House Tightness, Environmental Control and Energy Usage
The more control producers have over air temperature, air quality and energy usage, the more control they will have over their paycheck at the end of the growout. In order to control air temperature, air quality, and energy usage, it is crucial to control how much fresh air enters the house as well as how it enters the house. This means a house must be tight, because in a loose house it is very difficult to control anything. This is true whether we are talking about the hottest day of the year with market age birds or the coldest day of the year with day-old-chicks.
