Energy Modeling of Advanced Relocatable Classrooms with Indirect/Direct Evaporative Cooling (IDEC) System

Goal Statement:
To deliver DOE-2 Model Input files for Package B heating, ventilation, and air conditioning (HVAC) Options and a report on initial energy simulations.

Results:

• The characteristics of high-performance relocatable classrooms (RCs) have been defined, modeling assumptions have been developed, and a DOE-2 input dataset has been developed.
• Initial energy simulations using DOE-2 and projected cost savings using current energy pricing information are complete. Final modeling will occur in Year 3.
• The RC energy monitoring datasets from the entire 2001-2002 school year (for both school districts studied) are assembled. Davis Energy Group has started processing the energy data sets, in preparation for third-year modeling.
• We identified two issues that impacted the research plan and affected the RC energy modeling effort:
  • the potential for an improved IDEC heat exchanger
  • the high energy costs of the electric radiant heating system
