In terms of the material, economic benefits, environmental protection and industrialization, those characteristics are summarized as follows.(1) Being sturdy, corrosion-resisting, waterproof and insulated, building materials are able to resist bad weather.(2) Their economic results lie in the short constructive cycle so that the cost of reinforced concrete per unit area reduces 20% on year-on-year basis.(3) Their environmental protection rests with the recyclability of materials, less construction waste and less noise in the construction process.(4) Their industrialization is embedded in their modular design and standardized specifications as well as the flexibility and replaceability.展开更多

However, redevelopment directly or indirectly leads to displacement of low-income residents. The new residents would be of a higher socio-economic status than the previous occupants. For controlling this phenomenon, a study about the influence of displacement to the successful of sustainable multi-storey housing development for low-income society has been done with descriptive method, observation and literature study. The result of this study give knowledge that displacement always happened when the quality of building and environment is increase, the location of multi-storey housing is near city center and commercial area. Low income society voluntary displaced their units to middle or high income society, because they are not affordable for paying operational and maintenance costs. The government has to make regulations for controlling displacement on multi-storey housing for low-income society and for the successful of sustainable multi-storey housing development in urban area.展开更多

To address this problem, this study used a mixed-method approach to evaluate the indoor environmental quality performance of 17 green low-income single attached family houses in Brandon, Manitoba, Canada. Questionnaires were administered to occupants to assess their snapshot and long-term satisfaction with the indoor environment. In addition, snapshot measurements were carried out to evaluate the indoor environmental quality factors of thermal comfort, indoor air quality, lighting and acoustics. Occupants’ snapshot satisfaction was categorized into two groups (i.e. satisfied/comfortable or dissatisfied/uncomfortable) and compared with snapshot measurements. The results showed the measured IEQ parameters were well below recommended threshold levels. Further, occupants with higher snapshot satisfaction were generally exposed to relatively lower levels of indoor pollutants. A statistically significant difference was found in PM10 level only between the snapshot satisfied and snapshot dissatisfied groups of occupants. Apparent sound transmission classes were below the standard reference value of 50, suggesting potential problems in noise attenuation within different spaces in each apartment and between apartments. The findings of this study could help governments implement green shadowing for public-housing and also renovate existing houses using the same principles.展开更多

Due to globalization and changes in the world, housing is no longer only a structure that provides sheltering but is also a factor that provides mutual interaction in formation of life style and quality. The elements such as the increase in the effect of consumption preferences and life style on selections, the changes in family structure, and urban structures also influence the residences used and housing preferences. The purpose of this study is to determine the general situation of housing preferences while taking into account the family life style in Turkey and at the same time to make an evaluation based on international publications.展开更多

The set of compared heat energy sources comprised nine different sources. After normalisation (which meant recalculating the impacts into their proportions to the average impact of the kind, experienced by an average European in a year), weighting (which meant attaching arbitrary weights to three aggregate impact categories according to a methodology Eco-indicator 99 E/E) and summation of the weighted results expressed in so-called ecopoints, the coal combustion furnace turned out to have the greatest impact. It was followed by an electric stove and an oil burning furnace. The wood burning furnace and the heat pump had the smallest impact, almost equal in size. Results indicate that in case of renewable energy carriers like wood, straw and pellets, the total environmental hazard factor in 70% and more is derived from the respiratory harmful inorganic emissions. Extending the analysis by a LC assessment of equipment (boilers and pumps) might change the order of technologies.展开更多
