Heat Recovery in a Passive House–A Technical Study
Adrian Liviu Olteanu* and Horia Petran
ABSTRACT
This presentation highlights the energy efficiency of buildings known as "Passive Houses," comparing the energy performance of a conventionally built house with that of a house constructed according to the standards set by the Passive House Institute.
This study details the energy and functional analysis of a heat recovery ventilation (HRV) system in a passive house located in Găești, Dâmbovița County. The performance of the HRV system was evaluated under real usage conditions, focusing on heat loss, energy consumption, and indoor air quality.
In the final part of the article, using graphs and technical diagrams, we demonstrate how the implementation of a high- performance HRV system in a passive house significantly reduces energy losses and contributes to a healthy indoor climate. This study confirms the benefits of using HRV systems in the temperate climate of the Găești region, supporting the broader adoption of these solutions in energy-efficient homes.
