Thanks Mark, appreciated.

Hi,

Would it be sensible to maintain air flow (possibly to increase it) so as to wick away any moisture from the ground, then to add breathable insulation to the floor. This would stop any moisture being concentrated in the timbers. Never a fan of using nonbreathable insulations where natural products are being used. Breather membrane with cellulose insulation, or wool / hemp / wood fibre with supporting mesh?

We have just received a small grant from Environment Wales in order to create the WIKI. Once the basic format is up we shall be looking for contributions. If anyone is keen on getting involved in the new WIKI either by helping to generate the format, or by publishing case studies etc please contact me (Peter Draper) via the Rounded Developments website – http://www.rounded-developments.org.uk
Cheers

Hi Chris,

RDE is also a not-for-profit organisation and our remit is to champion sustainable building in Wales, so we would agree that it needs to be robust and, of course, free to all. The commercial side would be something that might happen anyway off of the back of it, but we were not looking to make money from the exercise.

If the AECB wishes to host then fine, it was something that we thought would support our efforts to promote sustainable building, and also have the knock-on of bringing people to our site.

Wherever it sits it will require contributions from AECB members, so there will need to be support from AECB in order for it to work. As you will know the actual setting up of a Wiki is simple enough, it just needs some though about the structure of the site so that there is a common thread running through all of the data. After that, we were looking for it to take on a life of its own with minimal amounts of support / moderation.

Once launched we would look for some publicity in Green Building and also contact various orgs that we know would be interested.

I would wish this to be very much a stand alone peer-reviewed and led project, as we do not have the time for providing day to day moderation etc.

So in a way it makes little difference where it sits, as people like yourself and Chris can be registered as moderators and it can be accessed from anywhere. So it could be badged as AECB and RDE and we could host. As a small social enterprise we would wish to get some mileage in associating RDE with the project, especially if we are kick-starting the process.

Thoughts again welcome.

Cheers

Dear All,

The original conversations with Cardiff University were aimed at getting an online U value calculator for natural building systems based around different standards. So people could go online and put in, say a straw bale house and get the thicknesses, detailing required in order to comply with Silver, Gold, Passiv haus, Part L etc. I think that this is still required, but the conversations then went on to the need to show detailing of structures etc as well. So the idea of the Wiki was born, so the people could edit / add details, calculations etc rather than trying to create a whole new project that would take a lot of time, effort and cash (esp, if the U values were anything but indicative only).

The benefits of the AECB forum were talked about, but the issue with forums is that they provide a dialogue rather than a set of necessarily reliable data. So the format discussed was this Wiki with a whole set of pages dedicated to different styles of building and people's experiences and calculations to go with them, after all people have had to produce calcs for building regs etc. With this as a backdrop, it should encourage people (architects, developers etc) to feel more confident with the different technologies and options.

CLP is still ostensibly an energy standard and a Wiki is needed to start to address the issue of how to reach the standards using natural materials rather than conventional ones. It would also address issues like extensions / conversions on existing buildings rather than just new build.

I am happy to create and host the Wiki via the Rounded Developments Enterprises website, I am not sure how this would be done via AECB. It would rely on AECB members inputting a lot of info and drawings etc in order to make it a viable source of info, so it could easily be linked to via the AECB website or vice versa.

Ultimately it was suggested that specific drawings could be made available in CAD format via the Wiki (and Cardiff Uni might run a PhD on how to do this). Bath Uni would also be interested in contributing data etc to the Wiki, which would be nice and it could take the info to a new level.

There is a commercial opportunity here as well, since all drawings will be either generic or specific to an existing building and so developers may wish to commission drawings from contributors to the Wiki for their particular project.

I hope that this makes our initial thoughts clearer.

Cheers

Peter
