Low energy ventilation 27th february 2014

Many air handling units supply a volume of fresh air into a building at a constant rate and consume a considerable portion of the building energy. This rate was determined during the design stage originally to provide enough fresh air per person and to deal with a number of other environmental factors. Perhaps it is time to reassess this set-up and take advantage of energy saving opportunities.
In the last session of our six-part series, we will be sharing our experiences and the approach our clients are using to save energy associated with their ventilation systems.
We have also teamed up with Chris Mulholland from Critical Airflow, who will be presenting data and case studies from a number of projects on "demand-based" ventilation control systems.
There will also be a demonstration on how the Workplace Footprint Tracker can be used to build the case for upgrading ventilation systems and to track savings.

Today's Topic
The functions of a ventilation system to supply sufficient fresh air
to provide adequate indoor air quality by removing and or diluting pollutants from occupied spaces
to provide a heat transport mechanism.

Heating and Cooling?
There are situations where heating and cooling are running at the same time
Common to open up the dead band – but what does this save
A BMS is used to apply the controls however Metering is perfect to measuring the actual outcome
Source Cabon TrustHeating and Cooling and Air Conditioning
What about the Filters?
What about the Filters?
What about Humidifiers?
If you have to use them make sure they run on Gas
Conclusion? Fit metering to manage savings
