“…The AC electricity usage in most of the targeted dwellings is positively correlated with outdoor temperature, for which the correlation coefficient ranged from -0.1 to 0.5. Yoshino et al, [25] also revealed a strong correlation between the cooling energy consumption and the outdoor temperature.…”

Electricity consumption by air-conditioners in residential buildings significantly affects the electrical grid. The stability of the grid can be improved by a precise prediction of air-conditioning (AC) variations. Therefore, more information about the electricity usage patterns specifically on AC load is important. This paper aims to determine the consumption patterns of AC and total load through a field measurement of 20 dwellings located in Kuala Lumpur and Selangor. Next, correlation and clustering are employed to identify the relationship between outdoor temperature and AC electricity consumption. The results revealed 75% of the occupants use the AC almost every day for about five to six hours per day at the rates of 0.93 kWh/day during day time and 3.43 kWh/day during night time. The correlation coefficient between the total daily AC consumption and the mean daily outdoor temperature ranged from -0.1 to 0.48. The variation of electricity consumption with time shows that AC electricity consumption increases with the increase of usage time. Lastly, the clustering process of AC usage pattern based on outdoor temperature displayed the uncommon behaviour from dwellings whereby high AC electricity consumption was recorded at low outdoor temperature.

T. 2012 Haas, et al (1998) dalam Ouyang, J., et al (2009) menjelaskan bahwa perilaku pengguna merupakan faktor yang paling berpengaruh terhadap konsumsi energi rumah tangga. Yoshino, H., et al (2006) mengklasifikasikan 6 kategori konsumsi energi, yaitu sistem penghawaan, penyediaan air panas, dapur, audio visual/ informasi, perawatan kesehatan, pencahayaan, dan sebagainya.…”

Arah pengembangan hunian vertikal berupa rumah susun umum untuk kalangan masyarakat berpenghasilan rendah menjadi prioritas pembangunan Pemerintah Kota Malang pada tahun mendatang. Kelayakan desain rumah susun perlu dikaji lebih lanjut agar terwujud desain rumah susun yang hemat energi. Penelitian ini bertujuan untuk mengetahui karakteristik konsumsi energi bangunan pada rumah susun umum dilihat dari karakteristik pengguna terhadap kondisi termal dan konsumsi energi bangunan pada rumah susun umum. Metode yang digunakan dalam penelitian ini, yaitu metode kuantitatif dengan teknik pengumpulan data berupa data primer melalui observasi lapangan, survei (wawancara dan kuesioner), dan data sekunder. Sedangkan teknik analisis data dilakukan dengan menggunakan analisis perbandingan dan korelasi. Hasil akhir penelitian didapatkan bahwa semakin berpendidikan dan mapan kondisi finansial penghuni, memiliki kecenderungan makin meningkat pula konsumsi energi bangunan. Hal ini tentu sangat dipengaruhi oleh desain bangunan, karakteristik, dan pola perilaku penghuni terhadap kesadaran managemen kontrol energi bangunan. Penerapan strategi kontrol energi bangunan yang baik diharapkan dapat menambah durabilitas bangunan dengan perawatan minimal, tercapai nyaman termal dalam ruang, tingkat konsumsi energi lebih sedikit, dan tercapai kehidupan yang layak dan sehat bagi penghuni rumah susun.

“…A study on energy consumption for residential buildings in Japan carried out by the Architectural Institute of Japan (AIJ, 2006), which included an internet questionnaire survey of 4,000 households and detailed on-site investigations of 80 houses throughout Japan. And the two years detailed monitoring of energy consumption and indoor temperature of 13 housing units in the northern region of Honshu Island, Japan, by Yoshino et al (2006). Although these types of questionnaire surveys and long-term on-site measurements provide accurate data, they are very costly and time consuming.…”

This study investigated the interrelationships among household energy consumption and indirect lifestyle aspects (including life schedule and family pattern), with particular emphasis placed on energy consumption pattern changes according to climatic characteristics. Instead of the conventional questionnaire survey and on-site measurement methods, this study focused on estimating the lifestyle related household energy consumption using life schedule data, which, in contrast, is low cost and time efficient. This study found that household energy consumption increases according to family size, however the per person energy consumption rate is less in larger size families. Retirees and housewives generally consume more household energy than working and student groups. Among working groups, household energy consumption increases according to age. Employee groups tend to consume less household energy than businessmen/women groups, while female working groups consume more household energy than male working groups. Also, people engaged in the agriculture/forestry sector and the self-employed consume more household energy, while labor and management/technical sectors consume the least. This study also revealed that households in colder regions generally consume more household energy due to higher energy needs for heating and lighting.
