Abstract

Perubahan iklim yang terjadi saat ini ditandai oleh peningkatan suhu permukaan bumi, salah satu dampak yang dirasakan cukup signifikan adalah kondisi kenyamanan termal dalam bangunan. Sehingga hal tersebut akan mendorong para penghuni untuk menggunakan AC untuk mengondisikan tingkat kenyamanan termal yang di butuhkan. Dari hasil prakiraan kebutuhan listrik, dari tahun 2017 sampai 2036 kebutuhan listrik akan meningkat 6,4% setiap tahunnya yang didominasi oleh sektor rumah tangga sebesar 38,49%. Sehingga upaya mengondisikan kenyamanan termal ruangan untuk mengurangi jangka waktu pengoperasian AC dapat dilakukan. Hal tersebut dapat diwujudkan melalui building energy retrofitting, khususnya pada rumah tangga middle low income. Retrofitting juga tidak akan memakan biaya yang tinggi sehingga cocok untuk rumah tangga middle-low income. Pada penelitian ini, retrofitting dilakukan dengan menerapkan ventilasi, diharapkan ventilasi menyediakan udara menuju ruangan tertentu secara alami melalui perpindahan dan pertukaran udara. Penelitian ini menerapkan 12 variasi pada ventilasi yaitu variasi dengan cross ventilation dan non cross ventilation kemudian divariasikan ukuran ventilasi dan jumlah ventilasi. Penelitian ini dilakukan berbasis simulasi dengan Computational Fluid Dynamics. Setelah dilakukan simulasi, diperoleh penurunan temperatur dalam ruangan yang paling besar adalah ketika malam hari menerapkan cross ventilation dengan ventilasi ukuran 30 cm x 70 cm dengan jumlah 4 ventilasi, yaitu dengan penurunan temperatur rata-rata dalam ruangan sebesar 1,614℃. Setelah itu, dilakukan cost-benefit analysis untuk membandingkan biaya dan manfaat dari suatu proyek, diperoleh rasio cost-benefit 1,26 dimana keuntungan lebih besar dari biaya pengeluaran, diperoleh nilai payback period sebesar 0,402 atau modal dapat kembali selama 5 bulan dan sehingga diperoleh penghematan biaya konsumsi listrik sampai tahun ke 5 sebesar Rp 24.340.306.

The current climate change is marked by an increase in the earth's surface temperature, one of the impacts that is felt quite significantly is the condition of thermal comfort in buildings. So that this will encourage occupants to use air conditioning to condition the required level of thermal comfort. From the results of the forecast for electricity demand, from 2017 to 2036 electricity demand will increase by 6.4% annually, which is dominated by the household sector at 38.49%. So that efforts to condition the thermal comfort of the room to reduce the operating time of the air conditioner can be carried out. This can be realized through building energy retrofitting, especially for middle-low income households. Retrofitting also doesn't cost a lot, making it suitable for middle-low income households. In this study, retrofitting was carried out by applying ventilation, it is hoped that ventilation will provide air to certain rooms naturally through air movement and exchange. This study applies 12 variations in ventilation, namely variations with cross ventilation and non-cross ventilation then varies the size of the ventilation and the number of ventilations. This research was conducted on a simulation basis with Computational Fluid Dynamics. After the simulation, it was obtained that the greatest decrease in indoor temperature was when applying cross ventilation with a ventilation size of 30 cm x 70 cm with a total of 4 ventilations at night, with an average decrease in indoor temperature of 1.614℃. After that, a cost-benefit analysis is carried out to compare the costs and benefits of a project, a cost-benefit ratio of 1.26 is obtained where the profit is greater than the outlay, a payback period value of 0.402 is obtained or capital can be returned for 5 months and thus savings are obtained. the cost of electricity consumption until the 5th year is IDR 24,340,306.
