BRL 9500-U 2024 – Energy Performance Assessment for Non-Residential Buildings
The BRL 9500-U is the Nationale Beoordelingsrichtlijn (National Assessment Directive) for the NL-EPBD® process certificate specifically governing the determination of energy performance in non-residential buildings (utiliteitsgebouwen) in the Netherlands. This 2024 edition was established by the Centraal College van Deskundigen (CCvD) of Stichting InstallQ on March 15, 2024, and declared binding as of April 15, 2024. It is officially designated by the Minister van Binnenlandse Zaken en Koninkrijksrelaties (Minister of the Interior and Kingdom Relations) under the wider Dutch regulatory framework, including the Omgevingsregeling and the Besluit bouwwerken leefomgeving (Bbl).
The directive defines the certification requirements for companies and advisors who record, calculate, and register energy performance reports. Its scope covers three primary project phases: the preventive check against Bbl rules for permit applications (toets Bbl), the assessment upon completion of construction or renovation (oplevering), and the evaluation of existing buildings for sale or rental (bestaand). The document explicitly structures the assessment process into two sub-sectors: basisopname (basic recording) and detailopname (detailed recording), each requiring specific professional qualifications and methodologies defined by NTA 8800 and ISSO-publicatie 75.1.
This document serves as the regulatory basis for the NL-EPBD® process certificate. It outlines the mandatory documentation, personnel competence standards, and the internal and external quality assurance protocols that certified organizations must maintain. The following sections detail the technical requirements for advisors, the components of a valid energy performance report, and the audit procedures conducted by accredited certification bodies.
Classification of Energy Performance Recordings
The directive distinguishes between two types of building recordings based on the availability of data and the project status. A detailopname is mandatory for new constructions and significant renovations where full technical specifications are available.
- Basisopname: Applied when detailed input data is missing; requires visual observation and simple retrieval methods as per ISSO-publicatie 75.1.
- Detailopname: Compulsory for toets Bbl calculations, buildings completed after January 1, 2021, and projects where specific BENG targets must be demonstrated.
- BENG-eisen: The Bijna Energieneutrale Gebouwen (Nearly Zero-Energy Buildings) requirements that all new non-residential buildings must satisfy.
- Utiliteitsgebouw: Any building or part thereof with a functional use other than residential, as defined in the Bbl.
Professional Competence of EP-U Advisors
The BRL 9500-U sets strict standards for the personnel performing the work. Only qualified EP-U advisors working for a certified organization can issue official reports. Competence is divided into levels matching the recording types.
- EP-U/B Advisor: Qualified for basic recordings (basisopname) and must hold a certificate of competence as defined in Bijlage 2a.
- EP-U/D Advisor: Qualified for both basic and detailed recordings (detailopname), with authority to calculate Rc-values and linear thermal bridges as per Bijlage 2b.
- Bij- en nascholing: Mandatory continuing education requirements set by the InstallQ board to maintain valid competence status.
- Vakbekwaamheidsbewijs: Official proof of competence that can be withdrawn in cases of fraud or failure to meet training requirements.
The Energy Performance Report and Registration
A valid energy performance report must include specific parameters that allow clients and regulators to verify compliance with national energy standards. Registration occurs via the national database, EP-Online.
- EP1: Yearly energy demand in kWh per square meter of usable floor area.
- EP2: Yearly primary fossil energy use in kWh per square meter.
- EP3: The percentage of renewable energy used by the building.
- Energielabel: The energy grade (letter) automatically generated upon registration based on EP2 results.
- Projectdossier: A mandatory file containing all calculations, drawings, photos, and manufacturer declarations (DoP) used for the assessment.
Quality Control and Auditing Procedures
Certification holders are subject to both internal and external quality monitoring to ensure the integrity of issued labels and reports. This includes regular audits and project-specific inspections.
- Interne kwaliteitsbewaking: Certified companies must perform at least one internal audit annually and check 2% of registered reports per advisor.
- Externe kwaliteitsbewaking: Accredited certification bodies perform office audits and on-site inspections (achteraf in het werk) to verify the accuracy of recording data.
- Kwaliteitshandboek: A mandatory manual describing all procedures for professional competence management, document control, and complaint handling.
- Projectcontrole: An inspection where the certification body verifies the software input against the physical building characteristics or the project file.
Frequently Asked Questions
When is an energy performance report mandatory for a non-residential building?
A report is required during the permit application process (toets Bbl), upon completion of a new or renovated building (oplevering), and at the time of sale or rental (bestaand).
What is the validity period of an energy label for a utility building?
The energy label remains valid for a maximum of 10 years from the date of issuance.
Is it possible to include improvements made after the initial recording?
Yes, improvements can be included through a process called herlabelen, provided they were implemented within 24 months of the original recording date.
How long must a certified company store building project files?
The project file and the digital calculation data must be preserved for at least 15 years after the completion of the assignment.
Who is allowed to perform a detailed recording (detailopname)?
Only a qualified EP-U/D advisor is authorized to perform detailed recordings for non-residential buildings.
What happens if a certification body identifies a critical deviation in a report?
The certification holder must provide a new energy performance report to the client, update the registration in EP-Online, and undergo an additional project check.
Can a company use recordings from a different certification holder?
Yes, but the data must be verified for the specific building, and the registering party remains fully responsible for the accuracy of the data.
What are the BENG indicators included in the report?
The report includes EP1 (energy demand), EP2 (fossil energy use), and EP3 (renewable energy share).
