IB Design Technology Topic C2.1.2: Datchefski’s Principles Notes

Datchefski's Five Principles of Sustainable Design

1. Five principles that facilitate a holistic approach to sustainable design:
   1. Cyclic
   2. Solar
   3. Safe
   4. Efficient
   5. Social
2. They focus on the full environmental, social, and functional impact of a product.

Cyclic

1. Uses recyclable or compostable materials
2. Designed for reuse, repair, or remanufacture
3. Avoids landfill waste
4. Encourages closed-loop systems

Solar

1. Manufactured using renewable energy (e.g. solar, wind)
2. Operates using low or no fossil fuels
3. May include solar charging or energy-harvesting technology

Safe

1. Avoids hazardous materials or chemicals
2. Ensures safe handling throughout lifecycle
3. Uses non-polluting processes
4. Complies with health and safety standards

Efficient

1. Lightweight or material-efficient design
2. Minimises energy during use (e.g. energy-saving electronics)
3. Reduces production waste and emissions

Social

1. Ensures safe, fair labour practices
2. Promotes local production or sourcing
3. May support community development

Applying Datchefski's Principles

When analyzing a product for sustainability, consider how it aligns with each of Datchefski's principles:

1. Cyclic: Are the materials recyclable or biodegradable?

1. Solar: Does the product use renewable energy in its production or operation?
2. Safe: Are there any toxic materials or harmful byproducts?
3. Efficient: How does the product minimise resource and energy use?
4. Social: Does the product support ethical labor practices and community well-being?
