- Using a neutraliser (I've been told this would work, but I don't understand how!)
I can't use a thermal store because I have nowhere to put one!
Has anyone out there tried to link an open system with a sealed system where different pressures exist? I can't find anyone who's actually done this and I don't really want to spend heaps on something that might not work!
Has anyone got a system like working in the real world?

Thinking out-of-the-box, what in reality would actually happen if all this wonderful talk was put into action?
I for instance (apart from my ongoing discussion on solar water heating) have done everything I can to reduced my electric and gas bills by about three quarters of the norm (just a rough estimate).
Could you imagine how devastating that would be to the government coffers, if every household in Britain were to do the same?
Three quarters of their tax on energy (oil, electricity, and gas) would disappear. And that is only the start.
God forbid that we should get a really efficient bus and rail service that is cheap and affordable that would keep us out of our cars (I travelled on the Belgian rail service last year, and I couldn't believe how clean and efficient it was, even the air conditioner had air freshener incorporated) think of the tax they would lose on fuel, I'm not sure how much tax they charge on fuel nowadays, but I bet it's a massive amount.

“Let Britain lead the way” I wonder why I don't believe them?

Perhaps I'm being cynical. If all the above were to happen, we perhaps, wouldn't be able to afford to go to war quite so often.
Maybe they could go back to the daylight tax

I will let others discuss the merits of alcohol and tobacco taxes (if we tax it high enough people will stop smoking and drinking, do we really live on the same planet?) To name just a few.

That is it I have had my rant for today.

We want to install electric underfloor heating plus a good quality wood floor finish. The decision on electric heating is final. We'd appreciate some advice on insulating the floor, please - this is going to be a d.i.y. job apart from connecting the electrics. Is the kind of thin pad or roll insulation that comes with electric UFH systems good enough to insulate to recommended modern standards, or should we just bite the bullet, take the floorboards up and insulate underneath? There's about a foot of air space beneath the boards and I can guess what the answer's going to be, but we'd really appreciate your opinions.

It has a small wood burner at present on the first floor. The ground floor will have UFH at some point. I am getting gas connected. Question: My plumber reckons the 13 salvaged radiators I have sourced total 41,000 BTUs. He reckons the upper two floors require 70,000 BTUs. The building is approx 10mx10m. About 4 rooms per floor, 3 floors.

This sounds a lot of extra BTUs/radiators. Does it sound about right? Or way off? Any advice very much appreciated.

Instead of the electricity suppliers fostering power meters on consumers and of which they will examine once, then occasionally glance and finally forget, it would seem best for a number of reasons to supply a waste disposal unit under each kitchen sink.

If it is true that the power required to operate a waste disposal unit is less than carting the waste to the tip then it would make sense to feed the 'soup' down the sewerage system, mix it with other degradable matter, filter out solids, semi-dry by centrifuge, compost and finally steam sterilise for garden use.

OK it may require more water - essential to prevent blockage but the water question could be recovered at the distant end. It may cause a blockage of the unit by attempting to process waste which should be recycled, consumers will quickly learn the ropes.

But it will do away with waste which quickly degrades within the household in hot weather and storage problems in households where space precludes an outside bin, reduce the number of garbage disposal trucks on the highway avoiding production of more CO2, reduce or eliminate the disposal of degradable waste in tips and hence reduce the production of methane from buried degradable wate.

Well that's a start, bound to be critics.

The idea that if it is not on the front of a building then that is OK is also a new one and equally dangerous.

How come windmills are OK but not solar panels? And why are homes in national parks penalised -- if it is too ugly there then it is too ugly in my town too.

No planning for conservatories! are they crazy -- these things if heated loose so much heat that they should not be allowed any more on purely energy efficiency grounds never mind carbon saving reasons.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=286 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=286 Mon, 14 May 2007 21:42:00 +0100 philby

I'm planning to make a series of short films whose aim will be to demonstrate practical ways in which individuals and organisations can reduce their emissions of green house gasses. I'm a freelance filmmaker and I'm planning to distribute and publicise the videos on the Internet. At least to start with, I will make the films on my own money. I'm planning to call the series of films "After Carbon" (unless anyone can think of a better name before I start making the films!) I'd like the films to be as detailed and practical as possible (shows like "It's Not Easy Being Green" are great but they are short of practical detail). My plan is to use plenty of diagrams and graphics to illustrate the engineering shown in each film.

What I really need are projects to film! I will do my best to stay out of the way of the work-in-progress and the films shouldn't intrude too much on your privacy - I'm keen to focus mostly on the *installation* rather than on the *installers* or owners! And, of course, I'll send you a copy of the film to "OK" before I publish it. In terms of subject matter, I'd like to cover the broadest possible spectrum of issues - from solar hot water heating systems, to the use of alternatives to concrete, to wood-chip burning CHP systems for office towers etc. In terms of location, I'm based in South East London so the closer the better - I'd say a 3 hour drive is probably the maximum distance I can travel (not least because of the hypocrisy of making a film about limiting CO2 emissions by driving a petrol-powered car around with all my equipment!)

Like many other folk we try to be conscientious about fully turning off appliances that have a standby function when turning in for the night, but the nature of these sort of devices means you're usually crawling under desks, fighting through a tangle of cables, and wondering if you're going to accidentally unplug the alarm clock and have to spend ten minutes resetting it. Our solution was to duplicate the socket circuits, one is generally used for devices with a standby mode and its twin for "normal" devices and those which we don't wish to turn off; the standby circuit has a master switch installed in our bedroom so last thing at night simply flick the switch and 4 TV's, 4 Freeview boxes, 5 PC's, 3 printers, 1 server, 3 DVD's, 2 VCR's, 1 microwave, 3 Hifi systems and numerous other devices are completely shut down. I should mention that we never use the VCR for recording so not a problem that they lose their clock settings overnight, and the DVD recorders are a bit more clever and don't lose their settings, so I'm not a masochist!

It might seem overkill to install extra circuits but the cost was just under £140, yes we have a lot of sockets, and we have little red dots stuck on those on the "standby circuit" to indentify them; but a quick check with a meter showed that we were drawing over 400 watts prior to switching off at night. Even if the circuit is only off for 6 hours each night it equates to about £85 per year, add in a couple of weeks holiday and you're knocking on the door of £100, so the pay back is very short.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=295 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=295 Thu, 17 May 2007 12:39:40 +0100 steve mac My question is do I continue with my plans or do I gently ( 1 metre at a time) remove the mud footings by half the thickness of the 600 mm wall and back fill with concreate .

Mould is forming on the inner walls of a bathroom and a room adjacent a stone walled barn located in southern France. The barn walls are stone and approximate 2.5 feet thick but the bathroom and adjacent room have been formed from a larger room and a section of the outer original wall replaced with a 6 inch concrete block wall and windows. The exterior and interior finish over the concrete blocks is a portland cement screed No DPC was added under the new concrete blocks. Before the changes to the room there was no evidence of mould on the walls or on the adjacent floor

The tiled roof is sound as is the guttering. The terrain is largely sand and drainage should not be problem.

No natural or forced ventilation has been added. The barn living accommodation is occupied for a short time only in the summer, otherwise closed but the door to the rooms mentioned remains open. The absence of mould on the exterior surfaces of the concrete blocks suggest that the natural ventilation of an outer surface prevents mould growth

The problem is growth of mould on the inner cement screeded walls. In addition there is mould on that area of the room floor close to the outer wall. The bathroom floor has been remade with a DPC under a concrete floor and is 2 inches higher than the adjacent room, no mould on the floor but a little behind the loo.

The question is that of treatment.

Ventilation by air bricks would seem to be the first step but would only overcome the presumed higher RH of the two rooms Further ventilation by a fan may be necessary but for 50 weeks the barn is empty and energy expended to reduce mould would be out of proportion to the gain.

If the cement screed was removed from the concrete blocks and replaced with a lime mortar plaster and skimmed with lime mortar/silver sand would that allow the damp in the concrete blocks to be dissipated leaving the plastered surfaces dry enough to avoid mould ? Or would it be necessary to remove the concrete blocks and replace with original stone then face both sides with lime mortar screed ?

If it was just a matter of ventilation what type could reach a satisfactory surface moisture level ?

The studs will be covered with foil backed plasterboard to provide a vapour barrier.

Also wondering what to do at window recesses these have wood panelling which slope towards the window (single glazed sash), not really enough room to insulate on top, but if its worthwhile I could maybe put some of that thin polystyrene backing on (warmcell?) then plasterboard over?

How much cavity should I have? Should I have breather membrane? Should I consider multifoil in the mix (don't hit me)? Are the required U value of 0.2 against the U Value of 0.16 of joist insulation for legitimate reasons or should I be shooting beyond 0.2?
