Well imagine this - a hot water bottle - makes you hot - why - the hot water heats the rubber bottle and the air around it - so you get hot. If you put cold water into that bottle - what does it do? It makes you cooler. re my first post. I just think that some "experts" out there are actually just learning how to make a sustainable house and maybe they are just being a bit too "technical" in their approach. Sure some it is required but don't get too wrapped up in their technology being the best there is - lots of people out there are learning about this stuff. Steve Yak_Chat Yes I understand the hot water bottle theory. However I am not clear how they are generating the cold air i.e. what type of pump. I am not convinced they are being too 'technical' nor is anyone claiming they are 'experts'. Rather they are trying to create a system which is very much in 'harmony' with the environment i.e. cooling for summer and heating for winter. Yes there are many people out there creating systems - some are better than others. Beetle Re: Final Working Drawings and air transfer systems 10Sep 28, 2007 8:20 am I think Yak_Chat might be saying to look at the actual house itself first to get the greatest efficiency - through correct design and orientation (living areas to the north etc.), correct eaves, different materials etc. etc. - before looking at the technical stuff like hydronic heating or underfloor cooling.
(sorry to try to take the words out of your mouth Yak_Chat) After 2 false starts, a year living overseas, two more world trips and 3 years of uncertainty we are now starting the build process again - hopefully for real this time! Re: Final Working Drawings and air transfer systems 11Sep 28, 2007 7:46 pm Thanks Muzzman - No offence taken Looks like I needed helping hand -
Maybe the glass of wine, my fingers and brain were being a bit to obtuse last night Basically I think a good sustainabke house should be that - sustainable and should use as much natural method as possible to assist with cooling and warmth. In my experience and I do know a few arhitects - professionally and personally - many of them love to grab the latest "products" brochure that they get sent every month as part fo their industry subscriptions - and then they love to put this wonder thing into their next design, when that might not be the best thing for the job - but it gets them noticed on the awards night FYI A basic description of the hydronic heat/colling system can be found here. http://oikos.com/esb/53/hydroniccool.html It's basically a fridge ro heater that can make the water hot or cold. But as said earlier - or was it just that I thought it With the right trees planted near the house and sunshine coming in in winter - openeing window to let cool air in when it;s around you can minimise any external methods of heat/coling. ie Manually heating or cooling the place should be a minor part of the design - if at all. Here is an article on an office building (in VIC) that does just that and uses natural methods to assist the temp of the building. It also uses a hydronic type system to cope with the body heat of the workers during the day - but they also integrate natural systems. http://www.abc.net.au/catalyst/stories/s1901482.htm#transcript Beetle - I am really impressed that you are on the path of building a sustainable house and it is pioneers like you who will be seen as forging the way for the masses. Steve Re: Final Working Drawings and air transfer systems 12Sep 29, 2007 11:24 am Thanks very much for the information Yak_Chat
I understand what you mean and I probably wasn't too clear in my first post We have looked at all of the options you mention (shading, eaves, thermal properties of walls and floors, venting, windows etc) to make the house as sustainable as possible and the last items has been the heating/cooling for those extra hot/cold days. As much as we would like to think we won't need to use it, my guess is the house will take a lot of heat load on the upper story due to the orientation (north east). My apologies if I mis-read your response - I must have been having a dim moment (or was it the scotch!) The information is great and much appreciated.

Seeing as your building double story this might help. I find in my place - which is double story - that winters upstairs are just super , warm in the morning, great in the afternoon and very pleasant all round given I have some very poor thermal areas still as i improve the place. Downstairs in winter is a bit cooler but I'm currently working on pretty passive solution for that to help in winter. In Summer - yes upstairs is a bit too hot - but downstairs is fine and even with those really hot days in summer last year - without any cooling - it was still 10 degrees lower than outside due to my shading verandahs etc - and with a bit more passive colling planned - I reckon It wil all be livebale - ala natural - by moving around into the rooms as required and living with nature. You might also find this a useful link. http://www.aeoogle.com No it's not a typo Google has a eco (alternative energy specific products) search engine that will prioritize your search hits with eco related web pages. Nice I'll post it under eco living and see if the mods will make a sticky of it.
