Since 1947, apartment buildings have made their apparition in the Kosovar city landscape. Different aspects have been highlighted by this extensive research: the different types of architecture and their respective characteristics, the modifications made to them throughout the years and the factors, which contributed to these modifications. These buildings have been divided into two categories, the older buildings built by the public sector from 1947 until 1999 and the recent ones built from 1999 until the present time by the private sector.

Analytical and comparative methods have been used to conduct this research. The results revealed that the living area in apartment buildings built after 1999 has been reduced compared to those built earlier, which implies a general trend of decrease of habitable living space. In addition to this, a change worth mentioning in the functionality of these apartment buildings has been noticed. A survey sent to Kosovar citizens was used in order to obtain their opinions on this subject.

Abstract

Nowadays, the problem of energy poverty occurs more and more frequently and its solution is a serious and urgent task. Energy poverty is closely related to the poor energy performance of residential stocks. Energy poverty is simultaneously an energetic and social question, due to involving households having bad energetic parameters. Because of bad efficiency, the energy costs are highly related to earnings. It is not able to enhance the energy efficiency of buildings. Financial supports for endangered layers should contain measures to increase energy efficiency and decrease energy consumption. However, the concept of energy poverty is applied to social groups, like families or communities. In this paper, we extended the concept of energy poverty to SME (small- and medium-sized enterprises). The paper introduces the concept and the risk of energy poverty and the technology of measuring those risks.

Recently, it has become extremely important to reduce the heating energy demand and the CO2 emission of buildings. This reduction can easily be achieved by insulating the shell of buildings. By thermal insulation not only the heating energy demand can be reduced but also higher thermal efficiency can be reached. Therefore, measurements, calculations and simulations are carried out on the energy efficiency of buildings. Furthermore, the combination of methods is of great importance. Combination of experiments with building simulations solution can make design practices and sizing processes easier in the investigation of building performance. The purpose of this article is to demonstrate how the energy balance of a building can be changed in function of the wet building envelope in the Central European Region. A real and available building (old family house) was tested and it was placed (hypothetically) in three different countries (Austria, Hungary and Slovakia). In this study two types of load-bearing structures (brick and concrete) covered with four different types of insulations (mineral wool, expanded polystyrene, graphite-doped expanded polystyrene, and extruded polystyrene) were tested. The change in the heating energy of the building in three different countries by the function of measured water contents of the thermal insulators was simulated by CASAnova simulation software.

Buildings are the largest consumers of energy, accounting for nearly 40% of all energy used. Therefore, an effective method of reducing energy consumption is to create and design more efficient buildings. In this paper details of a sustainable and green building design for a small residential home are presented. This design is unique in that it is built to Passive house standards, and using shipping containers. The structure will use four 20 ft. (6.1 m) high and one 40 ft. (12.2 m) high cube containers, with the four 20 ft. (6.1 m) making up the main floor and the 40 ft. (12.2 m) forming the second floor. The size is a modest 820 sq. ft. (76.2 m2) designed for a family with one or two children.

The goal for the building is to be as self-sufficient as possible which makes it ideally suited to an ‘off-grid’ rural setting. However, it can be adapted to be ‘on-grid’ as well. Solar energy will provide all the electricity needs through a photovoltaic battery system, and warm water with a solar water heater. The site will be water neutral by utilising rainwater harvesting and on site waste water treatment. The results from energy modelling, using HOT2000, are presented, as well as an in-depth analysis on different insulation types and strategies. Finally, a cost estimate exercise is conducted and results compared to other passive houses and traditional code compliance buildings.

Abstract

Sida hermephrodita or Virginia mallow is a perspective perennial herb in the Malvaceae family able to yield a biomass crop through the last two decades. Additionally, the plants have a lot of uses and benefits for instance it can be used as a fodder crop, honey crop, ornamental plant in public gardens. It has favourable features for example fast growing and resistance against the disease and climatic fluctuations, etc. Since Sida is in the beginning phase of domestication, it has a serious disadvantage: the low and slow germination as a big part of wild plants. Due to the expressly low germination percent, the need of seed showing of driller should tenfold 200 thousand seeds/acre instead of 10–20 thousand, which is not available and expensive. Therefore the practical purpose of our research of seed physiology was to increase the seed germination percent in the available, basically wild Sida population. In the first stage of our experiments we examined two factors relating to seed germination percent and seed germination power during our research: the influence of hot water treatment and the effect of exogenous or endogenous infection of seeds. However, in our germination tests, utilizing the scarified seeds with hot water (65, 80 and 95 °C), from 29.3% to 46% germinated from those samples, which were collected from the population of S. hermaphrodita in Debrecen. The average germination for all season was 5–10% without treatment and rinsed using hot water up to almost 50%. When applying physically scarified use, the oldest seeds showed the best germination (46%) after the hot water operation in spite of the previous studies. We discovered that there is a close relationship between the collecting time of the seeds and the ration of seed infections, as well as germination percentage. Thus, the 2009 season was the most favourable in case of contamination (control: 17.3% and 80 °C treatment: 0%) as well as germination percent. It could be concluded that the best season for our findings was 2009 due to autumn harvest of Sida seeds. In our opinion, the autumn harvesting should be the best time to overcome the problem of the low germination and high infection percentage. We also discovered that apparently there is a close relationship between the seed fresh weight or water uptake capability and the percentage of infection. Following these recognitions, we modified our technique in such a way that we fractionated the seeds based on their fresh weight / or relative density before we carried out the treatment. When we filtered the floating seeds on the surface of water, the hot water treatment was performed considerably better on the sunk seeds after separation. Therefore by this special priming process, we were able to reach 80% germination capacity of Virgina mallow seeds under laboratory conditions (26 °C without illumination).
