9. Natural ventilation

14 January, 2009

55 Monodraught Windcatchers on the roof of this building on Kennington Park Business Centre in London provide natural ventilation, with cooling, for offices on the third floor.

Taking energy-using plant out of a building is certainly one way to cut back carbon emissions. A well-planned natural-ventilation project will allow a building owner to do just this. Natural ventilation uses the forces of wind and buoyancy to drive fresh air into buildings. It is arguably more an approach than a technology, but products can be designed to help the process carry out tasks such as filtering pollutants that may be caught up in the air. With legislation increasingly favouring natural, low-carbon solutions, could natural ventilation be the H&V technology to claim the crown of carbon champion?

More refrigerant bans possible, says government

The government could tighten up the rules that restrict the use of global warming refrigerant gases including speeding up phase-out programmes and introducing new bans, according to a spokesman from the Department for Environment, Food and Rural Affairs (DEFRA).
