CIBSE and EPC’s

January 13, 2008

Yay, CIBSE members (with qualifications) can do EPC’s. How many existing buildings are there out there that need EPC’s. A lot. A largish commercial building will cost about £2000 -£3000 a pop. Imagine if you are a university or council…….that’s a lot of money you have to find this year….

I suspect most engineers will not want the work. Its auditing for gods sake. No fun. And there is no real work after this year.

Interesting reports

January 8, 2008

Never thought a manual would be interesting but there you go…

SBEM technical manual 

The SBEM technical manual is out – woohoo. Finally i can discover why the low carbon buildings are actually low carbon. SBEM is a program you have to run if you have a new building in the UK. A bit like an audit. Problem was – the methodology was hidden and the best way to get past it was to install air conditioning in buildings. Its way harder to get a naturally ventilated building through SBEM than an air conditioned one……

UKGBC low carbon buildings report

Since the green council has taken over the large building side of the UK governments low carbon strategy its interesting to see what they want (report here). Mainly being negative about the present intiatives (though with fixes) and keeping with this silly idea i keep seeing – we should allow off site or near site renewables. This won’t work. Sadly this shows the engineers are not talking to the lawyers. Our electricity and gas industry is really really regulated. Say you install offsite windmills to power a block of flats. As a flat owner if you want to swap supplier of electricity it is easy – unless you deliver so called “private networks” you can’t force soemone who buys a house / buildings to use a certain electricity supplier. They can and will swap. Given that these so called low carbon schemes have payback periods of less than zero then you have a recipe of the electricity generating bit folding within a few years as people who move into flats, etc moving suppliers and the more expensive low carbon electrity being used by no-one. I prefer the google sort of thinking – RE<C.

Blogger negativity

January 3, 2008

I wrote this blog to earn to write and i was struck by adam curtis’s comments about blogging in general. He’s a fairly cool director of documentaries i wish i saw (Power of Nightmares, etc). Anyway the quote i was struck by was..

First of all, the people who do blogging, for example, are self-selecting. Quite frankly it’s quite clear that what bloggers are is bullies. The internet has removed a lot of constraints on them. You know what they’re like: they’re deeply emotional, they’re bullies, and they often don’t get out enough. And they are parasitic upon already existing sources of information – they do little research of their own.

- Adam Curtis: The TV elite has lost the plot

I just did that on my previous post. Mmmmm must do better.

Another day passes and a new tower is being built (hat tip – RatandMouse). Its called the Strata, developer – Multiplex (of Wembley fame – smirk) and Hamiltons are the architects. No word of who is doing the services – bit worrying if, as the blurb says the building is “Adaptable to planned future developments in sustainable technologies within the Elephant & Castle area”.

 Anyway some points:

1) Three 9m wind turbines will probably only produce about 18kW – 30 kW total at peak (based on Proven energy website). Not much for such a high visibility building. Why didn’t they just increase the insulation or better the spec of the windows?

Answer - Because London demands a renewable tithe of 10% or more. Pointless really. I prefer lower fuel bills because the building is airtight and well insulated not some free lighting in stairwells which saves me ooooooh £6 a year.

2) It looks like they only did what the council forced them to do and they are window dressing things?

Answer – Yes.

3) What about the low energy lighting and lower energy costs?

Answer – So as a developer you’d think your engineers specify high energy lighting unless requested? As to the lower fuel bills the poor (on floors G-11; plebs down below – obviously) will watch TV so much on their mega plasma TV’s that this lower cost will disappear when all their equipment is left on (the plebs will not buy the 1 W/s standby TV’s)

4) Is there a proposed Energy Performance Certificate available?

Answer – nope they prefer to say how much better they are than the benchmarks (which are set very very low) – “current and evolving UK building regulations on sustainability by 13%”. Sigh all benchmarks are pretty much beaten by this level.

5) Are you being unfair? Didn’t they go for all those additional design standards (Lifetime Homes Compliant, EcoHomes Very Good, Secure By Design)?

Answer – If they weren’t forced by the planning officers or whoever is looking after the plebs then yes. It is impressive. You’ll notice they haven’t said where they exceeded what was required. That’s the problem with developers – they always look to cut corners and do the minimum. It just looks like they (Multiplex) have got to build a big skyscraper if they could green the building and give the plebs some space to live. Is this what planning is?

Recycling for a year

January 2, 2008

I’m interested in sustainability – hell we all are. But Ari Derfel kept all his rubbish for a year. I’m impressed.

 One of his lessons was: “Recycling sucks”. I recycle but this does feel part of the green fatigue.

We shall see.
