artificial lighting systems
The concept of non-architectural approach is focused on the use of technologies that can utilize the excess heat in the tropics. This tool is in the form of solar panels (photovoltaic panels), ie a panel, which is placed in the roof (Building Integrated Photovotaics) or in the yard, which can absorb and store heat energy generated by solar heat. Heat energy stored by solar panels is converted into electrical energy which can then be used to power electrical devices, artificial lighting and artificial primarily on the use of night. During the day and lighting system is more focused on natural approaches (natural cooling and lighting). The problem is the procurement of solar panels is also not cheap. But for the long term solar panel is very effective for saving energy.
As for artificial lighting systems, use energy efficient lights can help reduce energy consumption. The definition of light energy is the use of lights that have a high efficacy rate, which means having high levels of light illumination (Lux) / watt. Therefore the use of SL type lamps with low wattage (8-11 watts) but has a level of illumination 560-770 Lux highly recommended. Level of illumination was sufficient for everyday activities ranging from 150-400 lux. Advantages of the use of energy-saving bulbs is no effect on space heat.
