Dear Sir or Madam,

I am aware that the water calculator that is used to calculate water use for new houses under the 'Code for Sustainable Homes' has recently changed. I would like to see the technical reports that underly this change, in particular the scientific justification for the 'normalisation factor'.

Yours faithfully,

Dear Jeannette Henderson,

Please could you update me on the progress of this request.

I had assumed that since the water calculator has been updated, there would be background reports on the evidence that spelt out the way in which these changes had been decided on. The normalisation factor was not present in the initial water calculator, so I would expect you to have some kind of report on why it is necessary and how the value is arrived at?

The background and evidence base for the energy requirements and SAP are well documented and in the public domain. Since the water element of CSH is also mandatory, it is difficult to see why a similar range of background information is not available.

In short, I don't think I am asking a particularly complicated question, so I am rather frustrated at how slow the response is in coming!

Yours sincerely,

Margery Slater

This request was made in December last year. Despite following this up a couple of times, there has been nothing other than a 'holding' response from DCLG.
