TL;DR: In this paper, the demands on durability, energy balance, and energy balance of buildings are discussed, and several biological processes causing aging and damage to buildings are identified, such as natural aging of materials and excessive moisture.

TL;DR: In this paper, the authors focused on the relation between the airtightness of a building envelope, infiltration, and energy use of a typical modern Finnish detached house in the cold climate of Finland.

TL;DR: It is shown that a high concentration of CO2 in indoor air seem to be one parameter causing physiological effects, which can decrease the facility user's functional ability, and the correct amount of ventilation with relation to the number of people using the facility, functional air distribution, and regular breaks can counteract the decrease in functional ability.

TL;DR: Ojanen et al. as mentioned in this paper presented the latest findings of mold growth and the modeling of these factors on different materials, such as pine and spruce sapwood, by using the dynamic temperature and relative humidity histories of the subjected material surfaces.

TL;DR: In this paper, the accuracy of hygrothermal models simulating Nordic climatic conditions from autumn to spring was tested by comparing the results of laboratory tests to determine the heat and moisture performance of timber-framed external wall structures.
