The heat is the biggest problem the residents in the tropic have. The heat and if you live in the wet zone, the humidity are killer elements which significantly harm the home and its resident’s comfort. While using mechanical systems for controlling this was an option in the past, it is no longer a viable source anymore. Authorities have understood the significant environmental issues associated with extensive use of energy for cooling and are imposing regulations and taxes on the people in order to discourage the use of mechanical cooling systems. Passive cooling systems are however encouraged.
Passive cooling is the use of natural ventilation, shading, building orientation and various materials to keep interiors cool. Orienting a building in the correct direction which reduces the amount of heat gain and allows proper use of ventilation can reduce the heat buildup within the building by a few degrees and can help control the temperature levels inside. While these techniques and materials may sometimes be more expensive at its inception, the cost reductions as a result through the lifetime of the building more than make up for it. For example, double glazed door prices are slightly higher than the single pane doors. Take a look at this page to find out the right double glazed door.
But would you ever opt to have ordinary windows when you can have sound proof windows living next to a fraternity house? This is the same. While the initial cost is a little higher, the long term benefits are far greater.
Use of Ventilation
If you are living in a hot humid climate, it is always best to promote cross ventilation within the building to remove the hot humid air through the day. However, in a drier climate where the night air is cooler than the day, a building form of a doughnut which does not allow cross ventilation, rather has a cooling system through a central courtyard is better. In a wetter region, the houses will thus be more outward looking with windows on all sides. In a dry climate, the house will be more introverted with small openings to the outside and everything centrally connected and ventilated in the night through the courtyard. A house meant for cross ventilation in a dry zone will only result in bringing the warm air in during the day and will not retain the cool air of the night within the house to tackle the heat during the day. Thus, making sure you know and understand the requirements of the climate you live in is important to keeping your home cool and comfortable.
