I like the ancient pattern, where and instead of one＇s title one tells the name of one＇s mentor. Three mentors shaped my professional life. The first one was in Warsaw, Poland, Prof. Bohdan Lewicki, whose books on concrete panels were translated in many languages. One day, after his class, he told me：＂We need to evaluate hygrothermal performance of an experimental building with no-fine concrete,--if you would like to do it, I will provide you with aU the money needed. From this day on, I have been learning Building Physics. My second mentor was Prof. Lars Eric Nevander in Lund, Sweden, one of the three Swedish professors who in 1972 introduced limit states method into the field of durability assessment, exactly 40 years before the first ISO standard did so. Lars Eric taught me that progress in construction depends on how strong is the continuum between industrial and academic domains in Building Physics.

1. Preamble ReaLizing that in design of Zero Net Energy （ZNE） projects, the integration includes not only technology itself, and also the expansion of technology＇s use and cottaboration producing a collective vision by many people of similar minds. Today we see hundreds of American webinars where various companies are teaching the use of their products, however a very few teach principles that govern the selection of the products.

When a historic façade needs to be preserved or when the seismic considerations favor use of a concrete wall system and fire considerations limit exterior thermal insulation,one needs to use interior thermal insulation *** thermal insulation systems are less effective than the exterior systems and will not reduce the effect of thermal *** they may be successfully used and,in many instances,are recommended as a complement to the exterior *** paper presents one of these *** is focused on the most successful applications of capillary active,dynamic interior thermal *** happens when such insulation is integrated with heating,cooling and ventilation,air conditioning(HVAC)*** with a pioneering work of the Technical University in Dresden in development of capillary active interior insulations,we propose a next generation,namely,a bio-fiber thermal *** completing the review,this paper proposes a concept of a joint research project to be undertaken by partners from the US(where improvement of indoor climate in exposed coastal areas is needed),China(indoor climate in non-air conditioned concrete buildings is an issue),and Germany(where the bio-fiber technology has been developed).

建筑材料处于高湿环境中,即在有液态水环境下,如地下建筑,被雨水冲刷的外围护结构等,材料的吸水性能及干燥能力的研究对控制和解决建筑热湿引起耐久性,保温性和与湿相关问题有至关重要的作用,而材料的吸水性能及干燥能力均与材料表面孔隙大小,面积百分数和分形维数相关。本文将采用盒计数维数法及德莱塞理论分析采用进行图像处理后的灰泥SEM图。结果表明灰泥样品不同位置的表面孔隙大小分布,面积百分数及分形维数均不同。其中表面微孔较多且分形维数较大一侧接触水的灰泥样品的吸水系数为0.10107 kg/(m2.s0.5),表面微孔较少且分形维数较小一侧接触水的灰泥样品的吸水系数为0.04652 kg/(m2.s0.5),即对于多孔材料-灰泥其吸水表面微孔越多,分形维数越大,其吸水系数相对越大,吸水能力越强。
