A B S T R A C TAlthough the air-conditioning intermittent operation is widely used in buildings, more attention is focused on the air-conditioning continuous operation in the whole building to simplify energy conservation design, and thereby, the operation method inconsistence of air-conditioning must lead to the large difference between actual value and design value of energy consumption. According to this situation, in order to explore the wall energy conservation difference under the continuous and intermittent operation of air-conditioning, a experiment is built to analyze the effect of the thermal insulation layer location on wall dynamic thermal response rate. Experimental result shows that under the air-conditioning intermittent operation, wall cold storage is the main source of air-conditioning load formed by walls and the wall internal layer has the significant effect on the wall dynamic thermal response performance. And the closer to wall inner surface for the thermal insulation layer, the lower the inner surface temperature and the higher the wall thermal response rate. Meanwhile, the internal thermal insulation wall has the smallest heat flow value, which is less 35-86% than external thermal insulation wall and the sandwich thermal insulation wall, although they have the same heat transfer coefficients.

“…The finding does not correlate with ISO 7730 and ASHRAE 55-2004 standards. Budaiwi & Abdou (2013) investigate the heating, ventilation, air conditioning (HVAC) system operational strategies for reduced energy consumption in mosques with intermittent occupancy. The study was conducted at three different sizes of air-conditioned mosques (different floor area) in eastern province of Saudi Arabia.…”

In a mosque environment, occupants are temporarily in the situation of various dress and congregate activities which desire comfortable environment. Inappropriate thermal comfort condition in a mosque leads the distraction in fulfilling the religious practice and also causing emotional influence. The proper setting of thermal comfort parameters is important to provide a suitable environment for the mosque occupants. Proper investigations of thermal comfort may help to optimize the usage of the cooling systems such as air conditioning system. The objective of this paper is to investigate the thermal comfort performance of large-scale retrofitted air-conditioned mosques with intermittent operation in Penang, Malaysia. According to the survey, the mosques in this region can be categorized into five groups (G1 -G5) according to floor area (131.55 m 2 to 2,920 m 2 ). A case study is conducted on a large scale mosque with a floor area of 2,920 m 2 that is equipped with a centralized air-conditioning system. Result shows that the system produces an indoor thermal environment that within the range recommended by ASHRAE Standard 55. Most of the predicted thermal sensation under predicted mean vote (PMV) indices is achieved and within the comfort zone range (-0.5, +0.5). Some thermal strategies need to be applied especially on air conditioning system, operation configuration, handling procedure, zoning section as well as technical knowledge among mosque officials. Hence, the energy consumption of the mosque can be reduced while maintaining thermal comfort level of occupants. kawasan ini boleh dikategorikan kepada lima kumpulan (G1-G5) berdasarkan keluasan lantai (131.55 m 2 kepada 2,920 m 2 ). Satu kajian kes telah dijalankan ke atas masjid berskala besar, 2,920 m 2 yang dilengkapi sistem penghawa dingin jenis berpusat. Hasil menunjukkan bahawa sistem menghasilkan persekitaran terma dalaman di dalam julat yang dicadangkan oleh piawaian ASHRAE 55. Kebanyakan ramalan terma sensasi di bawah indeks undi min ramalan (PMV) adalah tercapai dan berada dalam julat zon selesa (-0.5, +0.5). Strategi penambahbaikkan terma persekitaran perlu dilakukan terutamanya melibatkan pengendalian sistem penghawa dingin, konfigurasi pengoperasian, prosedur pengendalian, seksyen pengezonan serta pengetahuan teknikal di kalangan pegawai-pegawai masjid. Oleh yang demikian, penggunaan tenaga masjid dapat dikurangkan serta dapat mengekalkan tahap keselesaan terma di kalangan jemaah.
