SubscriberI was discussing alternate energies recently with a zealot, who told me that trigeneration was the next big thing.
So I googled and really couldn't find anything except PR stuff from either the city of Sydney or promoters continually saying it was 85% efficient vs 45% for coal fired power stations. Maybe so but what is the cost of utilizing that 85% of the energy /gas input?
What I couldn't find is how much a KWH it costs vs good old mains electricity even using their estimate of 83% price rise by 2030.
From what I saw on the site for a North Sydney Building, the capital cost seems enormous AFAIR 1.8million for 477KW and 265 KW of airconditioning plus a small amount of heat. I did an in head calculation and 700 1Kw Chinese generators would be cheaper LOL.( though not as good for the environment methinks.)
Does anyone have some balanced information on the pros and cons and what the actual costs are?
It seems to me that Power stations became big and remote for good reasons and that is why Pyrmont and other small power stations closed.
It seems to me that plugging a heap of internal combustion engines attached to waste heat airconditioners in buildings could be retrograde vs say energy conservation (via LED lights , auto switching , and low current draw modular air conditioners with zone control)ie intelligent buildings using distributed power either from dirty or clean sources.
BTW, as long as I don't have to subsidise them, I have no opinion one way or another, but I guess it pains me to see energy conservation possibly go away on yet another tangent.

Plenty of comment on it, eg here:
Sydney trigen? Try again with renewables : Renew Economy
One comment
It’s great greenwashing PR for the gas industry, though.

We have some involvement with trigen in our business. Yet to hear about one that works as advertised, for reasons technical, design or operating cost.
One reason they are popular on new buildings is that their inclusion goes a long way to upping the NABERS rating.
RoverLord
Just had a flick through the NABERS site and decided...
What a load of snot.
they've upped their scale to 6 stars because
"it lets us identify market leading building" but "a 6 star rating produces less than 50% greenhouse emissions"
so what is it? A clearly defined number set OR a relatively graded set?
Whose going to handle the Admin on re-issuing everyone new certificates it if its a relatively graded set and someone does something new and better?
If its a clearly defined number why aren't there more? what happens when someone exceeds the definition required for 6 stars?
Dont get me wrong Its a great idea but I'll be paying about as much attention to the NABERS scale when it comes to selecting a building as I would to the logie accolades list when it comes time to pick a partner for surviving the zombie apocalypse

NABERS is big business these days Dave, and a boon for us in building controls. The move to six stars is to make it harder for buildings to achieve the top rating. Technology and design has improved a hell of a lot since this started just a few years ago so I suppose its just pushing the boundaries.
Bit like economy and emmission targets for cars I suppose.
RoverLord
ahh yes much like ancap.
smart cars rate higher than landies on ancap yet more people survive accidents in landies than do smart cars.

As far as I know, there hasn't been a proper carbon cost breakdown on the production of the Defender versus something like the Prius.
My opinion is the jury is still out regarding whether new tech cars are in fact cheaper top produce carbon-wise than old tech cars.

Perhaps if more small hatches were built with heavier chassis, had diesel engines and weighed 2.5 tonne, we'd have less accidents all round.

Arnie ("I'll be ba-a-a-ck") the Govern-ator was supposed to have commissioned a study that showed his Hummer as having a lower carbon foot-print to manufacture, than a Prius.
It must be true 'cos I read it on the internet...
