Carbon Neutral

This isn’t meant to be too serious or a downer or a go at any one.

being carbon neutral or carbon positive (is that a term) doesn’t have to be that hard. There’s a massive amount of opportunity in this sector and who knows if some bright sparks came up with some clever technology ideas I’m sure a few start ups could emerge from the space.

It breaks down into lower your foot print, use renewable energy, maximize efficiencies, off set.

There’s a lot we could do in the space to lower our own footprint. Which would be a start.

We could also pay some of our surplus to off set our carbon use. Probably our only option as we don’t have much potential to create much renewable energy on (this) site.

Examples of where we fall short at the moment are:

Monitors and PCs could be set to go into hybernation monitors set to turn off automatically. Currently, often, pcs and monitors left on permanently.

Printer constantly on stand by. There must be a way to improve that.

Using recycled consumables. Maybe printer paper is our only choice here. I don’t think we are currently buying unbleached recycled paper. We probably should be.

We could do something clever with the lighting like they do in some supermarkets to go threw phases of brightness or xyz.

Improve the insulation and heating in the space. Think that’s on the to do list.
Adversely I’ve heard a few people comment on how nice and cool it is in the space in the summer on baking hot days.

We have just got a contract with an excellent local recycling firm. Check there website out. It’s really good and lowers our footprint. It being a local firm is already a big carbon saving and they are doing (or will be when we start using them more) great work turning our food waste into compost, that they send to local farms.

We could source and start using / recommending a good local wood source. Opportunities for bridge building with other local businesses.

Encourage the use of reclaimed materials. I think a lot of members are already doing this on projects as it helps with cost.

A lot of the equipment in the space is 2nd hand which is brilliant as it has zero carbon footprint for us in terms of its manufacture.

Are there opportunities to work on local projects to raise awareness and problem solve.

Having our open evening in collaboration with “Restart” (?) was awesome. Empowering local people to fix there own stuff instead of throughing it in land was great. Let’s do another.

I think we’re already doing a lot. And a lot of members think about this stuff already. I hope we can do even more. And I hope it’s seen as a great opportunity for applying our vast skills and knowledge, and having some great opportunities for problem solving.

2am rant over.

I’m sure I missed a lot of stuff out. What do other people think?

I think you’re bang on the money.

We have insulated fairly well. Heat recovery is on the cards: we will lose a lot of heat through ventilation – though this isn’t currently working, almost begging the question of how much is needed…

I don’t like too much bureaucracy, but having a WiKi for sustainable practices and consumables would make it easy for us to comply.

I keep wondering about solar panels for the Bath Factory Estate…shame about the trains on the roof.

i keep thinking about solar panels too!

im sure theres a great project we could tap into here.
Use the SLMS Hive Mind to create something practical and useful.

I’m starting to run ‘make your own solar panel workshops’…so we could DIY panels to fit any space we need to populate.

We are West facing, and see heavier use in the afternoon/evening, so solar wouldn’t be crazy, if we could arrange a sensible mounting scheme

(Or ask nicely and put something on the roof of jelly tots)

Getting a local business interested has crossed my mind…

Is that with Demand Energy Equality? I’d love to know how it goes.

ild love to find out more about what you are doing!

what do people think about us setting up a DD to off set some carbon or maybe just give money to a wildlife charity and / or a local start up that is involved in something green

We need to measure our impact first. Also: always better to treat it at the source than to buy our way out.

I’m not sure our finances are so flexible right now that this is the best idea (financially for the company - I’m in general pro offsetting)

Yes. I did a training weekend with them back in November and I’m shadowing a workshop Sunday.

How efficient are the diy jobbies?

Same PV cells in essence. Customisablility is a major strength.

I’m on for playing with Solar (Ive got a few low power solar projects running already)

We’re currently looking at Green suppliers for home which offer a good % of renewable, this is our best bet for lowering our electrical carbon usage overall.

I think solar would be more of a fun academic project than a green one as for powering the arch…

For solar, a standard solar panel has an input rate of around 1000 Watts per square meter in bright sun, however on the solar panels available at present you will only gain roughly 15-20% efficiency at best. Therefore if your solar panel was 1 square meter in size, then it would likely only produce around 150-200W in good sunlight while facing South/South West etc etc, inverters take a chunk out of that too so 1 meter of panels in bright sunlight would just about offset the arch lighting at midday. we would then need an feed in meter and a new power contract and ti use commercial parts only (no hand made bits).

So to get a decent system of say ~4kw/h we would need 20m2 of panels that are South-South west facing (~210ft2 in old money)

On this level, we’re already doing well, our supplier is supplying us with 95% renewable electrons :slight_smile:

agreed. absolutely.
but i guess “best” solutions aren’t always achievable in the short term or long term.
ild see offsetting as a quick fix that could be improved on.

Panels are £1/W these days, so £4k for panels, £1k for an inverter and probably another £1k on top for supports, cables, meter, installation etc.

A similar system cost me £9k (installed by professionals) on my roof at home, 5 years ago.

I get a good Feed In Tariff so this system will pay itself off in another 3-4 years. That subsidy is now much reduced (and is tied to the property, not the organisation), so the payback period would be very long indeed. Far better to buy renewable electricity from the big boys IMO.

First mile is already a local recycling company, 0 to landfill, they recycle everything or use it to make electricity. They don’t ship it anywhere it’s handled locally.

Yeah. If we DIY it would need to be an off-grid bit of electricity – for a specific use. Which is feasible?
