Summary

The three-story building addition to the existing Hormel Institute Facility consists of 20 state-of-the-art research labs, offices, and support spaces. The third floor houses a new 7,500 SF SPF animal vivarium.

The facility was designed to meet Minnesota’s SB2030 Energy Standards. A variety of energy savings and ventilation methods were incorporated into the HVAC systems that included:

• HVAC system utilizing thermal decoupling for large equipment areas

• A heat recovery chiller to satisfy simultaneous heating and cooling loads

• High efficiency condensing boilers for low temperature heating hot water

• Cascaded ventilation system and heat recovery

• A combination of fume hood and general lab exhaust airflows allowing for energy recovery of all laboratory exhaust

• Demand based ventilation using occupancy sensors to reduce airflows when spaces are unoccupied

• Reduction of lab air change rates using air quality measurement devices
