Air-conditioning is important for well-being and even for health. However, in Brazil it consumes a significant amount of energy and has an environmental impact. More efficient air-conditioning respects the environment and reduces the cost of the electricity bill. The Kigali Project aims to help change the energy consumption profile of air conditioners in Brazil by adopting the best international practices. It also encourages the use of refrigerants that have a low potential for global warming.
The time for the peak use of air-conditioning is from noon to mid-afternoon, which is precisely when the peak demand for electricity occurs. This makes it necessary to activate thermal power plants, which are more polluting and more expensive – and makes energy tariffs increase. In addition, the vast majority of the equipment available today in Brazil uses HCFC-22 and HFC-410A refrigerants, which are substances that add significantly to greenhouse gas emissions. For example, the global warming potential of these substances is two thousand times greater than CO2!
The best way to tackle this problem is to increase the energy efficiency of air conditioning equipment and also to replace refrigerants with less potential for global warming – as provided for in the Kigali Amendment.
The models currently available in Brazil are less efficient compared to the standards adopted in most countries and changing this situation is much simpler than it seems. The air conditioning sector has great potential for this change. More efficient air-conditioning respects the environment and, in the medium and long term, also costs less for the consumer – and for you!
MORE EFFICIENCY, LESS WARMING;
MORE EFFICIENCY, LOWER ELECTRICITY BILL
If we were to use 30% more efficient air conditioning than today in Brazil, by 2030 we could save 32 GW of electricity at peak times, avoiding the activation of 52 medium-sized thermal power plants. We would also reduce greenhouse gas emissions from the electricity sector by. 23%, i.e., there will be the equivalent of 16.79 million tons of CO2 that is not released into the atmosphere.
