Overview - EN 15378-1:2018 (SIST)

EN 15378-1:2017 (EN 15378-1:2017) is a European standard for the energy performance of buildings focused on the inspection of boilers, heating systems and domestic hot water (DHW). It defines inspection procedures and assessment methods (Modules M3-11 and M8-11) for existing heat generators and accessible parts of heating systems to support energy conservation and environmental performance improvements.

The standard covers a wide range of heat generator types:

• combustion boilers (gas, liquid, solid fuel) for heating and/or DHW
• electrically and gas-driven heat pumps
• solar thermal (thermal solar) systems for DHW and space heating
• cogeneration and other heat generator types

It inspects subsystems including generation and controls, distribution networks, emitters, space heating control, heat storage and DHW systems.

Key technical topics and requirements

• Inspection procedures for heat generators and whole heating systems, including visual checks, functionality tests and meter readings.
• Inspection levels and templates (normative Annex A; informative defaults in Annex B) that define choices, input data and references.
• Performance evaluation and advice criteria to identify improvement opportunities (replacement, modifications, control upgrades).
• Sizing checks for generation equipment (boiler and other generators) to detect oversizing or undersizing risks.
• Controls, sensors and indicators assessment to evaluate thermostatic and central control effectiveness.
• Energyware consumption estimation and reference values for assessing consumption against benchmarks.
• Reporting: standardized inspection report formats, sample reports and flowcharts (Annexes C–E) and lists of possible improvement actions.
• Support for regulatory compliance with Directive 2010/31/EU (EPBD) Article 14 requirements for heating-system inspection.

Practical applications and who uses this standard

• Building energy assessors and qualified heating inspectors conducting field inspections and issuing energy improvement advice.
• HVAC engineers and consultants assessing boiler efficiency, control strategy and system sizing before retrofit or replacement.
• Facility managers and building owners seeking evidence-based recommendations to reduce energy use and emissions.
• Regulators and certification bodies implementing EPB (energy performance of buildings) schemes or national inspection requirements.
• Companies involved in renovation, retrofit or commissioning who need consistent inspection and reporting procedures.
