Nevertheless, the growing number of population falling under poverty put more demand on low cost housing options. The goal of the research was to find ways of rationalizing the cost and determine the appropriate standards and models that achieve an acceptable equation between cost and performance, and that during design and construction phases. The study follows the method of investigation and analysis to get factors that reduce the cost of the house construction for poor families by means of the concept of standardization in traditional （popular） buildings system. The research confirms that the traditional system has many advantages that could strengthen towards development a low-cost building system by applying the principles of standardization through architectural, structural and electro-mechanical considerations of design. Research recommends taking on studies for low cost building system through comprehensive analytical study of local building experiences.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

One of the strategies for improving energy performance of buildings is the installation of microgeneration systems. This will enable Portugal to meet the goal regarding the share of renewable sources on gross final energy consumption imposed by the European Commission climate change and energy package for 2020. The analysis of four different micro-generation systems will take into account the local availability of renewable resources and market technologies and the new Portuguese law concerning microgeneration to promote renewable energy sources in households. The Portuguese microgeneration legal framework is also highlighted.展开更多

The DGT （dwelling-garret type） is an important vernacular study case. The DGT is a historic building of 18th century, located in the core of Lebusha Village, Municipality of Peja, an architectural construction characterized by two concentric volumes at rectangular layout, very dynamic at horizontal composition, obtained by the movement of two differently constructional materials volumes, stone masonry and timber assembly, and covered with roof clay tiles. In view of its esthetic and artistic values, its important role at developing chain of Kosovo＇s rural dwellings typology, and its method of construction, the building should be listed as a monument under state protection. Hence, immediate protection interventions, such as conservation of wooden and stone envelope, improvement of walls and finish works, and drainage infrastructure, are considered as the minimum requirement.展开更多
