What is Bioclimatic design
Making use of renewable energy and local bio-climatic / environmental sources (Air/wind, sun, daylight,
vegetation, water soil, rock/stone, bio-based materials)
→ Reduce need for non-renewable energy
Designing to 'live lightly on earth'
More human powered and less resource intensive buildings & lifestyle
→ quality and resources can remain for generations to come
BCD in architectural discours
1950 - 60
Climate and Thermal comfort
Victor & Aladar Olgyay reintroduce the concerns of biology, meteorology and engineering into architecture
Nature
Ian Mcharg : Human cooperation & biological partnership in design
Relationship between built environment & nature reinstated to their full potential without being destructive
to each other
Energy
Buckminster Fuller's Dymaxion principle: Maximal gain for minimal energy input
Vernacular
The verancular and the appropriate tech - Hassan Fahty
Tropical Architecture
J.B. Drew and E. Maxwell Fry
Bio-mimcry and Design
Copying designs for structures from shapes in nature
1970s - Performance / energy engineering in architecture
High tech aesthetics, expressive potential of structure
Bv: Centre pompidou
Bioclimatic Design Pagina 1
,1990s - Performance / energy engineering in architecture
Materials, embodied energy, formal incorporation of performance / energy in architecture
Cultural specificity & polyvalent performance
2000s - Integrated design
Energy, heating, lighting, materials, construction embedded in place
Energy efficient design, polyvalent performance
Sustainability as intrinsic value in architecture
Bioclimatic, carbon neutral cities of the future
Defining & conceptualizing Bioclimatic Design
A responsive (re)configuration of the relationship between
Climatic or bio-ecological conditions of a specific context
The site
And the buildings
To provide visual, thermal & acoustic comfort
& create a symbiotic, sustainable energy efficient and embedded in place environment
Bioclimatic Design Pagina 2
,Important to understand
Climate
Sun & solar geometry, air, temperature, wind, humidity
Site bio-configurations
Topography, orientation, soil, water, vegetation
Material properties
3Rs, embodied energy
Passive systems & design strategies
Energy, Heat & Air flow, shading, ventatilation & light
-> Minimal resource and energy use
Energy Balance and microclimate impacts
Cities and roads graduatly replace natural landscape
-> Alters the bio-climatic conditions of the region
-> Changes the relationship between
Incoming solar radiation
Outgoing terrestrial radiation within watershed areas
-> Alters local energy balances through changes in
Albedos of surfaces
% of incoming solar radiation reflected by a surface
Urbanization decreaces the overall albedo by apx 10%
Specific heat capacities & Thermal conductivities of surfaces
The ratio of sensible heat to latent heat flowing from surface into atmosphere
Sensible heat: Heat energy felt & measured with a thermometer
Latent Heat: Heat energy stored in water vapor
Cannot be felt or measured
Is not available for sensible heating
It is a cooling process
Climate Change & Sea level Rise
LECZ or Low Elevation Coastal Zone (<10m asl)
Bioclimatic Design Pagina 3
, LECZ or Low Elevation Coastal Zone (<10m asl)
Covers 2% of the world's land area
Contains 10% of total population
Contains 13% of Urban population
Enormous exposure of population and assets makes them front line for action
They are of Financial, physical, environmental and socio-cultural importance
Consequences of climate change
Climate Change: Adaptation measures
Managing the unavoidable: To limit impact of CC both locally & globally
Water
Flood control
Protection against sea level rise
Water scarcity in dry areas
Weather
Typhoons, storms
Heat waves, UHI
Fires close to cities
Others
Migration control
Improved agricultural productivity
Support to bio-diversity
Mobility Flows
Water ways
Air Ways
Land Ways
Human mobility & Tourism
