Mechanical Ventilation CAD Blocks DWG – MVHR ERV HRV System Layout | Free Download

Description

Our Mechanical Ventilation CAD Blocks Download Center library covers heat recovery ventilation systems for low-energy and Passivhaus buildings. Included are MVHR (Mechanical Ventilation with Heat Recovery) unit footprints, duct distribution layout templates, supply and extract terminal positions, and acoustic attenuator locations.

Duct sizes and terminal quantities are indicative for 100–150 m² dwelling air flow rates. System layouts follow CIBSE AM13 (Mixed Mode), PHI (Passive House Institute) MVHR planning guidance, and NHBC Part 6 ventilation requirements.

AutoCAD 2010 and above. Valuable for Passivhaus designers, low-energy building architects, M&E engineers, and self-builders planning mechanical ventilation systems for new or renovated homes.
