Energy efficiency considerations

Energy efficiency refers to using less energy to perform the same task, reducing energy waste. This is critical in sustainable design.
Products should be designed to consume minimal energy in their operation. For example, using LED lights instead of traditional bulbs.
Energy consumed during production also needs consideration. Techniques such as lean manufacturing may reduce energy usage in production processes.
Stand-by power consumption is another factor. Devices that consume less power while not in active use are more energy-efficient.
Consider energy-efficient transportation. Design smaller, lighter products to reduce fuel used during shipping.

Understand a product’s energy lifecycle from creation to disposal. Identify stages where energy consumption can be minimised.
Including repair and maintenance in design considerations may extend product life, reducing energy consumed in the production of replacements.
Designs that enable disassembly at the end of life can facilitate reuse or recycling, saving the energy required to produce new products.
Remember to consider the energy used in materials’ extraction and processing. Using recycled or reclaimed materials can help reduce this.

Choose materials that have low embodied energy, i.e., energy used in their creation, transportation, and disposal.
Use insulating materials in product design to reduce energy waste in heating or cooling.
Opt for renewable energy sources where possible. For instance, design products to be solar-powered.

Be aware of energy efficiency regulations. Many countries enforce such guidelines to promote sustainable practices.
Look for energy efficiency certifications. Products and systems might be rated with these to indicate their energy consumption levels. Examples include Energy Star or the EU Energy Label.
