					Calculator for assessment of rates relief (Northern Ireland) - Zero-Carbon Home

Instructions

1   Undertake calculation for the dwelling by SAP 2005 using an approved SAP 2005 calculator.

2   Ascertain the heat loss parameter (HLP) from the either SAP or DER worksheet, item (38).

3   Obtain the DER as reported by approved software from Regulations Checklist or DER worksheet.

4   Obtain the CO2 emissions per square metre of total floor area from the SAP worksheet, item (113)
    or (120*).

5   Ascertain the total floor area from the either SAP or DER worksheet, item (5).

Enter the above values on the Calculator tab. The results are shown when these items have been specified.

6   Enter data where relevant to the particular case for biomass CHP (from the DER calculation worksheet).

7   Enter additional allowable electricity generation (calculated outside of the SAP worksheet).

8   The dwelling can be considered for rates relief in Northern Ireland if each of the conditions show "Yes".

9   Go to the Assessor tab and complete the green cells.

10 Go to the Certificate tab and print it.


It may be helpful to look first at the example.

For further information see    www.nidirect.gov.uk/low-carbon-homes.htm

Approved SAP 2005 software may include assessment for rates relief.
This spreadsheet is intended for use in conjunction with software that does not produce an appropriate
zero-carbon home certificate.
