Is the set of EPB standards used exclusively for energy performance certification or also for design?
The most time-consuming task when preparing a calculation for an energy performance certificate or compliance check, is describing the building with all it’s details. So, if the same calculation procedure can be used also for design calculations it makes life much easier. Moreover, you ensure that you use compatible definitions and assumptions. For exactly this […]
Which stakeholders were involved in the development of the set of EPB standards and how do they take into account the feedback from the market?
The responsible ISO and CEN technical committees (TCs) have working groups (WGs) where the technical experts are cooperating to prepare new standards or revise existing standards. The technical experts are nominated by the National Standards Bodies (NSBs), the CEN/ISO members. The background of these experts is very diverse: designers, industry, practitioners (dealing with system or […]
Do the EPB standards go beyond a single building, such as networks? Do they cover demand-side flexibility?
First of all, , the overarching EPB standard, introduces the term “building portfolio”: a set of buildings and common technical building systems whose energy performance is determined taking into account their mutual interactions. An example of common technical systems is an energy generation system (PV panels, wind turbine, cogeneration unit, boiler, etc.) serving the building […]
Why is the calculation of the overall energy performance of a building split into separate EPB standards?
Why is the calculation of the overall energy performance of a building split into separate EPB standards and not combined into an all-in-one standard (at least all EPB standards that are part of the overall EP calculation)? In general, the ISO and CEN standards making process is handled by various technical committees or TCs as […]
Will the EPB standards provide guidance for collecting input data for use in the calculations, e.g. a complete list of input parameters?
Yes, each EPB standard has a list of all input and output data. Also, in each of the that are available <link> you can find the list of input parameters for the associated EPB standard. The challenge, however, is to see through these “blunt” lists of input data. You could easily say that the Pareto […]
Do the EPB standards contain energy performance (EP) requirements?
As a general rule, CEN and ISO standards as such do not impose any regulation. Laws and regulations may refer to standards, because standards provide harmonized specifications (e.g. terminology, key characteristics) and harmonized methods for tests or calculations. The EPB standards contain methodologies to assess the EP, and specifications of EP characteristics, including EP indicators, […]
Why are the technical reports not integrated in the EPB standards? It would make the combined document less expensive.
The correct understanding and application of EPB-standards requires extensive informative clarification such as: reason for the choices made in selecting methods; intended use of the different methods; correct evaluation of data input; information to those responsible for national implementation. If the informative content is mixed with the normative content, the standards may become confusing and […]
