- So - what IS embodied energy? Well, there's 2 kinds, initial embodied energy (the energy to build the car) and recurring
embodied energy (the gas to run the car). So taking good care of a car and running it for 13 years at 28 mpg has a lower embodied
energy than trading in a car every 4 years. (Not to mention having to figure out all those new buttons. And don't get me started
on the backup camera - I will hit things or drive off the driveway...) (SIGH - what a Luddite.)
Guidelines for reducing embodied energy:
Design for long life and adaptability, using durable low maintenance materials.
Ensure materials can be easily separated.
Avoid building a bigger house than you need. This will save materials.
Modify or refurbish instead of demolishing or adding.
Ensure materials from demolition of existing buildings, and construction wastes are reused or recycled.
Use locally sourced materials (including materials salvaged on site) to reduce transport.
Select low embodied energy materials (which may include materials with a high recycled content) preferably based on
Avoid wasteful material use.
Specify standard sizes, don’t use energy intensive materials as fillers.
Ensure off-cuts are recycled and avoid redundant structure, etc. Some very energy intensive finishes, such as paints,
often have high wastage levels.
Select materials that can be re-used or recycled easily at the end of their lives using existing recycling systems.
Give preference to materials manufactured using renewable energy sources.
Use efficient building envelope design and fittings to minimize materials (eg. an energy efficient building envelope
can downsize or eliminate the need for heaters and coolers, water-efficient taps allow downsizing of water pipes).
Ask suppliers for information on their products and share this information.
