Status/Planning EPB-project
• During 2015 expected closing enquiries for most of the draft EPB-standards (EN and EN-ISO)
• The OAS: prEN ISO/DIS 52000-1 is now at enquiry stage Closing date 2015-11-27.
• The OAS connected TR is available as N-document at CENTC371, ISO/TC163 and ISO/TC205 level, voting on TR is expected parallel to the FV of the OAS around mid-2016.
• For all EPB standards: The end of 2015, some begin 2016 most Enquiry comments to be resolved and draft Formal Vote versions ready at TC level.
• After voting we expect that by the end of 2016 / beginning 2017 all EPB-standards will be published as EN or EN-ISO standards

Observation in Europe
• One of the important instruments to support the proper implementation of the EPBD policy is the modularly structured, transparent, unambiguous, but flexible* set of EN and ISO EPB standards
*: for local climate, national legal framework, building tradition, building use, existing local energy-infrastructure, etc…
REHVA-sem'15 10/05/2015
Why we need this flexibility and transparency
Flexibility: to be suitable for:
– local climate,
– National/ regional legal framework,
– National/ regional building tradition and building use,
– existing local (national or regional) energy-infrastructure,
– Etc…
Transparency: to accommodate a levelled playing field when:
– Expressing the EP of buildings
– offering various energy (or CO2) saving solutions

Revised OAS
• Improved description of zoning procedures, if zoning is chosen : rules to be followed are given
• Balanced attention to monthly and hourly approaches
• Improved definitions
• Given default values and choices (as in all EPB standards) are informative via the Annex A/B approach
• Annex A/B resolves many questions related to national/regional choices or conventions (think of the primary energy factors or the precise definition of nearby and distant in this context)
10/05/2015 REHVA-sem'15
The modular structure supports Flexibility and transparency of the
set of EPB standards
• The OAS as the backbone of the total set of EPB standards
• By not using one of the standards it is clear which in-/output data have to be declared to replace this module

Connection of custom modules: input data
Each calculation module needs two types of input data:
• Data coming from other parts of the calculation: (required energy output, operating conditions, etc.),
• Data specified only when using this module, «local data» Typically these are product data and application conditions like localization of components (boiler, pipes indoor/outdoor)
Conditions to be satisfied by custom non-EN/ISO modules:
• The input data of the replaced module, together with custom local data, shall be complete, to be able to perform the calculation according to the custom module.
• The available input data coming from other parts are listed as «operating conditions» in the input data specification of the replaced EN/ISO standard module
10/05/2015 REHVA-sem'15
Set of EPB standards: unambiguous but flexible (allowing national choices, boundary conditions and input data)
Each EPB standard contains:
• Annex A (normative): template for choices and input data needed for using the standard
• Annex B (informative): informative default choices and input data
• In general:
– Each individual user of the EPB standard is free to create his/her own data sheet according to the template of Annex A (~ replace the default choices and values of Annex B)
10/05/2015 REHVA-sem'15
Explained in a note in the OAS and each EPB standard’s Annex A and
Annex B “
NOTE
In particular for the application within the context of regional or national legal requirements.
These choices (either the default choices from Annex B or choices adapted to national/regional needs),
but in any case following the template of this Annex A
can be made available as National Annex or as separate (e.g. legal) document.
”
10/05/2015 REHVA-sem'15
The OAS and all developed EPB
standards • have a modular and transparent structure, an
unambiguous framework for default values and choices
• Include default values and choices in annex B to most of the EPB standards;
• Include the possibility as user, national or regional authority, to create (national) Annexes based on the Annex A template;

• prEN16798-1: Indoor environmental input parameters for design and assessment of energy performance of buildings addressing indoor air quality, thermal environment, lighting and acoustics - (revision of EN 15251)
• This standard gives the opportunity to declare next to the EP of buildings the IEQ-classification in a standardised way

National implementation of EPB standards:
• National cover page and the Introduction text in the EPB standards: this text allows the NSB’s (or authorities) to include information regarding the position of the EPB standard in their national regulation, version indication etc…
• NSB’s can publish a National Annex to each EPB standards where they make use of the Annex A template. A National Annex is not an Annex A.
• A NA is a separate document, it does not have to be attached to the standard it refers to
• A NA could include more additional information! More National Annexes could be developed, e.g. for different building functions etc…
10/05/2015 REHVA-sem'15
The main target-groups of the set of EPB standards
It is expected, if the default values and choices in Annex B are not followed due to national regulations, policy or traditions, that:
– Either the NSB will consider the possibility to add or include a National Annex in agreement with the template of Annex A.
– Or the national or regional authorities will, in the building regulations, reference the standard and prepare data sheets containing the national or regional choices and values, in agreement with the template of Annex A.
• Further target groups are: – users of the voluntary common European Union certification scheme
for the energy performance of non-residential buildings
– other Pan EU or Global parties wanting to motivate their policy by classifying the building EP for a dedicated building stock.
– Global Innovators on the EP-market 10/05/2015 REHVA-sem'15

Collaboration with ISO
10/05/2015 REHVA-sem'15
Status of the ISO interaction
• An active process of interaction for the Overarching Type of standards through the JWG of ISO TC 163 & 205
• for the other CEN standards via the different WG’s of ISO TC 163 and 205, Sharing early prelim draft texts
• Sharing experts in the ISO and CEN teams working on these standards, with the ultimate goal to agree on ISO standards
• A challenge given the geographic and other differences in the building sector, given the very tight time scale at CEN level, for EPB standards under some of the CEN TC’s the cooperation with ISO is for the time being informal (no parallel voting).
• In ISO a series of numbers has been reserved for all EPB standards (52000----52150)
10/05/2015 REHVA-sem'15
Summary • CEN and ISO are on a fast track to develop the
procedures and standards for buildings, systems and products towards low energy buildings that could meet the nZEB targets
• The developed EPB standards and procedures will offer the flexibility to apply them throughout Europe and Globally
• CEN and ISO cooperate to achieve a common set of EPB standards ( for ISO in the 52000 series: 52000—52150 have been reserved)
