How do motion sensor lighting controls help in energy conservation?

• Motion sensor lighting controls help in energy conservation by turning lights on or off based on occupancy, reducing unnecessary energy consumption.

• Motion sensor lighting controls increase energy consumption by keeping lights on constantly.

• Motion sensor lighting controls have no impact on energy conservation.

• Motion sensor lighting controls only work during the day, wasting energy at night.

What is the concept of lighting retrofits for energy savings?

• Lighting retrofits involve adding more energy-consuming fixtures

• Lighting retrofits are only applicable to residential buildings

• Lighting retrofits do not impact energy consumption

• The concept of lighting retrofits for energy savings is to replace older, less efficient lighting systems with newer, more energy-efficient options.

Why is natural light utilization important in energy conservation?

• To reduce the need for artificial lighting and lower energy consumption.

• To increase the need for artificial lighting and raise energy consumption.

• To promote the use of energy-intensive artificial lighting.

• To create a cozy atmosphere indoors by limiting natural light.

What are the key benefits of using LED lighting technology?

• Shorter lifespan, high energy consumption

• Fragile, limited applications
