Heating, Ventilation & Air Conditioning (HVAC) forms an integral part in many developments and advancements in the everyday world around us.
The demand for air conditioning is ever increasing. According to The New York Times, in May 2018, 90 percent of American households have some sort of air conditioning system. It is almost more common to have an air conditioner than a dishwasher, garage or dining room. However, in countries that experience warmer climates, such as Africa, Asia and the Middle East where approximately 2.8 billion people live, only 8 percent of that population own an air conditioner.
The United Kingdom, a country which averages a temperature of just below 20 degrees Celsius, is said that only 0.5 percent of houses and apartments have an air conditioner – according to a 2008 Mintel report. The United Kingdom is rather a country of radiators, as heating is in a higher demand than cooling. By 2017 a total of 95 percent of UK homes owned a central heating system.
Air conditioning, in particular, has always been a concern due to the high energy demands. In July 2013 almost 15 percent of America’s energy usage was due to air conditioning. This number has since dropped due to new industry innovations.
The industry has developed new, more efficient, methods of heating and cooling which positively impact the environment. Developers are now encouraged to follow guidelines on energy usage and adopt the newer, greener, HVAC systems.
The World Green Building Council are just one of the organizations dedicated to ensuring the transformation of the built environment. The Green Building Council of South Africa had reported that 680 Million kgCO2 and 570 Million kWh will be saved per annum – this follows the news that "Africa has reached 400 green building certifications through the GBCSA in September 2018".
This is just one example to show how the world, and the HVAC industry, is drastically changing. The need for air conditioning and heating is growing, and luckily the innovative technology is there to follow it and support not only the demand of the population, but also the demand of the environment.
