Eco House

[alfred98]

Anyone got this idea for a house.....or know someone who can help build this kind of house in Malaysia????

[athena]

i think Setia Eco-Park is one township which offers the Eco-house...do check it out

[Fishingman]

What is a eco house?

That's in KL.......I mean can get builder for CTA1.....site
What is a eco house?

Self sustainable house......using rain water, solar power and wind to generate electricity for own use at least!!!:)

[athena]

you want to custom-build one in S'wan??

[shiruikage]

hell...i also wanna build a house like dat.

[Dino]

Solar panels are going to costs a bomb.

That what everyone being tell........but what is the actual cost????:sus:

[Dino]

That what everyone being tell........but what is the actual cost????:sus:

One panel on the roof, if i am not mistaken costs about USD$3-5k. So to sustain the whole house, and depending on how much your Karaoke machine use, may be looking at about USD$20k minimum....

that one produce electricity directly ar? what about solar heating panels?

[Dino]

Yup, electricity producing panels. Solar heating should be same kua......you need electricity to heat the water.......:unsure:

[Zazu]

have anyone called the contractors regarding the pricing?..
i went to the malaysian energy project and found this list..

Don't think about producing your own electricity for the time being. The cost of electricity would be doubled of those off the grids if you tool up for it's production in the long run.

There is only a limited choice for you in electricity generation. It's either solar or a genset. There is not enough wind in malaysia to make a wind turbine viable. Try running a diesel generator on cooking oil. That would be cheaper then solar panels and batteries.

Assuming you run the aircon the whole day, the first few things to consider is the insulations. You should build the house with double walls on the outside facing the sun, insulator and reflector lined roof, minimal window area, double glazing, automated blinds, etc etc depending on the design of the house.

Lighting can be provided by fiber optic.

Water collection consist of gutters, storage tanks and pumps. It's good for washing cars and gardening. If you want to use that for drinking, then invest in a water purification system. Lots of piping and pumps but the average plumber will be able to sort everything out for you.

If you want to go green, then consider processing your own waste. Water can be recycled. A green house or garden would help in both instant.

It's about how much money you want to spent. Designing the house it not the problem. If you want to build it in a cold climate then there are a lot more you can do.

no, the solar heating panel i'm talking about is the one with direct heating of water thru pipes exposed to concentrated sunlight.

Thanks singteck!!! Got some idea like that but not in full scale as the cost will be $$$$....What about solar panel to generate smal time electricity to pump up water......or to run washing machine.....just small....time.....good idea right....I was think small scale wind turbine for pumping water or some thing....using cooking oil is still bad for the environment....what about biogas.....from waste to heat up water or for cooking.....I don't think we do this enough in malaysia.....the onli problems facing probably cannot get local contractor to do this...:cool:

Here's some commercially available solutions for your eco-home:

Solar water purifier: http://www.sunsurewater.com/
Solar panel tracking: http://www.solartracking.com.au/
Harvest rainwater: http://www.everydropwaterharvester.itaustralia.org/webpage.html

Got the above from watching The New Inventors show... ;)

[Dino]

Over here, there are some areas whereby if your home solar panels generate more electricity than you need, power companies will buy it from you.

In Malaysia, there is this Suria 1000 programme.
Not sure if this is applicable to private homes but worth to check it out: http://www.mbipv.net.my/suria.htm

Malaysia have all the expertise required. You just need to find someone to organise them for you. All these are used in industries, but never in homes.

The problem is with diminishing returns but you can't put a price on planet earth. So if you can afford it, by all means do it.

Solar panels can power all your appliances and you can always top up your power requirements from the national grids. You can used all the power from the solar panels and batteries and only switch to the grinds when sensors detects a need.

If you have enough money and land, you can always built a solar collector to generate power and feed it into the grids and make some money out of it.

Water heater can be made with some copper tubbing, black paint, small pump, temperature sensor and an insulated water tank.

Unless you have area to house a 100' tank, you will not produce enough biogas for cooking. Gas off the shelf is a by product and if you don't use it, it will be wasted and burned at the wells. So I don't see a need to produce biogas for home use.

The key word is efficency.

Day time lighting using the sun for source and fiber optics for distribution. Night time lighting using batteries charged by the solar panels. Use more LED lights but the colour is a little sickening :sick: Install an automated home lighting system to save more energy but I find them a little annoying. Hate it when I have to get up and dance when they automatically switch off the lights because you have been sitting down for too long. Worst if it happens when you sit on the potty :squeeze:

Have you talk to an architect? They can design all the things you can pay for :laugh:

Wah.... very good idea.....u r dwelling on one of my fav topic.....got the will and $$ power to see it through? You are looking at one renewable option....I suggest in all renewalble energy idea, you need a large piece of land, at least 2 Hactares.....cos it take so much of land foot print in tropical region to sustain an eco-freindly family. Otherwise, you will be considered a inconsiderate neighbour.

For example, how about looking into producing your own methane gas using all the waste geenrated by your compound and your family? Install a micro-turbine and coupled it with a wind mill to give your constant power supply. Or you can consider a running a modified diesel engine that can makan crude palm oil........this is if ur family are heavy user of electricity....

But to really want to be eco freindly, u have to think of cutting ur electricity consumption......e.g in heating and cooling...no karoake.....no fridge/freezer...no air con....boleh tahan tak? The best house is to build ur house into the earth. Like living a big Gua Niah......only need ligthing...and u get LED type of light...solar power is enuf to power ur whole house....

Then use the methane gas generated from ur waste decomposition for cooking.

Then use solar to give hot water to take bath....:)

building house into the earth.. actually that sounds like a great idea.. since M'sia is forever hot... but then.. have to find a way to deal with floods...:p

build a house on a higher ground and then cover it with lots of earth like a small hill.....:)

Flooding is another issue that Jabatan Taliair to take care...beyond this discussion at the moment..ask LZ for more details since he is expert in this area...:)

Thanks singteck....wah U are really good in this thing hor!!! So far my idea....to build a house....with underground storage......so call in west to collect cold air.....double and insulated wall.....double something windows.....roof......place for gardening......and part for solar panel....large tank with water supply from ground.......pump using solar or wind turbine drinking water using filter system.....as for waste..then if can or feasible.....use for kitchen cooking or water heater using gas one ah!!! cheers...go green!!!....I don't know what happen to me....but I'm thinking about it everyday...including in the dream.......maybe because watching too much discovery channel!!!!:unsure:

no...this method is too inefficient. there will be lost energy at at least 2 points: one at the solar collector panels where the efficiency is ony at the most 15%, and two, at the steam turbine, where the efficient is around 50%-ish?

what i'm talking about is this:

i saw several houses in sitiawan using this method many many years ago...and i thought...hey, at least at night got hot water or there's enuf hot water for milo every day.

ohh no no no, u misunderstood me. the inefficiency one is for those direct solar converters de. those that produce directly electricities de.

the efficiency of the solar heater is much higher.

sori....if we all into DC current, the technology today will make our renewalble energy conversion to become efficient.

anyway... I like one proponent that want us to use DC electrical appliances in our homes...I agree with him but where to fridges, computer and karoake sets works on DC current?:)

generally u will find that most DC machineries are smaller than AC as their safety features are lesser. Due to some fight between Edison and Westinghouse more than 100 years ago, we r now saddled with the conventional mindset that everything should run on AC that comes with lots of safety protections. U may like to tell your neighbour shop owner to go into deeper into the product.....and see if it really cheap but useful fan?:squeeze:

Therefore, if you are super super rich, I happy to help you start a new community that have all electricity generated to DC and have all the loads using DC....provided u can find suppiers for ur gadgets in DC....

with this strategic change of ur energy generation and consumption, u can harness all the energy you want from Wind, Wave, exercise machine, Dino's new pp paddle, etc etc to build your real eco house....:):)

[LaoZhang]

A traditional Malay Kampong house is near enough to be termed a M'sian eco house.

Timber house on stilts, attap roof, timber louvre windows.. surrounded by tall trees... well water, outhouse for human waste which are recycled as fertilizer.. Fan instead of air conditions, self made water filter etc

Cheap to build and maintain..

of course could be improved with more science and tech !

i found out that to power the average 4-room HDB home, you'll need to spend approx SG$30,000- 35,0000 on solar cells and batteries. (and that's with no air-cond)

this particular HDB home averages SG$1,100 per year in electricity tariffs.

let's say $33,000/$1,100.. it takes 30 years to break even the initial cost of installing your home with solar cells..

of course that's assuming you use the current conventional 25% efficiency PV cells and that you get 8 hours of good sunlight per day.
