Operating a building with laboratory exhaust systems can be a large initial and ongoing investment. Ensuring that the systems are functioning efficiently without compromising occupant health or operational effectiveness is crucial.
Use of variable air volume (VAV) air handling systems can efficiently control the outside air that is conditioned and brought into a space. However, most exhaust systems paired with VAV supply systems use constant volume exhaust fans with bypass dampers. This means savings opportunity is left on the table while energy and money are wasted.
We aim to maximize energy savings by analyzing the exhaust system effectiveness and define the minimum airflow requirements so each exhaust fan can run at less than 100% of design load while still maintaining required performance. This provides a more efficient system and significant energy savings, including the ability to save money by spreading the exhaust load for existing N+1 systems across all available fans.
CPP wind has extensive experience designing and implementing VAV exhaust control strategies. With more than 300 installed systems throughout the Unites States, Canada, and the United Kingdom, we can help you design a more efficient system and save money in the process.
