Introduction
The European Energy Performance of Building Directive - EPBD (EU) 2024/1275[1] aims to improve
the energy éfficiéncy of buildings in the European Union. It sets requirements to reduce the energy
consumption of new and existing buildings and to promote the use of renewable energy. A key aspect
of the Directive is to promote sustainable building practices and improve energy performance in order
to support the EU’s climate change objectives and accelerate the transition to a low-carbon economy.
The Directive aims to improve living comfort while minimising the environmental impact of buildings.
With reference to Article 13(9) of the EPBD, Member States need to set requirements to ensure that
non-residential buildings with a rated output for heating, air-conditioning or combined space heating
and ventilation systems or combined air-conditioning and ventilation systems of more than 290 kW are
equipped with building automation and control systems by 31 December 2024 and non-residential
buildings with a rated output of more than 70 kW by 31 December 2029, where technically and
economically feasible.
With reference to Article 13(10), these building automation and control systems need to be capable of
continuously monitoring, logging, analysing and adjusting energy consumption, assessing the energy
éfficiéncy of the building, detecting éfficiéncy losses of technical building systems and informing the
person responsible for the installations or technical building management of ways to improve energy
éfficiéncy, enabling communication with connected technical building systems and other devices in the
building and being interoperable with technical building systems of different proprietary technologies,
devices and manufacturers. Indoor environmental quality monitoring is to be introduced by 29 May
2026.
It is necessary to prove the performance of Building Automation and Control Systems (BACS) in the
buildings falling within the set scope. This will help national market surveillance authorities distinguish
between buildings complying with the legislation and those that do not comply, and which, therefore,
need to improve the BACS to the level required.
Considering this, this checklist complemented by a self-declaration form for building owners to assess
their level of BACS performance was developed.
1 Scope
This document is a clear, effective and applicable guideline for demonstrating the performance of
building automation and control systems (BACS) in non-residential buildings that fall within the scope
of the European Directive Energy Performance of Building - EPBD (EU) 2024/1275 [1].
It has been developed for national policy makers, building planners, building owners and building
inspectors to support them in planning new buildings and evaluating existing ones.

5 Benefits, structure and content of the checklist
5.1 Benefits of the checklist
The following list explains the advantages and bénéfits of the checklist for national decision-makers,
building designers, building owners and building inspectors to support them in the planning of new
buildings and the assessment of existing buildings:
Building Inspectors: Compliance needs to be confirméd by the national market surveillance
authorities, for instance, a building inspector. Therefore, the checklist includes spot-checks intended to
verify whether all the necessary aspects of functionality can be provided by the installed BACS.
Building Owner: In order to make compliance vérificâtion more éfficiént and effective, this TR proposes
a separate self-declaration designed to be used by the building owner or a technical expert representing
the building owner. This will help the owner asses their BACS compliance in preparation for the
compliance vérificâtion by the national market surveillance authorities. Furthermore, it will inform the
owner about the necessary supporting documentation and the checks carried out by the building
inspector.
Building Designer: The technical spécificâtions of new buildings and renovation projects in the design
phase contain the requirements for supporting records to ensure the EPBD BACS capabilities are met.
The checklist provides the designer with the necessary clârificâtions to overcome any ambiguity within
the compliance requirements in the legisl
ation.
National policy makers: Following the formal transposition of the EPBD, many Member States are
approving further implementing decrees, specifying technical aspects which were not included in the
first transposing provisions. The checklist will be a helpful practical tool for the legislator to clarify
details about what the functionalities mean in practice.
Please note that the checklist sets the minimum requirements to comply with the EPBD requirements.
Users can provide more capability but not less than what is written in the checklist.
5.2 Checklist structure
The BACS compliance vérificâtion checklist is structured as a table, with the top row introduction form
as shown in Table 1. Table 2 provides an explanation of the content that needs to be filléd in the checklist
by the inspector.
A separate self-declaration (see Annex A ) designed to be used by the building owner or a technical
expert representing the building owner is the finâl element of the BACS compliance vérificâtion toolkit.

end of the row to clearly separate the legal requirements
from recommendations
This guide provides a three-step process for demonstrating the conformity of building automation and
control systems in non-residential buildings with the European Performance of Buildings Directive
(EPBD).
Before the core section of the BACS compliance vérificâtion checklist5.5, there are two preliminary
sections "Effective rated output" 5.3 and “Compliance vérificâtion” 5.4. These ensure that the building
falls under the scope of the EPBD BACS compliance requirements. The sample HVAC architecture
graphic in Figure 1 demonstrates the scope of the equipment covered by the BACS compliance
vérificâtion checklist.
Key
Red heating systems included in the total Effective rated output (Art. 12, Par. 9)
Green ventilation systems included in the total Effective rated output (Art. 12, Par. 9)
Blue air-conditioning systems included in the total Effective rated output (Art. 12, Par. 9)
Figure 1 — Example HVAC architecture graphic
5.3 Effective rated output
The BACS compliance vérificâtion needs to be conducted only if the Effective rated output for heating/
air-conditioning systems or systems for combined space heating/air-conditioning and ventilation in
the building is over 290kW by 31 December 2024 or over 70 kW by 31 December 2029. (EPBD Article
13, Paragraph 9). Through a series of questions, this section provides information on the individual
values of the Effective rated output for the technical building systems in this particular building. When
a technical building system (e.g. Air-conditioning system) is not present in a building, the respective
BACS checks will not be applicable and need to be clearly marked with N/A.
5.4 Compliance verification
The compliance vérificâtion needs to be conducted only if building automation and control systems
(BACS) capabilities apply to a considerable extent in the building.
For the BACS capabilities to have the EPBD intended impact on the building energy performance, there
needs to be a minimum coverage of BACS-controlled heating, ventilation, and air-conditioning building
systems. In this section a series of questions confirm the proportion of technical building systems which
are controlled by BACS. It is recommended that the compliance vérificâtion is conducted only if BACS
apply to a considerable extent in the building.
5.5 BACS Coverage
After ensuring the building can be considered eligible for the compliance check, individual compliance
checks for the BACS coverage Table 3 are clustered into four different groups each of them representing
one of the four capabilities listed in [1]EPBD Article 13 Paragraph 10.
References to relevant control functions in EN ISO 52120-1:2022 [2] are noted where necessary.
Table 3 — BACS Coverage
(a) continuously monitoring, logging, analysing and allowing for adjusting energy usage
(b) benchmarking the building’s energy éfficiéncy, detecting losses in éfficiéncy of technical building
systems, and informing the person responsible for the facilities or technical building management
about opportunities for energy éfficiéncy improvement
(c) allowing communication with connected technical building systems and other appliances inside
the building, and being interoperable with technical building systems across different types of
proprietary technologies, devices and manufacturers
(d) by 29 monitoring of Indoor environmental quality
May 2026
The building inspector needs to use the “Response” column checkboxes “Yes” and “No” to mark the
result of the spécific check for each row. For each compliance vérificâtion check, if the answer in the
self-declaration was positive, the supporting records are available, and the spot-check has confirméd
it, “Yes” needs to be marked in the checkbox. If any of these are missing, “No” needs to be marked. To
comply with the requirements of EPBD, all rows in the three groups of functionalities need to be marked
with a “Yes”. If any row is negative, the BACS do not comply with the requirements and therefore needs
to be improved to the required state.
6 Checklist
6.1 Effective rated output
STEP 1: The BACS compliance vérificâtion needs to be conducted only if the Effective rated output for
heating/air-conditioning systems or systems for combined space heating/air-conditioning and
ventilation in the building, as listed in Table 4 , is over 290kW by 31 December 2024 or over 70 kW by
31 December 2029.
