When building, buying, or renting a home, to consider the efficiency of energy use in the home that will dihunii. Energy efficiency have much effect on the costs incurred for the use of electricity, water, repairs, etc. Efficient energy consumption also helps businesses mitigate global warming, because in the long run will reduce the amount of carbon dioxide released into the atmosphere; considering that most of the power plants still use fossil fuels.
The area has a tropical climate, energy consumption for households is actually not as complex as in the subtropical region. Almost all the houses and buildings in Indonesia does not require heating, and air conditioning is only needed in low-lying areas were pretty hot. Stable temperature throughout the year both day and night, and the sun is also abundant with different time and temperature on the time of day or night is also not much different. This is different from the subtropical region. In winter, a lot of energy is used to heat the room. By contrast, in the summer, the use of air conditioning (AC) increases when the temperature shot up. The time difference of day and night during the winter and summer also affects the energy consumption for lighting.
For home Design efficient in using energy, the following points should be noted:
1. Natural lighting in daylight
Continued abundant sunshine throughout the year in Indonesia. Thus, with the lamp lighting is not needed during the day. With the proper installation of the windows on all the space there will be energy efficiency, because there should be no use of lights when the sun is still shining.
2. Installation of energy saving lamps
The use of energy saving lamps will be very helpful. Energy-saving lamps require lower power but the light produced brighter. Energy saving lamp converts electrical energy into light energy, and only a little is wasted into heat.
3. The layout of the lights and the interior of the house
A well placed lights will illuminate the entire room perfectly. Generally, the lights are located in the center of the room will illuminate the entire room with a better corner. Whitewashed room will seem brighter lights used despite lower power, because the white color reflects light more.
4. Ventilation and wall insulation
Ventilation will help remove the hot air from the room. Wall construction should use materials that do not absorb heat. Paint bright colors will help reflect light and heat well. Good ventilation and insulation will help reduce the use of fans and air conditioning (AC).
5. Nice rooftop does not absorb heat
The roof tiles are better than asbestos or corrugated iron roofs. Roofs painted white to reflect heat better. In contrast, asbestos and zinc absorb heat and make the temperature in the room rises quickly.
6. The energy-efficient electrical equipment
Electrical equipment that uses low power necessarily better. Automatic electrical equipment could be the right choice, because it can stop working automatically to the time the work is completed. There need be no energy is wasted, if the tool can be set to off or standby when not in use.
Efficient energy consumption of more environmentally friendly. Another benefit that is felt immediately decreasing the cost of bills to be paid every month. Designing homes that use energy efficiently is easier in the tropics.
