EnergyGauge USA has been thoroughly
tested and evaluated. The software has been used to
simulate homes that have been monitored in detail in
the field with excellent results1
and has been subjected to the HERS BESTEST procedure,
also with excellent results.2
The EnergyGauge USA
BESTEST Report is on permanent file with RESNET,
the nation's Accreditor of HERS Providers and Rater
Training Providers. The BESTEST Report is also available
online here.
EnergyGauge USA
provides the following general capabilities:
-
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:3
-
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
- Whole building heating and cooling system sizing
- Energy
code compliance in accordance with the International
Energy Conservation Code (IECC) 1998 and IECC
2000 whole-building performance method.
- Ideal
for evaluation of low energy and Zero Energy
Building Designs.
- Hourly
prediction of solar electric PV system performance.
- Hourly
prediction of solar hot water heating systems.
- Hourly
prediction of end-use electrical and gas energy
consumption for evaluation of peak impacts.
