integration should start where there's no prejudice, at the root, at a young age, at the primary school. or even younger at the preschool.

yet the plan to scrap all the different vernacular schools in malaysia are heavily opposed and could not be done previously. we're still continuing the segregation, and indirectly supporting it by avoiding the school integration.

Their electric bill is ~rm1000 for a family of 4 but then they never complaint as their average income is rm30000.

seriously - if you are so sure about being cheated go ahead and file a claim. and this has *nothing* to do with government. the court will accept and expert witness with credentials. i encourage you to sue tnb if you think they cheat you. get evidence, confront them, demand compensation and rectification and if they dont budge, sue them - easiest is in small claims trial which limits your claim to RM 5000 but you can add side demands (working meter, affirmation of a no future overcharges etc. etc.). the problem i see is that ppl like to complain but they dont act on it. if i were you, i'd be breathing down tnb's neck already. no need to be scared of glc-companies - i personally took three to court before results: two wins, one settlement (which essentially was a win too). and mind you this involved a major local government controlled bank. no need to be afraid to use the tools at hand. but honestly: under normal cicrumstances their meters are spot on - i have my own data to compare to (old/new meter). so i dont see a case but then i havent seen your individual setup.
*
Well, if there is a lawyer that willing to take this case, I already filed a law suit against them.
Even a lawyer from DAP also said this cannot be a case as there is no government certified third party independent company that can confirm the meter's accuracy. Or you want me to look for an UMNO laywer to sue his boss?
File a law suit is easy, but winning it is another story.
This is just like some people won in Indah Water's case. But did they specify clearly how they won it? Most of the people that won on such law suit is mainly because their "dirty" water a routed to a tank rather than routed to a Indah Water's facility. And Indah Water are charging normal rate to them. So for such group of people they just only need to provide their floor plan and other legal documents and that's it.

seriously you are going all wrong. why stroll to a pary lawyer? what for?

you file a small claims suit in your local court, provide evidence and serve a notice, wait for TNB to reply and then continue. you do not need (nor are you allowed) a lawyer in small claims court. max. damage to you is 100 RM court fees.

to win a law suit you need to have evidence and an argument. i told you before that your evidence and arguments are not good. that's your problem. you dont need a government certified blah - an expert testimony and witness statement is good enough (i.e. get someone from the field to check our your situation). if your evidence is good its TNBs job to proof you wrong. going for political parties for support is the wrong way to get anything done. personally i see the quality of the politicians in malaysia and i feel very sad. the incompetency and lack of knowledge in pretty much everything is sad and frightening and it persists across all parties with one no two standing out in this ocean of incompetence. but all that is irrelevant to a court case. try to read up on it instead of ranting around.

all that*s needed is your willingness to act if you feel someone it doing you wrong. small claims court is easy and even a laymen can get through it. the court helps and advises you. trust me if you have a case the court will be in your favour. been there done it. bank went against me with one lawyer, saw i had good arguments beefed up with 3 and in the end 4 lawyers, still they lost on all grounds and had to fullfill all my demands, i only was asked to skip the demand for a public personal apology in a national newspaper. as part of the settlement this was moved to a public apology in the bank's branch in front of all customers that happened to be there. mind you all my contract changes and damages demand had to be met and they paid me my court expenditures too.

so to sum it up: if i had actual evidence (which once again i dont think you have, gather proper evidence first) i would send tnb a warning and then sue them. we actually need more consumers to go and sue irresponsible companies. but only if there is a case.

Well, it is easy for you to say. But again if 100% I can win then only I go for it. Else I won't waste time on it.

I never complaint, just to let more people know on TNB's dirty way of making money.
Does verbal statement from a TNB contractor's statement carry any weight? You think of it.

For effective natural ventilation, with the roof open fully also useless.
You need to make sure the ceiling are flat, windows are opened.

and yet i don't see any of the housing development projects giving any warranty after 1-2 years.
this one is willing to cover 20 years if should there's any crack on the wall.

i see lots of housing over here have crack forming on the wall under a year.
some people say red clay brick have better insulation against heat by sunshine. better cooling effect.

wife says red clay bricks have better heat retention ability, thus frequently used in western countries. they absorb heat during the day, making the house cooler during the day but they excrete the stored heat during the night. thus heating the walls making it warmer. a welcomed trait for western countries where night time is very cold and it would reduce the heating costs.
not exactly an appealing proposition for the weather here.

anyway we're planning for AAC bricks for the west facing walls to improve the insulation. it's only ~60 feet of walls that face the evening sunshine. and the rest of the house probably the normal cement bricks. undecided yet.

Main structure and wall are different.
Walls warranty coverage is 18 months while main structure is lifetime.
This is government's requirement.
Also, red brick's quality also are quite poor, it will expand over the time, especially if it expose to water frequently.

I think these cracking is due to either workmanship, not enough vent for an extended period of time & external work which vibrates and shifts the alignment even so slightly. As far as workmanship is concerned, it will be best to refer to your friends' houses finishes.
I'm impressed and enjoying your work TS, keep it up.
Personally, i prefer red brick, not sure whether red brick or cement is better.
U might use "double wall" to better vent the house.

Brick have problem, the sand/cement ratio not right and using poor quality sand.
Building a 22*75 double storey house only need rm90000-100000 max, if the materials are sourced in bulk, it will be cheaper by 20-30%

Wall break the roof won't really collapse, but pillar breaks, you know what I mean.
BTW, I think I never ask you is the land flat and stable land or reclaim land?

if AAC is cheaper i might just go with AAC blocks just for the west wall.
if not have to consider double bricking that wall as i did to the HT room.

if even that is too expensive i just consider double bricking the master bedroom wall. but seeing that we have lots of 7'x7' windows, brick cost can't be that much anyway.

Solid or not? That's more important.

care to explain why a horn setup will solve this null?

Tapped horn are used to make a small woofer sound big. Like a 10" can sound like 15" with this concept.
Simulation won't be accurate most of the time.
Have to know that, music are dynamic, so I won't trust simulation most of the time, trust your ears.

a tapped horn will be even worse in this room. tapped horn have a fundamental null at 100hz-150hz. it's not suggested for rooms where freq above 100hz are required from the sub.

simulation is pretty accurate when it comes to soundwave. even tapped horn design process are heavily dependent on the hornresp predicted responses.

see that null? it's not gonna improve the room null that's already there.

room response could be accurately predicted. refer the paper "Subwoofers: Optimum Number and Locations" by Todd Welti, Research Acoustician, Harman International Industries, Inc.
my own testing shows the room simulation could predict actual responses to a high degree of precision. findings are posted before in the audiophiles subforum.

can't trust my own ears as the room have yet to be built. so it's all simulation to avoid building a problematic room.

If in this world all speakers having the same spec, sound same, all human ear are same then I'll agree with you on this.
Sound wave are travelling in wave form, so the placement of the microphone plays an important role. Not to mention is that microphone calibrated or not hmm.gif

Look on those numbers, it never state what type of sub being used? I don't do measurements most of the time, so I won't bother to know this, haha.
To manage a dip, there's more to be done other than just keep on looking at the graphs.

it's normal for contractors to ask for >RM100 for a complete build. usually RM120-RM130 psft including tile, ceiling, paint, etc.
mine at RM32 psft, but there's no roof, no windows, no doors, no bathroom utensil, no tile, no wiring.

pretty much the basic structure only. we're gonna be our own main contractor. it's DIY from start to end laugh.gif
it's a dual 15 inch ported sub tuned to 20hz. each powered by a 600w class d amp.

null because of the sub response, or amp response could be corrected. but a large null because of the room could never be corrected by a brute force solution. i (we) have experimented to correct a huge room null by giving the sub 4x the power, it only improves the response by 2db. 400% more power, only ~5% correction.
*
I don't know, I assume that both sub are placed together? If yes, guess they are self cancelling each other.

yes. the roof is very large indeed. roof rafter length is longer than any roofing guide that i've read.

what do you mean with the rainwater piping? do you think a single drain pipe (per side) is not gonna be sufficient? i was opting to collect the rainwater, thus the single drain at the middle span.
the roof drain pipe area is marked with yellow in this figure:

You are collecting rain water for what?
No matter what it is, must consume it fast and cover it properly, aedes likes rain water very much.

rainwater harvesting. will be used for plant irrigation and toilet flushing. ground level collection from the drain pipe will be stored inside this:

or something like it. which will then be pumped into storage tanks inside the ceiling structure (marked blue in the previous figure).

there's enough space on the ceiling slab to store 12 tonne of water. no that's not a typo.

Good concept on conserving water, wish I have a bangalow or semi-d to do the same.
Still make sure the top tank is covered type.

You need to have 2 level switch to stop the pump, 1 from the collector tank and another at receiving tank.
