「香港无冷气夜」是环保触觉一年一度的全港节能活动，此活动透过以少用冷气作为切入点，令市民能够反思人常生活用电模式，减少滥用空调，明白节约能源的重要，从而身体力行减少温室气体排放，加强环保意识。 夏季空调的耗电量佔香港的总用电量约60%，全年平均用在冷气上的用电量约30%。政府在早年已开始推广 25.5℃空调温度，可见善用空调的重要。 过去两年，「香港无冷气夜」得到很多政党、企业、学校及市民支持，获得理想的成效。据本会登记系统的数据，有超过6万个家庭及8间大学宿生参加无冷气夜，估计已减少排放370公吨二氧化碳；加上当晚因颱风关係气温显着转凉，并且有凉风送爽，相信有更多市民当晚没有使用冷气。 今年，我们诚意邀请所有香港市民参与「香港无冷气夜2012」，于2012年9月27日晚上7时至2012年9月28日早上7时关掉冷气机。 下载幼稚园、小学、中学、大学、专上学院、公司、机构、团体参加备忘： http://noaircon2012.blogspot.hk/p/join-us.html “Hong Kong No Air Con Night” is a territory-wide energy saving campaign to promote the wise use of air-conditioning, which targets the general public including Hong Kong households, government officials and university hostels. Green Sense wants to bring out the importance of reducing greenhouse gases and saving energy through this event. It is clearly shown how the public and private collaboration in maintaining the momentum on energy saving. Air-conditioning accounts for around 60% during July to August and around 30% of all electricity end-uses in Hong Kong throughout the year. In the past two years, “Hong Kong No Air Con Night” was a resounding success with the generous support from citizens, the business community, education institutes and political parties. With reference to the pledge collected from the general public, over 60000 households joined and turned off the air conditioning at home and hostels. The campaign saw a reduction in carbon dioxide emission of around 370 tonnes. Under the influence of typhoon, we believed the cooler weather drove more citizens to turn off the air conditioning on that night. We sincerely invite all citizens of Hong Kong to switch off their air-conditioners for 12 hours beginning 7p.m. on 27 September 2012.
