Introduction

This standard is part of a series of standards aiming at international harmonization of the methodology

for the assessment of the energy performance of buildings, called “EPB set of standards”.

As part of the “EPB set of standards” it complies with the requirements for the set of basic EPB

documents EN ISO 52000-1:2017 (see Normative references), CEN/TS 16628 and CEN/TS 16629 (see

bibliography [2] and [3]) developed under a mandate given to CEN by the European Commission and

the European Free Trade Association (Mandate M/480), and supports essential requirements of EU

Directive 2010/31/EU on the energy performance of buildings (EPBD).

This standard is clearly identified in the modular structure developed to ensure a transparent and

coherent EPB standard set in iso 52000-1. BAC (Building Automation and Control) is identified in the

modular structure as Technical Building System M10. However, other standards issued by ISO TC 205

deal with control accuracy, control functions and control strategies using standards communications

protocol (these last standards do not belong to the EPB standards set).

To avoid a duplication of calculation due to the BAC (avoid double impact), no calculation are done

in BAC EPB standard set, but in each underlying standard of EPB set of standards (from M1 to M9 in

the Modular Structure), an IDENTIFIER developed and present in the M10 covered by ISO 52120-1

is used where appropriate. These way of interaction is described in detailed in the Technical Report

(ISO/TR 52000-2:2017) accompanying the over-arching standard. As consequence, the Annex A and

Annex B concept as EXCEL sheet with the calculation formulas used in the EPB standards are not

applicable for this standard.

The main target groups of this standard are all the users of the set of EPB standards (e.g. architects,

engineers, regulators).

Further target groups are parties wanting to motivate their assumptions by classifying the building

energy performance for a dedicated building stock.

5 Description of the methods
5.1 Output of the method

This method covers the calculation of the building operation data that could be influenced and

optimized by a building management system. Those data are mainly related to:
— setpoint including set back,

— operation times of heating, ventilation, cooling and lighting systems including start-stop-

optimization,
— sequencing of multiple generators,

— building energy management and load management with regard to the utilization of local renewable

energy and local energy production,
— heat recovery and heat shifting,
— smart grid interactions, demand side management, and peak shaving.

Calculation is in general independent from the time step chosen but is according to the time-step of

the input.

It is important to be aware that the TBM functions not fully automated will have an impact on energy

performance of the building only in case if they are not only installed but actively used, i.e. that actions

are taken if monitoring results ask for it.
5.2 General description of the method(s)

This standard covers several functions of the application of the Building management system. Each

function is represented by at least one calculation method.

This standard covers 6 of the functions described in ISO 52120-1, table 4. This list of capabilities of

controls and BMS functions is not exhaustive. Energy efficiency performance of building depends of the

choice of control and BMS functions related to expected performance (following methodology described

in ISO 52000-1), their implementation, commissioning and exploitation. The functions are as follows:

— “Function 1 – set-points”, is meant for set-point definition and set back. This function refers to

function 7.1 in ISO 52120-1, table 4.

— “Function 2 – run-time” is intended for estimating run-times. This function refers to function 7.2 in

ISO 52120-1, table 4.

— “Function 3 – sequencing of generators” is intended for estimating the sequential arrangement of

different generators. This function refers to function 1.9 in ISO 52120-1, table 4.

— “Function 4 – local energy production and renewable energies” is intended for managing local

renewable energy sources and other local energy productions as CHP. This function refers to

function 7.5 in ISO 52120-1, table 4.
