Designing buildings that will exist and be inhabited for at least 50 – 100 years in the face of climate change is an exciting and non-trivial challenge. Currently, when designing the “Energy Efficiency” part, it is usual to use climatic data (solar and temperature), obtained from measurements in a limited number of meteorological stations on the territory of Bulgaria in the past 30-year climatic periods. This makes the newly designed buildings suitable for the past and not the future with the expected significant change in temperatures, air humidity, and other climatic parameters. Considering different possible trajectories of human behavior that lead to different climate consequences, the Intergovernmental Panel on Climate Change IPCC defined four climate scenarios under which corresponding global and regional climate models were created. They can be used to investigate the behavior of newly designed buildings in the warmer climate of the late 21st century. This methodology was applied to the study of a newly designed building in Bulgaria. The heating energy in the period 2061 – 2080 with climate scenario RCP 4,5 (90 %) will decrease by about 32 %. The cooling energy demand will increase by about 150 % and the dry cooling load – by about 170 % due to the substantial increase in summer outdoor temperatures. Adding active blinds to the design reduces the increase in dry cooling load to 93 %. [ABSTRACT FROM AUTHOR]

Unlabelled: Viral infections during pregnancy, along with some form of accompanying pregnancy diseases such as diabetes, cardiovascular, gastrointestinal, kidney and others, are a major cause of arising complications and mortality of mother and fetus., Aim: To improved the laboratory diagnostic approach in the study of women with pathological pregnancy, including improve treatment and prognostic character of the outcome of pregnancy, with the inclusion of two infectious agent parvovirus B19 and Chlamydia trachomatis. To determine types of anemia in pregnant women with parvovirus B19 and Chlamydia trachomatis infection and to select the correct therapeutic approach., Materials and Methods: A total 36 serum samples from pregnant women with anemia (n = 22), nonimmune hydrops fetalis (n = 8) and fetal ascites (n = 6) were tested. The study included three newborns (n = 3), tested on the occasion of a possible maternal-fetal infections. The serological (indirect ELISA tests) and molecular (B19V-PCR test) methods were used. In anemic pregnant women were evaluated iron homeostasis parameters with CLIA, AAS and NEPH methods., Results: In 6/36 (16.66%) patients B19V-IgM positive result was detected. Among the study patients with anemia, non-immune hydrops fetalis and fetal ascites incidence of proven B19V-IgM antibodies was 18.18% (4/22), 12.5% (1/8) and 16.66% (1/6), respectively. Protective B19-IgG antibodies in 25/39 (64.10%) samples were found. A positive PCR signal was showed in all patients with positive B19V-IgM, and 1 patient with anemia and positive B19V-IgG result. The three newborns were positive for B19V-IgG antibodies (maternal) and negative for acute viral infection. Present Chlamydia trachomatis infection in 6/36 (16.66%) and past infection in 5/36 (13.89%) patients was demonstrated. The anemia was evaluated as iron-deficiency according to low hepcidin levels 2.54 ± 0.4 μg/I compared to pregnant control group which included women without anemia 25.9 ± 2.8 μg/I., Conclusion: In view of the varied transmission B19V and the wide range of complications arising as a result of chlamydia, screening for these viral agents of pregnant women and women of childbearing age is an important approach for monitoring of pregnancy.

This study includes 1227 patients with congenital, inflammatory and vascular diseases of male genital system and proved the frequency of azoospermia.
