林芝地区传统民居冬季室内热环境评价与分析

西藏林芝地区传统民居是在高原寒冷气候条件下形成的居住形态。本文选取林芝地区传统民居和现代民居在冬季进行室内外温湿度,风速等热环境参数测量,并对民居的建筑热工性能及室内热环境进行定量分析与对比,同时通过热舒适指标对传统建筑热舒适进行评价。结果表明传统民居外围护结构具有较好的热工性能,通过被动式的方式降低室外气候对室内的影响,但室内不能达到热舒适标准,需要通过采暖和合理的功能安排实现室内热舒适。

传统生土民居生态节能性分析及技术改造

传统生土民居是我国农村地区典型的居住形式之一,目前仍大量存在,但其室内采光差、热舒适性低等问题尤为突出。本文选取夏热冬冷地区典型生土建筑,利用Ecotect软件进行了室内光环境及热环境的模拟分析,针对建筑节能的薄弱环节提出技术改造措施。模拟结果显示适当提高窗墙比、墙面反射率及增设明瓦能使各房间的自然采光时间提高20%,而围护结构热工性能改造和被动式太阳能的利用使建筑冬季室内温度的升高与夏季室内温度的降低较为显著,可有效提高室内热环境质量。本研究为我国传统生土建筑的室内环境改善提供量化依据与理论参考。

巴渝地区夯土民居室内热环境

传统民居的传统生态建造经验与价值已得到广泛认可,巴渝地区因特殊的地形与气候,传统民居在热环境的营造上有自身的特点。以重庆江津区龙塘村夯土民居为研究对象,以实地测量的冬季室内热工参数为基础,运用软件模拟分析,对民居全年室内热环境进行评价,发现夯土墙对改善夏季热环境更为有利,夯土民居冬季室内热环境远比夏季差;民居建筑中阁楼空间在调节室内热环境方面作用显著,具有冬季保温,夏季隔热的作用。     

民居建筑屋顶热工性能研究

节能是现代建筑的发展方向,屋顶能耗在围护结构总能耗中所占比重较大,因此屋面保温隔热性能的优劣对建筑节能效果的影响是显而易见的.在此,以皖南民居为例,对民居中三类屋顶的热工性能进行了定量实测与分析,认为民居建筑中采用不同材料及构造方式的屋顶的热工性能差别很大,因此改善民居热舒适度应该重视对屋顶的材料及构造措施的选择.

Place-Making in Megaprojects in Melbourne

This article analyses state-led place-making practices in Melbourne. The two levels of government that influence planning in Melbourne make much of the city as ‘culturally vibrant’ and ‘creative’, and have incorporated creative city-inspired place-making principles into many layers of the planning system. An examination of the development of two mixed-use megaprojects in central Melbourne reveals however that ideals of culturally engaging public places, and indeed of creative landscapes for middle-class consumption, wither in the face of more basic imperatives for economic development. In these case studies the ‘creative city’, no matter how the idea is interpreted, has little traction either as a set of inclusive place-making principles or as a gentrification strategy. The article concludes that the creative city-inspired place-making objectives in the planning system at both state and local levels are ambiguous in their overall intents and completely unsupported by statutory controls. Such place-making objectives as are realised are the compromised results of the interplay of uncoordinated decisions, delivered at the pleasure of the developer.     

Pathogens in septage in Vietnam

Septage is widely acknowledged as a major source of infectious pathogens while disposal of septage, and the operation and maintenance of septic tanks, is not regulated in many developing countries. Twenty untreated septage and septage sludge samples were taken from Can Tho City, Vietnam to examine their pathogen content, and indicator micro-organisms. Escherichia coli and Enterococcus spp. were detected in all samples, regardless of sludge storage time. Phages were detected in 80% of samples. Salmonella spp. were detected in 70% of the untreated septage and 60% of septage sludge samples. Concentrations of phages and bacteria tested in septage sludge after many years of tank storage were much higher than the expected levels. Helminth ova were present in 95% of untreated septage samples with an average of 450 ova l^− 1, and were detected in all septage sludge samples with an average of 16,000 ova l^− 1. Twelve varieties of helminth ova were identified. More helminth ova varieties in higher concentrations were found in septage than those reported from stool samples. The varieties' frequency ranged from 10% to 50% and Ascaris lumbricoides predominated. Results show that pathogens and indicator micro-organisms, especially helminth ova, accumulate in sludge. Thus helminth ova should be considered when septage sludge is treated and used for agriculture. Proper health protection measures must be applied for people handling septage.

Variation in property taxation in Tulsa

Conclusions It may be reasonably concluded from this study that the range of variation in these ratios of assessed to actual value are of a reasonable size for the great majority of cases. The frequency distribution of these sample ratios was not normal, however, as was assumed a process of this type would produce. On the other hand, the failure of the regression analysis to identify any significant variables which would explain these variations would tend to re-enforce the assumption that the fluctuations were indeed of a random nature.To sum it up in one paragraph, aside from a few extreme cases, the assessing process appears to give estimates which are more consistent than would be expected under the assumption that any errors would be of a random nature, but the regression analysis was unable to isolate any particular socioeconomic characteristics which would explain the variation which was present.Financial support for this research project was furnished by the University of Tulsa.
