Building HVAC Science

Aug 9, 2019

To keep the body in good health is a duty…otherwise we shall not be able to keep our mind strong and clear.


HVAC and building performance contractors are seeing more homes built or retrofit to tighter levels. Blower door test outs like 3, 2, 1 ACH50 or less.


What do you do when the “house can’t breathe?”


Hopefully, you see the humor in that statement.


Of course - you build it tight and ventilate it right! 


(Credit for that phrase likely goes to Earle Perera and Lynn Parkins as the title for their article in the June 1992 Building Services Journal a UK publication)


Listen in as Ty Newell founder of BuildEquinox shares with us how he got to the point of feeling the need to create his own ventilation product, the CERV2: Conditioning Energy Recovery Ventilator.


This unique product senses when to run, ventilates or recirculates the “fresh air stores” in the space using a small variable output heat pump. It incorporates slick controls and internet connectivity.


Plus, I cannot wait to be using it the new high-performance home we are building for occupancy by the summer of 2020.
