Saving Our Environment
At Queens, we are very environmental conscious and we support recycling and saving electricity and water. We had made some progress and wish to improve on it. If members have any recommendation, please feel free to inform the condo manager or any of the council members. Thank you.
At Queens, we are very concerned about energy wastage and we support Earth Hour. During Earth Hour every year, since 28 Mar 2009, we switched off all the perimeter lightings and the lights that lit up the dome at the clubhouse from 8:30pm and we even keep them switched off throughout the whole night. We wondered if you were even aware of that.
Recycling bins were introduced to encourage recycling. Currently bins for plastic and glass bottles, metal cans and papers were placed at every block. Those who are environment conscious will welcome this convenience. It was also encouraging to see many who had previously thrown such recyclables down the rubbish chutes, had now brought their recyclables down to the recycle bins. We note that most people will like to recycle and would readily do so if it is not too inconvenient.
Energy Efficient LED Lightings
During an energy saving exercise in Nov 2011, all the lightings at the car park were changed to LED tubes with a lower wattage to save energy. The stairwells which were formerly lighted with 2 pieces of 22 Watts florescent tubes were replaced with 10W LED tubes. Similarly, all the corridor lights were replaced with lower wattage LED lights. The 22W spot lights shinning up the plants were replaced with 9W LED spot lights. The perimeter lightings were replace with lower wattage LED and the number of lights were reduced by half.
Variable Speed Drive Motors
We engaged a consultant to implement energy saving measures using variable speed drive motors so that energy can be saved by running the motors at lower speed when the load is light. These were implemented on all water pumps and aircon compressors since Nov 2011. The energy saved together with LED lightings is about $5000 per month. We should be able to save $200,000 in 4 years time.
To conserve energy, the waterfalls and water features were shut down after 9:30pm. The swimming pool lights were switched off after 10pm.
Some of the lightings along pathways were switched off after 10pm. It is still sufficiently bright for safety and security.
Each light socket was previously fitted with 2 energy saving compact flourescent lightings. One lighting in each socket was removed and it was still sufficiently bright.
Multi-storey Car Park
We had switched many of the lights in the multi-storey car park especially the small lights on each column. Formerly, there were 2 flourescent tubes in ceiling lighting casing and one tube is either removed or disabled. That cut down half of the energy consumed. The timer had also been adjusted and monitored closely. Now, these tubes were replaced with a single LED tube and without a translucent casing, the light output is not reduced.
Previously, the spot lights used were incandescent bulbs of 120 watts. These were replaced with flourescent spot lights of 23 watts. In early April 2009, we disabled every alternate spot light, thus further saving on electricity. Since Nov 2011, these were replaced with 9W LED spot lights.
We had set the timer to switch off some of the spot lights and other lightings after 10pm. This not only save energy when we were all sleeping, it is also less glaring for those on the lower floors trying to sleep after 10pm. These were replaced with LED lights.
The guards are constantly reminded to switch off the air-con immediately after each court booking so as not to leave the air-con running to cool an empty room.
Common Shower Rooms
The water heater was shut down after 9:30pm to conserve energy. The remaining water in the tank is more than sufficient to cater to swimmers until 10pm. The energy saved would otherwise had gone to waste to re-heat the water in the tank during the late nights even when there were no user.
The gardeners were informed to water the plant with just sufficient water as too much water is not good for the plant as it can damage the roots. Also, excess water will just sink into the ground and wasted.
The cleaners were told not to waste water by leaving the taps running. They are also constantly reminded not to use the fire hose for cleaning. Water hoses were fitted with a hand operated nozzle.
