LED efficacy as key indicator to evaluate bulb lighting

Effect of urban built form and density on building energy performance in temperate climates

“…To calculate the lighting energy demand, a mean value of 300 lux is considered for the whole block. A high-efficiency model of LEDs (140 lm/W) is chosen [73], giving a mean power consumption of 2.14 W/m 2 . Typical consumptions of common home appliances are given in Table 1.…”
