Design and construction practices that meet specifiedstandards, resolving much of the negative impact of

buildings on their occupants and on the environment

Green building is the practice of increasing the efficiency withwhich buildings use resources energy, water, and materials

while reducing building impacts on human health and the

environment during the building's lifecycle, through better siting,

design, construction, operation, maintenance, and removal

A similar concept is natural building, which is usually on asmaller scale and tends to focus on the use ofnatural materials

that are available locally.

Other commonly used terms include sustainable design andgreen architecture.

GREEN BUILDINGS

Green building practices are:

environmentally responsible and resource-efficient to promote building practices that conserve energy and water

resources, preserve open spaces.

to minimise the emission of toxic substances

to harmonise with the local climate, traditions, culture and thesurrounding environment

to sustain and improve the quality of human life

maintaining the capacity of the ecosystem at local and global levels.

WHAT MAKES A GREEN BUILDING


10/48


11/48

The related concepts of sustainabledevelopment and sustainability areintegral to green building. Effective

green building can lead to : 1) reduced operating costs by

increasing productivity and usingless energy and water,

2) improved public and occupanthealth due to improved indoor airquality, and

3) reduced environmental impactsby, for example, lessening stormwater runoff and the heat islandeffect.

Practitioners of green building often

seek to achieve not only ecologicalbut aesthetic harmony between astructure and its surrounding naturaland built environment, although theappearance and style of sustainablebuildings is not necessarilydistinguishable from their lesssustainable counterparts.

EFFECTIVE GREEN BUILDING

Stormwateris a term used to describe water that originates

during precipitation events. It may also be used to apply to

water that originates with snowmelt or runoff water from

overwatering that enters the stormwater system.

Stormwater that does not soak into the ground becomes

surface runoff, which either flows into surface waterways or

is channeled into storm sewers

STORMWATER


13/48

An urban heat island (UHI) is ametropolitan area which is significantlywarmer than its surrounding rural areas.

The temperature difference usually islarger at night than during the day andlarger in winter than in summer, and ismost apparent when winds are weak.

The main cause of the urban heatisland is modification of the land surface

by urban development; waste heatgenerated by energy usage is asecondary contributor. As populationcentres grow they tend to modify agreater and greater area of land andhave a corresponding increase inaverage temperature.

Green building practices aim to reduce

the environmental impact of buildings.

Buildings account for a large amount of

land use, energy and water

consumption, and air and atmosphere

alteration.

URBAN HEAT ISLAND (UHI)

Green building brings together a vast array of practices and techniques toreduce and ultimately eliminate the impacts of buildings on theenvironment and human health.

It often emphasizes taking advantage of renewable resources, e.g., usingsunlight through solar energy, and using plants and trees through greenroofs, rain gardens, and for reduction of rainwater run-off.

Many other techniques, such as using packed gravel for parking lotsinstead of concrete or asphalt to enhance replenishment of ground water,are used as well.

Effective green buildings are more than just a random collection ofenvironmental friendly technologies, however. They require careful,systemic attention to the full life cycle impacts of the resources embodiedin the building and to the resource consumption and pollution emissionsover the building's complete life cycle.

GREEN BUILDING PRACTICES


15/48

On the aesthetic side of green architectureor sustainable design is the philosophy of

designing a building that is in harmony with

the natural features and resources

surrounding the site.

There are several key steps in designing

sustainable buildings:

specify 'green' building materials from local

sources,

reduce loads,

optimize systems, and

generate on-site renewable energy.

GREEN BUILDING PRACTICES


16/48

Green buildings often include measures to reduce energy

use. To increase the efficiency of the building envelope, they may

use high-efficiency windows and insulation in walls, ceilings,

and floors.

In addition, effective window placement (daylighting) canprovide more natural light and lessen the need for electric

lighting during the day. Solar water heating further reduces

energy loads.

Finally, onsite generation ofrenewable energy through solar

power, wind power, hydro power, orbiomass can

significantly reduce the environmental impact of the building.

Green architecture also seeks to reduce waste of energy, waterand materials used during construction.

For example, During the construction phase, one goal shouldbe to reduce the amount of material going to landfills. Well-designed buildings also help reduce the amount of wastegenerated by the occupants (in commercial buildings ) as well,by providing on-site solutions such as compost bins to reducematter going to landfills.

To reduce the impact on wells orwater treatment plants,several options exist. "Greywater", wastewater from sourcessuch as dishwashing or washing machines, can be used forsubsurface irrigation, or if treated, for non-potable purposes,e.g., to flush toilets and wash cars. Rainwater collectors areused for similar purposes.

Centralized wastewater treatment systems can be costly anduse a lot of energy. An alternative to this process is convertingwaste and wastewater into fertilizer, which avoids these costsand shows other benefits.

By collecting human waste at the source and running it to a

semi-centralized biogas plant with other biological waste, liquidfertilizer can be produced.

GREEN ROOF BUILDING


20/48

A green roofis a roof of a building that ispartially or completely covered withvegetation and soil, or a growing medium,

planted over a waterproofing membrane.

This does not refer to roofs which aremerely colored green, as with green roofshingles. It may also include additionallayers such as a root barrier and drainageand irrigation systems.

Traditional green roofs can be seen inmany places in the Faroe Islands. Green roof of city hall in Chicago, IIIinois

Green roofs are used to:

Grow fruits, vegetables, and flowers Reduce heating (by adding mass and

thermal resistance value) and cooling(by evaporative cooling) loads on abuilding

Increase roof life span Reduce stormwater run off

Filter pollutants and CO2 out of the air

The soil and plants on green roofs helpto insulate a building for sound; the soilhelps to block lower frequencies and theplants block higher frequencies.

Filter pollutants and heavy metals out ofrainwater

Increase wildlife habitat in built-up areas

BENEFITS OF GREEN ROOF BUILDING


24/48

Building materials typicallyconsidered to be 'green'

include rapidly renewable plantmaterials.

Example: bamboo (becausebamboo grow up quickly),

recycled stone, recycled metal,and other products that arenon-toxic, reusable, renewable,and recyclable, sheep wool,panels made from paper flakes,

clay, coconut and etc.Building materials should beextracted and manufacturedlocally to the building site tominimize the energy embedded

in their transportation.
