يتم تخزين الطاقة الحرارية في هيكل البناء بشكل كامن باستخدام مواد ذات درجة حرارة تحول طوري منخفضة تسمى المواد متغيرة الطور. تم في هذا البحث إجراء دراسة رياضية تحليلية لألواح المواد متغيرة الطور بالاعتماد على محاكاة السلوك الحراري لها حيت تم تحديد المعادلات الناظمة لعملية انتقال الحرارة ضمن الألواح عند تغير حالتها الطورية و تم تشكيل الموديل الرياضي اللازم، كما تم إنشاء النموذج اللابعدي الخاص للألواح عند استخدامها كطبقة فعالة في هيكل البناء.
Thermal energy can be stored as a latent heat in building structures by materials with low phase change temperature called phase change materials (PCM). In this paper, an analytical and mathematical study of the PCM wallboards was done by simulate its thermal behavior, depending on governing heat transfer equations which describe the phase change process of the PCM wallboard.

In this paper, an analytical and mathematical study of the PCM
wallboards was done by simulate its thermal behavior, depending on
governing heat transfer equations which describe the phase change
process of the PCM wallboard . A mathematical model
was done
and used to simulate the thermal behavior of several different
structures of the wall (single PCM wallboard, PCM wallboard +
thermal insulation layer, PCM wallboard + a concrete block).
Latent heat storage is an economical way to achieve energy
efficiency and improve thermal comfort in buildings.
In this research, the effects of using PCM Wallboards in a
residential apartment envelop located in Homs was studied by PCM
Express so
ftware.
PCM wallboard with 23°C melting temperature was used and
installed on the inner face of the walls and ceiling of the apartment.
This investigation shows that the importance of using PCMs in
buildings envelope, compared with conventional thermal insulation
materials, due to the effectiveness of PCMs materials and storing
and releasing of thermal energy, which contributed to reducing of
thermal loads and improved the internal thermal comfort.
In this research, the danger and the horizontal force effects on the
engineering structures will be explained, and we will focus on the
horizontal winds force effects on the bridges, the high buildings and
special engineering structures. The resul
ted loads will be analysed and
evaluated in both static and dynamic methods. In the end of the
research, two practical examples will be shown for the two methods.
This research was done by using a mathematical modeling for a heat storage tank by
the preparation a mathematical function using MATLAB software for charging and discharging
phase of the storage tank . it was applied partial storage strategy on a d
efault
building located in the city of Palmyra in the Syrian desert. peak cooling load (420 kW)
and storing (1420 kw-h) within a storage tank size of "30m3" So that the store of ice at
night and melting using outer fusion technology (External Melt) in thermal and electrical
peak hours in the next day .
The results showed the feasibility of a thermal modeling of the tank to cover the
air-conditioning load cooling load required ,the results also showed the shift of part of the
electrical daily load of the chiller about (576 Kw-h) with a clear reduction of mechanical
and electrical equipment with the provision of using electrical energy to a summer season
about (1376 kW-h/Season) and improving the daily electrical factor (DLF) achieves stability
of the electric system.
This paper presents the results can be generalized to large projects in the tropics
help in thermal and power consumption peak shift.
In this paper, we will focus on the types of roof’s brick used
in construction and theoretically compare thermally between
different kinds in the local market, and finally we will propose a
new form of roof’s brick give the optimal insulation without
increasing the weight.
