2. WHAT ARE ENERGY EFFICIENT
BUILDINGS?
oBuildings which are designed to provide a significant reduction of the
energy need for heating and cooling, independently of the energy and of the
equipment that will be chosen to heat or cool the building.
oBuildings which are very less dependent on conventional methods for its
energy fulfilment
oBuildings which complete there energy requirement by self either by its
construction technologies or by self energy producing units using renewable
energy resources.
3. ENERGY REQUIRMENTS OF
BUILDING
oEnergy required to produce traditional construction material
oEnergy required in construction process
oEnergy requirements of building after construction
4. BUILDING ENERGY USE IN
INDIA
oThis use includes residential and commercial lighting, appliances, heating
and cooling. The overall building energy use consumes 37% (i.e 213 Mtoe) of
India’s total annual primary energy consumption.
oIndia has been responsible for almost 10% of the increase in global energy
demand since 2000
oThe primary energy demand in India has grown from about 441 Mtoe in
2000 to about 775 Mtoe in 2013.
oThis demand is expected to increase to about 1250 (estimated by
International Energy Agency) to 1500 (estimated in the Integrated Energy
Policy Report) million toe in 2030.
othere will be approximately 860 percent increased electricity consumption in
buildings (from 238 TWh/year to 2,287 TWh/year) by 2047
5. METHODS TO ACHIEVE ENERGY
EFFICIENCY
oBioclimatic architecture: shape and orientation of the building,
solar protections, passive solar systems
oHigh performing building envelope: thorough insulation, high
performing glazing and windows, air-sealed construction,
avoidance of thermal bridges
oUse of advance and sustainable building materials: straw bales,
plant-based polyurethane foam, fly ash etc.
oSelf electric energy generation: active solar systems, wind
turbines etc.
6. BIOCLIMATIC ARCHITECTURE
Refers to the design of buildings and spaces (interior – exterior – outdoor) based on
local climate, aimed at providing thermal and visual comfort, making use of solar
energy and other environmental sources.
9. HIGH PERFORMING BUILDING
ENVELOPE
The building envelope includes all the building components that separate the
indoors from the outdoors. Building envelopes include the exterior walls,
foundations, roof, windows and doors.
12. ADVANCE AND SUSTAINABLE BUILDING
MATERIALS
Traditional construction materials consume more energy in their production as
well as in their use in construction at the same time gives adverse effect on
environment.
Opting advance and green construction material not only reduces the energy
consumption but also give sustainable solutions to construction industry.
Buildings constructed with these material are more energy efficient and
environment friendly.
In most of the cases these building materials are low cost (as produced from
waste) and gives low cost construction solutions.
13. ADVANCE AND SUSTAINABLE BUILDING
MATERIALS
Plant-Based Polyurethane Foam
Plant-based Polyurethane Rigid Foam can be used in insulation
Manufactured from materials like kelp, hemp, and bamboo
highly resistant to moisture and heat
It even offers better insulation and thermal resistance than fiberglass.
Straw Bales
Straw bales are made from a agricultural waste product
Straw bale insulation is the most effective in climates where heating
and/or cooling of the home is essential for comfort
Straw bales have a low-embodied energy
Low-E Glass
Low E applied to windows helps block infrared light from
penetrating the glass from the outside
Low E Windows Reduce Destructive UV Rays. These coatings
help reduce ultraviolet (UV) light.
Low E Windows Reduce Energy Costs
14. ADVANCE AND SUSTAINABLE BUILDING
MATERIALS
GrassCrete
Environment friendly
concrete that infuses grass into it to create an open pattern of grass and concrete.
Optimal drainage capability
HempCrete
Hemp is the only building material that can
remove carbon from the air
Hempcrete stores heat in the thermal mass of its wall
which is then released slowly as the building cools down.
Hempcrete is a bio-composite material that contains a mixtures of hemp, hurds and lime
Bamboo
Environmentally Friendly
Durable and strong
Affordable
15. ADVANCE AND SUSTAINABLE BUILDING
MATERIALS
Recycled Plastic
it is less expensive than most other materials
reduces greenhouse gas emissions
Mycelium
comprises the root structure of fungi and mushrooms.
Mycelium composites are manufactured using a low-energy
Source of good isulation
Ferrock
Ferrock is created from waste steel dust (which would normally be thrown out) and silica
absorbs and traps carbon dioxide as part of its drying and hardening process
carbon neutral
Solar tiles
Solar tiles are almost invisible
Solar tiles work just like panels to provide you with clean, free energy
Solar tiles are even more durable than traditional, bolt-on panels
16. SELF ELECTRIC ENERGY GENERATION
TO INCREASE ENERGY EFFICIENCY OF BUILDING AND TO MAKE IT LESS DEPEND ON
CONVENTIONAL ENERGY SOURCES ELECTRIC AND THERMAL ENERGY CAN BE DEVELOP IN
BUILDING ITSELF WITH THE HELP OF SOLAR AND WIND ENERGY.
Solar Energy
Solar energy is simply the light and heat that come from the sun.
People can harness the sun's energy in a few different ways:
Photovoltaic cells, which convert heat from the sun in to
electricity. Solar thermal technology, where heat from the sun is
used to make hot water or steam.
The principal advantage of solar energy: Nearly everyone can
adopt directly
Fulfill your social responsibility to reduce carbon emissions
Help cut your electricity bill and save money
Enhance the resiliency and reliability of the electricity supply
Long-time warranty and low maintenance costs
17. SELF ELECTRIC ENERGY GENERATION
Wind Energy
Wind energy (or wind power) describes the process by
which wind is used to generate electricity. Wind turbines convert
the kinetic energy in the wind into mechanical power. A generator
can convert mechanical power into electricity.
Wind turbines can be installed near around the building or in
building to fulfil self energy goals. Eg- IIT Pallikad, Bharain World
Trade Centre etc.
Free Fuel
One of the Cleanest Forms of Energy
Reduces Our Dependence on Fossil Fuels
Wind Energy has Low Operating Costs
18. ZERO ENERGY BUILDINGS
Zero-energy building (ZEB), also
called Net zero-energy building are
combine energy efficiency and self
energy generation to consume only as
much energy as can be produced onsite
through renewable resources over a
specified time period.
Zero-energy buildings (ZEBs) usually
use less energy than traditional
buildings
generate their own energy on-site to
use in the building
many are independent from the
national (electricity) grid
