  1. SAINT GOBAIN Benefits From Energy Efficient Buildings Alghanim Industries Insulation Group Saudi First Insulation Manufacturing Co Alain DAVID Executive Advisor to the President

  2. How Is Building Energy Consumption Classified ? Most significant parameter for measuring energy in the building segment (kWh/m2.yr) Energy consumed per year kilowatt hour per year (kWh) = Per sq meters of living space m2. year (m2.yr)

  3. Energy Usage According To Climate Polar Climate Very cold & dry HEATING Mild Climate Warm and humid COOLING Tropical Climate Hot and humid Continental Climate HEATING Cold and humid Mountain Areas Altitude affects climate Very Hot Climate

  4. Saved Energy Is The Largest ‘Energy Resource’.

  5. Objective is to Reduce Building Cooling & Heating Energy

  6. First Step is to Achieve a Good Level Of Insulation Very Little Insulation Good Level Of Insulation Multi-Comfort-House CO2 = 90 kg/m²a Savings on cooling energy CO2 = 18 kg/m²a 16 cm 60 kWh/m²a 6 m³ gasor 6 liter oil 300 kWh/m²a 15 m³ gas or 15 liter oil 16 cm

  7. 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%.

  8. 150 100 50 0 Average Best present Passive Houses consumption in building code buildings How Much Can We Still Save ? 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%. kWh/m2/year for Heating Passive House: Steinbruchweg, Austria Sources: EU Commission DK building regulations and www.passivhaus.de Sources: Saint-Gobain Isover

  9. How Much Can We Still Save ? • 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

  10. 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.

  11. ASHRAE: American Society of Heating, Refrigerating and Air-Conditioning Engineers (www.ashrae.org) Building Codes of Practice in USA are Different for Each Region Minimum R-Value Map (Commercial) in USA: Zones 2 & 3 is hot and humid.

  12. Economy Growth From Energy Efficiency Aggressive increases in US building energy codes could result in • Increase of nearly 1.1 million US jobs • Increase in income of $28.5 billion US Source: the American Council for an Energy-Efficient Economy

  13. Our Assumption Of Typical Housing In GCC 8 m 10 m 15 m • 300 m² surface area • 1200 m³ volume

  14. How Much Insulation? 8 m 10 m 15 m • Typical house in Saudi Arabia: • 300 m² surface area • 524 m² with insulation

  16. More than 2 power plants More than 4 power plants Number of 1000 MW Power Plants Which can be Saved if Only 20 000 New Houses Were to be Properly Insulated From Now on

  17. Requirement of insulation product (incl stone wool): high compression strength and resistance to delamination One Option For Insulating A Building From The Outside • wall (concrete) • adhesive • insulation product • anchor • base coat • glass fibre mesh • base coat • key coat (opt) • finishing coat • base bar

  18. External Thermal Insulation Composite System (ETICS) Study in Kuwait Kuwait Institute for Scientific Research Study on Houses with different level of Insulation • Room Temperature Setting: 23C • Data Recording Hourly: Cooling Energy kWh

  19. Heat leak at corners / walls joins Poor door & window insulation Potential savings improvement expected after defaults correction Hot spot Observation Of Construction Defects – Potential For Even Higher Savings With Better Practices Even Beyond Those Reported Here ...

  20. Aug Jan Feb Mar Apr May Jun Jul Sept Oct Nov Dec Our Experience With KISR Based On Real Testing Houses - Preliminary Testing Results Interpretation. • Annual average 33% was obtained with 120 mm stone wool, better results expected after correction of construction defect and better glazing installation.

  21. Additional Benefits With Insulation.Important to Choose Insulation Contributing to Fire Protection and Safety • 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 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

  22. Choose Insulation Material Contributing to Fire Protection April 28th 2012: SHARJAH BUILDING FIRE 125 families ….at least +400 human beings .. Dubai: A new national fire safety code set to become law later this year may be revised to ban non fire-rated cladding panels on skyscrapers, Gulf News has learnt (May 10th, 2012)

  23. Additional Benefits With Insulation Outside wall surface temperature Inside wall Surface temperature Inside house set temperature Inside house Temperature difference • Lower cooling air flow noise • Lower installed cooler capacity • Less frequent start – stop from cooler • Little temperature differences inside house Wall structure 20 cm white Block 48°C 34°C 23°C 11°C 20 cm white block +16 cm Mineral wool 48°C 23°C 3°C 26°C Thermal comfort depends on far more than just air temperature—it also includes the environmental factors of mean radiant temperature (…), relative humidity, and air velocity (1).

  25. Thermal Insulation Can Also Deliver Acoustic Insulation Mineral Wool Provides Light Building System with High Sound Insulation STC MSM System - 60 kg/m² Thickness 220 mm STC = 67 dB ML - 600 kg/m² Thickness 260 mm STC = 65 dB • Mass-Law (ML) Single Layer Element 600 kg/m² • Mass-Spring-Mass (MSM) system 60 kg/m² • Metallic Building Acoustic Insulation Source: naima.org STC: Sound Transmission Class, an integer rating of how well a building partition attenuates airborne sound

  26. Additional Benefits With InsulationOne Of The Major and Cheapest Solution For CO2 Reduction

  27. 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 Flat walls for easy insulation of ETICS Default due to workmanship to be eliminated • Enforce all these practices for the energy savings, the fire safe, the acoustic insulation, the comfort of life as well as sustainability.

  30. Kuwait Ministry of Electricity and Water and GE Energy yesterday announced the signing of aturnkey contract thatwill help address the growing demand for power in the State of Kuwait. Kuwait: Monday, September 14 - 2009 As 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 helpmeet 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 outagesduring 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 powercapacity 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 developmentof Kuwait. GE's technological capability and strong local service support will help meet the need for responsible, efficient energy inKuwait," 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 firstphase will add 1,300 MW of capacity to the Kuwait electricity grid in 2011, with the second phase adding the remaining 700 MW in2012. 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.
