⭐️ ⭐️

*** WHAT'S COVERED ***
1. Methods for reducing unwanted heat transfers in buildings.
* Reducing heat transfer by conduction using materials with low thermal conductivity.
* How cavity walls and double glazing work to reduce heat loss by conduction and convection.
* Preventing convection by sealing gaps and using features like curtains.
2. Techniques for reducing energy loss from friction.
* Using lubrication to minimise friction between moving surfaces.
* The principle of streamlining to reduce air resistance and improve efficiency.
