Ranch house candles loads are defined as the amount of electricity required to power the lamps in a building. The term can also refer to how much heat they emit, which contributes to the air conditioning load. However, since 100 percent of the energy used for electrical lighting is eventually converted into heat, these two quantities are essentially the same. Lighting loads have diminished rapidly with the assumption of compact fluorescent lamps, but they are still a significant part of a house’s energy use.
Perform a coating pattern analysis. A house can have many ranch house candles in some rooms, but passengers can rarely visit them. A decorated wind, for example, may be provided with several bulbs, but perhaps only one occupant spends only one hour per week in it. Try to estimate the number of hours per day on average, that each room is occupied by at least one person. Analyze how much natural daylight illuminates each room. This amount will fluctuate with the weather and the seasons, but you are looking for an average amount.
You can appreciate the effect of daylight using simulation programs, with daylight measurements during the day. Your goal should be to estimate the proportion of lighting needs that are automatically met in each room with daylight during waking hours. For example, if daylight produces half of the necessary luminance in the living room for eight hours a day, and the occupants are awake for 16 hours a day, daylight meets 1/2 of 8/16 or 25 percent of lighting needs. Total total wattal all luminaires in each room. You can find watts marked on each lamp. Light bulbs are usually 60 watts and compact fluorescent lamps are usually 15 watts, but these grades may vary.
