more than a nursery...

rockenergy's project in Glasgow


We will detail the nursery's key components and technology details in the coming weeks and explain why the construction is "A" rated (EPC)*; here is what our client Milnbank Housing Association and the Energy Saving Trust have to say:

*
EPC (Energy performance Certificate) rated; not rated by any of the rating agencies dominating financial headlines, the rats.

wood is not increasing efficiency!

This is biomass; wood, logs, wood chips, saw dust... no doubt, isn't it? Oh, and it is carbon! Right?

Yesterday I spent the better half of an hour on the phone with a gentleman insisting on his idea of sustainability.

He explained how much more energy efficient his 150 year old stone house had become since he generates the necessary heat by taking advantage of the latest technology from Austria, an automatic log burner.

My question as to how much energy his house would need to be comfortable he answered "Depends on how warm you want it; but a trailer-full a week is plenty. Before the new boiler went in we spent about 6,000 quid a year on oil and electricity for heating."

!?!

Well, I gave the polite and understanding admirer, just as I am told by our marketing and my preferred wife; however, in principle, I am offended: of course, stone-built-traditionalists might admire the strong and secure walls built by stone; fine, I do to, however, I avoid discussing efficiency and energy consumption when I discuss the architecture and construction of these houses; that is a bit like admiring the vintage RR while avoiding to discuss its CO2 performance. What would be the benefit? The difference of the footprints comparing stone built walls and modern high tech wood built frames is massive and positive reciprocal; structural strength and safety are no question at all.

What put me off was his egocentric declaration and use of wood as a cheap and - he insisted on what he has been told for what is probably the last ten years - carbon-neutral fuel. The picture of an enormous trailer a week, probably half a dozen of trees thrown in that burner to be turned to ashes in a fraction of a fraction of the time it took them to collect CO2 and create carbon, i.e. grow over the last 40 or 50 years, is hardly a sustainable one.



The real offence was the fact that he insisted on having turned his beautiful and ancient house into an energy efficient home just by switching from oil and electricity to wood.

I tried to explain that his house's efficiency like that of any construction rather depends on its demand than on what is generating the heat - but only once.

He is an engineer by profession designing roads and bridges. For the sake of my own safety I hope he won't calculate a bridge's load capacity by means of length and height-above-sea-level alone.

postponing and impeding...

Copenhagen certainly is needed but to my mind it is missing the point; tackling "global warming" alone is like trying to get rid of a cough while the heart is under attack.

Like the raindrops fill the oceans it needs pouring thoughts to describe and understand our problem.

There are some elements of our human tradition worthwhile remembering which listening to independent, experienced and potentially wise people is one of. So don't think you waste your time following (possibly a second time) Sir David Attenborough and his Horizon Special on BBC; or click your way through below YouTube feeds.



Remember... "getting bored is postponing but impeding the answer ".

Carpe diem!


"oil" is carbon neutral: or was it "wood"?

People keep repeating that "wood is carbon neutral" slogan to me. Sure, the wood-boiler and other related industries are celebrating this marketing frenzy. But it is brutal rubbish.


Obviously the human brain tends to make calculations neglecting time expecially when the scale of time doesn't match our wee and limited horizon! Watch out, soon we will be told "oil is carbon neutral!" simply because oil = wood = carbon ?!?

Now. how is that?

"What's so neutral about wood? Time!"

Carpe diem!

apropos energy!

telegraph: "Climate targets can't be achieved, say energy companies”

It is very obvious that this statement comes from energy companies that use any type of fossil fuel to generate power. If I was one of those I would most probably sign that statement.

At least, the article says something interesting about gas:


...Several urged governments to consider gas, rather than less reliable, more expensive renewables, because this fossil fuel emits 50pc less carbon dioxide than coal when burnt.

So gas in combination with Combined Heat and Power units (CHPu) and intelligent construction should give us time to develop further energy alternatives avoiding the disasters of idleness and/or fruitless discussions about what should or should not be done.



And what is more Natural Gas could soon become Bio Gas!

What is the hold up?

P.I.C.N.I.C.


Man tries to copy nature; swim like a shark, clean with Lotus or learn from birds' wings how planes can save energy (e.g. winglets). No harm in copying, but why do we only do this half-heartedly?

P.I.C.N.I.C. stands for Produced In Carbon Neutral Integrated Cycle and as such follows nature's rule where nothing is waste but everything is energy. While the manmade definition of waste allows wasting, our globe's logic is to keep things in balance; life incorporates death in form of new life; same as any product recycles to product(s), leaves no room for waste.

Let’s have a party: let's have a P.I.C.N.I.C.!

Un-sustainable efficiency at its Best

These Californian plums are transported and distributed all over the world to be sold as the ne plus ultra of healthy foods, "
voted as one of the best packaged foods for women"; they - the plums - are wrapped individually in foil and come in a transparent foil box for £0.99 -

at Lidls, for example.

What a bargain; if only there was a version for men as well which would make these Californian plums even more efficient - for the Californian manufacturer.

Construction Industry: New Challenges - No!

The challenges have long been addressed; we just need to take action.
It was meant to happen before the credit crunch hit the construction industry so hard; with energy prices going through the roof and the awareness of the vast majority of people(s) that the globe will see severe climate alterations the way we design and build our homes and buildings must change dramatically.

In fact the dominating headline to reduce each individual’s footprint in order to make a real difference emphasises the need to re-think construction, a major player when it comes to CO2 emissions:





It might come as a surprise to some but all the instruments and means to reduce emissions from any building be it residential, commercial, or public by 85% and more are readily available, proven and affordable!

Even a 100% reduction, i.e. no emissions, are possible even though there is a global understanding to talk about “no net emissions” instead; the difference often is described as the transfer from a “Passive House” to an “Active House”.

Those terms and many more like insulation, ventilation, air tightness levels, dew points, condensation and more, but also different heating systems we will blog on in the coming weeks.

All the issues will help to get away from climbing that blue hill in the graph below…

New Thinking!

During a recent talk on the three dominant crises: food, climate and economics one of the points raised was that it will need “new thinking” to make it “Through the Bottleneck”.

Thinking when using our own individual brain’s capacity and methodology might not easily be altered; but thinking definitely needs an upgrade; this download of the latest version of “thinking” must include thinking any issue, subject or object to its end; to think it to completeness, to think integrating all. Previously in the blog I mentioned
lateral thinking as trying to look across the board to perhaps get a glimpse of the future. It is time to finally take responsibility for what we have done and do to our habitat; this indeed requires lateral completely integrated thinking and accepting the outcome by taking the consequences.

While rationality demands
sustainable solutions our thinking must follow exactly that route and by doing so will be forced to leave the beaten track; a throw-away society featuring a purely growth based economy has taken us to where we are; we need to question how we got here not for the purpose of being negative or questioning anybody’s competence; the purpose must be to understand in full the impact, the footprint of anything, any activity, any technology, any product, any decision, just anything. Often “tradition” is made “first priority” followed by “it ought to be preserved”; traditional buildings, traditional technologies, traditional forms of living. Fine, that is good in some places, may be for a museum or to keep an historic setup as an example of our roots; but tradition may not be taken advantage of by trying to protect the “status quo” in order to benefit established but progress hindering, often destructive configurations.

What is tradition? Did Scots traditionally live in thatched cottages, roundhouses or caves? Do we normally eat venison and fish or rather Kentucky’s Chicken and Italian Huts; if every one of these makes the tradition, then why would a highly energy efficient and highly comfortable sustainable future proof building not write the next chapter of tradition?

Traditions made us what we are; thinking always was and is part of us but we remain far behind our capacity; often we hesitate to think beyond the norm as it might reveal a different truth behind something that is taken as a given.

  • To calculate the overall footprint of a Japanese Hybrid car, which is in the mind of many the ultimate solution and “saviour of the Californian climate in persona” might end up as a disaster.
  • To ask “What’s so neutral about wood?” causes panic and raised eyebrows from those who have a hard time trying to get people to think about C and CO2, only.
  • To question the efficiency of a wind generator asking from what point during its life span the 300ft cast-iron pole based in >1,000 tons of concrete will net generate electricity is seen as an anti sanctum.

Questioning the above is necessary to find sustainable answers – taking the consequences will not be any easier.
