Multidisciplinary site management, geodetic precision, and building envelope engineering.
Developers, general contractors, architects, and M&E engineers.

Ventum Engineering works directly with developers, general contractors, and design professionals to deliver fully compliant building envelopes and ventilation installations across Ireland—on time, to spec, and without trade coordination friction.
Mechanical Ventilation with Heat Recovery (MVHR) Design & Installation
Centralised Mechanical Extract Ventilation (cMEV) & Demand-Controlled Systems
Complete Building Envelope Airtightness Installation & Remedial Sealing
Calibrated Airflow Commissioning, Blower Door Testing & Part F Sign-off
Smart, low-energy moisture extraction systems powered by AERECO technology. Zonal sensors automatically modulate air extraction based on relative humidity, keeping running costs minimal and preventing condensation in kitchens and wet rooms.
The gold standard for NZEB and Passive House developments. Our balanced supply-and-extract systems recover up to 90% of outgoing thermal energy, circulating continuous, filtered fresh air in whisper-quiet operation while cutting space heating demand.
We design and install continuous airtight layers using specialist intelligent membranes, tapes, and penetration grommets. From window frame junctions and floor-to-wall interfaces to duct penetrations and blower door testing coordination, we seal buildings to meet strict permeability targets.

We are a multidisciplinary engineering contractor operating across Ireland. Our background bridges precision geodesy, on-site construction management, and building physics.
Because we install both the airtight envelope and the mechanical ventilation system, we eliminate the gap between trades. An MVHR system cannot perform without an airtight structure, and an airtight structure cannot function without planned ventilation. We engineer both disciplines under one roof, guaranteeing full compliance with Irish Building Regulations Part F (2019) and NZEB standards.

LOETB-certified in Nearly Zero Energy Building (NZEB) standards, holding the City & Guilds 'Assured' accreditation. Every system is designed and commissioned in strict accordance with Technical Guidance Document Part F 2019.

Led by professional members of Engineers Ireland, adhering to the highest code of engineering ethics and standards.

Fully accredited by the Passive House Institute (PHI) Darmstadt, bringing world-class, ultra-low energy design precision to Irish residential and commercial projects.
Developers, contractors and M&E engineers across Ireland trust Ventum to deliver compliant ventilation packages on time and to spec.
Ventum installed our MVHR system across 24 units — on time, fully compliant, zero issues at handover.
