1. TRADITIONAL BAHAY KUBO
The Bahay Kubo serves as an example of this by having large windows placed in strategic
parts of the building for natural ventilation. Large windows, ventanillas or louvers, and a hot air
exhaust pipe at the peak of the ceiling are a few other examples of openings that allow wind to
move through the house. Furthermore, the entire house as well as its surrounds are shaded by the
wide roofs and overhangs. When the location enables, properly orienting the home to open up to
the wind directions may also be significant. When this is done, light is still welcomed yet heat is
reflected away from the dwelling.
2. MODERN HOUSE
Passive cooling meets a home's cooling, ventilation, and lighting needs by utilizing free,
renewable energy sources like the sun and wind. By using passive cooling, a building can be made
more livable and comfortable for workers and residents by reducing the gap between indoor and
outside temperatures and enhancing indoor air quality. A louvered shading device was placed in
the building to prevent summer solar gain while also allowing wind to pass through and cool the
space. The shade is made to shield the sun in the summer while allowing it in during the winter. Low
emissivity coating can be utilized to lower interior temperatures as well as heating and cooling costs
to lessen heat transmission.
3. CONCLUSION
In a passive cooling design, it is important that all main elements of the building should
either block or reject solar heat gain and try to keep the building cool against the heat of
summer which Bahay Kubo is a suitable representation of a green building. We can learn
from it that we can somehow find ways to balance the aesthetic and functionality of a
space by reducing the use of concrete. It prioritizes natural lighting and ventilation to
passively cooled the living space. While modern houses puts mechanical system, so this load
could be reduced by adding elements to the building, such as louvered shading devices
which can significantly reduce energy consumption and have cross ventilation. The same
principles from the bahay kubo can be applied to a modern house and it will also get the
same wind flow and heat protection.
