Heating and Cooling Performance of Earth-Tube Heat Exchanger in a Mechanical Ventilated Farrowing House

Earth tempering of stable air has attracted great attention as a sustainable air conditioning method in pig houses. At summer time air cooling of income air strongly reduces heat stress and required ventilation rate. At winter time heating costs can be reduced. The effect of air condition using geothermal energy was investigated in a farrowing house. Underneath the foundation of the farrowing house 88 non perforated ribbed tubes （diameter： 20 cm） were piped in a depth of 1.6-2.0 m. Over a period of 12 month following data were recorded at hourly intervals and analyzed： outside air temperature, as well as air temperature in the air supply duct and in the compartments. Incoming air （supply duct） was heated up to 20 ℃ during winter time and in summer time cooled by up to 15 ℃ compared to the outside air temperature. In contrast to the outside air diurnal variation, temperature fluctuations of the incoming air were reduced by 90%. Due to cooling of the incoming air at summer time the stable inside temperature could be limited to maximal 29 ℃（maximum outside temperature was 35℃）. Earth-tube heat exchangers with non perforated ribbed tubes were very efficient for air conditioning in farrowing houses. They were a cost effective supplement for sustainable cooling and heating of farrowing houses.

Assessment of Compliance to Building Energy Efficiency Strategies in the Development of Housing Estates in FCC, Abuja Nigeria

Compliance to local energy efficiency strategies can significantly reduce energy consumption in buildings and promote sustainability. However, Nigeria Building Energy Efficiency Code (BEEC) seems to be just paper work without enforcement or compliance. Assessment of Compliance to Green Building Energy Efficiency Strategies in the Development of Housing Estates in FCC, Abuja Nigeria was carried out. The compliance of estate buildings to BEEC in the study area was assessed;and the aspects of the building energy efficiency strategies with more compliance were determined. Data were mainly from primary sources such as questionnaire survey, interview with key informants and observation. The study population included all estate developers and building construction professionals. Data were gathered from one hundred and fifty (150) building professionals through questionnaire administration. Data collected were analysed using Z score and ANOVA and presented in tables. Results show that only 18% of respondents agreed that building complied with BEEC, and the Z score for positive affirmation is below average score. There is a significant difference in the integration of different energy efficient management strategies in the estates’ construction at 95% confidence level. The integration of measures such as window to wall ratio and window shading’ were significantly higher than other BEEC strategies such as roof insulation and minimal air condition unit (≤EER/COP of 2.8). Thus, the development of estates in FCC Abuja did not achieve energy efficiency.

Open Building as a Design Approach for Adaptability in Chinese Public Housing

Surveys on public housing in Northern China indicated that the common aim of Chinese public housing, which is to provide affordable housing, had been mostly satisfied. However, more than one fourth (29.9%) of the public housing units that were investigated were structurally modified by their occupiers for different layouts. This situation indicated that a fixed plan could not fulfill housing occupiers’ various requirements on spacing layout, and critical awareness had been shown that the adaptability of the public housing units was always ignored. Open Building is well organized and implemented in the field of residential area to increase adaptability and sustainability of dwellings. This paper reviewed the development of residential Open Building and attempted to reveal solutions for the design of adaptability in Chinese public housing. Based on the dwelling unit types, dwelling spaces, living modes and demographic conditions of the public housing units were investigated;and concerning the actual carried out adaptations in the public housing units, this research explored two levels of design and control methods: prototyping unit for possible layouts and flexible partitions for space-function reconfiguration. By adding design values of adaptability in public housing, key aspects showing?the potentials and challenges for the design of public housing were summarized for future reference.

Confucian Moralizing Functions of Vernacular Houses:A Case Study of Vernacular Houses of Dongting East Mountain and West Mountain

Confucian ethics, idea and behavior criterion were embodied in "everything" of life, especially in the building as an important tool for moralizing. Taking a case study on vernacular houses of Dongting East Mountain and West Mountain, this paper reveals the "moderate", "etiquette" and "benevolence" as moral contents in the building's layout, form, space, decoration and so on. The moralizing reflects a subtle way of guidance, as well as diversified and systematic characteristics. Vernacular houses deeply mingled with daily life, had unique influence as physical environment, thus realizing the implementation and manifestation of Confucian moralizing ideas that have been converted to folk customs. In sum, the Confucian moralizing function carried by vernacular houses is the product of institutions and rules, and it is also the manifestation of conscious inheritance of cultural identity.
