Increasing demand for energy
Buildings globally have a major impact on the environment. Today, they consume around 30% of the energy we use and produce 28% of our global CO2 emissions. Based on current trends, this impact is set to intensify in the future as the world’s growing population becomes rapidly more urbanised.
By 2050, there are likely to be 9.7 billion people living on the planet. With around 1.5 million of them moving to urban environments every week, people are more and more likely to live in cities, where they typically spend up to 90 percent of their time indoors. Because everyone wants a comfortable indoor environment, this creates more demand for energy for air conditioning and heating systems. For households, this can be expensive. Heating, cooling, and ventilating our homes is our largest energy expenditure, accounting for up to 16 percent of an average household’s total spending!.
