It looks as though it is a PIR activated controller for switching off appliances, particularly entertainment devices in the living room.

Anyone got one or seen one at any of the shows?

Not expensive and gives a claimed 2 year payback. My only concerns are:

1. As PIR controllers are movement activated, will they turn everything off if you just sit on the sofa and don't move for 5-10 minutes?
2. The worst power user on standby is a Sky box. Our HD Plus box uses 15.5 Watts average on auto standby (really Sky, get your act together!), 21 Watts in use. Powering this unit down means no recording is available and you have to wait for it to reboot before anything can be watched. So it cannot really be connected, an opportunity for £20 per year in savings missed.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10391 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10391 Mon, 25 Mar 2013 13:05:02 +0000 dazdread
Transition Town Market Harborough is part of a successful bid to run a sustainability project here in Market Harborough over the next five years... can't tell you the name as it is a secret for now :o)

We are working with a local housing association to create a demonstration retro-fit home, now obviously we would ideally like to have a solid walled, single glazed dwelling to show the dramatic savings that can be made but the only home we have available to us is a 1950's cavity wall (Filled) home with C-rated double glazed windows and 250mm of loft insulation (Presumably rockwool) and it has an A-rated boiler. The house is certified band C on its EPC.

So the reality is that this home is probably where many private homes are and there are no real cost effective infrastructure upgrades that can be made. We have decided to proceed with this home and the concrete ground floor has been dug out and replaced with an insulated slab and inter floor insulating installed (Aided by the fact the ceiling fell down).

The question here is can significant savings be made by technology and services as well as behavioral changes if so can we have your ideas and hopefully they will create an easily replicable package for other homes.

We have decided to provide this home to the tenants with the white goods in place so as not to compromise the project with old, energy inefficient goods.

Can you recommend anything that we should consider... with a limited budget.

Best regards

150l or 120l or 100l or 80l or less?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9777 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9777 Sun, 04 Nov 2012 09:20:11 +0000 GaryB 2 kWh per DAY. This is equivalent to 750 kWh pa, costing me £115 a year.

I insulated the freezer sides and top (it had a condenser coil at the back) but it didn't make a noticeable difference. No longer requiring the capacity of freezer (due to empty nest syndrome), I ordered a frost free fridge freezer rated at 226kWh pa.

This new unit has been running for just over a week and the plug-in meter indicates it used just 1.74 kWh over a week.

The energy consumption equates to just 90 kWh pa, much lower than the 226 kWh pa official rating. This performance is I believe down to the following:

The fridge freezer is in an unheated utility room (10 deg C to 15.5 deg C range) giving less heat gain, but because it is primarily a fridge, the official rating must include for frequent opening and closing of the door, which doesn't happen as it is used as an overflow for our Bosch larder fridge (113 kWh pa).

The fridge freezer cost just £219.00 including home delivery. This gives a payback of 2 years and will save 650 kWh pa of leccy.

I recommend checking of your existing equipment using a plug-in meter and also reduce the amount of times the fridge door is opened and closed, as this seems to have quite an impact on consumption.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9177 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9177 Thu, 07 Jun 2012 16:30:23 +0100 tony

Also at the other end of the scale: Who is already using heating?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2719 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2719 Sun, 12 Oct 2008 13:50:24 +0100 TheDoctor
The majority of winter heat will be off a central wood-burning stove, to minimise the use of the LPG, but i am interested in the most efficient difference between daytime and nighttime temps.

The system comes pre-programmed to 21 degrees day and 17 degrees night.
That's way too hot for me!

I was planning on a daytime temp of 18 degrees (which would then be tripped off as the woodburning stove would exceed this when it is running. What about night time?

17 is 4 degrees lower than 21 - should i set nighttime at 14 degrees?

i'd love to have it off, but apparently it is most efficient to keep a constant to reduce wasted energy bringing it back to temp.

thoughts would be welcomed!]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2756 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2756 Fri, 17 Oct 2008 23:58:54 +0100 Bruce Davis http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2032 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2032 Mon, 30 Jun 2008 17:09:13 +0100 SimonH
I currently drive an old BMW 330Ci and want to switch to something lower polluting. However I have realised that selling it won’t get rid of it’s emissions. In fact they could make it worse – depending on who has the car next (I drive it very slowly!). After looking at hydrogen or electric conversions I have realised they’re not economically viable (or even available) and went back and had a look at LPG – something I discounted previously as I only do about 7,000 miles per year.

Now I’ve done some calcs and found that LPG is not only cost effective but also very low emissions. In fact so low, it makes me wonder why we have diesel/petrol?

I found for my 7,000 miles per year the 330ci with an LPG conversion will have:

Emissions of a Ford Focus Econetic Hatch (1882kg 330ci vs 1860kg Econetic)
Fuel Costs of a VW Polo Bluemotion (£745 330ci vs £764 Bluemotion)

As a comparison the Toyota Prius came in at 1,557 kg and £805.
The 330ci currently on unleaded petrol is 2,324 kg and £1202 yikes! In fact its worse as it drinks super unleaded – same emissions as unleaded but about £1.20 / litre.

These are based on real world consumption figures – mine for the 330ci and www.spritmonitor.de for the two “Eco cars” from Ford and VW. I guessed these will be better than average figures as anyone bothered enough to post their fuel figures will probably drive sensibly.

Here’s my conversion figures if anyone wants to check. Is this too good to be true!? Instead of shelling out -£4-5k to “upgrade” to a low emission car, I can just spend £1,800 on an LPG conversion. And I’ll know that when I do come to sell the car on – at least it will do less damage.

Litres -> Gallon 4.54609188

Petrol Diesel LPG
£/Litre £1.19 £1.25 £0.59
£/Gal £5.41 £5.68 £2.68
kg CO2/L 2.3 2.63 1.49
kg CO2/G 10.46 11.96 6.77

Focus Econetic 45 mpg.
Polo Bluemotion 52 mpg.
Toyota Prius 47 mpg.
BMW 330Ci 31.5 mpg (currently with unleaded) 20% less for LPG = 25.2 Mpg.
(all well below manufacturers claimed figures except for mine)

Get your mileage and divide and times the above figures a bit by fuel type/mpg to see how you’d come out.

One thing it shows, that MPG isn’t the best thing to go on. Diesel gets more MPG but costs more and has higher CO2 per litre. Plus a whole load of other nasties.

The thing that swings it for LPG is the very low 1.49 kg/CO2 per litre – I think because there’s more Hydrogen than Carbon in the propane (C3H8) / butane (C4H10) mixture and than you get with the complicated unleaded : C7H16 C8H18 C6H12 C5H10 C6H6 C7H8 & C2H5OH C4H9OCH3 etc. Even though the energy density is lower it’s more than enough to make it the lowest emission fuel.

And the lack of TAX – which I can now see is more than justified based on the [lack of] emissions.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2564 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2564 Wed, 17 Sep 2008 14:53:13 +0100 JackyR

- Distance between greywater/reedbed and the well is about 240 meters
- Well will be about 70m deep
- All of the land slopes gently towards the well

There's nothing we can do about the location of the well, but the location of the greywater/reedbed is still to be decided, unfortunately no matter where we put it, it will be upstream from the well.

However they use a lot of concrete. But, maybe you can justify using this amount of concrete if the building saves so much more Co2 over it's lifetime because of it's efficiency? Over the longer term this may be more beneficial.

We are in the thrall of a cat. Since Friday he's not eating Whiskas beef flavour (this week - 2 weeks ago he wouldn't touch rabbit). For want of a hedgepig (I've seen less road kill this year so I think their numbers are down) I gave the cat's rejected supper to the tadpoles. I've been offering a vegetarian option (lettuce) for 2 weeks but it was something like a shark feeding frenzy when they got their mouth parts round the Whiskas. They evidently enjoy it.

Question : is this a good idea? I'm not worried about them turning into cats rather than frogs or anything (and I can see that every scrap is eaten up so it doesn't pollute the water) - but is it likely to make them diabetic or give them kidney failure (or whatever).

We lived in Sweden is the 1980s, in a house only some 10 years old at the time, and there they had an entirely different approach to double glaze. The window simply had a double casement, each single glazed, but one which opened outwards and one that opened inwards. It worked a treat. We were never cold (even at -25C outside) and the windows rarely fogged up – and even if they did, it was a simple matter to open the inner pane and wipe the glass. The rubber insulation round the windows was also of better quality than I’ve ever seen over here in the UK.

These days sealed units are much more common in Scandinavia but two weeks ago we stayed in a brand new hotel in Norway, which has a similar solution to double glaze to our house in Sweden. Only this time the window opened outwards only and with the inner and outer casement being hinged together.

We are thinking this would make a much better long term alternative to our sealed units here. Does anyone know of a supplier in the UK?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2112 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2112 Thu, 10 Jul 2008 10:37:56 +0100 jules
My theory is that I should aim for as slow a burn as possible, presumably by restricting air supply. The idea is that this would minimise the amount of carbon that disappears as CO2, and maximise the amount of ash/charred wood remaining, which would presumably be good for the garden or compost heap (which is probably too nitrogen-rich anyway). Am I right? We normally discuss maximising the efficiency of combustion here, but I guess I'm after the opposite, if my theory is correct.
