Pre-modern methods Craftsmanship. Apprenticeship. Master-bound
trainee for >7 yrs, almost no pay for labour.
Modern methods Machine-based separation between designers
and workers. Technical training. Aesthetic and technical drawings.
Post-Fordist design 1980. Lean design - for customer. Knowledge-
intensive, less hierarchy, less demarcated. Team work, leader-driven.
Knowledge-based planning Public-oriented: advisory, written, debate,
workshop, virtual simulation, gaming.

Lean (flexible) design
• Team starts large and contracts
• Team tightly knit for project time
• Master plan goes in parallel to component design
• Contractors are full member of a team
• All designers have experience in practical construction
• User satisfaction comes in design process
• Team leader is a powerful boss
Mass product (Fordist) design
• Team starts small and later expands
• Team varies in time of the project
• Master plan done first, then component design
• Contractors work to drawings of design team
• Designers lack experience in construction process
• User satisfaction comes from social research
• Team leader is a powerless coordinator

Primary In existing landscapes, from flow of energy, geology, materials, in process of growth and decay. Before man.
Secondary Traits of oldest signs of adaptation of natural landscape to needs of food, shelter, transport, security and comfort.
Tertiary Signs of artistic imagination, aesthetic appreciation of nature. Derive from mythology, decoration, geometry, allegory. Learn for environmental design.
Quaternary Combinations of other patterns that proved successful. E.g. Plant associations, house types, settlement types. Components of outdoor design.

The process of reconnection to the local climate and natural environment, during the planning of a site and design of buildings is called Bioclimatic Design in Architecture and Engineering.
The goal is to design environment and buildings that are:
Energy efficient
Create less pollution
Use sustainable materials
Have better relation to the environment
Provide organic architectural composition

Goals: A. Protection from direct heat radiation B. Avoid both increase in air and mean radiant
temperature Instruments: Orientation of buildings N-S-E-W
• Axis of building parallel to east-west direction Environmental Protection
• Use of landscape and vegetation Window Protection
• movable devices (interior or exterior) such as blinds and louvers.
• Permanent ones- overhangs, fins and awnings • Strategic plantation Special glazing types • Reflecting glass • Absorbing glass • Optical glass

Reduction of infiltration loss • Avoid heat exchange between
exterior and interior. • Avoid humidity entry in the building
Reduction of transmission loss • External surfaces - reduce reflection • Optimal insulation of external shell • Higher thermal inertia - increase the
inward heat flow

Physiological cooling Control air movement velocity Avoid draughts
Apply natural ventilation Improve indoor air quality (eliminate stale air) Achieve body comfort - balance of convection and perspiration
Air cooling Use of evaporating cooling (water basins) Circulating air through underground ducts (raised floor)

Proper landscaping can modify the
climate around your home and reduce
both heat gain in summer and heat loss
in winter.
Properly placed plants reduce
(speedup) wind velocity near the home.

The goal of energy-conserving
landscaping is to regulate energy
flows from the sun and wind.
Windbreaks can save up to 25%
on heating costs.
