What does geothermal heating and cooling utilize for temperature control?

• Wind energy
• Sunlight
• Soil temperature beneath ground
• Building insulation

Answer explanation

Geothermal systems use earth’s stable underground temperature.

What is the function of a HEPA filter in green buildings?

• Heat indoor spaces
• Trap air pollutants and allergens
• Generate electricity
• Maintain plumbing systems

Answer explanation

HEPA filters capture 99.97% of particles ≥ 0.3 microns to improve air quality.

How do CO₂-controlled ventilators work in buildings?

• Use room temperature
• Use carbon monoxide readings
• Adjust airflow based on occupancy
• Replace air conditioning

Answer explanation

These systems detect CO₂ levels to adjust ventilation, saving energy.

What is a key benefit of installing solar panels on a building's roof?

• Increases water storage
• Lowers energy bills by using sunlight for electricity
• Helps collect rainwater
• Improves waste management

Answer explanation

Solar panels reduce reliance on grid power by generating renewable energy.

What do solar thermal collectors primarily do?

• Light indoor spaces
• Heat water using sunlight
• Purify drinking water
• Store energy in batteries

Answer explanation

Solar thermal panels directly heat water using solar radiation.

What kind of water is reused in green buildings for flushing and gardening?

• Rainwater
• Tap water
• Greywater
• Blackwater

Answer explanation

Greywater from sinks/showers is treated and reused for non-drinking purposes.

Why are LEDs preferred in green buildings?

• Shorter lifespan
• Higher energy use
• Lower power consumption and less heat
• More stylish look

Answer explanation

LEDs use less power and emit less heat, reducing cooling load.

Where are wind turbines most effective for electricity generation?

• On the ground next to buildings
• Inside buildings
• On top of tall structures where wind is stronger
• In underground ducts

Answer explanation

Wind turbines work best at height due to stronger and more stable winds.

Which of the following is NOT a benefit of a green building?

• Reduced energy use
• Better indoor air quality
• Increased environmental impact
• Healthier occupant comfort

Answer explanation

Green buildings are designed to minimize environmental impact, not increase it.
