2. What is a Green Building?
"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."

3. 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 The Blu Homes mkSolaire, a green building
designed by Michelle Kaufmann
This practice expands and complements the classical building design
concerns of economy, utility, durability, and comfort

11. LEED points are awarded on a 100-point scale, and credits 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 prerequisites and earn a minimum
number of points to be certified.

12. 100 Possible Points + 10 Possible Points

26. 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)

27. Let’s go with confidence !
By opting Mineral Wool Insulation
(Glass wool & Rock wool)

28. Because Mineral Wool (Glass wool & Rock wool) Insulation
Are made from abundantly available raw materials (minerals) on the earth
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)
Environment Friendly – Zero GWP and Zero ODP
Can meet almost all application requirements in the building
And moreover “Buy one and get one free” rule is applicable due to their dual
performances ( Acoustic and Thermal Insulation)
