Ventilation Energy Self Assessment
The Ventilation Energy Calculator evaluates your current ventilation equipment for exhausting air from a building or circulation fans for cooling animals. For exhaust fans, the assessment tool compares your current high speed fans to high efficiency high speed fans and the use of thermostats to reduce energy consumption. An efficient high speed fan will have been tested by an independent lab and have an efficiency rating of 21 cubic feet per minute or higher for a 48” exhaust fan. If you are using or considering high speed fans for circulation, the tool evaluates the use of high-volume low-speed (HVLS) overhead paddle fans for air circulation to high-speed fans. The HVLS fans can move large amounts of air with less power than high speed fans. This module will aid you in identifying opportunities to reduce your energy consumption. Allow 10 to 15 minutes to complete plus time needed to collect any unknown data.
