Design Research: Get it Right with PreDesign

This is an amazing Architectural Design Toole that I have been waiting for for years -it is truly innovative not gimmicky and potentially a real help to clarify Climate in Design -many thanks -sadly I am near retirement ( I am a Building Designer /Home Energy Assessor) so this has come a touch late but will benefit my communication with Clients immenseley -many thanks
Question -does the Design Toole take the changing effects of Climate Change into Account -eg here in Australia many locations have become hotter since the 1970s? -our Climate Data is out of date !!!

Thanks for your kind words, Dean.
To answer your question, the analysis is based on the same hourly historical weather data that consultants use for things like energy simulations and the like. It usually represents typical years based on what has happened in the past.
You can see the data we’ve used for Australia here: http://climate.onebuilding.org/WMO_Region_5_Southwest_Pacific/AUS_Australia/index.html It’s relatively recent - not too many weather files from the 70’s! Most are from the past decade.
I’ve noted your request for future weather data to be added!
cheers, Andrew

Not exactly for windows, because windows give free solar energy. Triple glazing affect transparency and solar transmission factor (a lot).

There is a lot of code in the world, some are most interesting from countries involved from a long time in saving energy. There is also international ISO standards and thermal scientific laws.

On our parts triple glazing is the norm, and the more environmentally conscious install windows with four panes of glass. In a house not designed for solar energy, the times when a window brings in more energy than it wastes tend to result to a need to use cooling in the room…

It obviously depends on the location and the climate. That’s why there are different standards in the world, different practices.

On the other hand, there are other subtleties. Near where I live there is a large, famous and luxurious condominium, built in the late 1960s. There is absolutely no thermal insulation and large single glazed windows.
This property should be rated very poor thermal performances, while it is rated… medium. Because there is an ideal architectural form.

And it’s not just thermal insulation, there’s the issue of thermal inertia, depending on the type of climate…

Do you have plans for a user flow to design solar installations: show the solar exposure over the year for each external surface ?

Not to say that these new things are bad, but i really think sketchup is all over the place… I can’t find things that would make me exited about sketchup in years… I would love to see soft shadows in corners (Like vectorworks), that would be an improvment of the visuals, I would like to see a component like feature in layout. i would like to see sketchup and layout handeling large files a lot better, i would like to see layout not crash wile exporting to PDF. I would like to see great improvments on layout’s snaping sistem…The new icons are not going to do that for me… I like sketchup… but it’s getting hard to take it seriously

Hi Richard,
I can’t talk about our future plans unfortunately but I will note that down as a feature request :slight_smile:

best
Andrew

can you please also note this down?:

Does this mean available to subscription licence holders only?

I wonder who will benefit most from Predesign? I can see that if you are a company with worldwide, or even continent-wide, ambitions, it’s a useful source of climate information. But for those of us working in a small geographical area, I’m guessing it would be less so - in that, every project would display the same climate characteristics. Or have I misunderstood its purpose?

Agree with Simon. “Predesign” means so much more than energy analysis. Locally we know the methods that are used, and understood by local builders for energy conservation, then in design development the analysis is done based on California energy standards, which, along with CALGreen, will bring many more requirements into the project; more, frankly, than the owners or builders wish to do.

This could be helpful if it can provide some heads=up on general decisions such as siting and orientation (and actually show where a choice helps or hinders compliance).

Perhaps the most important use case for PreDesign is to help architects communicate how the climate affects a project to their clients.

Often people need to prove they have done some analysis to support that conversation. This gives our customers a way to do that easily, even if they already know about the climate themselves.

I like the idea of being able to show this information to clients - kinda like the traditional site / climate analysis map - is there a way to download / store it as a presentation, or to insert things into layout, or do we need to do screensnaps? Or just show it to the client in house?
Thanks.,

The options available now are essentially a live demonstration or screen grabs. We’ve already had a lot of requests like this though so it’s something we’ll be doing research into once people have started using the app so we can get more information on what could be the best ways to do this.
