General Information
Overview - CEN/TR 18081:2024 (Smart building)
CEN/TR 18081:2024 is a Technical Report from CEN/TC 247 that explains the term “smart building” in the context of building automation, controls and building management (BACS/BMS). Rather than prescribing products or protocols, it describes the features, purpose and practical means to achieve smart buildings over their full lifecycle - covering functional adaptability, lifetime energy balance and material reuse/recycling. The report aligns with related standards (EN 13321‑1, EN 14908, EN 50090, EN ISO 16484) and references European work such as the Smart Readiness Indicator (SRI).
Key topics and technical requirements
- Core features of a smart building
- Adaptable building functions (structure, infrastructure, operation) to meet evolving user needs.
- Life‑time energy target: building generates or saves as much energy over its lifetime as was embodied and used to build and operate it.
- Material/resource circularity: structural and infrastructural components designed for reuse or recycling.
- Functional viewpoints
- Building structure, infrastructure (ducts, piping, cabling), and operation (energy, HVAC, lighting, security, EV charging, access control).
- SRI impact categories: energy efficiency, maintenance/predictive maintenance, comfort, convenience, health & wellbeing, occupant information, energy flexibility/storage.
- Means to realize smart buildings
- User interfaces that engage occupants in energy targets.
- Efficient use and documentation of resources via BIM and a Digital Twin database.
- Control of local energy generation, demand‑side management, and interaction with external systems (e.g., smart grid).
- Collection, analysis and use of operational data for predictive maintenance and optimization.
- System capabilities
- Continuous monitoring, logging and adjustable energy use.
- Benchmarking and loss detection with actionable alerts.
- Interoperability across devices and vendors and attention to cyber security and informational structures for Digital Twins/BIM.
Practical applications and who uses it
- Building owners and investors: set lifecycle energy and reuse targets; define required functions.
- Architects and designers: specify adaptable structures and infrastructure for future reuse.
- Facility and energy managers: apply monitoring, benchmarking and predictive maintenance practices.
- Systems integrators and BACS/BMS vendors: design interoperable, secure control systems and digital interfaces.
- BIM/Digital Twin specialists: document materials, resources and operational capabilities in standard formats.
- Policy makers and assessors: align certification, SRI implementation and lifecycle energy goals.

European foreword
This document (CEN/TR 18081:2024) has been prepared by Technical Committee CEN/TC 247
“Building Automation, Controls and Building Management” the secretariat of which is held by SNV.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
CEN/TC 247, “Building Automation, Controls and Building Management” - in collaboration with
CLC/TC 205 “Home and Building Electronic Systems (HBES)” - has prepared this document to create a
report in which the view of both CEN/TC 247 as well as CLC/TC 205 on the aspect of smart buildings is
documented.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
Introduction
The use of a building changes over its lifespan and adapts to the changing usage and functional
expectations of the users regarding desired comfortable shelter, living and/or working space.
This can relate to:
— building structure;
— building operation;
— energy efficiency;
— maintenance and fault prediction;
— comfort;
— convenience;
— health and wellbeing;
— information to occupants;
— energy flexibility and storage.
The goal of integrating building automation control systems is to ensure maximum cost-neutrality and
environmental compatibility for the owner over the entire service life of a building. If this goal is
fulfilled for a specific building, then this building would be regarded as “smart”.
