Necessity of green building
Recourses ,water and energy are dwindling (getting reduced year by year) to give way to building
Resources---(forest ,ground cover) etc are destroyed to provide structure to a building
Energy is getting utilised highly for lighting ,air conditioning and water heating
Water is getting utilised continuously during building construction and operationSlide3
Several building processes and functions of occupant function produces large amount of wastes
Building also affect urban air quality and contribute to climate change
Design and Construction of green building is costlier as compare to other building
But maintenance of green building is costlier
Slide4
Definition of green building
“
These are the structures that ensure efficient use of natural resources like building materials ,water and other energy with minimum generation of non-degradable wastes”
Technologies like efficient cooling system and sensor system that can sense the heat generated with from human body and automatically adjust room temperature and reduce energy consumptionSlide5
Technologies like air based flushing systemUse of CFL’s and LED’s instead of conventional incandescent lampsSlide6
Green building comprises of.........Slide7
Points to be considered while design of green building
Site planning
Building envelop design
Building system design (HVAC) lighting ,electrical ,water heating)
Integration of renewable energy sources to generate energy on site
Water and waste management
Selection of ecologically sustainable material(with high recycled content and rapidly renewable resourcesSlide8
Benefits of green building
Green building has low resource consumption as compared to conventional buildings
Following are the different percentage reduction of various energy resources
green buildings consumes 40%to 60% less electricity as compared to conventional building
It generates renewable energy utilization to cater to its energy needsSlide9
To be continued...........................
i
)Solar thermal energy can be used to generate hot water
ii)solar PV panel to create electricitySlide10
To be continued...........................
3. Green building consumes 40-80% lesser water as compared to conventional building (by utilizing ultra low flow fixtures dual plumbing system ,waste water recycling system ,and rain water harvesting )
4.Green building generates less waste by waste management strategies
5.Green building produces less pollution both during construction as well as in use.Slide11
To be continued...........................
6.Green building restricts the use of high Ozone depletion Potential substances in their system as well as in finishes.
7.Green building ensures proper safety ,health and sanitation facilities for the labourers and the occupantsSlide12
Building materials use in Green building
Slide13
To be continued...........................
Green building uses:-
Bamboo board as green material
Wood fibre from paper wasteSlide14
To be continued...........................
Ensure that the embodied energy of materials used for construction is low
It should have zero (low off) gassing of harmful air emission
Low toxicity
It should have high recyclable strength ,durability and long lasting
It should be locally produced i.e. It will promote the resource conservation and efficiencySlide15
Features those are considered for planning and design of buildingSlide16
Green building rating system
Major rating system that are used through out the world are:-
BREEAM
-(Building Research Establishment Environmental Assessment Method
GB Tool-
(Green Building Challenge Assessment Framework)
LEED
-Leadership in Energy and Environmental DesignSlide17
BREEAM
logo
Recognised by.........
UK
Australia
CanadaSlide18
LEED
Logo
Developed by...............
US Green Building Council 2000
Popularly known as LEE D rating system
Widely accepted rating system due to its simplicitySlide19
G B Tool
Points to noted.......
More than 20 counties committed for the development of this rating system
Popularly known as
GBTools
Recognised in......
Korea
Italy
BrazilSlide20
LEED concentrate on the following 5aspects in building design and life cycle performanceSlide21
LEED
For each aspect pre-requisites and credits are provided
Credits can be achieved when the building design meets or exceeds the requirement depending upon performance level achieved
Depending upon the credits or total points accrued ,Label or certificate is issued recognizing the green buildingSlide22
Green building certification in India
There are 3primary rating system in India
GRIHA-Green Rating For Integrated Habitat Assessment
IGBC-Indian Green Building Council
BEE-Slide23
GRIHA-Green Rating For Integrated Habitat Assessment
GRIHA Is India’s own rating system developed by TERI(The Energy Research Institute) and the Ministry of New and Renewable Energy
The process initiates with the online submission of documents as per prescribed criteria followed by on site visit and evaluation of building by team of experts from GRIHASlide24
GRIHA includes34 criteria in 4 different sections
Site selection
Conservation an efficient utilization of resources
Building operation and
maintenece
InnvoationSlide25
IGBC-Indian Green Building Council
Confederation of Indian Industry(CII)formed Indian Green Building Council in 2001
It is a non profit research institution having its office in CII
It has licensed the LEED Green Building Standard from the USGBC
It facilitates the Indian green structure to become one of the green BuildingSlide26
Environmental friendly ,Non toxic paints
All paints contains main components
Pigments(colour)---cadmium, lead Chromium
Binder (holds the paint together)
Carrier(disperses the binder)
Petrochemicals ,solvents ,benzene formaldehyde etc used as binders and carriers
VOCs (organic Chemical compounds)—evaporates easily in atmosphere and known to be major contributor to the global climate changeSlide27
Eco –labels for paints
Non toxic paints are called Low VOC ,No-VOC ,VOC Free, Odourless ,Odour free and green
These eco labels are found as logo on paint cans and include the European Eco-Labels, Blue Angle in Germany and Green seal and Green Guard in USASlide28
Natural paints
These are only true non toxic paints since they contain no VOCs
Ingredients are water, vegetable oil ,Plant dyes ,natural minerals
Binder used are: linseed oil(flax seed) clay ,lime and milk protein
Turpentine is used as solvent—distilled from pine trees
Essential oil from citrus fruits ---as solvent and for fragranceSlide29
Benefits of natural paints
Non Toxic:-
No Hazardous fumes or harmful effect on health, significant for allergy sufferers and chemically sensitive people
Environmentally Friendly:-
use renewable resources ,are biodegradable, can be composted
Micro-Porous:-
prevents condensation and damp problem, less prone to paint flaking ,peeling & blisteringSlide30
Green roofing
Green roofs are those planted with specific vegetation using well researched sustainable design methodology
It is an exciting new development in the sustainable building movementSlide31
Components of green roofing are
Components are........
Water proof layer
Roof repellent membrane
Filter cloth to drain the water
Moisture blanket
Drainage system
Soil substrates
Typical layout of green roofSlide32
Living roofs
It is designed to grow native plants
It encourage a wide range of important wild life including insects species such as butterflies ,bees ,local birds etcSlide33
Types of green roofs
Intensive living roof
Extensive living roofSlide34
Types of green roofs
(both are used for pitched roof construction)
Include plants of 1-15feet high
