Non Domestic EPC Conventions for Northern Ireland Issue 2.0: 17 January 2011
These conventions (Issue 2.0), will also apply to assessments in Northern Ireland (with a small modification at 2.03, 3.02 and 3.05 ) and must be applied by all NDEPC certified energy assessors. Please note that the 'new' conventions must be applied on the same date. For audit and management purposes, the conventions must be applied on the dates shown in the 'Implementation Date' column on the right-hand side of the table. These conventions will be included as part of future quality assurance checks of the assessments you have undertaken, and the EPCs you have produced, thereafter.
Table to be substituted at 2.03 for Northern Ireland in place of the England and Wales table.
The SBEM default value of 25 m3/hr m-2 for all existing buildings shall be amended as follows:
|1st June 2010|
Table to be substituted at 3.02 for Northern Ireland in place of the England and Wales table.
|3.02||Adjacency assumed - party walls||
Unless evidence to the contrary is readily and easily available, all buildings adjoining that building or part building which is being assessed, are assumed to be conditioned unless they are of Planning Class B3 and B4 in which case they are assumed to be unconditioned.
|1st June 2010|
Table to be substituted at 3.05 for Northern Ireland in place of the England and Wales table.
|3.05||Inadequate or no fixed building services in existing buildings.||
Where there are inadequate or no fixed building services, in an existing building, the following guidance should be followed as appropriate. Note: where the building and fit out meet the first fit out definition in Technical Booklet F2 then the guidance in that document must be followed. The following guidance is therefore applicable only for existing buildings which have already had services installed and to which the term subsequent fit out would apply.
