Introduction
Buildings are built and operated serving a specific purpose, e.g. as an office workspace, a manufacturing
floor, or a data centre. In each case, the usage of the space requires specific environmental conditions, e.g.
temperature, light level or air quality, which is provided.
Increasing the efficient usage of energy to provide these environmental conditions is a key aspect of
building design addressed in EN ISO 52120-1, Energy Performance of Buildings — Energy performance of
buildings — Part 1: Impact of Building Automation, Controls and Building Management.
Energy efficiency requirements cannot be fulfilled by optimizing the primary systems of a building alone.
A holistic view on the building and especially on the room control systems for lighting, solar protection
and HVAC is the basis for optimizing the energy efficiency of buildings. This requires integration of the
room and building controls and management systems from the design phase through installation and
commissioning to the building operation.
The planning process for the technical infrastructure of a building and its spaces includes several steps
starting with a rough set of requirements. With each step in the planning process the design becomes
more detailed. First basic design choices or decisions allow for a budget estimate. These first design
choices may be documented as depicted in Figure 1.
Figure 1 — Example for documentation of design choices for technical infrastructure of a
building (Source: SN 502411:2016 / SIA 411:2016)
Figure 1 shows the equipment required for the different technical building disciplines (heating, cooling,
ventilation, lighting, solar protection) in the space including energy related interconnections between the
equipment of the respective disciplines. The schema depicts source/sink, conversion, storage,
distribution, and emission elements and their interconnections in a simple manner. This is a high-level
view on the mechanical and electrical equipment. It does not yet include the automation requirements
associated with the equipment.
In a further planning step, the control functions (BAC functions) associated with the technical
infrastructure equipment of a building are added as depicted in Figure 2.
Figure 2 — Example for documentation of design choices for technical infrastructure and
associated control functions of a building (Source: SN 502411:2016 / SIA 411:2016)
The column “usage/operation” contains control functions required for user interaction with the technical
building infrastructure in the space and/or for super-ordinated (e.g. building-wide) functions and
requirements.
Whereas the control functions are determined by the technical building equipment and the user
operation interface in general, the sophistication of these control functions is determined by the desired
level of energy efficiency of a building or comfort and operational requirements. Hence, both views, the
desired level of energy efficiency of a building and the comfort and operational requirements, are
considered and documented such that this documentation serves as a requirement specification for
building control applications (heating, cooling, ventilation, lighting, solar protection) in a space.
In Figure 2, BAC functions have been added to the equipment. The labels refer to BAC functions listed in
EN ISO 52120-1:2022, Table 5. These BAC functions are not specified in detail in EN ISO 52120-1.
Clause 5 of this document provides a method to transfer energy performance, comfort, and operational
requirements as defined in EN ISO 52120-1:2022 into a more detailed specification of building
automation functions.
Refer to EN ISO 52120-1:2022, Table 5, for a list of functions contributing to achieve the desired level of
energy performance. Whereas EN ISO 52120-1:2022 only provides a very brief description of the
functionality, Clause 5 contains a more detailed description.
NOTE Application of automated control improves the energy performance of buildings. Clause 5 of this
document covers automated control applications only. Any manual or non-automated control listed in EN
ISO 52120-1:2022, Table 5, is not covered in this document.
For the purpose of clarity, each subclause in Clause 5 contains a reference in square brackets to the
corresponding entry in Table 5 of EN ISO 52120-1:2022 directly after the sub-clause heading.
The more detailed description includes information about mandatory and optional inputs as well as
mandatory and optional outputs for the control function. The control function is not described in detail
but rather is a “black box” as the actual implementation may be project or manufacturer specific.
Figure 3 provides an informative schematic view with the function (box), mandatory (blue) and optional
(grey) inputs and mandatory (blue) and optional (grey) outputs. The informative schematic drawing also
shows if inputs may be controlled, e.g. by manual operation or by a schedule and if output values are
associated e.g. with an alarm or a trend.
Figure 3 — Informative depiction of control application scheme for Heating control – Emission
control – Type 1: Central automatic control
Clause 5 contains in each sub-clause a brief description of the control function itself, the target of the
function, different operating modes, where applicable, and a description of the inputs and outputs of the
function. Optionally, parameters and implementation equipment may be described.
For some of these functions more than one version is described, covering different technological
implementations.
Building control functions may be associated with a specific zone, a room, a building segment, or the
whole building.
The result of applying Clause 5 is a collection of building automation control function blocks. This does
not yet depict how these blocks work in detail or how they are linked to each other. A more detailed
control scheme description can be provided using the function blocks described in Clause 6.
Clause 6 of this document provides function blocks, which can be used to describe building control
functions in more detail independent of a specific building control system or vendor.
Applications can be described by a combination of sensor input, actuator output, user interaction, and
control and monitoring functions. Certain functions in a room (e.g. presence detection) may be shared by
two or more applications. A common set of function blocks covering sensor input, actuator output, user
interaction, and control functions for the different applications in a room serves as the basis for
describing room automation, controls and management systems.
Using a typical example, Figure 4 shows the relationship between sensor, display/operation, control and
actuator functions. Information exchanged between functions is provided from outputs to inputs.
Physical inputs and outputs associated with Sensor and Actuator functions are not depicted in the figure.
As some functions may require parameters these are also depicted in each function block.

A sensor function typically includes a physical input (e.g. a temperature sensor, not depicted in Figure 4)
