HRV
HRV (Heat Recovery Ventilation) is a building system that helps make buildings more energy-efficient and comfortable. It's like a smart ventilation system that brings fresh air in while saving energy. When stale air leaves the building, the HRV captures its heat and uses it to warm up incoming fresh air, saving on heating costs. Think of it as a way to keep fresh air flowing without wasting energy. You might also see it called "heat exchanger," "energy recovery ventilator," or "mechanical ventilation with heat recovery." It's an important part of modern green building design and is often mentioned in job descriptions related to sustainable construction and building efficiency.

Example Interview Questions
Senior Level Questions
Q: How would you approach designing an HRV system for a large commercial building?
Expected Answer: A strong answer should cover assessing building size and usage, calculating ventilation needs, considering climate factors, planning for maintenance access, and explaining how to maximize energy efficiency while meeting fresh air requirements.
Q: What factors do you consider when recommending HRV vs ERV systems?
Expected Answer: Should discuss climate considerations, building usage patterns, humidity control needs, and cost-benefit analysis, explaining these technical concepts in clear terms that clients can understand.
Mid Level Questions
Q: How do you ensure proper maintenance of an HRV system?
Expected Answer: Should describe regular maintenance schedules, key components to check, filter replacement, cleaning procedures, and how to identify common problems before they become serious.
Q: What are the main benefits of HRV systems in green building projects?
Expected Answer: Should explain energy savings, improved air quality, reduced heating/cooling costs, and contribution to green building certifications like LEED points.
Junior Level Questions
Q: Can you explain the basic principle of how an HRV works?
Expected Answer: Should be able to explain in simple terms how the system transfers heat from outgoing to incoming air while keeping the air streams separate, and why this is important for energy efficiency.
Q: What safety considerations are important when working with HRV systems?
Expected Answer: Should mention electrical safety, proper installation procedures, ensuring correct airflow directions, and importance of following manufacturer guidelines.
