Contents include:


  • The Science of Cold Draughts.

An article aiming to give an answer to the question: “How do you ensure a steady flow of fresh air into a room in winter without the ensuing cold draught?” and thus addressing controlled mixing as a critical feature of the ventilation strategy.


  • What do we know about infiltration and exfiltration? 1 - An introduction.

An introduction to how air enters and leaves a building.


  • A camel’s nose.

An article looking at the dromedary camel’s breathing cycle as an inspiration to design solutions to limit evaporation from water storage ponds, design more efficient irrigation systems and learn how to best minimise loss and recapture water used in industrial processes.
