夏热冬冷地区居住建筑夏季人员开窗行为实测与建模研究

开关窗是建筑使用者控制室内热环境和改善室内空气品质最直接且简单的手段,同时对建筑节能也有重要影响,因此对人员开关窗行为的定量化描述是非常必要的。本研究通过对夏热冬冷地区—?—自贡市7户住宅夏季人员开窗行为的实际监测,得到以下结论：发现实测样本中存在三种明显差异的典型开窗行为,分别是习惯性开窗型、高强度开窗型和习惯性关窗型;对非环境因素分析得出,一天中不同时段以及家庭成员吸烟与否对开窗概率影响显著,而是否为工作日以及住户所在楼层对开窗概率无明显影夏热冬冷地区居住建筑夏季人员开窗行为实测与建模研究 *刘奕巧　王新如　崔　颖　魏　绅　潘　嵩　LIU Yiqiao, WANG Xinru, CUI Ying, WEI Shen, PAN SongMeasurement and Modelling of Occupants’ Window Opening Behavior in ResidentialBuildings in the Hot Summer and Cold Winter Regions in Summer中图分类号 TU228文献标识码 B文 章 编 号 2095-6304（2021）05-15-09作者简介刘奕巧： 吉林建筑大学寒地建筑综合节能教育部重点实验室,马来亚大学机械工程学院,博士研究生王新如（ 通讯作者）：天津商业大学机械工程学院,讲师,xinru5263@ticu.edu.cn崔　颖：宝武清洁能源武汉有限公司魏　绅： 伦敦大学学院巴特莱特可持续建筑学院,副教授潘　嵩： 吉林建筑大学寒地建筑综合节能教育部重点实验室,北京工业大学绿色建筑环境与节能技术重点实验室,教授*寒地建筑综合节能教育部重点实验室开放课题项目;河北省国际科技合作基地（20594501D）;“十三五”国家重点研发计划(2017YFC0702200)响;对于环境因素而言,当室外温度超过32 ℃,开窗概率开始降低,空调开启比例升高;室外温度超过37 ℃,空调开启比例达到100%,但开窗比例仍有11.1%;建立了基于二元逻辑回归的夏季高强度开窗行为预测模型,模型的预测准确率达到了86%,而室外温度是该模型最为重要的预测因子。本文的研究成果可以用于细化能耗模拟软件及室内空气品质评价软件对该类型住宅建筑开窗行为特征的描述,对住宅建筑节能设计、运行、改造以及住宅室内空气品质和热舒适研究均有一定程度的参考意义。     

Interactions: Dialogues on Body,Protections and Derivatives

Could kinetic clothing be the next big thing? A collaboration between Dutch fashion designer Iris van Herpen and Italy-based architect and educator Niccolò Casas has produced a series of dresses that blur the boundaries between the body and the space around it. Casas explains how they have fused handcraft with technology, using 3D printing, mass customisation techniques, and morpho-dynamic simulations, among other means, to produce couture pieces that react to bodily movement in extraordinary new ways.

Antioxidative activity of summer savory (Satureja hortensis L.) and rosemary (Rosmarinus officinalis L.) in minced, cooked pork meat

The sensory intensity measured as theabsolute threshold value of spice andrecognition of spice was evaluated for summer savory and rosemary in meat balls. The values forabsolute threshold value of spice were found to be significantly lower for rosemary than for summer savory. The antioxidative activity of the spices was analysed in two accelerated model systems and in a storage experiment. In one of the model systems, oxidation was accelerated by heat and by an elevated pressure of oxygen. Both spices significantly improved the oxidative stability of the meat balls in this model system. In the second model system metal catalyst oxidation in a meat slurry was used and a reduction in the oxidative processes in samples containing the spices was again shown. In both model systems a slightly higher antioxidative activity was seen for rosemary compared to summer savory. In the storage experiment, the spices were added at a sensorially acceptable level and the heat-treated meat balls were stored at 5°C. A significant reduction in the development of warmed-over flavour (WOF) caused by the addition of spices was measured by a reduction in 2-thiobarbituricacid-reactivesubstances (TBARS) and in hexanal. A reduction in TBARS of approximately 30% in meat balls containing added spices was seen independently of packaging in 1% oxygen or in atmospheric air and the reduction (30%) was constant throughout the storage period.     

Will energy regulations in the Gulf States make buildings more comfortable – A scoping study of residential buildings

Building envelope impacts upon energy consumption and indoor environment. The relationship between envelope components and indoor environment has become increasingly important, especially with the new emphasis on visual comfort, thermal comfort and indoor air quality. This paper examines the interaction between occupant thermal comfort and envelope component regulations in the Gulf States. The country chosen for this study is the Kingdom of Bahrain, the smallest country in the Gulf region. Simulation results and comparative studies were employed to investigate the impact of the current envelope component regulations on the internal environment. The paper focuses on residential buildings and concludes that the envelope component regulations contribute positively to the internal thermal performance. Although these envelope components are not generally the primary elements that impact upon internal thermal comfort there are circumstances when the components become very warm and occupants positioned close to them will experience discomfort. This paper shows that the thermal insulation regulation makes a small impact on thermal comfort, whereas the window regulation, particularly glazing, is more influential and that for most window areas, solar impacts are generally large.
