Also an analysis of the relative costs (financial and environmental) of electricity vs gas as the fallback for heat and DHW for this system would be useful - if anybody can point me to one.

So as I am getting the house rewired, I need to start thinking about lighting. For most rooms it is a simlpe case of puting normal energy saving light bulbs in. But what should I do in the Bathroom?

Halogen is better than normal lightbulbs but not as effecient as energy savers, LED looks promising but a lot of LED stuff does not allow you to replace the bulb, I have also heard talk of the need for an LED control box?

Any advice experience or suggestions in this area would be greatfully appreciated?]]>

But someone has suggested that I use a steel frame to "stabilise" the straw bales

I'm not sure they need stabilising but if they did would a steel frame have any advantages?

The idea (as I understand it) is to put up 4 legs outside the walls - stick a metal roof on top & go from there..........is that a good idea?

I have a feeling it will cost more]]>

i am *considering* sheeps wool insulation for a coffee shop refurb. i'm less interested in its thermal properties but more interested in acoustic performance. i need 100mm batts for a false ceiling between floors (35 sqm) and partition walls (10sq m).
has anyone got any experience of its effectiveness in this kind of application?
... also would its moisture retention properties help improve the climate in the building?

at a good deal more than twice the price of say acoustic rockwool i'm struggling to justify the expense.

are there any other environmentally friendly alternatives i may not have considered?]]>
PVs on construction sites http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=143 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=143 Tue, 27 Mar 2007 09:46:51 +0100 annabel
Paticular areas that I am concerned about include: increased maintenance costs due to dust from construction site, the fragility of PV modules, how much shading is likely to reduce efficiency, whether planning permission is required, and of course the payback periods for both money and carbon emissions from manufacturing (I have heard extremely varied figures regarding this last point).

Any comments would be appreciated, thanks.]]>
Solar heating; cylinder help needed, Urgent http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=104 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=104 Wed, 14 Mar 2007 21:25:29 +0000 William I have opted for a condensing gas boiler, with a seperate unvented cylinder to run my hot water and underfloor heating. I want to add solar water heating in the future.
I am told I need a twin coil tank ( one coil for future solar) and that the solar connection will be made to the top coil. Is this right?
I was on a manufacturer's web site which shows the solar coil as being the bottom of the two coils.
Which is correct?]]>

Chipping off the render and starting again is not an option unfortunately. So we are considering other ways to rectify the situation. We’ve heard about a microporous product called Andura (used by many companies that advertise render repair and restoration) and Beeck’s silicate paints.

Can anyone advise us or share their experience? The walls are 65cm thick stone/rubble fill so inserting aeration bricks may not be possible.

Verges and undercloaks http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=128 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=128 Fri, 23 Mar 2007 11:29:16 +0000 Julian Timber frame extension, roof trusses at 600 centres, reclaimed concrete double roman 50's, breather membrane.
1. I want to use cloaked verge tiles - it seems sensible to avoid wet verges. But I don't see that many cloaked verges and wondered why? Anyone have any views on them?

2.If I do use cloaked verge tiles could I use 150mm strips of WBP as an undercloak instead of the asbestos/cement type? I would guess there maybe less condesation risk from a piece of WBP than from a cement/asbestos undercloak.

3. Plastic eaves protectors & plastic felt supports - is there an alternative or are they essential? All the plastic fittings are expensive. The existing roof has bitumen felt down over the fascia board - it's been there for years without miles of plastic and without any obvious deterioration.

Opportunity to help build an earthship in France http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=130 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=130 Sat, 24 Mar 2007 18:10:29 +0000 earthship
Introduction
Since visiting Taos, New Mexico in October 2005, my involvement in the whole earthship concept has grown. In July 2006 I became a Director of Earthship Biotecture Europe and in November 2006 Europe's First Planning Approval for an Earthship Dwelling, was achieved.

This spring Earthship Biotecture are offering opportunities to work alongside the the Earthship Commando Crew constructing the first residential Earthship in Europe to receive a building permit. The Earthship Commando Crew, led by Michael Reynolds, is based at our world headquarters in Taos, New Mexico. We are currently interviewing for positions in the program. We will be accepting 6 people per week for the duration of the 6 week long build. Fees for the program are $300 per week. Those accepted in to the program may sign up for as many of the six weeks as they choose. Participants are responsible for their own accommodation and food.For more information email Kirsten Jacobsen kirsten@earthship.org

The plan for the story is to get each one to look around at the existing and new green building organisations and decide which one, if any would best suit their goals or needs. The contributors would also, hopefully compare what the green building organisations appropriate to them may be offering that exceeds, compliments (or not) the more long term established trade organisations that they may already be members of.

We want to present our readers with a broad picture of what is availabe, at what cost and what benefit. We may follow it up in the following issue with a layman's wiew of it all.

Apologies to Biff for any spelling errors.

Post feedback here on the idea or contact me direct if you want to get involved.

Would straw bales be a cost effective way of insulationg my walls

Can I put them outside the concrete block walls (to save space)

How do I finish them off? Render?

How do I do the edges for windows/doors/roof?

Or are straw bales expensive?]]>

Is this a practical option - does it provide electricity? How would I use that to heat the nursery?

Would it need filling like a car engine or would it be attached (like an LPG tank)?

I dont want a glazed roof due to poor performance in summer and winter.
I would prefer a solid thermally insulated roof but just been thinking another option may be solar glazing with an embedded pv array.

I know it will be expensive but just wanted to know if anyone had actually used any and how expensive it is and would it provide any thermal insulation in the winter.

Salisbury Walled Garden http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=66 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=66 Sat, 24 Feb 2007 19:25:10 +0000 biffvernon
***THIS IS AN URGENT CALL OUT FOR ACTION!!***

300+ YEAR OLD WALLED GARDEN AND 15 TREES ABOUT TO BE DESTROYED ANY DAY NOW IN SALISBURY!!

In Salisbury this week, trees are about to be felled any day now to make way for the new Council Offices development and ridiculous glass office extension, that will not only be costly to built but very bad for the environment and CO2 levels. This will destroy forever a WALLED GARDEN THAT’S MORE THAN 300YEARS OLD, with two 18th Century walls, many beautiful big trees aging from 50-150 years, and inside the garden is a Victorian fountain at the centre of SALISBURYS ONLY PUBLIC POND!!

Tree’s to be felled include: Hornbeam, huge triple trunked tree, estimated 80years but grown up from an even older stump that’s possibly 150 years old. Also home to soon to be nesting bats. Sweet Chestnut, huge, about 70years old, Goats Willow, Pussy Willow, Sycamores, Hawthorn, 3 Yew trees, 3Apple trees, A Pear tree, Prunus and a Wellingtonia. There are also two other Hornbeams, one already cut down to a stump and the other half felled. Also an Oak and an Atlas Cedar / Cedar Atlantian will alledgedly be “saved”, but we cant see that they will remain unscathed as they are right in the centre of what will be the main works access to the soon-to-be building site.

The project seemed to be on hold, but now they are pushing ahead to fell the tree’s JUST IN CASE the development project goes ahead. It’s a great shame, as this garden is very old, more than 300 years and has fondly been known to Salisbury’s children as “The Secret Garden” for generations untold.

Please please come and help if you can, apparently they may have to cut down the remaining Hornbeam before next Thursday as that’s the DEFRA deadline as after that the bats will start nesting, so it may not even take that long. There are only 2-3 of us here, we desperately need more numbers- however many for however long/ short could really mean the difference of success/ failure. They were clearing bushes today and will fell the trees any day now or next week.

The concrete blocks will need rendering so the idea is to insulate externally and then render

So far my options appear to be
Straw bales (no idea of cost)
Herakith boards (£67K?? - I must have it wrong:cry:)
Difflum boards (even more expensive)

Are they more conventional methods?

PS really don't have a clue do I?]]>

New tech insulation v's older materials http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=25 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=25 Mon, 05 Feb 2007 10:13:22 +0000 Tuna
Some of the claimed benefits of hemcrete focussed on insulation. Thermal scan images of two identical homes, one built with traditional materials, the other with hemcrete, showed the traditional home leaking heat. The explanation seemed to be that around openings and between floors, the traditional insulation materials tended to leave gaps or sag. Air gaps also encouraged dampness and so thermal bridging. The argument for hemcrete was that, as a rigid packing material it performed significantly better than traditional materials, even at thicknesses that performed averagely in hot box tests.

Sound familiar?

I wonder if the real world benefits of some of the 'newer' insulation materials are simply based upon the fact that they can be installed as a larger continuous surface that resists sagging and thermal bridging due to dampness? Are our traditional builds actually under-performing by some significant margin, allowing 'marginal' new technologies to match their in-situ results? Should our hot box test involve a hot box that more closely resembles an entire room - with all the detailing and openings and other real world issues?]]>
