Federal Government Campus Improves Ventilation
A Civilian Conservation Corps camp in the Great Depression has done limited upgrades as budgets permitted. Each 6,000 ft2 dorm building was previously ventilated only when the forced air heating furnaces operated. No mechanical ventilation operated in the summer and shoulder seasons, and it was intermittent in the winter, greatly impacting sleeping conditions. With the focus on healthy levels of CO2, optimal heating system improvements were not done in this pilot. To solve the recurring nightly unhealthy levels of CO2, one HRV per dorm was installed, four in total. The HRV is programmed with a combination of demand-based controls via a CO2 sensor within a certain PPM range, programmed with time / day-of-week scheduled operations. This will ensure healthy levels of CO2 for residents.
