This can help to reduce energy consumption for cooling and improve the overall energy efficiency of the building. Additionally, green roofs can also provide other benefits such as reducing stormwater runoff and improving air quality.Rate this question:

You often use a room lit with fluorescent lamps only. Which is the best way to save electricity if you are leaving the room for 10 minutes?
- A.
Switch off the lamp for that 10-minute period
- B.
Leave the lamp on since it does not cost much to have the lamp turned on for 10 minutes.
- C.
Leave the lamp on since the fluorescent lamp uses a large amount of current to re-start
- D.
Either way, there is no difference in the amount of electricity used.
Correct Answer
A. Switch off the lamp for that 10-minute periodExplanation
Switching off the lamp for the 10-minute period is the best way to save electricity because even though fluorescent lamps use a small amount of current to start, the energy saved by turning off the lamp for 10 minutes is still significant. Leaving the lamp on, even for a short period, will still consume electricity unnecessarily.Rate this question:

- B.
It detects changes in infra-red energy (body heat of the occupant) within the coverage area. It operates by the “line of sight” principle.
- C.
It detects a moving object by emitting ultrasonic waves and receiving these reflected energy, just like a bat.
- D.
It detects the door movement when a person enters or exits a room.
Correct Answer
B. It detects changes in infra-red energy (body heat of the occupant) within the coverage area. It operates by the “line of sight” principle.Explanation
The correct answer explains that an occupancy (motion) sensor works by detecting changes in infra-red energy, specifically the body heat of the occupant, within the coverage area. This is done through the "line of sight" principle, meaning that the sensor needs a direct view of the area it is monitoring in order to detect any changes in heat energy. This explanation accurately describes how an occupancy sensor functions to detect motion.Rate this question:

Many of your appliances may be using energy even when they're turned off. This wasted energy, called "standby power loss," is the price of convenience. Guilty appliances include DVDs, electric toothbrushes, cordless phones, instant-on TV sets, and other electronic appliances with remote controls, timers, clocks, or memory. How much does this standby power loss constitute in your total home electronics energy?
- A.
Not significant. Do not worry about it at all
- B.
Can be up to 30%
- C.
Can be up to 2%
- D.
It does not consume electricity at all
Correct Answer
B. Can be up to 30%Explanation
Standby power loss can contribute to a significant amount of energy consumption in your home electronics. It is estimated that standby power loss can account for up to 30% of your total home electronics energy. This means that even when your appliances are turned off, they may still be using a considerable amount of energy. Therefore, it is important to be mindful of this standby power loss and consider ways to reduce it, such as unplugging appliances when not in use or using power strips with on/off switches.Rate this question:
