Generally, when looking at economic changes, it is usual to look for similar situations that have happened in the past, and then extrapolate from that. I am sure someone in the ONS and the Treasury is looking into the economic situation of building. This may be part of the reason that they are going to review HS2 again. Even though these statistical methods are not perfect, as mathematicians say about statistics, 'they are wrong for the right reasons'.

So purely speculation, on the future price of building materials?

Generally, the value of out currency, is impacted by the value of the USA and the EU currency. So we still have the currency issue to deal with. Importing from non EU countries may sound like it is going to be easy, but it does depend on what other arrangements they have with trading partners. So none of it is as clear cut as we like to think.

Okay, taking that at face value, can you point me to where it says that the opposite is going to happen to the price of building? I expect some reports from respected, or at least well known, agencies, not the rantings and spoutings of politicians or political pundits.

Room air temperature/quality sensors
SteamyTea replied to dnb's topic in Networks, AV, Security & Automation
Can you do some plots of RH against CO2, maybe of short, medium and long-term time scales. -
Room air temperature/quality sensors
SteamyTea replied to dnb's topic in Networks, AV, Security & Automation
Outside temperature and humidity will make a difference, but should be able to compensate for that easily enough I would have thought. Those DHT11s are rubbish, even at a quid each. I still think that CO2 levels are not really worth monitoring, you could just ventilate a bedroom, or living room, a bit more. I suspect that we react to humidity and temperature faster than we do CO2 levels (any know how to put a subscript in on an Android phone). As an example, yesterday was 15°C down here. When it was raining, I was shivering, sun out, I felt fine. If CO2 levels are consistently high, there may be other reasons for that, what I am not sure though. -

Is it really worth monitoring CO2? There is such a good correlation between RH and CO2 that it is not really worth the expense and extra complication. It is fairly easy to fit some DHT22s into MVHR ducts, log data and do control from that. A few of use do it already. Like @JSHarris I have collected data for a few years, but the novelty soon wears off. There are things that I would like to automate, basically how long my night storage heaters are on for. But that is more for a technical challenges than for any real and meaningful savings. That trouble with buying stuff that is ready to use. Is that it is expensive. You are paying people to design and test stuff, and offer a warrantee. Then it probably only does half of what you want, and in a format that does not work well with other kit. Take just controlling a motor, it can be done with a voltage or frequency input, any control system bought in needs to be able to handle both of these. 10 quid raspberry pi and a few sensors, a couple if days coding and you are away. -
Land executive, keen to learn more about building
SteamyTea replied to derobe's topic in Introduce Yourself
Are you saying that they get treated differently by LAs, or that they have much larger resources so can explore more 'creative' solutions? I think there may well be a valid point, it may stop self builders wasting time and cash if they know they are going to be treated differently from the start. -
Air filtration is pretty simple really, it is just a matter of slowing the flow rate down until particles stick to something. So the key thing is that you just need a larger surface area. I was on the production side, but the foam manufacturers would tell our design engineers the filtration properties of their materials. I seem to remember that they refereed to it as the Q value, but may be wrong, it was over 20 years ago.

Welcome Quite a few people here have had planning problems, how deeply do you get involved in that side of it, and what creative solutions are there. Re the actual building of houses, most on here are aiming for low energy usage, but take different construction techniques to get there. -
The council has put in some recycled plastic benches nest me. They look alright and don't wobble like the old timber ones.

I am going to buy some bananas and live in a republic. Oh hang on...

Get some reticulated foam, it comes in many 'pore' sizes. It is washable and if bought from the manufacturer/processor, pretty cheap. These are the people we used when making air filters (both small and very large). http://www.foamengineers.co.uk/

If you make something from cast concrete, it does become almost permanent and very costly to change or dispose of. Can't you do something with timber and rammed earth?

Is that the year or the hour?

Raining here, but that is nothing special for August. VID_20190828_120813334.mp4

Why not just get an app for your phone, some bluetooth earbuds and stop annoying everyone else with local radio.

This used to happen in the franchised motor trade a lot. What happens is that say, Vauxhall, gave you a quota that you had to sell, regardless of whether they could supply the cars or not. So what would happen is that at the beginning of the period, there was little discount, at the end of the period, there were huge discounts. Then it was made worse when there was over production and they forced more cars onto the dealers. These were often sold well below cost. The last 2 cars I bought were 'incentive' cars and got 20% of list. So it may be worth Buildhub member getting together and asking for quotes at different times, see if the prices change.
