OT. Information on pergola slats to allow sun in winter?

If I was at work I could tell you. Google anything to do with solar advantage/energy efficiency and you should find the answer.

Make them adjustable! Then you get the best of both worlds. Spring and Autumn can have extra warm days with sun lower etc.

Winter sun in Melbourne?

John,

This is the complete opposite of what your asking, but at the Hall in Birdsville, they have erected awnings on western side of the hall, using "Zed" purlins as the shading material.

Lets plenty of light in, but adds a lot of shade, without "storing" the heat underneath. Don't know if you could use this idea at your place, with all the info you've obtained above.

Something on TV today about 6 star homes in Melbourne, all very solar friendly.

Hooroo,
Bob.

Thank you all for your information, ideas, links etc, plenty of food for thought, big thank you.

Hi John, Just a different look at the same thing.
In Perth, we have an outdoor spa with an open pergola, which we have covered with a Wisteria 'vine'. It grows a full foliage in summer giving us cover from the sun and loses its leaves in winter allowing the winter sun through. Probably a lot cheaper than movable pergola slats. You just need to keep it trimmed. It also looks good most of the year.
