Project 2 · Kaisariani, Edessa

Certified Passive House in Kaisariani, Edessa

Construction supervision, heat-recovery ventilation installation and Blower Door testing of the building envelope.

The project

Designed and verified in detail.

Technical supervision focused on the airtight envelope, window connections and the mechanical ventilation system with heat recovery. The photographic record documents the air-distribution network, critical junctions and final airtightness test.

Heat-recovery ventilation system installation
Air-duct network development and inspection
Airtight window-to-envelope connections
Depressurisation and pressurisation testing at 50 Pa

Blower Door Test

Measured airtightness results

The final test recorded an average n50 value of 0.58 1/h, with 0.57 1/h under depressurisation and 0.59 1/h under pressurisation. The average airflow V50 was 229 m³/h and the air permeability q50 was 1.62 m³/(h·m²).
