This document outlines the contents and topics to be covered in a presentation on biomimetic architecture. The contents include an introduction to biomimicry, backgrounds on how it began, approaches to biomimicry including design to biology and biology to design. It also discusses principles of biomimicry such as nature running on sunlight and recycling everything. Steps to adopt biomimicry are provided, which include biologizing the question and developing designs inspired by nature. Case studies, analysis, applications and conclusions will also be part of the presentation.

3. WHAT IS BIOMIMETICS?
Biomimetics is the term used to describe the
substances, equipment, mechanism and systems by
which humans imitate natural systems and designs.

INTRODUCTION B070225AR

4. • Biomimicry originates from two Greek words
Bios = Life
Mimesis= imitate
• Biomimicry operates on the principle that in its 3.8
billion year history, nature has already found
solutions to many problems we are trying to solve.
• Biomimicry is multi-disciplinary subject involving
wide diversity of other domains like architecture,
electronics, medicines, biology, chemistry,
mathematics etc.

8. HOW DID IT BEGIN?
• American biophysicist and
polymath.
• Coined the term Biomimetics in
1950’s.
• Developed Schmitt trigger by
studying the nerves in squid.
• Attempted to engineer a device
that replicated the system of
nerve propagation.

9. HOW DID IT BEGIN?
• American writer and scientific observer
from Montana.
• Wrote the book “Biomimicry: Innovation
Inspired by Nature” in 1997
• The books gives an insight on how
significant biomimicry is in shaping the
future.
• In 1998 she co-founded the Biomimicry
Guild which helps inform , inspire and
empower the bridging of nature’s wisdom Janine M. Benyus (b 1958)
with human knowledge.

14. PRINCIPLES OF BIOMIMICRY
• Nature runs on sunlight.
• Nature uses only the energy it needs.
• Nature fits form to function.
• Nature recycles everything.
• Nature rewards cooperation.
• Nature banks on diversity.
• Nature demands local expertise.
• Nature curbs excesses from within.
• Nature taps the power of limits

"Sustainable development is development that
meets the needs of the present without
compromising the ability of future generations to
meet their own needs.”

27. SUSTAINABLE DESIGN FRAMEWORK
1. SITE & CLIMATE ANALYSIS: analysing site, orientation, exposure, climate,
topographical factors, local constraints and natural resources
2. FLEXIBLE STRUCTURAL SYSTEMS: investigating structural characters,
permanence/temporariness, integration with building components, etc
3. RENEWABLE BUILDING MATERIALS: analysing efficiency of a material or a
product, size, standardization, structural adequacy, complexity,
appropriateness, cost, labour involved, plantation origin, method of growth,
embodied energy, recycled and reused content, toxicity, etc.
4. BUILDING ENVELOPE SYSTEMS: control of energy flows that enter (or leave)
an enclosed volume, including consideration of orientation, seasonal
variations, surrounding environment, function, and typology.

28. 5. MODULAR BUILDING SYSTEMS: construction and assembling methods to
facilitate substitution, repair, maintenance, diversified lifetime, etc.
6. RENEWABLE & NON-CONVENTIONAL ENERGY SYSTEMS: integrating sources
of energy that do not reduce or exhaust their point of origin;
7. INNOVATIVE HVAC SYSTEMS: implementing strategies to provide thermo-
hygrometric and air quality comfort, exploiting mechanically regulated, hybrid,
or, preferably, totally passive techniques;
8. WATER COLLECTION & STORAGE SYSTEMS: adopting methods, system and
strategies to collect, store, distribute, use, recycle and re-use water.

• Multi-Water Reuse (MWR) sewer mining plant
• Sprinkler water reclaim and rainwater collection
Waste
• building waste during construction was recycled
(87%)
• recycling carried through within building after
operations  waste separation

To echo, listen, steward and immerse in nature
Biomimicry presents itself as a basis, a foundation of a new research methodology instead of
mere serendipity. Biomimicry has to be approached in a multi-disciplinary order of thought in
order to understand the principles of nature to achieve a holistic design solution.
