Cooling Cars with Less Fuel
 
Location and date(s) of workshop:
IEA, Paris: 23-24 October 2006
   
Organiser(s): IEA
   
Contact(s):
   

Background:

The International Energy Agency is exploring ways to improve the efficiency of motor vehicle components, with special emphasis on improvements whose benefits do not appear in conventional fuel economy tests. The goal of this workshop is to identify technologies that will lead to less fuel consumed to cool motor vehicles. Along the way, the workshop will evaluate the causes of present cooling loads and efficiencies in the delivery system. The workshop will seek agreement among experts on procedures to measure the effectiveness of more efficient cooling technologies. The IEA will use results from this (and other) workshops to make recommendations to its member countries on new policies to encourage energy efficiency in transportation.
