The Impact

Purpose. The purpose of the work is analysis of violations of natural lighting conditions (insolation) in residential buildings, because in the modern conditions of construction the role of direct sunlight as a natural health factor has increased significantly, multi-storied buildings in cities are becoming increasingly detached from natural conditions. Method. The methodology is based on a comprehensive and objective analysis of the SSTC-R B normative document R.2.2-27: 2010 “Guidance on the Calculation of Civilian Object Insolation”. Results. It has been investigated during the process of analysis that the regulation and calculation of insolation is the most acute economic and social-legal problem. With the transition of land usage and construction to the market basis, building insulation rates have become a major factor in holding back investors, landlords and tenants from seeking to redevelop urban development in order to maximize profits. Scientific novelty. Imperfect normalization was found under the current conditions in the course of the research, which can lead to serious errors in the design and evaluation of the insulation regime of the apartment and the house as a whole. The maximum shade mask of a new home shall correspond to the maximum possible height of the projected house or to the combination of the maximum heights of each individual section at which the insolation regime in the premises of the existing house or in the surrounding area shall meet the regulatory requirements or shall not deteriorate during the normalized period of insolation. If the insolation is interrupted more than once, then for the estimated duration of the insolation, the sum of the duration of the two largest insolation periods should be taken. Practical meaning. The results of the study may be useful in further studies of violation of natural light conditions, as well as the impact of residential development on insolation processes.

The urban fabric of the desert cities is based on the principle of reducing the impact of urban canyons on direct solar radiation. Here comes this research, which is based on a comparative study of the periods of direct solarisation and values of the solar energy of urban canyons via two urban fabrics that have different building densities, where the ratio between L/W is different. In order to obtain the real values of the solar energy (thermal, lighting), the test field was examined every two hours, each three consecutive days. The measurement stations are positioned by the three types of the relationship between L/W, (L≥2w, L=w, L≤0.5w). According to the results, we noticed and recorded the difference in the periods of direct solarization between the types of urban engineering canyons, reaching 6 hours a day, the difference in thermal values of air, reaching 4 °C, and the difference in periods of direct natural lighting, reaching 6 hours. It should be noted that the role of the relationship between L/W is to protect the urban canyons by reducing the impact of direct solar radiation on urban canyons, providing longer hours of shading, and reducing solar energy levels (thermal, lighting) at the urban canyons. This research is classified under the research axis (the studies of external spaces in the urban environment according to the bioclimatic approach and geographic approach). But this research aims to focus on the tracking and studying the distribution of the solar radiation - thermal radiation and lighting radiation - in different types of street canyons by comparing the study of the direct solarization periods of each type and the quantity of solar energy collected during the solarization periods.

In recent decades floral devices in a natural style has been becoming more common in gardening. In this connection there was a need for the introduction and study of the natural flora of plants in order to attract them to simulate the decorative and resistant plants. The article presents the results of studies of the effect of different light conditions on the habitat features and decorative biomorphological Hylotelephium triphyllum (Haw.) Holub (Crassulaceae DC.) when introduced in SE Donetsk Botanical Garden. This species is found naturally in the flora of Donbass, a decorative, but, according to the results of our analysis, is rarely used in green construction. Bioecological certification of this type has been done. It has been determined that the impact of site lighting conditions on the growth and development of H. triphyllum expressed in significantly smaller numbers of vegetative and generative shoots in the shaded areas. However, since the diameter of the plants does not change, more thickened planting in these areas is not recommended. The author found the dependence of the variation of the biometric data on the lighting conditions. In the study of seasonal dynamics of H. triphyllum the author revealed that the development of above-ground organs of his passes with a positive amount of average daily air temperatures. The growing season lasts an average of 225 days. Start of spring regrowth is observed in the second half of March - early April, flowering - in August - September, fruits - in September - October. Vegetation stops when temperature goes below zero. Illumination of this type of habitat affect the time of vegetation beginning, budding, flowering, fruit set and fruit-bearing. On the shaded areas due to the later start of budding and flowering the most decorative period of H. triphyllum is shorter by an average of 10 days. This type is recommended for creation of group planting, stony hills, dry streams, rock gardens, rockeries, mixborders, curbs, ornamental compositions in the coastal zone of ornamental ponds and fountains in the steppe zone in areas with different light conditions, taking into account the above factors.

Abstract LED lighting has emerged as alternative to the current HPS standard in greenhouse production. However little is known about the impact on fruit quality under the different light spectra. We grew a biparental tomato RIL population between September 2019 and January 2020 under two commercial greenhouse supplemental lighting conditions, i.e. HPS, and 95% red/ 5% blue- LED, of about 220 µmol m− 2 s− 1 at maximum canopy height for 16h per day. Differences in Brix and blossom-end rot (BER) between the two light conditions were observed and we studied the genetic influences on those traits, separating genetics located on chromosomes from genetics located in plastids. The Brix value was on average 11% lower under LED than under HPS supplemental lighting. A LED-light specific QTL for Brix was identified on chromosome 6. This QTL can be of interest for breeding for tomato varieties cultivated under LED supplemental lighting. A Brix-QTL on chromosome 2 was found for both light conditions. In our study fewer plants developed BER under LED supplemental lighting than under HPS. We identified a novel genetic locus on chromosome 11 for the incidence of BER that lead to a difference in about 20% of fruits with BER. This genetic component was independent of the light.

The Impact

Energy savings gained through natural lighting could be offset by the loss of energy through windows; therefore, the target of this study is to examine the effects of enhancing the efficiency of lighting systems on the optimum window-to-wall ratio (WWR) of Jordanian residential structures. This research proposes the hypothesis that the WWR of residential structures that contain artificial lighting systems with increased efficiency will be lower than buildings in which solar lighting is provided. The energy simulation tool, DesignBuilder, was used to simulate an intricate model showing a standard Jordanian residential building with a size of 130 m2. The study offers useful guidance regarding the optimum WWR for key decisionmakers when designing energy-efficient residential structures in the context of Jordan. By considering the balance between gains and losses in solar heat and light gain to exploit energy from solar sources with no reverse effects, while making comparisons between different WWR situations, the findings indicate that the typical WWR for residential structures in Jordan that have efficient Light Emitting Diode (LED) systems of lighting installed could be between 25% and 30%, which is lower than the highest WWR stipulated by the ASHRAE standards.

This study is mainly concerned to assess the role of Risk Communication in Earthquake Vulnerability and its impacts on Building Resilience in District Bagh Azad Jammu and Kashmir. Disaster resilience is gaining attention from all over the world. More specifically, seismic resilience in buildings is of prime concern among governmental bodies of developed as well as developing countries. This is partially due to the fact that the collapsing of vulnerable structures contribute to a great proportion of the number of fatalities in the wake of increasing Seismicity. Secondly, the recurrence of earthquakes on a global scale is increasing with increase in its magnitude. This study was focused to assess the impact and role of risk communication in earthquake vulnerability in district Bagh, Azad Jammu and Kashmir in enhancing resilience of residential buildings and also its moderating role between Earthquake Vulnerability and resilience of residential buildings in study area. In fact there is great gape; people in the vulnerable areas do not get required information about various hazards. For this study District Bagh of Azad Jammu and Kashmir was selected due to the facts, it suffered a lot during 2005 Earthquake and still it is prone to more damages due to lack of implementation of building codes and requisite information on the vulnerability. An exploratory type of study has been conducted. For pilot study 50 respondents were approached for collection of data with the help of questionnaires in different areas of District Bagh. Findings of the pilot study along with recommendations for policy makers, managers and target readers have been given in detail. Contribution to the body of knowledge and future call is also jotted down. If people are educated well about various hazards they can reduce the vulnerability to a great extent. Nevertheless, through better integration of risk communication means and enhancing level of awareness would prove instrumental in overcoming the lapses Keywords: Risk communication, Earthquake vulnerability and Resilience.

AbstractCurrently, there are many initiatives to thermally insulate buildings on the assumption that the more insulated the building is, the more efficient in terms of energy conservation it will perform. Many assessment systems assume a linear relationship between building insulation and energy conservation. The drawback of such hypotheses is that they ignore the effect of occupants’ behaviour in their conclusions. In this study, the authors will examine the effect of people’s behaviour, particularly windows’ opening, as a behavioural pattern of occupants. It aims to study the impact of occupant’s behaviour on energy consumption of residential buildings and to identify the key factors that influence occupants’ behaviour; thus, providing ideas for improving energy efficiency by suggesting enhanced policies, approaches and techniques. The findings suggest that occupants’ behaviour could have a greater influence on the energy efficiency of buildings in some cases when compared with their thermal insulation due to opening of windows in cold weather which causes air infiltration.

ABSTRACT Beginning at the summer solstice adult female mink were maintained in long- or short-day photoperiods and treated with bromocriptine or prolactin. In control females kept under natural lighting conditions the moult coincided with the seasonal decrease in prolactin and resulted in the growth of a dense winter coat which was completed by the end of November. Long days, which slowed the decrease in plasma prolactin relative to animals in the natural photoperiod, induced a more or less complete moult followed by growth of a thin summer coat. On the contrary we observed an accelerated decrease in plasma prolactin concentrations followed by an early and brief moult in females kept under long days but treated with bromocriptine and in females under short days. The growth of a dense winter coat was completed by the end of September in all the females of the short-day group and in six of eleven females treated with bromocriptine. In the other five females, moult was followed by the growth of a summer coat. These results may suggest that the decline of prolactin after the summer solstice is responsible for the onset of the autumn moult, but the early, abbreviated moult and the growth of a winter coat observed in females kept under short days and treated with prolactin do not seem to support this hypothesis. However, the huge non-physiological levels of prolactin measured in the plasma of these females and the appearance of abnormal white under-hairs might suggest that the hormonal balance in this group was completely disturbed by the treatment. The physiological role of prolactin in the seasonal moulting cycle in mink is discussed. J. Endocr. (1984) 103,9–15
