate as a backup. The gas and steam turbines will be manufactured at GE facilities in the USA.
