IVSE Study Goals
Energy Efficiency Goal
To demonstrate that the energy consumption of the advanced HVAC system is at least 30% less than current 10 SEER systems and therefore a 10% improvement compared to 12 SEER systems in both laboratory and field settings in California's varying climate conditions.
Noise Reduction Goal
To confirm the operational noise level of the advanced HVAC is less than or equal to 45 dB(A) in classrooms.
Ventilation System Improvement Goal
To show that the new advanced HVAC system is physically interchangeable with current HVAC models in use on RCs while providing the following:
- Continuous outside air ventilation in amounts that meet the current California Energy and Occupational Codes and ASHRAE 62 Standard
- Real time signals to the ventilation unit that will constantly and continuously ventilate the classroom when it is occupied regardless of temperature
- Indoor CO2 concentration below 1000ppm at all times
- Air velocities and temperatures that lead to acceptable thermal comfort base upon the ASHRAE 55 Standard
