Building Clarendon Brighton - Done and moved in Sept 2009 Re: Type of heating/cooling required for a double glazed house 22Jan 26, 2009 4:37 pm I think you will find those pavers a troublesome heat source in summer. facing N and NNW they will get very hot - especially after a hot day - you'll be wanting a nice cool seabreeze to come through the outdoor entertaining area and the pavers will be pumping out heat till midnight on you.
Make sure you put lots of windows in your upstairs bedrooms to get some cross flow or they will be hotter than hell too. Awning style windows work well in upper levels - no rain gets in - but the rooms can be ventilated all day. Re: Type of heating/cooling required for a double glazed house 23Jan 26, 2009 5:52 pm The driveaway and parking of my new house will be on the North side, with Western exposure in summer. I don't want them to be a heat store, so I'm planning to use the plastic mesh permaeable paving:

The council doesn't seem to like the idea though, they put "brick paving, etc" on my planning approval, but I'm going to argue this with them.

That doesn't sound good at all! What about planting a medium sized tree, maybe next to the stairs? Will that help by providing some shading? If so, any idea what type of tree is best?

Yak_Chat, thanks for the suggestions! I am just not quite getting there yet The house is actually on the higher side. The turf area is actually about 0.5m drop in elevation. So, I just need to make sure I don't block the airflow above the retaining wall, I should be ok? Or, you are actually suggesting raising the turf area?? Building Clarendon Brighton - Done and moved in Sept 2009 Re: Type of heating/cooling required for a double glazed house 27Jan 29, 2009 12:14 am I was more thinking the paling fence on thr RHS of the plan. that is NEastern side which is where the typical sydney seabreezae comes from.
Being 1km from the coast that should get to your place and I'd be suggesting you want to make sure you do not block it off. go stand at the block for a few hours on sunset and just after and see where the brreeze is comming from when a NE is blowing. And try to make sure that direction is free to flow in your final plans and gardens. Steve Re: Type of heating/cooling required for a double glazed house 32Jan 30, 2009 9:16 pm Ok, so to get back on to the "cooling a double glazed house" topic (and yes, i'm unashamedly using the thread for my own purposes! )...
In the house we are about to build, we will have a fair bit of double glazing with NW/W aspects from our main living area and we are concerned about needing additional/artificial cooling in the hotter summer months. The whole house has been designed to limit the need for artificial heating/cooling...so in that area we have additional awnings to try and reduce solar heat gain in summer...a fair bit of cross ventilation...and im planning on specifying Low E glass for the north facing windows...but, is that enough? The main living areas will have raked ceilings and the whole house will be double brick (external walls)...so we really want to decide about any "air conditioning" up front, rather than have to retro-fit something later! Also, we don't really like the idea of ceiling fans... Oh..and we're in Canberra..!! Any thoughts or advice on cooling in this situation would be appreciated! Thanks Adam Re: Type of heating/cooling required for a double glazed house 33Jan 31, 2009 7:46 pm Get over the like or not of ceiling fans - and make sure your ceilings are insulated well.
Making your house - comfortable to live in - means a few things need to be compromised.

Its fairly similar to the one we are building except that we will be in a cooler temperate climate and you have invested in more thermal mass. You will get close to minimal extra heating and cooling but it will be hard to dispense with it in times of extreme weather. Even Dan Chiras from his book The Solar House reckons that you will you can at the most reduce heating/cooling requirement by 90%. It will be up to you whether you want to use strategically place space heaters/coolers in certain room (combined with some fans and ducts) or go for a central duct system. We decided on a ducted inveter multi-zone RCAC simply because we could have either heating or cooling as one unit and choose which rooms needed it. It is a big investment that may not be needed that often. We will still attempt to operate the house that minimise our reliance our heating/cooling use. But remember there is no such thing as a free lunch - no sun = no warmth and no breeze = no cooling. Even this Adelaide heatwave is going to test most energy-efficient homes. I heard that even the Hobbits in Coober Pedy are beginning getting a little uncomfortable with this weather.
