Towards LED lamps for school lightings

-
Contributed by ANG JOO LIAK

 Current situation:
There are many dim yellowish lights along the school corridors as well as indoors (e.g. Conference Rooms and LTs). These are incandescent bulbs or some compact fluorescent lights (CFL).

 Improvement:
Research and development has shown that LED lamps last longer, and much more energy efficient than incandescent filament bulbs and CFL. The energy cost savings and better lighting for safety (outdoor) and staff & students' eyesight (indoors) are important reasons to switch all lighting to LEDs as soon as possible. Reference: 4 August 2018 The Straits Times, B9, article "The future's bright". - each LED annual energy cost = $3.11, saves 75% over incandescent lamp (say $10). Suppose 300 lamps changed.

Contributed by Dilys Tan Puay Miow,  Junita Wong, Luis, Fan Kaideng, Yao Ling Yun What was the current need/gap that you were addressing? Presented the idea of giving vouchers to all staff for their birthdays instead of a physical gift. The existing model of giving physical gifts contribute to wastage & environmental unfriendliness, should gifts not be to staff's liking. Vouchers allow staff flexibility to buy whatever they require. Staff can also opt to donate vouchers to charity in the school's name which contribute to NYGH CSR efforts. How had it been experimented and enacted? Had a meeting with SWC chairman, SWC advisor & SH community Development to discuss the idea. SWC chairman brought the idea to Bursar. And she discussed with management team and was agreed and approved on 12/7/2023. It was implemented in 2024. What was the positive impact? 1) reduced wastage of gifts 2) flexibility for staff to buy what they need.

Contributed by CHEN HSUAN CHIEH, SAM CHOON JUEN, ALEX TEO What was the current need/gap that you were addressing? Before 2023, the internal advanced Chinese oral examinations for Secondary Three and Secondary Four were conducted over three afternoons, from 1:30 pm to 5:00 pm. This approach posed several issues: Conducting exams over three afternoons disrupted afternoon classes. 1. Staffing arrangements were challenging, as a significant number of teachers were needed to serve as assistant oral examiners (AOE). The availability of AOE teachers did not always align with the designated oral examination times as they have other lessons in the afternoon, resulting in difficulties in staffing arrangements. 2. The time spent by AOE in performing their duties was considered part of the year-end exam invigilation time. Deducting their time during the scheduling of year-end exam invigilation not only made the timetable creation process tedious but also contributed to a shortage of invigilators f
