Evaluation of replacement air systems – Avoiding negative pressure problems during cooker hood operation in airtight dwellings

Magazine article, 2023

The present paper summarizes the results of a Swedish technology competition on ventilation in energy-efficient residential buildings. The first stage of the competition was conducted during 2019 - 2020 in collaboration between the trade organizations/networks Svensk Ventilation (svenskventilation.se) and BeBo (The Swedish Energy Agency´s network for residential property owners committed to energy efficiency bebostad.se) with the overall aim of stimulating new and innovative solutions to ventilation problems in energy efficient residential buildings. The problem addressed in this article is linked to the need to supply replacement air in conjunction with operation of the range hood to avoid disturbing under-pressure in the apartment.
