Detailed, hourly simulation modeling and reporting using an FSEC-enhanced version of the widely-respected DOE-2.1E building energy simulation program. FSEC enhancements include: 

  • More accurate computation of heating and cooling system part load performance
  • More accurate prediction of indoor air relative humidity
  • Coil airflow and system sizing impact on heat pump and air conditioner performance
  • More accurate ground contact modeling
  • More accurate attic modeling (including attic ventilation/ reflective roofing and radiant barriers) and
  • Detailed hourly modeling of duct heat transfer and air leakage
  • Hourly prediction of end-use electrical and gas energy consumption for evaluation of peak impacts.
