SOFTWARE DEVELOPMENT
Building Simulation Software Testing
Related Project Experience
GARD provides software that allows customers to analyze proposed system designs for
energy efficiency and cost performance. These software tools include standalone
application development for a variety of software environments as well as extensions to
public domain simulation tools.
GARD's historical and current focus on this area is readily evidenced by our
experience in the building energy analysis field. From an historical
perspective, GARD has been a pioneer in the development of building energy
analysis software beginning with an active role in the creation of the first
public domain hour-by-hour programs in the late 1960's. GARD Analytics personnel
have remained actively involved in the development of subsequent generations of
these applications over the past thirty-five years, and are currently involved
in the testing and support of the next generation of energy analysis programs
called EnergyPlus. This continuity, stretching over almost four decades, brings
an immense depth of understanding to research and development issues relating to
energy analysis and building simulation software.
Recent projects include the following:
- Testing, Support, Software Utilities for EnergyPlus.
Providing ongoing testing and support services during the development of
this next generation building energy simulation program.
Available from the U.S. Department
of Energy.
- Gas cooling equipment models included in DOE-2.
Developed simulation algorithms and FORTRAN subroutines to model desiccant
dehumidifiers, direct-fired absorption chillers, gas engine-driven chillers, and gas
engine-driven heat pumps.
Available in DOE-2.1E and DOE-2.2 from various vendors.
- Simulation library for DesiCalc™ program to analyze desiccant
system applications to commercial buildings.
Developed parameterized DOE-2 simulation input file library to compare the energy
costs of a desiccant dehumidifier against a variety cooling and dehumidification systems
for 10 building types.
Available from www.desicalc.com.
- Simulation library for Gas Cooling Guide™ program to analyze
applications of gas cooling equipment.
Developed parameterized DOE-2 simulation input file library to compare the energy
costs of gas-fired chillers and desiccant dehumidifiers against a variety of competing
systems for 12 building types.
Available from www.interenergysoftware.com.
- Simulation library for Building Energy Analyzer™ program to analyze
CHP applications in commercial and industrial buildings.
Developed parameterized DOE-2 simulation input file library to compare the
energy costs of thermal storage systems, on-site power generation, and
waste heat recovery systems against a variety of competing systems for 12
building types.
Available from www.interenergysoftware.com.
- Compressed Air System Screening Tool (CASST) to perform preliminary
analyses of industrial compressed air systems.
Developed Microsoft Excel™ spreadsheet application to help determine which energy
conservation measures (ECMs) make the most sense for a given industrial compressed air
plant given the plant configuration, loads, and utility costs.
Contact the Energy Center of Wisconsin for additional information.
- Resource Energy Efficiency and Emissions Model (REEEM) used to
evaluate electric utility efficiency and emissions
Developed Microsoft Excel™ spreadsheet application and database containing
monthly data for electric power plants owned by the 52 largest U.S. utilities. REEEM uses
a total fuel cycle analysis to evaluate the seasonal marginal energy efficiency and
emissions per unit of delivered electricity by and by generating plant class for a given
utility.
