IMPROVING INDOOR THERMAL COMFORT IN RESIDENTIAL BUILDINGS IN HOT-ARID CLIMATES THROUGH THE COMBINATION OF NATURAL VENTILATION AND INSULATION RETROFITTING TECHNIQUES - Case study: Existing social housing stocks in Greater Cairo
No full textAchieving thermal comfort in buildings has currently become an urgent need, because
of excessive demand in energy consumption across the length and breadth of the
world. Accordingly, academics, policy-makers, regulators and governments are striving
to find solutions that can be applied to achieve thermal comfort in buildings without
excessive consumption of energy. Corollary to this, thermal comfort and energy
efficiency in buildings are two faces on the same coin.
Egypt is characterised by haphazard utilisation of prototypical design in public
housing projects. The haphazard utilisation of prototypical strategy is in stark contrast
with the conventional strategy, which takes into account the various climatic design
issues in carrying out social housing projects. Previous studies indicated that the
thermal behaviour of same building stock varies across Egypt due to different climatic
regions. This evidence overtly illuminates that in order to ensure thermal comfort in
residential buildings in Egypt, a combined strategy that takes into consideration the
prevailing climatic condition is imperative. It is therefore, against this backdrop that
this study examined how the combination of natural ventilation behavioural strategies
and insulation retrofitting technique influences indoor thermal comfort without using
any mechanical cooling or heating systems.
In order to accomplish the research aim, the problem of thermal comfort in the
prototype design social housing building stocks within the hot arid climate of Egypt
was identified. Further, the Integrated Environmental Solution – Virtual Environment
(IESVE) was adopted to predict the building thermal behaviour whilst applying
natural ventilation behavioural strategies on the one hand and its combination with
insulation retrofitting technique on the other hand. Predictions were comparatively
analyzed to identify the optimum strategy during each month of the year. Cross
analyses were carried out to ascertain either this strategy highlights the differences
among building orientations or otherwise. In addition, a comparison between typical
and upper floor was conducted to highlight their differences.
By applying natural ventilation behavioural strategies, scenarios of natural ventilation
were categorized into three; the base case scenario, the actual behavioral scenarios and
the hypothetical suggested scenarios. The results illuminated that, In terms of the
summer season, the hypothetical suggested scenario of cross night purge ventilation
revealed a considerable improvement in indoor thermal comfort. Moreover, whilst
natural ventilation scenarios had a modest improvement in thermal comfort in springautumn
period, it had a negative effect in winter season.
In regards to the combination strategy, simulation results revealed that whilst this
strategy played a major role in increasing indoor thermal comfort and reducing
cooling demand in summer period, it had very slight impact on enhancing indoor
comfort and reducing heating demand (in winter) and heating or cooling demand (in
spring-autumn periods). However, by comparing the combined strategy with natural
ventilation only, it was deduced that the insulation technique had relatively small
impact on thermal comfort enhancement in all periods of the year.
Improving indoor thermal comfort in residential buildings in hot‐arid climates through the combination of natural ventilation and insulation retrofitting techniques
II
The study further assessed the effect of orientation on indoor thermal comfort via the
utilisation of natural ventilation only as well as the combined strategy in winter,
summer and spring-autumn periods. The observable fact illuminated that the
orientation has no significant effect on indoor thermal comfort in winter, summer and
spring-autumn seasons. Finally, the comparison between typical and upper floor
confirmed that the difference between them is negligible in terms of thermal comfort
Effect of Orientation on Indoor Thermal Neutrality in Winter Season in Hot Arid Climates Case Study: Residential Building in Greater Cairo
No full textThis work analyzes the effect of prototypical apartments’ orientation on indoor thermal comfort as a case study. The appartments are in a residential building block in October 6th city in Greater Cairo, Egypt. Field measurements of indoor air temperature (Ta,in) and relative humidity (RHin) were monitored in three hour intervals in the winter season of 2013 during one week in January. Outdoor measurements for the ambient temperature and relative humidity were obtained from the Meteorological Authority in the same period. The indoor measured data of air temperature and relative humidity were used to specify the comfort zone of each apartment in different orientations in the reference case by using ASHRAE psychrometric chart. This is considered the first part of the study and the second part will be conducted in the summer season to discuss the indoor thermal comfort for the reference case. a visual survey was conducted in order to analyze the construction materials and façade features of the buildings. Personal observations, , field measurements and ASHRAE psycrometric chart analyses show that there is significant thermal discomfort inside the apartments, while changing the orientation had an insignificant effect on improving thermal conditions during the survey period
Effect of Orientation on Indoor Thermal Neutrality in Summer Season in Hot Arid Climates
No full textThis work analyzes the effect of prototypical apartments’ orientation on indoor thermal comfort. The apartments are located in a residential building block in October 6th city in the hot-arid climate of Greater Cairo, Egypt. Indoor air temperature (Ta,in) and relative humidity (RHin) were monitored in three hour intervals in the summer season of 2013 during the last two days of June. Outdoor measurements for the ambient temperature and relative humidity for the month of June were obtained from the Meteorological Authority. the comfort zone for the reference case was specified by using ASHRAE psychrometric chart. This is considered the second part of a study that was conducted in the winter season of 2013 to discuss the effect of orientation on indoor thermal comfort for the same reference case in January. A visual survey was conducted in order to analyze the construction materials and façade features of the buildings. Personal observations, field measurements and ASHRAE psycrometric chart analyses show that there is significant thermal discomfort inside the apartments. Furthermore, comparing the three orientations; Northern, Eastern and Western showed that whilst the Northern has a little difference, there is no significant effect on thermal comfort indoors between Eastern and Western orientations

Syriac-Arabic Glosses of Isho bar Ali. Volume 2
No full textThese two volumes constitute the second part (nun-taw) of the Syriac-Arabic dictionary of the 10th cent. physician Isho bar Ali (the first half of the dictionary had been published in 1874 by G. Hoffmann). Each Syriac word is defined in Arabic, often with more than one Arabic equivalent; in addition, the author deals not just with individual Syriac words, but in some cases with phrases. Gottheil used 21 manuscripts (from Oxford, London, Paris, Berlin, Leiden, and Rome) for this edition, and he has supplied a thorough critical apparatus; the manuscripts are described in the introduction. While some manuscripts give the Arabic glosses in Syriac characters (i.e. Garshuni), Gottheil has presented them here in Arabic script. These two volumes will be of great interest to Syriac lexicographers and those who study interactions between Syriac and Arabic.Contains an English introduction by Richard J.H. Gotthei

The Impact of Tablet-Based Video Materials on Second-Grade Students’ Phonics Skills at Ali-Sabieh 1 Elementary School
No full textAs tablet integration in education becomes increasingly prevalent in Djiboutian classroom settings, understanding their effectiveness is crucial. This study examined the impact of tablet-based video materials on the phonics skills of second-grade students at Ali-Sabieh 1 elementary school in Djibouti. Using a quasi-experimental design, 38 students were divided into experimental and control groups. Pre-test and post-test assessments were conducted to evaluate pupils’ phonics skills before and after the experiment. Independent samples t-test results indicated no significant difference in post-test scores between the experimental and control groups. These findings suggest that while digital learning videos can support phonics skills development, their impact may not be significantly greater than traditional learning methods. This study contributes to the limited research on educational technology in Djibouti and provides insight for future implementations of digital tools in literacy education.departmental bulletin pape
