"A green building is one which uses less water, optimises energy

efficiency, conserves natural resources, generates less waste

and provides healthier spaces for occupants, as compared to a

conventional building."

What is a Green Building?

Page 3: Presentation kuwait 24.05.12

The Blu Homes mkSolaire, a green building designed by Michelle Kaufmann

What is a Green Building?Green building (also known as green construction or sustainable building ) is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle:

• from siting to design,

• construction,

• operation,

• maintenance,

• renovation, and

• deconstruction

This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort

LEED points are awarded on a 100-point scale, and c redits are weighted to reflect their potential environmental impacts

Additionally, 10 bonus credits are available, four of which address regionally specific environmental issues. A project must satisfy all pr erequisites and earn a minimum number of points to be certified.

A second much more devastating fire at Animal Friends, Kuwait on 23rd

March 2010. This fire was in the main building and 39 animals perished. Several more are struggling to hold on. A skyscraper in Kuwait City

caught fire at around 3PM on 26 Feb, 2010

Three firefighters were injured were treated due to smoke inhalation while attending a fire that broke out at the project site for the New Doha airport in Qatar 0n12th September, 2010.

The cause of the blaze was suspected due to foam insulation.

Local reports state the fire damaged 30 portable cabins and 10 vehicles.

Some Recent Fire Incidents in GCC

Firefighters injured in Doha airport project blaze

� Fire broke out at the residential Al TayerTower near Al Nahda Park in Sharjah on Saturday morning at around 2:30am . Hundreds of families have been displaced.

� Firefighters battled for about five hours to control the flames that engulfed the building, witnesses said.

� The cause of the blaze was suspected due to combustible insulation panels used in the building.

Preference for an insulation material among the given

options shall be based on

• Usage of Raw material

• Handling, transportation and storage

• Application Requirement

• Safe to Human

• Throughout Life Performances (Aging effect)

• Emissions after in use

• Fire Class

• Behaviour during fire

• Impact on environment (ODP & GWP)

Page 27: Presentation kuwait 24.05.12

Let’s go with confidence !

By opting Mineral Wool Insulation (Glass wool & Rock wool)

Page 28: Presentation kuwait 24.05.12

Because Mineral Wool (Glass wool & Rock wool) Insulation

� Are available as flexible, semi rigid and rigid

� Are light in weight and compressible

� Are suitable in wide range of temperature from – 200 oC to + 800 oC

� Does not promote growth of mould, bacteria and fungus

� Does not show any aging

� Are Fire Safe; Resist the fire and achieve highest class of fire safety

(Euro Class A1)

� Can meet almost all application requirements in the building

� Are made from abundantly available raw materials (minerals) on the earth

And moreover “Buy one and get one free” rule is applicable due to their dual

performances ( Acoustic and Thermal Insulation)

� Environment Friendly – Zero GWP and Zero ODP
