The lifts run 24hours, and they’re probably one of the most hardworking mechanical/electrical unit in Singapore. If that’s not bad enough, they are still being abused everyday despite fake CCTV threats/fine notices being pasted on the walls. Well, occasionally beloved passengers quench their thirst by feeding them pee or curry on the floor. Some try to push it by lighting one up in the lifts.
One thing which you would/would not have observed is that the lifts have been programmed to move to a ‘sweet-spot’ position, usually on the higher level. Usually after 9 or 10pm ( Im not sure ), it’ll automatically move to level 7 ( my block has 11 accessible floors ), regardless of where the last passenger jumped off. They must have did some kind of research ( I hope ), garnered some kind of data, to prove that at night there’re a lot of residents who’re coming home, and they ride up, and then the lift’s optimal position, is at level 7. Which makes it easier ( less energy, duh ) to slide down, and pick the next passenger up to higher levels, and then it’ll go back to level 7.
Currently there’s only two settings ( I believe ), 7pm – 7am, and 7am – 7pm. And during the day, they just turn off the above algorithm.
This phenomenon is obviously the clever implementation of the electrical engineers, to try to conserve.
Well, in 30 seconds, I just thought of a few solutions which hopefully can save more electricity.
Now. Let’s look at the bigger picture, and you’ll see how my idea works. There’re a fixed amount of residents for every block. There are 3 lift services servicing these 600 or so residents ( 11 floors x 10 homes x 4, plus minus 3 per home ) . They all have a pattern which can be learnt, and if we can collect the data of their lifts usage, we would have a higher ability to predict the lifts’ location. Weekends are bitchier, if you observed enough, relatives turn up on weird timings, but everyday, you get almost a predictable cycle. Well, if everyday is different, could we do a weekly cycle? That means everyday, we know that half the people use the lifts to go down, so almost all the trips upwards go to waste. How do we tackle this?
Could we install some kinda device to kinetically charges the lifts batteries when they slide down? We’re talking about installing the same kinda batteries for cars, onto lifts. Greenlifts.
In the mornings, everybody is rushing to work. But what about freaking lift pooling ? Wait for a full load before it goes down ? This is the solution to compensate the empty upward rides. Since the mornings, the lifts are just working NONSTOP. Mornings meaning 7-8am +-1 hour
Well, a lot of you might be thinking, you freaking purchased your home, and now you need to lift pool ? What? Think about it. You buy things from the supermarket, and it has been so common for them to give out plastic bags to you. But you accept it anyway. Im sure you can wait for 1 or 2 minutes before taking the lift. We don’t turn on the aircons even though it’s freaking warm. Obviously this go green thingy takes out some of our comfort. But it’s worth it ( I hope )
And for the nights, they should just shut down one of the lifts, and just use the other two. Or shut down the other two.
And use only one. And why are the lights are not MOTION ACTIVATED YET !? The sensor costs about $1 +- 0.35 and prolly almost brainless to be installed. It’s just flip flop switches. Come on. Why bother installing them at high end condos only, when it’s all the other HDB’s that are sucking up the electricity, right?
I’m not going to tell you why you should reuse reduce recycle. Go figure.
P Before printing, please think about the environment.
