We moved here in 2010 and the EPC Certificate had an Energy Efficiency Rating of E48 and an Environmental Impact of E43. At that time we hadn't much of a clue about energy efficiency, airtightedness, solar panels, insulation, etc. We just wanted a house that was large enough to hold my family (me, wife, two kids) and both my parents (in a separate 'granny annexe'). However, when the utility bills started coming in, we soon became experts!! :)

My gut instinct suggests that surely it would be best to collect mixed waste at source in one vehicle and then sort at plant? Surely there must be some research done on this in terms of labour, time, carbon footprint etc? What is best practice? My Local authority doesn't even recycle polystyrene.... My guess is probably something like 40% only ever gets recycled anyway?

Also why isn't more being done to reduce plastics and minimising packaging waste at a higher level? What needs to be done to encourage this?

I know we can choose products with minimal waste but often there isn't a choice. I have seen a local 'zero waste' store pop up but in all honesty the prices are prohibitive and I'd rather just make sure I do my bit to recycle whether or not the Local Authority do this efficiently.

By Michael Le Page

Last week, air pollution in London soared to heights not seen since 2011. The usual suspects were named and shamed, including traffic fumes and a lack of wind. But joining them was a surprising culprit.

“We think about half of the peak was from wood smoke,” says Timothy Baker, part of a team at King’s College London that monitors air pollution.

The trendy log-burning stoves producing much of this pollution are marketed as a source of renewable energy that can cut fuel bills while helping reduce global warming. But recent findings suggest they pose a serious threat to the health of their owners, and are also accelerating climate change in the short term.

If nothing is done to discourage log burning in homes, it could become the biggest source of air pollution in cities like London. In the UK as a whole, wood burning is already officially the single biggest source of an especially nasty form of air pollution.

“I love sitting by a log fire as much as the next person but maybe we need to think again before it’s too late,” says climate scientist Piers Forster of the University of Leeds, UK.

Air pollution is awful for our health. The smallest particles get into our blood and even our brains, increasing the risk of many disorders including heart disease.
Natural killer

Children are especially vulnerable: high pollution levels impair their lung and brain development. Air pollution from all sources is estimated to cause some 10,000 premature deaths a year in London alone, where it frequently exceeds legal limits.

Wood smoke may be natural, but it contains many of the same harmful substances as cigarette smoke. It’s a massive killer worldwide, causing as many as 4 million premature deaths every year through indoor air pollution.

In the UK, however, the problem with pollution from wood fires was thought to have been solved by clean air laws introduced in the 1950s, which banned wood burning in open fires in cities. “The official view is that residential wood burning is a thing of the past,” says Gary Fuller of King’s College London.

Yet logs can still be burned in officially approved stoves in cities. Sales of these stoves have soared in the past decade, rising to nearly 200,000 a year. They are marketed as a way for people to drastically reduce their carbon emissions and save on fuel costs.

Even modern stoves described as “low emission” are highly polluting. And in an echo of the diesel car emissions scandal, measurements during actual use in homes show that the stoves produce more pollution than lab tests suggest.

In the “smokeless” fumes coming from the chimney of a house with a modern “eco-friendly” wood burner, Kåre Press-Kristensen of the Danish Ecological Council has measured 500,000 microscopic particles per cubic centimetre. The same equipment finds fewer than 1000 particles per cm3 in the exhaust fumes of a modern truck. The wood stove was certified as meeting Nordic Swan Ecolabel emission standards, which are stricter than the ones stoves in the UK have to meet.
Big in London

What this means is that a small increase in wood-burning stoves can produce a big increase in pollution. In Copenhagen, a city of 600,000 people, just 16,000 wood stoves produce more PM2.5 pollution – the most dangerous particles, smaller than 2.5 micrometres – during winter than traffic does all year round, says Press-Kristensen.

Wood burning is becoming a big problem in London, too. In 2010, when Fuller analysed particulate pollution to discover its source, he found that 10 per cent of all the city’s wintertime pollution was from wood.

There are many reasons to think that figure is higher now. A 2015 government survey found that domestic wood consumption in the UK was three higher than previous estimates, with 7 per cent of respondents reporting that they burned logs. “Wood consumption is increasing substantially,” says Eddy Mitchell at the University of Leeds, UK.

When he, Forster and others fed the data on wood consumption into a computer model of air pollution, their conclusion was disturbing: PM2.5 pollution from residential stoves is soaring in the UK (see diagram, below).

“There is a real risk that if we have a lot more residential wood burning then it could undo our other efforts to control air pollution,” says Fuller.

The harm far exceeds traffic pollution, he says. While people are exposed to high levels of traffic pollution mainly when travelling on busy streets, wood burning produces huge amounts of pollution where people live, when they are at home.
Indoor smog

Press-Kristensen has been measuring that pollution inside homes in Copenhagen. In three out of seven tests done so far, he has found very high levels. In one home with a modern log-burning stove, he found particulate levels several times higher than the highest ever recorded outdoors there (see diagram, above).

So do the health impacts outweigh any climate benefits? Astonishingly, there might not be any climate benefits, at least in the short term.

Burning logs is often touted as being carbon-neutral. The idea is that trees soak up as much carbon dioxide when growing as they release when burned.

In fact, numerous studies show that wood burning is not carbon-neutral, and can sometimes be worse than burning coal. There are emissions from transport and processing. Logs are often pre-dried in kilns, for instance.

Burning wood also emits black carbon – soot – that warms the atmosphere during the short time it remains in the air. Most studies ignore this, but Mitchell and Forster calculate that over 20 years – the timescale that matters if we don’t want the world to go too far above 2°C of warming – soot cancels out half the carbon benefits of all wood burning.

For home wood burning, the figures are even worse. “On a 20-year timescale, wood stoves provide little or no benefit, but they do on the 100-year timescale as they remove some of the long-term warming effect of CO2 emissions,” says Forster.

Press-Kristensen’s calculations show much the same thing. And both sets of findings almost certainly underestimate the problem, because they assume wood burning is carbon-neutral.

Defenders of wood stoves point out that there is a lot of uncertainty about how much black carbon is emitted when wood is burned and how large its effect is. Patricia Thornley of the University of Manchester, UK, thinks we need more real-world measurements before coming to conclusions.

But the uncertainties cut both ways. For instance, the effects of black carbon can be amplified if it is deposited on snow and melts it, exposing dark land that absorbs more heat. It’s possible soot from wood burning is contributing to the fall in spring snow cover in Europe, but it’s very hard to study.

More research is needed to pin down the precise climatic effects of wood burning, which can vary hugely depending on factors such as the source of wood and where the pollution goes. What is clear, however, is that burning logs in homes in towns and cities is not the best use of the wood we have.

It produces more pollution than wood-burning power plants that can be fitted with expensive filters, it produces that harmful pollution where lots of people live, and it has the least climate benefits, if any. “If we are going to burn biomass to meet climate targets, then we ought to do it in big, remote power stations,” says Martin Williams of King’s College London, who is studying the health impacts of the ways the UK could meet its climate targets.

Most researchers say it isn’t their role to make policy recommendations, but it would be best if cities like London discourage private wood burning before it becomes an even bigger health problem. At the moment, all the focus is on diesel vehicles.

Press-Kristensen doubts governments will ban wood-burning; France recently backtracked on a proposed ban on open fires, for example. Instead, he proposes installing heat sensors in chimneys and taxing people when they burn wood, with the level of tax depending on how polluting the appliance is.

Most importantly, governments must not ignore health impacts when deciding climate policies, says Press-Kristensen. “I like fires, but I have to say they are as polluting as hell,” he says.

Thinking of getting a wood-burner?

Wood-burning stoves are touted as an eco-friendly way to heat your house cheaply. But tests now show that even new, properly installed stoves can produce dangerous levels of outdoor and indoor pollution (see main story). What other options are there?

Consider instead
Stick with gas or oil for heating, and spend your money on insulation. Get a heat pump if you can afford it

Fake it
You can get the same cosy feeling from a log-effect electric or gas fireplace, the best of which are hard to distinguish from the real thing
Already have a wood-burner?

Here’s how to minimise its effects:
Don't burn scrap wood
Scrap wood or painted wood can release highly toxic substances such as arsenic when burned

Burn wood that's just right
Burning dry wood with a moisture content of about 20 per cent minimises pollution. But if wood is wetter or drier than that, pollution increases]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417 Sat, 23 Aug 2008 07:43:51 +0100 j40
Until recently I didn't even know these sun tube / pipes / tunnel even existed. They are an excellent innovative idea but actually very simple. Sorry- I should explain- essentially a system which, through a highly refelctive tube, brings natural light from your roof (by way of a sky window or dome) into your dark rooms - normally first floor- or ground floor on bungolow (but i have also heard that it can be brought down to ground floor in a two storey house).Apparently it can be installed in basements through the wall- like a porthole!

Anyhow, I was just wondering how many people are amazed that these natural light sun tubes / pipes are not more widely known about?

so we now live in our straw bale home and have a wood burning range which does all our cooking, heating and hot water in the winter. Come the summer our cooking options are much reduced in the house; no alternative to wood. Do use a rocket stove outside and probably will do a solar oven, but I would like to have an iven inside. Please would someone advise me about most energy efficient option for retro fitting into kitchen?
I've looked at steam ovens briefly and wonder if they can easily be retrofitted. Don't have an obvious place/vent to outside, so the simpler the better. I dislike microwaves passionately.
Do steam ovens need a place for heat/water to go? Do they make food kind of wet, steamed rather than roasted?

I said to the receptionist, "there is no way that I am taking the lift please direct me towards the stairs".

They replied, "the stairs cannot be used as they are inside a secutre zone".

I dug my heels in and insisted that I would not be going up in the lift.

Eventually I was escorted up the stairs, it was hard work and I felt like I was being awkward.

So we decided we need a slow cooker.

But I am a bit disappointed to see how poorly insulated most of them are. Reviews regularly talk about people burning themselves on them. I don't know if I can bring myself to buy something so inefficient.

I remember Blue Peter back in my youth demonstrating how to slow cook without power by placing your casserole dish in a cardboard box full of straw... or was that how to hibernate your tortoise? Maybe I am getting them mixed up.

Anyway, it seems to me that if you put 150W into a slow cooker and eg. 100 watts is leaking out as heat this is not a very efficient way to cook. And they all seem to just have two settings (high and low) with no indication of just how much heat they put into your food... no temperature gauges. How are you supposed to know how long is long enough? Why aren't they better insulated? Why aren't they better instrumented? Why can't I find a slow cooker targetted at people like us? Is there such a thing?

Also considering vs just cooking in a casserole dish in the regular oven at 100C. That surely wouldn't leak as much heat into the room?

I searched these forums for slow cooker first but didn't find anything so thought it worth asking.

I did find a navitron thread

Sadly in the new house I was seduced by fashion - so many sinks only come with one tap hole - and ended up with a monoblock tap in the bathroom. There was also the suggestion that it would be nice to mix our new and consistently hot DHW to the warmth of choice out the tap. Immediately I notice we are using more water, you can't easily nudge it on and off so despite wanting to interrupt the flow I end up leaving it running. There is also the need to run off any hot water left in the neck when you want cold and vica versa, more wasted water and all those little amounts add up. As for blending water temp I am habituated to washing my hands in cold water anyway (after years of a boiler that took 5mins to supply hot water).

I am left wondering how much water we could save as a nation if the monoblock mixer tap was banned? Apart from the cost of embodied energy, and the changes to the countertop, I am seriously considering replacing both sink and tap with a two tap version.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12245 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12245 Mon, 23 Jun 2014 17:35:21 +0100 Gotanewlife several 1m3 water containers giving a minimum 1m head but their veg patch and sitting out area are growing exponentially!! For the irrigation system I have fitted 40mm main lines and individual taps off into 16mm pipe with pairs of pre-made leak holes every 350mm, ie no sprays, but some of the runs are quite long now and there are an every growing number of runs.

Any thoughts gratefully received.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12144 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12144 Thu, 29 May 2014 17:39:29 +0100 tony
‘Reading Sustainability Centre’ have just embarked on an ambitious project which will produce hydroelectricity from the Thames. They plan to use the power and income generated to help run a Sustainability Centre located near to Caversham weir. The group is in the process of setting up a Community Interest Company, a not for profit organisation that will enable it to raise the funds needed to complete the hydro project.
Initial feasibility studies have been very favourable, and such a scheme with an associated sustainability centre would be very good for Reading, both for local residents who will benefit and in terms of external interest generated. ‘Reading Sustainability Centre’ is working closely with existing environmental groups in Reading, and local experts such as Oxford Low Carbon Hub and e-waterpower. They are an apolitical organisation and as such, are keen to have input from everyone.
There will be a site visit and picnic on Wednesday 4th June and to which all are welcome. Please meet at the footway near Caversham Weir at 5pm. After examining the Weir, Lock Island and View Island there will be a bring and share picnic at 6pm.

See our newly created website which will be improved all the time www.ReadingSustainabilityCentre.co.uk]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12104 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12104 Sun, 18 May 2014 23:04:38 +0100 caspen
Do you know if we could use it to run an additional freezer? The freezer would be turning off whenever there was no electricity generated. But if we didn't open the freezer when it was off, eg in the evenings and at night, would the food inside be OK until the freezer turned on in the next generating cycle. It's likely to be the excess fruit and veg from the garden.

Many thanks for your experience / knowledge.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12116 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12116 Thu, 22 May 2014 09:08:02 +0100 jamesingram http://www.theguardian.com/environment/2014/may/18/bird-killing-call-robin-starling-mallard-splits-conservationists
Sounds rather strange?
For a alternative viewhttp://tompride.wordpress.com/2014/05/18/heres-the-real-reason-the-tories-are-allowing-the-destruction-of-robin-eggs-and-nests/
"There is no explanation of what exactly the public health and safety hazards of robins’ and starlings’ eggs are.

However, after a little investigation into the murky waters of party donations all has now become clear.

Last year government ministers chose Andrew Sells – a Chartered accountant with no experience of ecological or environmental matters – as the new Chair of Natural England.

Sells is a venture capitalist and a major Tory party donor – in 2011 for example he donated £111,250 to the Tories.

OK, so far so corrupt. But why would the Tories want to allow the destruction of robins, starlings, wagtails and other such beautiful birds?

Well, Sells is one of the founders of Linden Homes, a property development business specialising in developing brownfield sites for residential housing.

And what is one of the biggest problems facing property developers when they attempt to develop brownfield sites for residential housing?

Yes, you’ve guessed it – nesting birds"]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12021 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12021 Fri, 25 Apr 2014 15:04:01 +0100 Triassic

An interesting read..]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11417 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11417 Sat, 16 Nov 2013 17:08:46 +0000 ag I am considering the option of installing a composting toilet in my cabin and would welcome advice and guidance.
Having researched various options available to purchase I am considering a system which separates liquid waste and solid material and using airflow through venting allows breakdown of both liquid and solid materials. As an adaption to the system I am considering using a vacuum toilet usually used in boats to allow me to situate the composting system in an area of my choosing which will allow more sunlight onto the collection unit to make it more efficient, though I need to investigate if this would work when combined with the composting system.
As this is the first time I have installed such a system I would appreciate any advice regarding composting toilets and their installation and if it is possible to build a system myself ( I ask this question as I have viewed some very informative videos online)
Thanks Andrew.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11416 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11416 Sat, 16 Nov 2013 16:52:11 +0000 ag
I am in the initial stages of researching if it would be possible to filter and harvest rainwater for use in my cabin. I would like, ideally, to be able to filter collected rainwater to be used instead of mains water for drinking water(if possible) etc. If this is not possible then only for use to flush a single toilet.
I have found some information regarding manufactured complete systems but also alot of home made systems using electric pumps and also ram pumps.
If anyone has any advice or has fitted a system your advice would be greatly appreciated.

Thanks Andrew.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11134 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11134 Fri, 13 Sep 2013 11:23:04 +0100 Jamster

Perhaps we should all shower with a friend. Makes a change from being asked to bathe with a friend :-)

Firstly, this show is also on today as well as yesterday, so there is still time to go.

I spent a morning yesterday visiting a number of stands. I didn't bother with the presentations as I wanted tailored information.

I was particularly interested in the Green Deal Assessment as it will probably apply for the RHI (if that ever sees the light of day!). Information from various people suggested that an announcement was imminent.

I asked various companies about battery backup systems for storing electricity generated during the day and using that overnight. Still a costly technology but worth putting your name down to be kept informed of developments.

Perhaps the most interesting time was at the stand of Western Power Distribution. I was after any Cornwall electricity usage stats (unfortunately not available as the companies are concerned with the instantaneous power demand and that the supply is over a region rather than the County boundary.

The discussion then turned to their various research projects, which are funded out of a pot from the various energy companies and the results disseminated amongst those companies. Not surprisingly there is a lot of research, inter alia, into the effects of distributed generation, voltage levels and the possibility of dropping the voltage down by 6 volts or so, and the effects of e.g. heat pumps. Whilst WPD didn't say anything about grid capacity in Cornwall, other companies did comment that capacity is probably being reached and that technique and policies for encouraging local consumption of locally generated supply are going to be needed fairly soon. Mention was made by one company (I've forgotten which) that Germany is introducing a tarrif to encourage usage of locally generated supply.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10728 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10728 Thu, 30 May 2013 15:56:58 +0100 SteamyTea http://www.bbc.co.uk/programmes/b01snbm2

Second; Is the increasing useage of huge glazed areas in out homes very bad, not only from an insulation point of view, but also from a wildlife perspective?
Third; Bit of a daft question, but are there any non reflective sealed units?
