HVAC is one of the significant operating expense in a laboratory. Laboratories can benefit from designing their capacity properly, right at the planning stage, and making provisions for expansion with no costly alterations. 

Diversity is a design paradigm which will help to build optimal laboratories. According to SEFA, “Diversity is used by engineers in designing systems based on its practical or maximum expected use, not its total possible use. When diversity is applied to sizing of systems, the design capacity is less than the sum of peak demands”. 

Diversity can benefit both the existing and new facilities:

  • reduce capital equipment expenditures by downsizing the mechanical systems during the design phase,
  • allows existing facilities to add fume hood capacity using the current HVAC systems.

The key factors influencing diversity are:

Mechanical systems
  • Control Method
  • Constant Volume CV
  • Variable Air Volume VAV
  • Two State Controls
Usage Pattern
  • Number of users per fume hood
  • Fume hood usage type
  • User compliance
  • Sash type
  • Sash management
Airflow Requirements
  • Face velocity
  • Cooling airflow rate
  • Minimum ventilation rate
Number of Floors and Size of Building
  • Fume Hood Density
  • Number of fume hoods per lab
  • Number of fume hoods per manifold.
