Factors affecting energy efficiency
• Use of Raw Materials – Embodied Energy• Location/Transport • Processes• Waste
![Page 6: A Roofer’s Guide to Sustainability](https://reader038.vdocuments.us/reader038/viewer/2022102818/56812b77550346895d8f9629/html5/thumbnails/6.jpg)
Embodied Energy
• Embodied Energy is the total of all the energy required to produce goods or services, considered as if that energy was incorporated or 'embodied' in the product itself.

Are you on Standby?
• Leaving appliances on standby can account for between 9% and 16% of your electricity usage.
• Study by Energy Saving Trust and DEFRA
• Are you really happy that this amount of your energy bill is wasted?

Energy Saving tips
• Keep the Heat In – Close doors and windows• Use energy saving light bulbs• Insulate – cut out the draughts• Only heat enough water for immediate use
