ASHRAE 90.1 / 62.1 (referenced)

Energy and ventilation standards referenced for agricultural building design

Issuer: ASHRAE

US-origin engineering references for energy efficiency (90.1) and ventilation for acceptable indoor air quality (62.1) — frequently referenced in EPC specifications for poultry buildings even outside the US.

Applies to

  • Poultry house ventilation and insulation design
  • Hatchery HVAC design
  • Processing plant HVAC and refrigeration engineering

Key requirements

  • Envelope thermal performance (U-values, insulation continuity)
  • HVAC equipment efficiency minimums
  • Ventilation rates and air-quality provisions
  • Commissioning and measurement provisions

How buyers cite this in procurement

Referenced in engineering specifications for hatchery and processing HVAC where local code is silent, and to benchmark envelope performance of new poultry houses in colder climates.
