“…An estimation of the temperature of the supply and exhaust air after passing through the heat recovery is made from the relevant ventilation design, and all the parameters refer to external calculation conditions. The temperature of the air supply can only take into account the increase in temperature through heat recovery and does not take into account the increase in temperature from active preheating (Vargová et al, 2021;Kumar et al, 2022;Li et al, 2022).…”

The case study analyses a specifically described situation from the present and a summary of events from the past, finds alternative solutions, and decides on one of them. The target of such a detailed analysis was a concrete apartment building, which was still in the project phase; the efforts to change its proposed air conditioning system to a more energy-efficient one are the subject of the case study. Apartment buildings with modern technology installed in terms of sanitary equipment, heating, and simple methods of ventilation and cooling do not constitute part of the project. Through a detailed analysis of the calculation of the heat losses through ventilation in the case of local and decentralised ventilation applied to one apartment unit, this failure to address modern solutions is remedied.

“…Salah satu upaya untuk menurunkan konsentrasi PM2.5 dan PM10 di ruang tamu akibat aktivitas merokok di lingkungan rumah adalah dengan memasang ventilasi mekanik (exhaust fan) di salah satu sisi dinding kamar tamu tersebut. Secara teoritis penggunaan ventilasi mekanik dapat mengurangi konsentrasi polutan cukup signifikan di dalam suatu ruangan (Kumar et al, 2022).…”

Udara bersih adalah kebutuhan dasar untuk menjamin kesehatan bagi penghuni rumah. Asap rokok adalah salah satu polutan yang sering berada di rumah. Efek negatif dari asap rokok pada kesehatan telah dilaporkan oleh beberapa ahli. Namun, hingga saat ini, masih banyak dijumpai perokok yang merokok di tempat sembarang di sekitar rumah, seperti di teras, di dalam ruang tamu dan di kamar mandi. Perilaku ini akan berdampak buruk bagi kualitas udara di dalam rumah. Partikulat berdiameter kurang dari 2.5 µm (PM2.5) dan kurang dari 10 µm (PM10) adalah salah satu polutan utama yang dihasilkan oleh asap rokok. Berdasarkan beberapa penelitian, melaporkan bahwa selain akan mengendap di paru-paru, PM2.5 dan PM10 dapat menyebabkan beberapa penyakit, antara lain asma, ISPA (infeksi saluran pernafasan akut), kanker paru-paru dan meningkatkan tingkat mortalitas. Pada penelitian ini dilakukan pengukuran PM2.5 dan PM10 di dalam ruang tamu akibat perokok yang merokok di kamar mandi, di dalam ruang tamu dan di teras. Pengukuran konsentrasi PM2.5 dan PM10 dilakukan di rumah dengan luas sekitar 45 m2. Pengambilan data dilakukan sebelum merokok, 15 menit setelah rokok dinyalakan, 30 dan 60 menit setelah rokok dimatikan. Berdasarkan pengukuran didapat bahwa konsetrasi PM2.5 dan PM10 di ruang tamu akan meningkat di atas baku mutu untuk semua lokasi merokok di area rumah. Meskipun perokok merokok di teras dengan pintu ruang tamu tertutup, konsentrasi PM2.5 dan PM10 di ruang tamu tetap meningkat, dari yang sebelumya 27 dan 68 µg/m3 menjadi 63 dan 127 µg/m3. Dari penelitian ini didapat kesimpulan bahwa meskipun merokok di luar rumah, dengan pintu tertutup, tetap dapat meningkatkan konsentrasi PM2.5 dan PM10 di ruang tamu jauh di atas di atas baku mutu. Tentu saja hal ini akan berdampak buruk bagi seluruh penghuni rumah.

“…Another significant aspect of a healthy and comfortable building design is the availability of an adequate ventilation system. In buildings, ventilation functions for circulation and air conditioning to keep the rooms fresher, healthier, and more comfortable [16], [17]. The stale and warm air inside the room must be vented outside to replace it with cooler and cleaner air.…”

This study investigated the cooling effect of an Earth Water-Air Heat Exchanger (EWAHE) device for ventilation applications. To address the lack of data on EWAHE performance in moderate climates, we measured temperature parameters (inlet-outlet, indoor-outdoor, water, and soil) continuously for three days. Air temperatures, air flowrate, light intensity are measured using a multi-channel data logger with several sensors. Results showed that the EWAHE effectively reduced indoor air temperature by an average of 7.5°C with a maximum reduction of 9.3°C, offering a promising passive cooling solution for buildings. The primary limitation of this study is that it requires open space around the building to place the device, so this method is inappropriate for building in a dense urban area. Future studies could investigate the association between ground-water cooling effect and natural ventilation without using energy for air circulation.
