4.5. Efficient Ventilation

Try these first

1. 1.

   What is the primary function of ERVs?

   Hint

   Focus on the concept of energy exchange.

2. 2.

   True or False: HRVs can control humidity.

   Hint

   Think about the features of HRVs.

3. 3.

   What is the function of an Energy Recovery Ventilator (ERV)?

   • A. Filters air
   • B. Recovers energy
   • C. Controls humidity

   Hint

   Think about how energy is used in a building.

4. 4.

   True or False: HRVs are effective in humid environments.

   • True
   • False

   Hint

   Consider the limitations of HRVs.

5. 5.

   A new office building is located in a cold climate. Discuss the ventilation system design considering the use of HRVs. How would this design enhance energy efficiency?

   Hint

   Consider the concept of heat transfer and energy savings.

6. 6.

   Evaluate the potential impact of poor ventilation on energy consumption and indoor air quality in a high-rise residential building. Provide a strategy with ERVs to counteract this.

   Hint

   Reflect on the balance between air quality and energy efficiency.
