“…The higher the moisture content integral, the worst moisture conditions in the construction. Juráš and Žilinský [46] followed the same method to determine a hygrothermal reference year for Bratislava, Slovenia. A total of two walls were considered: aerated clay brick wall with/without an external thermal insulation composite system made of expanded polystyrene insulation.…”

Hygrothermal simulations have become essential for sustainable and resilient building design because moisture is the major cause of problems in buildings. Appropriate meteorological input data are important to obtain meaningful simulation results. Therefore, this article reviews different methods to create Hygrothermal Reference Years (HRY) as severe or average climate inputs. The current standards define HRYs solely based on outdoor temperature, although moisture problems are caused by a combination of climate parameters, including driving rain and other loads. Therefore, there are also methods considering several impact parameters. The existing methods can be classified into two categories: construction-independent and construction-dependent methods. The former determines HRY based on a weather data analysis and is useful for large-scale parametric studies comprising many climatic parameters acting on buildings. The latter is based in addition to computer simulations to verify the HRY also in the context of specific construction types. It is a more comprehensive approach since the moisture responses of constructions are the decisive outcome for performance predictions. The advantages and disadvantages of the different methods are summarized and compared. Lastly, further research questions and simplifications aimed at practitioners are pointed out to arrive at reliable hygrothermal building performance predictions.

The standard weather station network, belonging to the national weather forecast service, cannot satisfy the requirements of advanced simulation tools because of the network density, time interval of recording, collections of measured values or availability of measured data and its price. Due to the outdoor climate change, urban heat islands and advance in research it is vital to obtain precise data sets for the measured location. Since 2014, also the experimental weather station, which continuously records the wind flow, air temperature, humidity, solar radiation, rain and atmospheric air pressure, is a part of University of Zilina campus.In this paper, measured values of selected climate parameters are analyzed in terms of raw data and also in the case study of two wall types – traditional masonry brick wall and lightweight wooden-frame wall. Behavior of these walls is simulated by the impact of a non-steady state with use of WUFI Pro software. The impact on the hygro-thermal regime of walls – water content, simulated under various boundary conditions, is analyzed and the differences between measured years are quantified.
