INTRODUCTION

Green
Building


Green Building
Design and construction practices that significantly
•Reduce, or eliminate the negative impact of buildings on
the environment and its occupants with regard to site
planning;
• Safeguarding water use and water use efficiency;
•Promoting energy efficiency and renewable energy;
conserving materials and resources; and promoting indoor
environmental quality.”
•Extending the life span of natural resources
•Providing human comfort
•Safety and productivity
(US Green Building Council)


GREEN MATERIALS


Insulated Concrete Forms:
These preformed blocks are made
with expanded polystyrene (EPS)
and metal rebar which are be
stacked to build the frame. They
are then filled with concrete to
create an insulated and
exceptionally strong wall.

The Benefits of Building a Home
with Insulated Concrete Forms
• Noise Reduction
• Fire-resistance
• Strength to building


GREEN CEMENT
• It is produced by using mainly two materials fly
ash and cement kiln dust (CKD). These two
materials are industrial wastes. Both of these do
not produce CO2 or other green house gases and
thus is ecofriendly.
• If the two materials are appropriately blended, the
alkalis from cement kiln dust may Activate
hydration of fly ash, and the blends may create a
cementitious material in which the waste material
deficiencies will be converted into benefits.


CAVITY WALLS
• Cavity walls consist of two
'skins' separated by a hollow
space (cavity). The skins are
commonly masonry such as
brick or concrete block.
• They provide better sound and
heat insulation and most
importantly resistance to rain
penetration.
• The major products used for
insulation between the two
walls are:
– Rigid foam board
– Rigid fiber board
– Spray Polyurethane foam


GREEN FIBRES
• Substitute glasses by green fibers or
ecofriendly glasses, recycled glasses for
window panes and all other places of glass
usage.
• Use recycled glasses to have reduce harm to
the environment caused by glass industries.


GREEN WOOD
• Green wood is made by pressing together
hemp fibers, which are available readily and in
plenty with bio-degradable plastics at a high
temperature.
• When the building is demolished or renovated
for any purpose, this green wood can be
directly sent to landfills and thus is harmless
to the environment.


Green Paint
• Traditional household paints contain many
chemicals, including volatile organic compounds
(VOCs), including benzene, formaldehyde, and
toluene, which are a large group of carbon-based
chemicals that are volatile, meaning that they
like to exist as a gas.
• Some of these VOCs have been linked to bad
health outcomes, including eye, nose and throat
irritation, nausea, headaches, and even cancer.


Feasible Green Technologies
• Solar Photovoltaic
• Wind Energy
• Solar Thermal, Improved Water Mill,
Geothermal Energy


Solar Photovoltaic
• Converts sunlight into electricity
using semi conductor modules.
• Used generally for meeting
lighting requirements, they can
also be used for pumping water,
refrigeration, communication, and
charging batteries.
• Solar photovoltaic has application
as green agricultural energy
source for pumping water street
lighting in villages, lighting in
rural houses and pest management
• The high –powered devices
produce no waste or pollution.Pirpasha Ujede

Wind Energy

• Wind energy is in a boom
cycle. Overall, wind energy
contributes only 1% of
global electricity generation.
Its importance is increasing
in the sense that
comparatively with other
sources; the wind energy
produces less air pollutants
or greenhouse gases.
