Direct-Fired Make Up Air and Packaged Units – Stoneyfield Farms Yogurt Plant, New Hampshire

Working with a regional ESCO, we retrofitted the rooftop package units on this well-known facility.   IPMVP-compliant measurement and verification was done on two 7.5-ton package units as representative sample.  Analysis of the M&V data revealed 22% kWh savings on air conditioning, and 13% savings on natural gas-fired heating.
