“…WUFI Plus, developed by Fraunhofer Institute for Building Physics, is based on the HMT model defined by Künzel in [17]. The whole building model has been validated several times [18,19], compared with other software tools [20,21] and accepted as a valid comparison tool to evaluate new materials [22] or simplified calculation methods [23]. The coupling of the wall HMT model and the building model allows to evaluate the effects of liquid water (driving rain or from other sources) and vapour concentration (from internal loads) on the energy balance of the whole building.…”

Transient building energy simulations are powerful design tools that are used for the estimation of HVAC demands and internal hygrothermal conditions of buildings. These calculations are commonly performed using a (often dated) typical meteorological year, generated from past weather measurements excluding extreme weather conditions. In this paper the results of multiyear building simulations performed considering coupled Heat and Moisture Transfer (HMT) in building materials are presented. A simple building is simulated in the city of Udine (Italy) using a weather record of 25 years. Performing a multiyear simulation allows to obtain a distribution of results instead of a single number for each variable. The small therm climate change is shown to influence thermal demands and internal conditions with multiyear effects. From this results it is possible to conclude that weather records used as weather files have to be periodically updated and that moisture transfer is relevant in energy and comfort calculations. Moreover, the simulations are performed using the software WUFI Plus and it is shown that using a thermal model for the building envelope could be a non negligible simplification for the comfort related calculations.

“…For the modelling of room 9, IDA ICE was extended with the HMWall model, that implements a one-dimensional heat air and moisture transfer model across porous materials. The HMWall model was meticulously tested by the authors using exercises at increasing complexity and the preliminary results are reported in (Frasca et al, 2018). Our purpose was to calibrate the building envelope when the HVAC system was not in operation.…”

The indoor climate conditions being suitable for the conservation of cultural heritage can be conflicting with energy saving and thermal comfort. Moreover, the moisture dynamics have not been studied enough in the simulation of the indoor environment, even though its interaction with artworks is crucial in deterioration phenomena. This research aims at defining a strategy, based on experimental data and dynamic simulation of hygrothermal behaviour, in order to design a HVAC system able to simultaneously satisfy conservation, thermal comfort and energy requirements. A weighted function for the multi-objective optimization has been proposed and effectively used to pinpoint the combination of temperature and relative humidity set-points.
