Introduction
Ecological Design in the context of sustainability refers to
the approach of designing buildings, products, and
systems that work in harmony with the natural
environment.
It emphasizes minimizing environmental impact by
considering ecological principles throughout the design
process, ensuring that resources are used efficiently, and
supporting the long-term health of ecosystems.

Introduction
Its goal is to design solutions that support sustainable
development by reducing resource consumption,
promoting renewable energy, and maintaining
ecological balance.

Introduction
Sustainable architecture combines environmental, economic,
and social factors to create buildings that not only meet present
needs but also safeguard future generations.
By following the principles of
energy efficiency
resource conservation
water management
social responsibility
sustainable architecture helps to create a built environment that
is harmonious with nature and supports the health and well-
being of its inhabitants.

Sustainability princpels
Energy Efficiency: Minimize energy use through passive design, efficient systems, and
renewable energy integration.
Resource Efficiency: Use sustainable, locally sourced, and recyclable materials while reducing
construction waste.
Water Efficiency: Implement water-saving technologies, such as low-flow fixtures and
rainwater harvesting.
Indoor Environmental Quality: Ensure healthy indoor spaces with non-toxic materials, proper
ventilation, and daylight.

Site Selection: Choose sites that minimize environmental impact
and support sustainable community development.
Sustainable Construction: Use eco-friendly building techniques
and systems, like green roofs or energy-efficient HVAC.
Adaptability: Design buildings that can adapt to future needs and
withstand climate changes.
Social & Cultural Sustainability: Ensure buildings are inclusive,
culturally sensitive, and support community well-being.

Low-Carbon Design: Reduce carbon footprints through energy efficiency, low-carbon
materials, and carbon offset strategies.
Lifecycle Thinking: Consider the environmental impact of the building throughout its
lifecycle, from construction to demolition.
Certifications: Aim for green building certifications (e.g., LEED, BREEAM) to meet
sustainability standards.

Sustainable design aims to optimize the use of resources
throughout a product's life cycle. By incorporating
concepts such as :
material efficiency
energy efficiency
water conservation
into the design process, products can be created to achieve
higher performance with lower resource inputs.

Efficient Use of Resources
Conservation of Natural Resources: Reduces dependency
on non-renewable resources by utilizing renewable
materials and energy sources.
Energy Efficiency: Incorporates passive design strategies
like natural ventilation, daylighting, and insulation to
reduce energy consumption.
Water Management: Implements systems such as rainwater
harvesting and wastewater recycling to conserve water.

Conservation of Natural Resources

on Earth.

threshold capacity, coping capacity, recovery capacity, adaptive capacity, and
transformative capacity.
The Five Pillars of Climate Resilience
Climate resilience: is the capacity of interconnected social, economic and
ecological systems to cope with climate hazards and changes, responding or
reorganising in ways that maintain their essential function, identity, and structure.
Resilience is a positive attribute when it maintains capacity for adaptation,
learning, and/or transformation.

it refers to the process of creating livable and
environmentally-friendly urban areas while addressing
economic, social, and environmental challenges.
It aims to achieve a balance between the needs of the
community and the natural environment.

Promotes compact, walkable cities that reduce reliance on fossil-fueled
transport.
Integrates public transportation and green spaces into urban designs to improve
environmental quality.
Incorporates water-sensitive urban design, such as permeable pavements and
natural water management systems.

3. Green Infrastructure
• Incorporates vegetation into urban environments through green roofs, vertical
gardens, and urban forests to enhance air quality, reduce heat islands, and
promote biodiversity.

• Green infrastructure is an approach to water management that protects,
restores, or mimics the natural water cycle.
Green infrastructure is effective, economical, and enhances community safety
and quality of life.
It means planting trees and restoring wetlands, rather than building a costly new
water treatment plant.

4. Decentralized Energy Systems
• Develops renewable energy systems like rooftop solar panels and small-scale
wind turbines to reduce dependence on centralized, polluting energy grids.
it is characterized by locating of energy production facilities closer to the site of
energy consumption. A decentralized energy system allows for more optimal use of
renewable energy as well as combined heat and power, reduces fossil fuel use and
increases eco-efficiency.

5. Sustainable Materials
• Encourages the use of materials that are renewable, locally sourced, and have
a low environmental impact
Sustainable building materials are environmentally responsible products with low
embodied energy, minimal environmental impact, and high durability. These
materials include:
Renewable resources such as sustainably harvested wood, bamboo, and cork,
as well as recycled materials like reclaimed wood, metal, and glass.

1. Passive Design
• Utilizes natural elements like sunlight, wind, and vegetation to create energy-
efficient buildings and systems.
it works in line with the local climate to maintain a comfortable indoor
temperature. The design methodology uses strategies like layout, fabric, and form
to reduce or remove mechanical cooling, heating, ventilation, and lighting.
These strategies take advantage of the climate, site conditions, and materials
to create a building that functions in harmony with the environment and
creates passive design solutions for the buildings.

2. Biomimicry
• Draws inspiration from nature to create innovative solutions, such as energy-
efficient building structures modeled after termite mounds or water filtration
systems inspired by natural ecosystems.
Biomimicry is an interdisciplinary field that involves studying
and emulating nature’s efficient designs, processes, and
ecosystems to create sustainable solutions for human

THE EDGE, AMSTERDAM
The Edge demonstrates that the pursuit of a vibrant and
collaborative work environment can come together successfully with
achieving the highest level of sustainability possible for a building.
It is officially considered to be the world’s most sustainable office building, having been awarded
the highest rating ever recorded by the Building Research Establishment (BRE), the global assessor
of sustainable buildings

THE EDGE, AMSTERDAM
Fine tuning the shape and orientation of the Edge was the initial step in achieving the
exceptional climatic and energy performance of the headquarters.
The arrangement of large floor plates organised around a grand 15-storey north-facing atrium
allows natural daylight to reach the vast majority of the office spaces, while the load-bearing
structure and smaller glazed openings of the south facing facades provide thermal mass and
shade.
The atrium is the lung of the building, ventilating the office space while providing a buffer with
the exterior in a way which reduces energy use in both summer and winter

THE EDGE, AMSTERDAM
As well as its energy-neutral temperature control, energy efficient design and green energy-
generating technology, the Edge captures rainwater and stores it underground for use flushing
toilets and watering plants in the interior and exterior gardens.
