Indoor Air Quality (IAQ) and HVAC Systems

Context

Purpose: Adequate fresh air circulation and removal of stale air.
ASHRAE: Emphasizes the importance of proper ventilation.
Standards:
- Meet building code minimum outdoor air ventilation rates.
- Ensure exhaust systems are exchanging the proper amount of air.
Professional Help: Engage a test and balance professional.
Recommendation: 4 to 6 air changes per hour.
Energy Concerns: Offset increased consumption with energy recovery ventilators (ERV) and improved building envelope performance.

Function: Filters trap particulates and contaminants.
Maintenance: Regularly replace filters to avoid overload.
ASHRAE Guidance:
- Use MERV 13 filters, or at least MERV 11.
- Higher MERV ratings capture more particles, including bacteria and virus carriers.

Analogy: Similar to car inspections or medical check-ups.
Scope: Includes checks on temperature, thermostats, cooling systems, electrical connections, etc.
Service Agreement: Ensure it includes comprehensive inspections and performance level assessments.

Impact: Affects productivity, concentration, and immune system efficiency.
Considerations: Implement good thermostat systems or building automation systems.
Goal: Maintain climate within a specified range suitable for occupants.

Initial Approach: Understanding building systems and space utilization.
Benefits of Good IAQ:
- Increased productivity and happiness of occupants.
- Avoidance of costly repairs and legal issues.
