The Relationship

Research towards understanding the relationship between maintaining thermal comfort and energy efficiency in the public utility buildings was undertaken among 323 1st year students during class hours. Questionnaires surveys and measurements of indoor conditions were performed. The article identified students’ sensations and perceptions concerning indoor conditions. Temperature, relative humidity, air velocity and CO2 concentration measured to assess room conditions showed that the auditorium had almost comfortable conditions according to the literature guidelines. The indices used to assess students’ perceptions were: Thermal Sensation Vote (TSV), Thermal Preference Vote (TPV), Air Freshness Sensation Vote (AfSV), Air Movement Preference Vote (AmPV), and Relative Humidity Preference Vote (RHPV). The interpretation of these indicators showed that while the students’ requests for temperature changes and increased air movement are adequate for the air conditions in the room, the evaluation of stuffiness and requests for changes in humidity levels are surprising. Striving uncritically to meet the desired room parameters, according to the users votes, can lead to deterioration of the air and not only the increase in energy consumption but even waste it. Better understanding of users’ preferences and behaviour and further application of this knowledge indirectly aim at increasing energy efficiency in buildings.

The Relationship

The growth of the scale of cities intensifies urban heat island (UHI) by obstructing the wind and building more radiation at pedestrian level, thus leading to an energy consumption. Commercial pedestrianized-zones cannot only become symbols of cities but also an important factor increasing local economic income. This study conducts on-site measurement and numerical simulation to evaluate the cooling energy efficiency of different parameters (building, vegetation, pavement material) in Fo Shan city, which locates in hot-summer and warm-winter climate region of China. Also, calculations are done to evaluate the index physiological equivalent temperature (PET) for understanding thermal sensation at a pedestrian level (1.5 m). To evaluate different impacts of this zone renewal on the environment and choose the most energy-saving method, it is easy for us to utilize the linear regression for understanding the relationship between coverage ratio of trees (TCR) and thermal comfort in canyon space, which shows that ∆PET = 0.1703 × TCR + 0.2444 with a most important R2 value of 0.9836, for TCR increases from 12.5% to 22%. In open space, also increasing coverage ratio of trees (TCR) can effectively improve humans’ thermal comfort, which shows that ∆PET = 0.2644 × TCR + 0.3955 with a most important R2 value of 0.8892.

     The relationship between man and climate is of great importance in climate studies, as climate is the most natural climatic element in the sense of comfort or distress of man, and humans can live comfortably if the degree of heat between (17-31 m) and the human feeling of heat and cold and then rest or discomfort not only caused by the air temperature but depends on many elements including solar radiation, air movement, relative humidity, the level of human activity and the type of clothing worn, and the presumption has used Biophysiological temperature and Cooling guide in this study to demonstrate the impact of climate on human comfort in the city of Rutba and relying on the climatic data for thirty years.

Lighting is an important part of the building installations. Current lighting trends in the public and private sectors make lighting energy a significant part of the total electricity consumption of facilities. The provisions included in the standards, directives and regulations prescribe the implementation of the measures contributing to the reduction of electricity consumption, i.e. the improvement of energy efficiency of facilities. The article shows current trends and solutions concerning the reduction of electricity consumption in lighting installations, with the main focus on public utility facilities. The proposed systems are universal and can be implemented in various objects with different purpose and use.

AbstractThe article presents test research on thermal sensations, thermal preferences, as well as general thermal sensations in a single-family building. Graphs were drawn to determine the frequency of answers chosen by the respondents and the relationship between temperature and thermal sensations, as well as the influence of relative humidity on thermal sensations. A comparison was also made between the average thermal sensation vote and the PMV index, which determines the ‘predicted mean vote’ - estimated by the Fanger model. The aim of the study was to compare the actual feelings of the respondents with standard guidelines. As a result of this analysis it was found that the thermal sensations of the respondents do not comply with the adopted model included in the standard.

The focus of this study is to find the relationship between El Nino and dengue fever cases in the study area.Mosquito density was recorded with the help of light traps and through aspirators collection. Climate data were obtained from National Meteorology and Environment centre. (Year wise El Nino and La Nina data are according to NOAA & Golden Gate Weather Services). Statistical methods were used to establish the correlation coefficient between different factors. A high significant relationship was observed between Relative Humidity and Dengue fever cases, but Aedes abundance had no significant relationship with either Relative humidity and Temperature. Our conclusion is that the El Nino does not affect the dengue transmission and Aedes mosquito abundance in this region, which is supported by earlier works.

The Relationship

This paper maps the basic opposition groups that influenced the Egyptian political system in the last years of Hosni Mubarak’s rule. It approaches the nature of the relationship between the system and the opposition through use of the concept of “semi-opposition.” An examination and evaluation of the opposition groups shows the extent to which the regime—in order to appear that it was opening the public sphere to the opposition—had channels of communication with the Muslim Brotherhood. The paper also shows the system’s relations with other groups, such as “Kifaya” and “April 6”; it then explains the reasons behind the success of the Muslim Brotherhood at seizing power after the ousting of President Mubarak.

Systematic Explanation

This study is based on the legal responsibility of the assessment of public appraisal reports they make in land procurement activities for development in the public interest. Public assessment is obliged to always be accountable for their assessment. The type of research found in this thesis is a type of normative legal research with the right-hand of the statue approach and case approach. Normative legal research is a study that provides systematic explanation of rules governing a certain legal category, analyzing the relationship between regulations explaining areas of difficulty and possibly predicting future development. . After conducting research, researchers found that one of the causes that made the dispute was a lack of communication conducted between the Government and the landlord. In deliberation which should be the place where the parties find the meeting point between the parties on the magnitude of the damages that will be given, in the field is often used only for the delivery of the assessment of the compensation that has been done.

The Relationship

Today in Germany, religion and the churches forfeit their sovereignty of interpretation and ritual concerning death and dying. The funeral director is the first point of contact when death occurs. Therefore he or she is able to influence the relationship between the living and the dead. In the course of this development, the dead body, often referred to as dirty and dangerous, is being sanitized by funeral directors. Funeral directors credit the dead body with a certain quality; they claim that facing the dead may lead to religious or spiritual experiences, and therefore they encourage the public viewing of the dead – a practice which was, and still is not very common in Germany. The new connotation of the dead body is an example for the dislimitation of religion in modern society. The religious framing of death-related practises no longer exclusively belongs to traditional religious institutions and actors, but can take place in commercial business companies as well.
