Ecotect tutorial
I made this a really long time ago, and it still isn’t finished, but it woul’d be better for the world if it was out there making people happy (what rot).
I’ve been working on an Ecotect training document for a while, it is still a work in progress, but see what you think so far. Ecotect for site analysis
as it is a work in progress, if you want to put notes on the tutorial and send it back, that’d be very much appreciated!
I snuck it onto the tutorials page a while ago, but I didn’t announce it. If there is enough enthusiasm in the comments I’ll carry on working on it.

Chasing a made up number’s source…
A while ago I wrote about the magical 45% number that is cited whenever anyone tries to justify their involvement in a built-environment project that seeks to reduce CO2 emissions.
In the last few months I’ve made a few steps in finding the source of this number, and it seems that it might pay to be a bit more careful while using it in future. (Seems – I’d like to know if anyone knows better.)
The most likely source of the number comes from CIBSE guide F. (Thanks Sophie for finding it, I know I’ve been a terrible bore about this subject.)
| domestic | Commercial & Public | Industrial |
| 29% | 13% | 4% |
all adds up to 46% - eureka! It has been found! Lets just cross our Ts and dot our Is to be sure.
This table comes from the ‘Digest of UK energy statistics (London: The Stationery Office)’, and was published in 2000. There are a couple of tricky things here, one glaring, and one that takes a bit of digging. Firstly, 2000 was 11 years ago, and the odds are that the data are even older. 12 years ago I looked like this! These data are published annually and a lot happens in 12 years – is it still a valid number to be quoting? I had a look, and the stationary office doesn’t publish that data any more, it is the the Department of Energy and Climate Change‘s thing.
The places that I’ve been most successful in finding useful information are:
- Eurostat:Using official statistics to calculate greenhouse gas emissions: A statistical guide html version, pdf.
- Department of Energy in the US
If there is an up to date figure then I’d love to see it, it’d make me feel like much less of a fraud when I try to convince people about this kind of thing.

Major study – for those with a lot of patience
There will be a version of this available soon in a massively reduced format, but for those of you with a penchant for punishment, or perhaps just an unquenchable interest in my ability to drivel on for a hundred pages, here’s my Major study in all it’s pdf glory!

bpquiz just crept over one hundred
bpquiz, the data gathering website for my major study has just had its 100th response. There is another 3 weeks left of data gathering, so maybe the target of 200 isn’t so far off!
If you haven’t had a go:
