Fume hoods are literally huge energy spenders, with each one consuming more energy than three average homes in the US. You gotta watch this video which pretty summarizes how this problem can be addressed. Check it out!
Based on the video shown above, here are the hard facts:

Based on the video shown above, here are the hard facts:
- Estimated annual energy consumption for conventional fume hoods is around US$9,000 based on face velocity of 0.5 m/s (100 fpm) at full sash open position for 1.8 m (72”) hood.
- The annual energy consumption of a conventional hood is equivalent to the consumption of around 3 average homes in the US.
- A new line of high performance, low-flow fume hoods were engineered to help reduce energy consumption. These efficient hoods operate safely at a reduced face velocity of 0.3 m/s
- With the reduced face velocity, energy consumption can also be reduced dramatically .
- In using a high performance hood, it is estimated for the exhaust volume to be reduced by 58%. This translates to an annual savings of US$ 5,600.
