The Role of Carbon Dioxide in Ventilation and IAQ Evaluation: 40 years of AIVC | 2019 | English | 4 pp
The purpose of this summary is to review Air Infiltration and Ventilation Centre activities, as reflected in its publications, related to indoor carbon dioxide over the 40 years that have transpired since its creation.
This extended summary is a part of a more extensive summary (technote to be published) that compiles a number of AIVC publications that deal with ventilation and health in relation to moisture in air, and the development over time.
Japan is characterized by high humidity in summer and low humidity in winter. Therefore, summer is in a climatic condition where mold is easy to grow, and in fact, mold damage is occurring.
Due to the increasingly stringent energy efficiency requirements, timber frame houses are becoming more and more popular across Europe.
A smart ventilation system is generally equipped with a range of sensors. The data – or data derived from it - collected by these sensors can be used by both building owners, occupants and managers.
ByggaF is a methodology for including moisture safety in the construction process that was developed and presented in 2007.
Analysis of the Effects of Ventilation Method on Indoor Humidity Distribution and Condensation by CFD method | 2019 | English | 8 pp
People spend 70% -90% of their time indoors. Indoor air quality and human body’s health have a close relationship. With the advance of society, user comfort requirements for thermal environment are rising.
