Indoor Air Conditions And Energy Consumption In Air-Conditioned Office Rooms In Hot-Humid Climate : Towards Better Energy Management.
Masters thesis, Universiti Sains Malaysia.
Abstract
Objektif kajian ini adalah untuk menyelidik keadaan udara dalaman dan penggunaan tenaga dalam bilik pejabat berhawa dingin yang terpilih di dalam zon iklim panas-lembap. Kajian ini juga mengkaji tren tenaga dan persepsi penghuni terhadap keadaan udara dalaman dan menganalisis hubungkait di antara penggunaan tenaga dan keadaan udara dalaman di dalam bilik pejabat berhawa dingin. Bagi mencapai objektif, penyelidikan ini telah dijalankan di dalam 30 bilik pejabat berhawa dingin yang terpilih merangkumi pengukuran keadaan cuaca luaran, keadaan cuaca dalaman, penggunaan tenaga dan kaji selidik. Keputusan telah menunjukkan bahawa keadaan cuaca dalaman berubah secara berbeza dan responden amat berpuas-hati dengan keadaan tersebut walaupun suhu dalaman dan halaju udara dalaman adalah gagal mematuhi garid Malaysia DOSH. Keputusan juga dapat menujukkan bahawa halaju udara dalaman dikaitkan dengan kelembapan dan suhu luaran mempunyai kesan yang besar pada suhu dalaman di dalam bangunan. Hasil kajian ini juga mendedahkan kecukupan pengetahuan dan kesedaraan tentang kecekapan tenaga menyebabkan kepuasan dari segi mengguna tenaga di antara responden.
The objectives of this research are to investigate the indoor air conditions and energy consumption in selected air-conditioned rooms in hot-humid climate zone. This research also explores the energy knowledge, attitude and practices (KAP) and occupants’ perception on indoor air conditions and analyses relationship between energy consumption and indoor air conditions. This research was conducted in 30 selected air-conditioned rooms in hot-humid climate that includes measurements of outdoor climatic conditions, indoor air conditions, energy consumption and questionnaire survey. The results showed the indoor air conditions varied greatly and the respondents were satisfied with it although the indoor temperature and air velocity were failed to comply with the Malaysia DOSH guideline. The findings showed that the indoor air velocity was correlated to indoor relative humidity and the outdoor temperature also has a great impact on indoor temperature in the buildings. The findings further revealed a satisfactory energy conservation practice by the occupants due to satisfactory levels of knowledge and awareness on energy efficiency.
