Energy Profile

Post by GranSport » Sat, 31 May 2008 5:00 pm

hello, wonder how this compares to your consumption, just received my
last utilities bill...

March, 1226 kWh @ 0.2399 / SGD 292.77
April, 1320 kWh @ 0.2262 / SGD 298.58
May, 1634 kWh @ 0.2388 / SGD 390.20

Profile:
landed property, 3,600 sqft, 9 aircons, 2 Adults, 2 kids

usage:
aircon, we avoid the usage, we only use 1 aircon for roughly 12 hours
a day, as for the rest, we use two simple fan's (70 W each). as for
the rest, fridge (24h), wash/tumble (1 load per day), TV 46 LCD (4 hours
a day), PC, 1 notebook running constantly....

so, what do you think? something wrong?

cheers

We have only 1500 sq ft, and one child, our energy bill is over 100 every month, but under 150, and we use the aircon in the bedrooms with fans, on a timer in both bedrooms, for 6 hrs total, not every night. if possible we wouldn't use aircon.

By looking at the size of your property, and bill, I would believe it is mostly lights that are left on, by the kids.

You may benefit by reducing the aircon, with the timer., to 3 hours per bedroom each night or less, you only need it, to sleep, once asleep, you should be okay with a fan.

Never have it blowing towards your face if you can avoid it due to the micro dust particles and germs you cannot see. Otherwise you will feel stuffy nosed when waking up. Clean aircon filter every month too helps breathe better not the pocket!

Run aircon 12hrs a day is a luxury most cannot afford, for that size of property and 12 hrs aircon, i would have to say your bills are normal. I would suggest you try to use aircon, just for sleep 3 or 4 hrs, each bedroom, you may half the bill.

if you got halogen lights, they are very power hungry, some at 50watt EACH. so with each room having 4 or more halogen lights, they all add up the watts.

air-cond defo is the one taking the most wattage. if you can set your washing machine to a lower temperature, then that would save the wattage.

turn off all other stuff that has standby on it.

Make sure you are running energy efficient devices and machines:
  • Replace your "power bricks" (the ac to dc converter that usually has an abysmal efficiency of 50% or so) with more efficient power bricks. you can buy them on the open market.

    for Air conditioners go for those certified with National Environment Agency's "4 ticks"

    Water heaters are another major energy sucker - make sure they are turned on only some time before use and are turned off after use. (install a solar water heater if feasible)

    if feasible, install solar panels to augment electricity from SP Power.

    make sure the windows are properly shaded and the house has proper insulation.
there are just some tips - im sure google can tell you many many more :)

previous post was right: it's the lights.

have your garden/gate lights got timers? are your porch lights (and those lights that run around the house) energy saving ones?

it's time to change! : )

also turn your water heaters off during the day if they all comes with a switch.

if you're lucky, sometimes the pipes get heated up pretty good out in the yard and produce luke-warm water for a while!

i just hope it's not a rogue appliance.

Decreasing the number of children you have is also a good way of reducing your energy bills. JK, but on a serious note those $$ look about right considering your floorspace and family size. Consider portable fans - there are some really good, quiet ones here that have night timers as well. Use abt 50% less energy than an aircon.

bought 2 fans and a dehumifier (370 watt), switched off the
aircon in the masterbedroom and exchanged outdoor bulps to
'hightech only 6 watt pieces..' and bling bling, reduced my
powerbill by 20% MoM.

will try to achieve around SGD 250/month

Just note that electricity costs are now about 23 cents per kilowatt hour.

Your usage is reasonable, low even.

Hey Gransport - on the back of our SP bill we have 3 graphs which show our electricity, gas, and water usage and this includes the national average [for our type of dwelling]. Not sure if that's of any use. If you want our details happy to provide them.

Cheers, C & P

C&P, if I only could pay more attention.... thank you for the hint, the graph is telling me that i'm way above the national average, would
assume roughly 20 %, on the other hand, with regards to the water
usage, i'm way below (national average 29.3 m3, my consumption
is roughly 10 m3 per month)......


thank u again,
GranSport

also take note that the reading of the meters is bi-monthly only (see the asterisk), so you might not see your overall savings immediately

Hey Jens - true - but ours has a full 4 months on it and comparing it to the other months it's statistically OK - ish!

Good point, though Jens...thanks for picking me up on that!

tx, good point indeed - the weighted average is still way above the
national consumption. don't think i can manage it much lower, if i
compare this to back 'home' in europe i spend about the same p.a. (if i
take heating into account), funny enough 'there' i did not bother the
'amount' just looked OK, here i do - having a monthly 400 SGD bill
for power is; well... hard to accept (... ;-) don't like to pay for things
which you can't touch ;-) ) .... so, have to adopt and accept....... tx guys!
