NSAI Ventilation Validation Certified Third-Party Service
Irish Energy Assessors now offer third-party validation services under the NSAI Ventilation Validation Scheme.
We certify that your residential ventilation installation complies with TGD F (2019) of the Irish Building Regulations.
Under NSAI registration, our qualified assessors verify that systems are installed, balanced, and commissioned per I.S. EN 14134:2019 Ventilation for Buildings – Performance Testing and Installation Checks of Residential Ventilation Systems. We ensure compliance with F1 of Technical Guidance Document F, confirming adequate airflow rates, system integrity, and full documentation for BER certification.
Air Tightness Testing Residential & Commercial — Blower Door Testing to I.S. EN ISO 9972
Irish Energy Assessors provides independent blower door air tightness testing for dwellings and non-domestic buildings nationwide. Our reports support Part L compliance and BER documentation, with clear pass/fail outcomes and practical guidance to reach target permeability.
Tests are performed to I.S. EN ISO 9972 using calibrated equipment. We complete depressurisation/pressurisation runs, verify envelope area calculations, and issue a certificate detailing air permeability at 50 Pa (m³/(h·m²) @50 Pa) and, where required, air changes per hour (n₅₀). Optional diagnostic smoke and thermography can be included to pinpoint leakage paths before retest.
- Residential: New builds, extensions, and deep retrofits with Part L targets.
- Commercial/Non-Domestic: Offices, schools, healthcare, industrial units and shells.
- Traceable calibration, photo log, and clear remediation actions when needed.

Request a Compliance CheckSound Insulation Testing Part E Compliance for Attached Dwellings
Irish Energy Assessors carry out field tests for airborne and impact sound insulation between attached dwellings to demonstrate compliance with Building Regulations Part E. Our measurements are performed using class 1 instrumentation and reported in a format accepted by Assigned Certifiers and BCAs.
Testing is conducted in accordance with EN ISO 16283-1 (airborne) and EN ISO 16283-2 (impact). To satisfy Part E performance: DnT,w ≥ 53 dB (airborne) and L’nT,w ≤ 58 dB (impact) across the separating element. We advise on test scheduling, sampling frequency, and remedial actions if early results underperform.
