Humidity buffering effect of the hygroscopic materials applied in a tightly controlled hygrothermal interior and its impact on energy consumption in historical buildings

Historical buildings with masonry construction are characterised with large thermal mass and hygroscopic features and their ability to moderate extrem weather conditions is well known. The effects of thermal mass on stabilising indoor thermal condition and reducing the sensible loads have been well known and models to simulate the mechanism are widely available and used in various design stages and system options. But mass transfer and moisture buffering due to the use of hygroscopic materials is much less examined as moisture control is complicated and insignificant in most buildings where human comfort is the major concern.

In archives, galleries and museums, it is essential to maintain the stability of the temperature and relative humidity of the indoor air to a narrow psychrometric zone for conservation of the artefacts in display. This tight control of indoor environnment is very energy intensive.

This project is, first, to develop a modelling module to integrating the thermal and moiture coupled model and calibrating the model with a purposely designed test, and second, to use the model to develop a set of optimal operation options for the control system through modelling parametric studies. This work is built on the previous studies in collaboration with University of Edinburgh and National Galleries of Scotland, in particular, to join in an on-going project investigating the control perfermance and energy efficiency in two of Scottish galleries. The outcomes of this research are expected to help assessing the energy performance as well as renovation solutions for gallery and museum housed in old buildings and develop optimal and balanced solution for energy efficiency and environment quality.
