1.2 How the critical evaluation of new and emerging technologies informs design decisions; considering contemporary and potential future scenarios from different perspectives, such as ethics and the environment
How to critically evaluate new and emerging technologies that inform design decisions: budget constraints, timescale, who the product is for, the materials used, manufacturing capabilities
How critical evaluations can be used to inform design decisions, including the consideration of contemporary and potential future scenarios:
natural disasters, medical advances, travel, global warming, communication.
Ethical perspectives when evaluating new and emerging technologies:
where it was made, who was it made by, who will it benefit, fair trade products.
use of materials, carbon footprint, energy usage and consumption during manufacture and transportation, life cycle analysis (LCA).
1.3 How energy is created
Environmental perspectives when evaluating new and emerging technologies:
sources, generation, and storage of energy:
Coal, gas, oil, Nuclear, Wind, solar, tidal, hydro-electrical, biomass
Powering systems batteries and cells, solar cells, mains electricity, wind power

Aesthetic factors: form, colour, texture. Environmental factors: sustainability, genetic engineering, seasoning, upcycling.
Availability factors: use of stock materials, use of specialist materials, environmental impact of hurricanes, storms and disease.
Cost factors: quality of material, manufacturing processes necessary, treatments: fire proofing, tanilized.
Social factors: use for different social groups, trends/fashion, popularity.
Cultural and ethical factors: avoiding offence, suitability for intended market c the consumer society, the effects of mass production, built-in product obsolescence.
Forces and stresses: compression, tension, shear, natural forces within the timber as it grows, pre-stressed construction beams.
