(29 Sep 2017) Hong Kong No Air Con Night 2017

Hong Kong No Air Con Night 2017

PolyU has pledged to support the Hong Kong No Air Con Night launched by Green Sense from 7 p.m., 29 September to 7 a.m., 30 September 2017 to bring out the importance in reducing greenhouse gases and saving energy through the wise use of air conditioning.

Why are we doing this?

Since 2010, PolyU has been a trustful partner to this meaningful event and we believe we have the right cause. It is not difficult to understand air con cooling translates into great electricity consumption and brings impacts to our Earth. Yet we must not forget that there are good and clever practices to stay cool and use energy more wisely. Together we can reduce our reliance on air conditioning and help to conserve energy.

How can you help?

I would like to take this opportunity to seek your support in the following respects for the campaign. Please help to:

  • Switch off the air conditioners for 12 hours from 7 p.m., 29 September to 7 a.m., 30 September at your home or student hostel and turn off unnecessary ones in your office;
  • Share the message with your friends, colleagues and family; and
  • Pledge to support the event by filling in the Green Sense’s online pledge form at
