BRL9500-MWA-U – National Assessment Guideline for Non-Residential Energy Advice
The BRL9500-MWA-U is a national assessment guideline (Nationale beoordelingsrichtlijn) established by the CCvD of Stichting InstallQ in the Netherlands. Binding as of July 1, 2023, and accepted by the Dutch Accreditation Council (Raad voor Accreditatie), this document provides the framework for the InstallQ process certificate required to issue a customized energy advice (Maatwerkadvies) for non-residential buildings (Utiliteitsgebouwen). It sits within the broader energy performance regulatory framework, replacing previous versions such as BRL9500-04.
The scope of this guideline covers the certification of companies providing energy-saving advice for existing non-residential structures. Unlike standard energy performance reports which use standardized conditions, a Maatwerkadvies is tailored to actual building usage and local climate conditions. The document outlines specific regulatory requirements based on the NTA 8800 determination method and includes mandatory technical standards from ISSO-publication 75.1 and ISSO-publication 75.2. Key structural elements of the guideline include requirements for the advice itself (Chapter 3), certified activities (Chapter 4), and internal quality monitoring (Chapter 6).
This document details the professional competencies required for an EP-maatwerkadviseur U and the administrative procedures for registering advice in the national database managed by RVO (Rijksdienst voor Ondernemend Nederland). It defines the criteria for audits, inspections, and the maintenance of project dossiers.
Objective and Scope of Certification
Certification according to BRL9500-MWA-U is designed to ensure the quality of energy-saving recommendations for non-residential buildings. The primary objective is to provide building owners with concrete, cost-effective measures to achieve energy saving goals based on their specific context.
- Maatwerkadvies U: An energetic improvement advice for non-residential buildings where realistic technical measures are balanced against the owner's investment goals.
- Nulmeting: A baseline measurement performed according to BRL9500-U which may be conducted simultaneously with the customized advice for financing or subsidy purposes.
- Target Audience: Building owners, developers, and financiers requiring reliable, reproducible energy saving outcomes.
Technical Requirements for the Maatwerkadvies
Section 3 defines the mandatory components of a certified advice report. The advisor must use software attested under BRL9501 and follow the calculation rules defined in NTA 8800 while applying specific deviations allowed for actual use scenarios.
- Fitting Procedure: Aligning input parameters with measured energy consumption data to accurately reflect the building's current thermal and technical performance.
- Measure Packages: The report must include one or more packages of technical measures, analyzed for cost-benefit (Payback period, Net Present Value).
- Maintenance Alignment: If a MJOP (Meerjarenonderhoudsplan) exists, measures must be coordinated with planned natural maintenance cycles.
- Calculation Parameters: Factors such as setpoint temperatures, lighting hours, and specific user profiles may be adjusted as 'Free input' (Vrije invoer) when following the fitting protocol.
Competencies and Certified Activities
Chapter 4 specifies the activities that a certified EP-maatwerkadviseur U must perform to validly register a Maatwerkadvies in the national EP Online database.
- Intake and Informed Consent: Documenting the owner's goals and informing them about data registration and the possibility of control audits.
- Recording (Opname): Data collection based on ISSO-publication 75.1 or ISSO-publication 75.2, involving on-site observations or verified existing energy performance data.
- Registration: The final advice must be uploaded to the national database managed by RVO; advice requested by a tenant cannot be officially registered.
- Professional Skills: Advisors must hold valid evidence of professional competence for both energy performance assessment and customized advice for non-residential buildings.
Quality Assurance and Monitoring
Certified companies must maintain an internal quality management system, typically documented in a Kwaliteitshandboek. This system is subject to both internal and external surveillance.
- Internal Audits: Conducted at least once a year, including a check on at least 5% of registered customized advice reports per advisor.
- Project Records: All relevant project data, including intake forms, calculation files, and correspondence, must be preserved for a minimum of 10 years after completion.
- External Audits: Certification bodies perform organization-oriented audits and project-specific inspections to verify compliance with BRL9500-MWA-U requirements.
Frequently Asked Questions
What is the difference between an Energy Label and a Maatwerkadvies?
An Energy Label reflects energy performance under standard usage conditions, while a Maatwerkadvies provides practical advice tailored to actual building use, occupant behavior, and local climate factors.
Is it mandatory to use specific software for BRL9500-MWA-U?
Yes, calculations must be performed using software that is attested based on BRL9501 and specifically designed for the EP-MWA-U calculation method.
What is 'Fitting' in the context of this energy advice?
Fitting is the process of adjusting model input parameters based on measured energy consumption data to ensure the calculation model matches the building's actual energy usage.
Can a tenant have a Maatwerkadvies registered in the national database?
No, according to section 4.2.8, a Maatwerkadvies commissioned by a tenant may not be registered in the national database managed by RVO.
How long must the certificate holder store project dossiers?
The certificate holder is required to store the project dossier and the computer data files used to generate the advice for at least 10 years after the assignment's completion.
What qualifications does a BRL9500-MWA-U advisor need?
An advisor must hold valid professional competence evidence for 'EP-maatwerkadviseur U' and, depending on the recording level, 'EP-U/B' or 'EP-U/D' competence.
