Moisture transfer in hygroscopic materials and energy exchangers for buildings

。对建筑的研究是非常重要的，因为加拿大人90%以上的时间都花在建筑上，建筑部门占加拿大能源消耗的30%以上。因此，为居住者提供良好的室内气候和空气质量（即健康建筑），同时消耗最少的能源对一个健康、繁荣和可持续发展的国家至关重要。一个重要的，但往往被忽视的室内环境参数是湿度，因此室内湿度通常被认为是一个成功的设计的小重要性，因为温度更容易感知，量化和控制。然而，研究表明，室内相对湿度可以显著影响：(i)热舒适，（ii）对空气质量的感知，（iii）居住者健康，（iv）建筑材料的耐久性，(v)材料排放和（vi）能源消耗。事实上，在加拿大和其他类似寒冷气候的国家，潮湿是导致建筑物倒塌和室内空气质量差的主要原因之一。由于温度和湿度在人类对空气质量的感知中起着重要作用，因此无论是否受到污染，炎热潮湿的空气都会被感知为质量差（或污染物浓度高）。室内环境的质量尤其重要，因为它与居住者的健康和福祉密切相关。

. Research on buildings is very important because Canadians spend over 90% of their time in buildings and the building sector in Canada accounts for over 30% of energy consumption. Therefore, buildings that provide occupants with a good indoor climate and air quality (i.e., healthy buildings), while consuming minimal energy are important for a healthy, prosperous and sustainable nation. An important, but often neglected, indoor environmental parameter is humidity, thus indoor humidity is often considered to be of small importance for a successful design because temperature is easier to sense, quantify and control. Nevertheless, research has shown that the indoor relative humidity can significantly affect: (i) thermal comfort, (ii) the perception of air quality, (iii) occupant health, (iv) the durability of building materials, (v) material emissions and (vi) energy consumption. In fact, moisture is one of the leading causes of building failure and poor indoor air quality in Canada and countries with similar cold climates. Since temperature and humidity play an important role in the human perception of air quality, air that is hot and humid will be perceived to have a poor quality (or high concentration of contaminants) regardless of whether it is polluted or not. The quality of the indoor environment is especially important because it is strongly linked to the health and well being of occupants.
