INTRODUCTION

Is this 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)

Minimum use of conventional energy

Utilization of green energy Reduction in water requirement

and waste

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

• Energy Efficiency

• Noise Reduction

• Fire-resistance

• Strength

• Prevention of mildrew rot

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.

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.
