Course Description: AEC Daily: Heat Recovery Ventilation: Why Efficiency Matters
In the last couple of decades, houses have become progressively more airtight due to energy efficiency and cost concerns. While air infiltration and exfiltration rates have been significantly reduced, the need for an efficient ventilation system has become extremely important. This course evaluates different types of mechanical ventilation systems and discusses why heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems are characterized by a high level of energy efficiency and as an effective means for improving indoor air quality.
Identify the advantages and weaknesses of supply, exhaust, and balanced ventilation systems to show how mechanical ventilation systems impact our energy consumption and the air we breathe.
Examine HRV/ERV system configurations to determine the role of an HRV/ERV system in creating an energy-efficient home.
Cite case studies and discuss how HRV/ERV systems maintain healthy indoor air conditions in different climatic conditions and geographic locations with variations in occupancy.
Discuss the importance of planning an HRV/ERV system installation, and review balancing, commissioning, and maintenance considerations to ensure efficient system operation.
