Enter a greener limelight

The Australian: "The Malthouse has just launched its Greenlight Project, a combination of redesign, reduction in waste and a carbon offset scheme. An audit by RMIT students in the school of global studies, social science and planning found that the theatre generated 600 tonnes of carbon annually, equivalent to 2200 medium-sized cars. 'Sixty per cent of that is from theatre lights, they're the killer, and air-conditioning is whopping too,' Kantor says. The convention is to keep the theatre at a constant 21C: he would like to see a greater audience tolerance for a wider band of temperature, between 18C and 25c. Lights generate a lot of heat. Lower wattage Source 4 lanterns are two to three times more efficient, and Kantor is waiting on a source of funding for them."
