Hong Kong No Air Con Night is a territory-wide energy saving event to promote the wise use of air conditioning, starting from 2010, in order to lower the emission of greenhouse gases. We sincerely invite everyone in Hong Kong to switch off their air conditioners for one night, suggested from 7pm to 7am the next morning.
Wall-like high rises block the sunlight from reaching indoors and weaken air ventilation and as such, we usually feel hot and humid on streets. In contrast, it appears that all our needs are satisfied in shopping malls while it sounds so difficult to find a tranquil and refreshing park for relaxation. So, what is missing in our lives – material or quality? The city designs our way of life. Yet, we have to contemplate our impact to the environment.
Many shops try to attract costomers by having their signboards and spotlights on even during day time of sunny days. In Hong Kong, around 20% electricity is consumed for lighting. Much of it is believed to be unnecessary and excessive. With wasteful electricity consumption, it is impossible for us to have clean air and clear sky, even in heaven.
Air-conditioners consume lots of energy and it accounts for about 60% of the total energy consumption in Hong Kong during July and August, or about 30-40% for the whole year. Nevertheless, there are many places in Hong Kong where the indoor temperatures are as low as 18-22 oC while the outdoor temperature is over 30 oC. Both our health and environment are adversely affected with such sigificant temperature difference of over 10 oC.
