P2. Night Ventilation with Building Thermal Mass > Approach

Develop, implement, and demonstrate a control strategy for using night-time ventilation and building mass to reduce cooling requirements and peak cooling demand while ensuring adequate thermal comfort.

• Develop a simulation tool to evaluate a proposed night ventilation control algorithm for packaged air-conditioners. The simulation tool would be developed to accommodate simulation requirements for this project as well as Projects 3.1 and 4.2. It would serve as a screening tool using representative buildings and systems and allowing evaluations in different climate zones.
  
  
• Evaluate the control algorithm with field tests. One of the 12 demonstration sites selected for research on Projects 2.1, 3.1, and 4.2 would be selected to test the algorithm.
  
  
• Compare the field monitoring data and the simulation data and improve the algorithm based on the comparisons.
  
  
• Summarize the results and present recommendations regarding the overall potential for cost savings using night ventilation with building mass in California applications.
