Introduction
The set of EPB standards, technical reports and supporting tools

In order to facilitate the necessary overall consistency and coherence, in terminology, approach,

input/output relations and formats, for the whole set of EPB-standards, the following documents and

tools are available:
a) a document with basic principles to be followed in drafting EPB-standards:

CEN/TS 16628:2014, Energy Performance of Buildings — Basic Principles for the set of EPB

standards [1];

b) a document with detailed technical rules to be followed in drafting EPB-standards;

CEN/TS 16629:2014, Energy Performance of Buildings — Detailed Technical Rules for the set of

EPB-standards [2];
c) the detailed technical rules are the basis for the following tools:

1) a common template for each EPB-standard, including specific drafting instructions for the

relevant clauses;

2) a common template for each technical report that accompanies an EPB standard or a cluster of

EPB standards, including specific drafting instructions for the relevant clauses;

3) a common template for the spreadsheet that accompanies each EPB standard, to demonstrate

the correctness of the EPB calculation procedures.

Each EPB-standards follows the basic principles and the detailed technical rules and relates to the

overarching EPB-standard, EN ISO 52000-1:2017 [3].

One of the main purposes of the revision of the EPB-standards is to enable that laws and regulations

directly refer to the EPB-standards and make compliance with them compulsory. This requires that the

set of EPB-standards consists of a systematic, clear, comprehensive and unambiguous set of energy

performance procedures. The number of options provided is kept as low as possible, taking into

account national and regional differences in climate, culture and building tradition, policy and legal

frameworks (subsidiarity principle). For each option, an informative default option is provided.

Rationale behind the EPB technical reports

There is a risk that the purpose and limitations of the EPB standards will be misunderstood, unless the

background and context to their contents – and the thinking behind them – is explained in some detail

to readers of the standards. Consequently, various types of informative contents are recorded and made

available for users to properly understand, apply and nationally or regionally implement the EPB

standards.

If this explanation would have been attempted in the standards themselves, the result is likely to be

confusing and cumbersome, especially if the standards are implemented or referenced in national or

regional building codes.
Therefore each EPB standard is accompanied by an
...
