The easiest solution is to install a cool room air conditioner. In addition, there is another solution that is more efficient and environmentally friendly.

The room was hot certainly not comfortable to live. Most simple solution and quick fix is to install air-conditioning (AC). Many people choose this quick way, without feeling the need to know the root of the problem.

According to Ir. Sukendro Sukendar, architect of Nataneka Architects, the room was hot can be caused by many things. The lack of openings or ventilation is the most common cause. Due to minimal amount of ventilation, no air exchange from inside to outdoors. This is what causes the temperature of the room was hot.

Then, if a window in each room is enough? The answer is no. According Sukendro, for the exchange of indoor air runs good, needs to be made cross-ventilation (cross ventilation). There are at least two windows or openings that face each other in one room.

Cross ventilation allows air to flow from inside to outside and vice versa, without having to settle first, in the room. Air enters from one window, will be directly channeled out by the window in front of him, and replaced with new air, and so on. Thus, without any air conditioning equipment room was cool.

Another thing to consider is the size of the window or opening, which must be balanced with the size of the room. Large room is certainly require a large opening as well. Not only create better air flow, large openings also include a lot of sunlight. The room became healthy and bright, without the need to turn on the lights in the daytime.
