“…4 ) was used to study the formation of urban heat islands (UHI) in the region. UHI formation is significantly related to the multiple neighbourhood morphological and metrological factors like sky view, height of the buildings, aspect ratio of the canyon, canyon radiative geometry, thermal properties of the urban materials, anthropogenic heat release, form factor of the neighbourhood, and temperature difference of urban area from its rural counterparts ( Bardhan, Debnath, Malik, & Sarkar, 2018 ; Mehrotra, Bardhan, & Ramamritham, 2019 ). To factor in the built environment-induced heating of the generated study area (see Fig.…”

“…Suhu merupakan salah satu indikator kenyamanan yang dapat dirasakan pada saat beraktifitas baik di dalam maupun diluar ruangan. Indikator ini disertai dengan kondisi kelembaban udara dapat digunakan untuk mengukur tingkat kenyamanan manusia [8] terutama di wilayah pemukiman dan perkantoran [9]. Pada Wilayah Kalimantan Barat yang masuk dalam iklim tropis, kondisi suhu tubuh manusia secara umum akan selalu berada di atas suhu lingkungan sekitarnya.…”

Tingkat kenyamanan merupakan interaksi antara manusia dengan lingkungan yang berkaitan dengan cuaca dan iklim. Tingkat kenyamanan ini cukup mempengaruhi kegiatan manusia baik di dalam maupun di luar ruangan. Kenaikan suhu yang diakibatkan oleh pemanasan global menyebabkan potensi perubahan tingkat kenyamanan yang dirasakan oleh manusia. Kalimantan Barat yang berada di wilayah khatulistiwa umumnya memperoleh radiasi matahari yang intensif sehingga suhu udara rata-ratanya relatif tinggi. Penelitian ini dilakukan untuk mengetahui tren perubahan suhu dan perubahan tingkat kenyamanan termis akibat perubahan iklim dengan menggunakan humidex di wilayah Kalimantan Barat. Data yang digunakan adalah data suhu dan kelembaban rata-rata bulanan selama 30 tahun di enam stasiun, yaitu Stasiun Klimatologi Mempawah, Stasiun Meteorologi Supadio, Stasiun Meteorologi Sambas, Stasiun Meteorologi Melawi, Stasiun Meteorologi Sintang, dan Stasiun Meteorologi Ketapang. Hasil perhitungan humidex di wilayah Kalimantan Barat menunjukkan rata-rata humidex bulanan berkisar antara 37.5°C hingga 39.2°C. Nilai ini menunjukkan bahwa kondisi tidak nyaman akibat panas sangat umum dirasakan di Kalimantan Barat. Suhu di Kalimantan Barat mengalami peningkatan selama periode 1990-2019. Peningkatan ini mengindikasikan telah terjadi perubahan iklim di Kalimantan Barat. Humidex juga mengalami tren peningkatan pada periode 1990-2019. Namun, tren peningkatan tersebut masih pada rentang kategori “perasaan tidak nyaman akibat panas” (35⁰C - 39⁰C).

“…These programs intensify land utilization by maximizing the number of housing units thereby creating large volumes of construction. Previous studies have demonstrated that these houses modify the thermal budget of the built environment, which in turn will affect the comfort conditions (Mehrotra, Bardhan, & Ramamritham, 2019). If on one side, studies on domestic electricity (henceforth referred to as energy) consumption in India and Ethiopia seem to take the drastically rising demand for granted, on the other side, studies are yet to address the question of 4 thermal comfort and energy demand in these new typologies of housing.…”

Rapid urbanization pressure and poverty have created a push for affordable housing within the global south. The design of affordable housing can have consequences on the thermal (dis)comfort and behaviour of the occupants, hence requiring an occupant-centric approach to ensure sustainability. This paper investigates occupant behaviour within the urban poor households of Mumbai, India and its impact on their thermal comfort and energy use. This study is a first-of-itskind attempt to explore the socio-demographic characteristics and energy-related behaviour of low-income occupants within Indian context. Three occupant archetypes-Indifferent Consumers; Considerate Savers; and Conscious Conventionals were identified from the behavioral and psychographic characteristics gathered through a transverse field survey. A two-step clustering approach was adopted for occupant segmentation that highlighted considerable diversity in occupants' adaptation measures, energy knowledge, energy habits, and their pro-environmental behaviour within similar socio-economic group. Building energy simulation of the representative archetype behaviour estimated up to 37% variations for air-conditioned and up to 8% variation for fan-assisted naturally ventilated housing units during peak summer months. The results from this study establish the significance of occupant factors in shaping energy demand and thermal comfort within low-income housing and pave way for developing occupant-centric building design 2 strategies to serve this marginalized population. The developed low-income occupant archetypes would be useful for architects and energy modelers to generate realistic energy use profiles and improve building performance simulation results.
