Specifying a Climate-Controlled Poultry House in a Hot Climate
Design temperature, airflow, cooling pads, insulation and alarms: how to specify a closed poultry house so quotations are technically comparable.

In short
Short answer. A closed poultry house is specified from four numbers: design ambient temperature and humidity, stocking density, target bird weight at the end of the cycle, and minimum acceptable air velocity. Everything else — fan count, pad area, heater capacity, controller specification — follows from those.
Key takeaways
- Maximum ventilation rate is a function of bird mass and design temperature; minimum ventilation is a function of moisture and CO2 removal in cold conditions.
- Evaporative cooling capacity depends on ambient wet-bulb conditions, not on dry-bulb alone; in humid coastal climates pad cooling delivers far less than in dry inland sites.
- Backup ventilation on power failure, curtain drop systems, alarm and SMS notification, sensor redundancy, static pressure control, insulation U-value, and inlet distribution.

Start with airflow, not with fans
Maximum ventilation rate is a function of bird mass and design temperature; minimum ventilation is a function of moisture and CO2 removal in cold conditions. Size both with the ventilation calculator, and check stocking assumptions against the bird density calculator.
Cooling, heating and the energy consequence

Heating load in brooding is often underestimated in tropical projects with cool nights. Both convert directly into running cost — quantify them with the poultry house energy calculator.
The items quotations usually omit
Backup ventilation on power failure, curtain drop systems, alarm and SMS notification, sensor redundancy, static pressure control, insulation U-value, and inlet distribution. The full specification checklist is in the poultry house climate control guide.
Put the resulting figures into the brief described in the commercial poultry project RFQ process, and budget the package using the poultry farm CAPEX guide.
