“…Evaporative cooling pada louver sebagai strategi desain pasif pada bagian yang terekspos dengan arah masuk angin (utara). Strategi ini dapat bermanfaat untuk memberikan pembayangan dari radiasi matahari, menyediakan radiative cooling dari pendinginan louver ke dalam bangunan, menyediakan pendinginan melalui penghawaan dengan bantuan pergerakan angin [16] [29] [30] [31] [32] . Penggunaan evaporative cooling ini perlu dipertimbangkan kembali karena akan mengurangi nilai bersejarah bangunan karena menutupi fitur-fitur bersejarah pada Gereja GPIB Immanuel Malang.…”

Selaras dengan salah satu tujuan dari pembangunan berkelanjutan dalam bidang pemukiman (habitation), yaitu membangun kota dan permukiman yang inklusif, sehat, aman, awet, dan berkelanjutan, maka kualitas lingkungan yang baik menjadi penting. GPIB (Gereja Protestan di Indonesia bagian Barat) Immanuel Kota Malang merupakan bangunan cagar budaya yang berada di daerah beriklim tropis lembap, di lingkungan perkotaan padat bangunan. Tujuan dari kegiatan pengabdian pada masyarakat ini adalah menyelesaikan permasalahan yang disampaikan oleh Mitra GPIB terkait kondisi tempat ibadah yang tidak nyaman secara termal. Metode pengabdian pada masyarakat dilaksanakan dengan pengukuran, simulasi/ perhitungan, dan analisis termal eksisting yang diselesaikan dengan pemasangan pengkondisi udara, namun masih ada keluhan penataan yang harmonis dan estetis. Hasil dari kegiatan ini berupa rancangan usulan perbaikan kondisi lingkungan di ruang ibadah. Seiring dengan program pengembangan sarana dan prasarana ibadah sebagai bangunan cagar budaya, peningkatan kondisi lingkungan diutamakan dengan mempertahankan kualitas sebagai bangunan yang dilindungi pemerintah.

The optimal shading system plays a significant role in a sustainable environment in controlling the amount of excessive sunlight and reducing the thermal discomfort of occupants. External shading device requires many design considerations such as solar altitude, control strategies, and aesthetics to control solar gain, improve the visual environment and reduce glare. Proper external shading design can reduce cooling energy consumption and prevent an overheated indoor environment. This paper focuses on the performance of the Wind-Catcher shading device on the residential house in a hot and humid climate. This study focused on the effect of using Wind-Catcher shading devices on indoor thermal comfort. It proposes solar shading and wind catching design and its performance compared to other types of external shading devices. One of the residential houses in a hot and humid climate is taken as the representative study house of the research. The theoretical and analytical approach will analyze three types of shading devices, such as overhang, box-type shading devices, and wind-catcher shading devices, to validate and compare the shading magnitude amount. The result indicates that the Wind-Catcher shading significantly reduces thermal discomfort hours and allows moderate wind flow into the room rather than other shading types.

“…External shading is the most effective method to control the solar heat gain [42,43]. Using different forms of shading devices can effectively reduce the cooling load [44][45][46][47][48], thereby reducing the total energy demand [49]. In Turkey, a total of 1485 scenes were created using fixed external shading devices with the coordination of parameters such as orientation, glass type, WWR, shading device depth, and slope.…”

The role of the transparent envelope in energy savings is crucial as it accounts for a significant proportion of the total energy loss (between 30 and 40%). This paper focuses on the identification of reasonable parameters for the transparent envelope in different climatic regions. To achieve this goal, typical urban office buildings from four different climatic regions are used as research objects. A total of 1600 scenarios were simulated to investigate the variation of energy use intensity, including transparent envelope parameters, meteorological parameters and different types of glazing. The results show that for south-facing transparent envelope facades, type D glazing is the most energy efficient in severe cold regions, type C in colder regions and type B in the other two climatic regions. No solar shading is required in the very cold region. Horizontal shading can be an effective method for saving energy in colder climates, while comprehensive shading can be beneficial in other regions. Deep shading is particularly energy efficient if it meets lighting requirements. For example, in Guangzhou, energy savings of 13.46%, 15.47%, 7.01% and 7.02% can be achieved in the east, west, south and north directions, respectively, using B-type glazing and a comprehensive shading depth of 900 mm.
