AERO VENT ng Testeelfy. Ang malaking pagkakaiba ay exhaust-only vs. complete passive ventilation system.

1. Exhaust lang para sa attic
Ang exhaust fan o exhaust opening ay pangunahing naglalabas ng mainit na hangin sa attic.

Problema: Kung walang sapat na papasok na hangin, limitado ang dami ng hangin na mailalabas. Parang humihigop ka ng hangin sa isang saradong kahon.

Resulta:
Mainit na hangin → palabas
Kaunting fresh air → papasok
Mas dependent sa fan/wind conditions kung mechanical exhaust

2. Roof vent / passive vent
Ang magandang roof ventilation system ay may airflow path:

Fresh air IN → attic → hot/moist air OUT

Ang advantage ng vent ay hindi lang basta "butas sa bubong." Kapag tama ang placement at may intake + exhaust pathway, tuloy-tuloy na napapalitan ang hangin sa attic gamit ang natural movement ng mainit na hangin at pressure differences.

Kapag kulang ang ventilation sa bahay, lalo na kung walang roof vent, naiipon ang mainit at maruming hangin sa loob, at puwedeng makaapekto sa comfort at indoor air quality.

🌡️ Ano ang puwedeng mangyari?

1. Mas mainit ang loob ng bahay

- Naiipon ang init sa ilalim ng bubong at kisame.
- Lalo itong ramdam sa tanghali hanggang hapon.

2. Mas kulob at mabigat ang hangin
- Hindi maayos na nailalabas ang mainit na hangin.
- Puwedeng maging uncomfortable ang pagtulog o pagtira sa loob.

3. Mas mataas ang humidity
- Kapag hindi nailalabas ang moisture, mas madaling magkaroon ng condensation, amag at mildew, depende sa kondisyon ng bahay.

4. Mas madaling mangamoy kulob
- Ang stagnant air ay maaaring magpanatili ng amoy mula sa pagluluto, pawis, moisture at iba pang indoor sources.

5. Mas nahihirapan ang aircon
- Kung mainit ang attic/roof space, mas maraming heat load ang kailangang labanan ng aircon.
- Kaya maaaring mas matagal mag-cool down ang room at mas mataas ang electricity consumption.

6. Puwedeng makaapekto sa comfort at well-being
- Ang sobrang init at poor indoor air quality ay maaaring magdulot ng discomfort, pagod, pananakit ng ulo o hirap makatulog sa ilang tao, lalo na kapag napakainit ng panahon.

🏠 Dito pumapasok ang roof vent

Ang roof vent ay tumutulong maglabas ng naipong mainit na hangin sa roof/attic area, habang dapat may sapat ding intake openings para makapasok ang replacement air.
