We are pleased to inform you that The Education University of Hong Kong (EdUHK) has joined the Energy Saving Charter, organised by the Environmental and Ecological Bureau (EEB) and the Electrical and Mechanical Services Department (EMSD), again this year. At the invitation of EMSD, we attended the Launching Ceremony held at Plaza Hollywood on 23 June 2026.

To achieve energy saving through daily action, we would like to invite everyone to take part in simple energy-saving practices in the offices, classrooms and study/working spaces.

1. Set appropriate indoor air temperature

• Please maintain indoor air temperature at 24 to 26°C during summer months from June to September.
• Keep windows and doors closed when air-conditioning is running.
• Keep doors between air-conditioned and non-air-conditioned areas closed to reduce air leakage.
• Switch off the air conditioning when the area is unoccupied.
• Dress lightly to stay comfortable with less AC.
• Use lower fan speed settings as the normal setting (use higher fan speed first only if needed, rather than lowering the temperature immediately).

2.  Switch off appliances and systems when not in use

• Switch off lights when the area is unoccupied.
• If you leave your office/classroom, please turn off the equipment you are responsible for (e.g. computer, screen, lights).
• Avoid leaving chargers and adapters on standby.
• Unplug chargers/adapters when not in use.
• Switch off your computer screen when you leave for a while—using screen saver is not as energy-saving.
• Please support a “last-man-out” check and switch off the followings:
  • Lights
  • Air conditioning
  • Office equipment

2. Use energy-efficient choices when applicable

• When you need to replace equipment, please choose energy-efficient models, such as those with Grade 1 energy labels (as far as practicable).

Saving energy doesn’t require big changes—small actions by each of us make a real difference. Let’s do it together!

香港教育大學再次參與由環境及生態局及機電工程署主辦之由環境及生態局（EEB）及機電工程署（EMSD）主辦之節能約章計劃，更獲機電工程署邀請，參加於2026年6月23日於荷里活廣場舉行之啟動禮。

為達致透過日常行動提升能源效益，我們誠邀大家在辦公室、課室及學習／工作空間參與並落實簡單易行的節能措施。

1. 設定合適室內空氣溫度

• 請於6月至9月夏季期間，將室內空氣溫度維持在24°C至26°C。
• 冷氣運行時，請保持窗戶及門關上。
• 為減少冷氣外洩，請保持空調範圍與非空調範圍之間的門關閉。
• 如空間無人使用，請關掉空調。
• 以適當穿著維持舒適感，減少冷氣使用。
• 冷氣風量方面，請以較低風速作為常用設定；如有需要，才先使用較高風速，不建議急即把溫度大幅調低。

2. 在不用時關掉電器及系統

• 如空間無人使用，請關掉燈光。
• 若離開辦公室／課室，請關掉用電設備（例如：電腦、屏幕、燈光）。
• 請避免讓充電器及轉接器長時間處於待機狀態。
• 不用時，請拔除充電器／轉接器。
• 暫時離開座位時，請關掉電腦屏幕 — 使用螢幕保護程式並非最省電。
• 請配合「最後一位離開者」檢查機制，於離開前關掉以下設備:
  • 燈光
  • 空調
  • 辦公室設備

3. 盡量選用具能源效益的產品

• 當需要更換設備時，請盡量選用具能源效益的型號，例如具1級能源標籤的產品。

節能不需要大幅改變，只要大家都付出一點點行動，便能帶來實質成效。讓我們一起參與節能！
