@solarventi, Hi, sorry, I didnt work it correctly, It is an interesting concept, but I am not getting it>>> bit slow... How do you heat up in winter in Vic when we get very little sun and the weather has turned Artic this year, Main reason I am noticing the cold, especially when working outside. I do have low blood pressure so feel the cold, but the red clothing next to skin works a charm. I would like to understand... I have seen on uTube where they DIY passive heat I liked the pictures but no explanation and these were using exisiting windows .. I this with gap at bottom on outside so cold air comes in and gap at top on inside so warm air into house.... but got to technical for me. And I get confused, as hot air rises and I dont understand why fans are at the top in newer models not at bottom [of heaters] But I would mind understanding how it works.. Am going to check the website, TU very much. I have bats to put in kitchen reno but would like something to attach to the corrogated iron so there is no gap between iron and bats. Appreciate your help and will check again on your site to see if I missed anything :)

After I had finished my Archi Masters I was working for an architecture firm who also did a small amount of work for a volume builder. They were actually a pretty good quality builder and at least got the orientation of their 'pre-designed' plans correct. We had the ability to make minor changes to every job and it pained me to see so many simple to implement passive options not being incorporated. Had most of their clients known that they would be saving MONEY over the longterm by making a few minor changes to suit their site, they all would have done it. The problem is unless someone can sell this idea to them as a financial/lifestyle choice, many just think it is about saving the world. It is a no-brainer if you have in interest in it, but for those who don't know, there is no-one there selling it to them, especially on the lower end of the market.

our Solar Skylight (not Solar Tube) has a panel on the ceiling that connects via a fibre optic cable through the roof space and comes out under the ridge capping to connect to a small Solar panel up to 9 m away: there's no disturbance to the roofing and no shaft between the roof and ceiling...the Illume Brand (with the widest range of standard and custom sizes) was not available locally so we installed DIY Acol or Ezylite brand Solar Skylights from Bunnings for about $300. installed in less than 1 hr by a confident handyperson and no need for plumber or electrician. We're delighted with the extra light, especially pleased that we haven't created a potential leak point in the roof and have just ordered some more

My house is also built at the top of a hill, the summit and is cut into a cliff. We bought it, it was built in the 90s and the orientation is entirely wrong. The living areas face west and all bedrooms are in the east. The master is exposed to the western and the northern sunshine. It’s nice in the winter and entirely unbearable in the summer. The same goes for my living room. We take extra long holidays in the summer to avoid being at home. The home had no insulation in ceilings, and raked ceilings. So the first thing we did was remove the roof sheeting install battens to create a cavity and installed R3.5 insulation. We are also upgrading installing new windows to upgrade the glazing on the western windows and looking to put insulation in all the walls It also gets really windy, so windy. So I understand your concerns. When it gets windy the entire house shakes. So the next thing will be to improve the bracing. There is a 3-4metre clearance under our home for storage. We could do a build in under. Even with the positioning of our shed and close proximity to the home it does little to shelter from the wind. We are considered the building an “outdoor room” which would act as an alfresco with skylights, lounge, pool and kitchenette that could act as an outdoor entertainment area when weather permits. I just did a sustainable design for a client nearby. I am so jealous of her amazing home. Her land is smaller then my land and her land cost the same price as my house and land. So I am grateful for what I have.
