4. GREEN ARCHITECTURE
Green architecture, or green design, is an approach to building that
minimizes harmful effects on human health and the environment
What is a green building?
Green building (also known as green construction or
sustainable building) refers to both a structure and the using of
processes that are environmentally responsible and resource-
efficient throughout a building's life-cycle: from siting to design,
construction, operation, maintenance, renovation, and demolition.
• Efficiently using energy, water, and other resources
• Protecting occupant health and improving employee productivity
• Reducing waste, pollution and environmental degradation

5. CHARACTERISTICS
• Ventilation system are designed for efficient heating
and cooling.
• Energy efficient light and appliances
• Water saving plumbing fixtures.
• Non synthetic, non toxic materials.
• Adoptive re-use of old buildings.
• Alternate power source like solar and wind power.
• Roof garden
• Waste water recycling & Rain water harvesting.
• But the main goal of green building is to be fully
sustainable

6. SUSTAINABLE BUILDING FEATURES
• Natural ventilation.
• Solar power generation.
• Waste water recycling for cooling tower.
• Rain water harvesting.
• Geo thermal technology for heat rejection of AC system.
• Design inside temperature 26 deg c.

7. ADVANTAGE OF GREEN BUILDING VS. CONVENTIONAL BUILDINGS
•Cost savings(first cost saving; ongoing operating expense reductions)
•Minimize impact on environment
•Enhanced health and productivity of occupants
•Community and social benefits other owner benefits

8. Example of sustainable high-rise

•Bosco Verticale is a pair of residential towers in Milan, Italy
•absorb CO2 and dust particles, producing oxygen and protect the
building from radiation and acoustic pollution.
•moderate temperatures in the winter and summer.
•attenuate noise
•The steel-reinforced concrete balconies are designed to be 28 cm
thick, with 1.30 metre parapets
•the vegetation is the equivalent of that found in a one hectare

9. RELATIONSHIP WITH TALL BUILDINGS
 The skyscrapers erected do not compete with global implementations in the unfolding race of height and
their prestige is decided by, among other things, bioclimatic solutions.
 One of the key issues in the design of a tall, bioclimatic building, is the proper
 structuring, as well as the technical and technological solution of the elevation.
 The desired goals are: to maximize access to daylight and use of natural ventilation heating and
cooling, to minimize heat gain or loss and to prevent glare
Architecture that has a connection to Nature. Building designs that take into account climate and
environmental conditions to help achieve optimal thermal comfort inside. It deals with design and
architectural elements, avoiding complete dependence on mechanical systems, which are regarded as
support.
BIOCLIMATIC ISSUES/ BIOCLIMATIC ARCHITECTURE

10. PRINCIPLES:
• The consideration of the weather, hydrography and
ecosystems of the environment
• The efficacy and moderation in the use of construction
materials, giving priority to low energy content compared to
high energy.
• The reduction of energy consumption for heating, cooling,
lighting and equipment, covering the remainder of the claim
with renewable energy sources.
• The minimization of the building overall energy balance,
covering the design, construction, use and end of its life.
• The fulfillment of requirements of hygro-thermal comfort,
safety, lighting and occupancy of buildings.

11. Examples:
Education Executive Agency and Tax Offices
 The object was formed with the use of a
parametric methods in a way to obtain
optimal exposure to sun rays of the
interiors
 Enable natural ventilation through
windows.
 A smooth, bionic form was shaped as a
result of the aerodynamic analysis, the
aim of which was to minimize turbulence
around the building
 The facade which combines all the
necessary features of a bioclimatic
“skin” using a relatively simple
technology
 The characteristic elements of the
elevation are horizontal ribs,
surrounding the building at the ceiling
level.

12. ENERGY EFFICIENCY
What is energy efficiency?
Using less energy to accomplish the
same amount of work. Getting the
most work per unit of energy is often described as a
measure of energy intensity.
Common metrics for buildings and neighborhoods
include energy use per square foot and use per capita.

13. Why is this important for buildings?
 Studies have repeatedly shown that efficient buildings and appropriate
land use offer opportunities to save money while reducing
greenhouse gas emissions.
 Though estimates regarding the remaining quantity of these resources vary, it
is clear that the current reliance on nonrenewable energy sources is not
sustainable and involves increasingly destructive extraction processes,
uncertain supplies, escalating market prices, and national security
vulnerability. Accounting for approximately 40% of the total
energy used today, buildings are significant contributors to
these problems.

14. The psychological benefits :-
 using natural lighting sources,
including making a home or office more
comfortable, increasing worker
productivity, or making a retail store
more appealing to customers.
A study by the Rocky Mountain Institute showed
that in efficient buildings, labor productivity
rises by 6-16% due to the office being quieter,
more comfortable, and with better air and
lighting.

15. Different way to make a building ENERGY EFFICIENT :-
a. Using NATURAL source of energy.
b. Reuse of ENERGY.
c. Energy efficient (mechanical) devices.

16. Solar Power
The sun is the most reliable, renewable
and clean energy source we have,
so it’s amazing to me that more people
don’t use solar power. Not only can you
use PASSIVE SOLAR DESIGN to heat
and cool your house more efficiently, but
you can generate your own heat and
electricity using photovoltaic.

Solar Farm
a. Use of NATURAL source:-

17. Rain water HARVESTMENT
 Rainwater harvesting is a technique
used for collecting, storing, and
using rainwater for landscape
irrigation and other uses.
 With rainwater harvesting your rainwater
is collected in a water storage tank or
cistern and stored for later use.
 The Best Way To Reduce Water
Use In High-Rise Buildings

18. Geothermal
Often people have the idea that GEOTHARMAL
ENERGY, can only be harnessed in geologically
active regions of the world such as Iceland, Italy and
California.
 We can drill down into the earth, can
heat up water, creating a clean, efficient
energy source for heating and
cooling your home, completely bypassing the
whole need for boilers, furnaces and all that
jazz..
 In 1993, the Environmental Protection Agency
proclaimed geothermal heat pumps – aka
“ground-source heat pumps” – to be
the most energy-efficient,
environmentally friendly and cost-effective
residential heating system available.

19. Wind Power
The idea is simple: rotating turbine
blades gather kinetic energy
from the wind, spinning an internal
shaft that generates power. This process is
incredibly clean, producing zero
emissions.
Wind power is blowing up right now.
According to the Earth Policy Institute,
“Wind is the world’s fastest-growing
energy source with an average annual
growth rate of 29 percent over the last
ten years.”

20. Wastewater treatment
Wastewater treatment is a process used to
convert wastewater- which is water no
longer needed or suitable for its most recent
use - into an effluent that can be either
returned to the water cycle with
minimal environmental issues or reused.
b. REUSE of energy:-

21.  1. Let the sun shine.
 2. take advantage of daylight.
 3. Consider a fresh coat of light-colored paint and replace
those depressing yellowed ceiling tiles. It will improve
daylight and make your people feel better about coming
to work.
 4. Take control. Lighting and HVAC controls.
Install light switches with built-in occupancy and/or
daylight sensors in every room. Buy task
lights so you don't have to turn on those stadium lights
just to work quietly at dusk.
c. Use of ENERGY efficient device:-
Some steps to make building ENERGY EFFICIENT,

22. c. Use of ENERGY efficient device:-
 5. use of ENERGY SAVING DEVICES; like energy saving light
 7. Retrofit windows. We can now apply practically clear retrofit films to existing windows and
achieve nearly 50 percent heat rejection -- both keeping it in and out, depending on the
season.
 8. Seal ducts. Recent studies indicate that leaking ductwork is one of the primary construction
defects in both commercial, with common repercussions resulting in 10-25 percent leakage in
commercial buildings.

23.  The tower's entire facade will be replaced with an
animated LED façade.
 improved indoor comfort and
additional day lighting .
 and got a stellar green renovation and a
high performance office tower.

24. CUTTING EDGE
Cutting edge is an adjective used to describe the newest, most advanced version of a
product or service. In architecture new product and system are used rapidly now a days. This
whole new thing is address as cutting edge.
In architecture the newest technologies which is used in designing can be defined as cutting
edge. There are various types of cutting edge technology.
•Air condition
•Wind turbine
•Window coating
•Sensor system
•Operable façade
•Healthy material
•Cultivated façade
•Precast constructions etc…

25. • Double glazing.
• Adding layers means additional thickness and weight.
• Thinner krypton gas filled cavities, vacuum glazing units, closed cavity facades, and heat
reflecting films.
• Heat mirror films is a Solar Responsive Thermo chromic (SRT) adaptive glazing film which uses
the sun’s energy to cause the tinting of the window, naturally controlling room
temperatures.
• Air-conditioning system is almost always defined by the glazed area and while dark tinted
windows and reflective coatings are used to reduce the Solar Heat Gain Coefficient (SHGC) of
windows.
Frames:
• Window frames are a common source of thermal bridging. Particularly in commercial applications where
better thermal dampener variations such as timber and vinyl frames are not applicable to use and
aluminium frames dominate.
• Composite frames are beginning to surface in the market and these include foam-filled vinyl frames
with aluminium exterior claddings, wood frames with polyurethane thermal breaks, and foam-filled
fiberglass extrusions with wood interior and aluminium exterior finishes.
WINDOW COATING

26. • Facades are a building’s most visible element.
• Adding plants offers entirely new dimensions of texture, symbolism, and
seasonal dynamism.
• French botanist and green-wall pioneer Patrick Blanc has said, “A simple
wall can become something poetic.”
• Engineered green walls take two forms.
 “GREEN FACADES,” grows climbing vines and ivy on cables or
scaffolds, forming a living screen over a built facade.
 The other green walls—living walls—are dense VERTICAL GARDENS
whose plants seem to burst out of a building’s skin
